The beauty of the water jet cutting of glass art

In home decoration, when we choose the decoration of kitchen, walls will often choose some pretty patterns, such as the bathroom window we will select some patterns of conditioning, so it seems like the owner is more romantic, elegant, let people pleasing. The guests can enjoy the gentle temperament of the owner, and therefore the first choice of many people. Among them our waterjet a credit. These beautiful glass art is how to cut it? Let us see.

Glass cutting provides many new applications for water jet system, and enables the creation of sculptures and works of art into a new world. Although over the years it has been applied to gas blast texturing process water jet cutting of some details of etching and glass, but because of work pressure of gas is generally about 0.5MPa, therefore operating speed is too slow, for certain industrial applications little significance. And the application of abrasive water jet machining, its jets have the ability to cut off all material encountered, it is particularly suitable for cutting composite materials, one of which is laminated glass.

In the glass cutting, the need to pay attention to the brittleness of the glass, the workpiece must be carefully supported, in order to avoid uneven support surface of the bending stress generated in the glass, the role of the cutting point is similar to a stress concentration point. When before cutting the glass the start of the perforation, because of stop the jet, it may lead to the generation and propagation of cracks. However, such a composite material after cutting along the contour line does not affect the properties of the material, especially in cutting thicker material the advantage is more prominent. The processing of the traditional processing methods for the safety glass which a layer of plastic between two layers of glass is first cut with a diamond grinding wheel to carve grooves on the surface, and then use the impact to cut, the consumption of interlayer material is 30%, and cut with abrasive water jet through three layers of different materials with no deviation, this issue is resolved immediately. Therefore it is suggested that under the condition that the potential penetration, the jet pressure should be 70 ~ 80MPa, until the perforation is completed the jet pressure should not be raised to the actual cutting pressure. In this way, the crack caused by the pressure will not cause the whole plate of the scrap, but produce localized surface debris, through reasonable arrangement of cutting path can avoid the impact on the performance and appearance of the finished product.

In addition, for certain special purposes after the heat treatment of prestressed glass material need special treatment. Due to the influence of prestress, the end of any crack will produce a large enough stress concentration, such materials typically will smash due to cracks, so based on this reason is not recommended to use water jet cutting similar materials. When the jet completely divergent in the slit edge will have undesirable burrs, when cutting the workpiece spatter grains may scratch the workpiece and cause a threat to the operator, which must be observed and prevention.

Glass products are the most common in our lives, waterjet is one of the "behind the scenes operatives", it brings us beautiful experience and spiritual perception. Waterjet brought us beautiful art to enjoy.

In the field of abrasive waterjet, machining abrasive cutting, the application is more extensive, have been involved in the stone, glass, metal, composites, building ceramics, bulletproof glass, and other industries. Such as iron ore used the ore conveying pipes, because the tube is coated with a layer of composite ceramic to enhance wear resistance, but the tube and therefore becomes difficult to process, by machining is not tool hardness not enough, it is the result of too much vibration and damage machining plating ceramic layer, to solve this problem of waterjet is the best choice for cutting tools.

1996 Domestic waterjet officially on the market immediately attention by all sectors of society, and quickly widely used in building ceramics and stone industry. Used in deep processing of construction ceramics and stone, get great economic benefits. It has developed into a mature processing means.

Compared with traditional cutting methods, waterjet cutting mainly has 7 advantages:

1, Cold cutting means - to avoid the effects of thermal distortion, material hardening and the stress of the material.

2, Without or a small, simple clamping device can be OK.

3, Without material limitation, it can cut almost any material (toughened glass, tungsten carbide).

4, The complicated pattern, thick, difficult to cut, fragile and sensitive to heat the materials, most suitable for waterjet cutting.

5, With a narrow kerf, cut smooth, no burrs, no need secondary processing cutting surface, save material, reduce costs (titanium alloy).

6, For precise contour cutting.

7, No sparks flying etc. when cutting. And there is no dust and harmful gas pollution environment during the cutting process, so high pressure water jet cutting technology also has environmental protection significance.

How to maintain waterjet

With the popularity of the promotion, the use of water jet cutting machines are becoming increasingly widespread, so how to maintain water jet in daily use?

Step 1: waterjet cutting machine familiar with the flow of the nozzle. Open waterat at low pressure and observed. The water should be symmetrical, its width depends on the type of nozzle. Ruby and sapphire waterjet nozzle flow is slightly wider; diamond nozzle flow is narrower and more coherent. If the water flow began to widen, said nozzle is damaged, it should be replaced immediately. Damaged nozzle (or misaligned pipes) will cause internal damage to the cutting head.

Step 2: Periodically check the cutting head whether wear or damage (often due to accidental contact with components or fixtures caused). For example, the mixing tube accidentally contact with the fixture will cause damage to the nozzle nut and internal parts maintain the alignment of mixing tube.

Step 3: Check the system and keep it in top operating condition, so that the waterjet cutting operations more efficient, and extend the life of its components. Periodic inspection and replacement of sand delivery system consumable parts, such as pipes and fittings. Make sure the sand delivery system components under the bottom of the miniature hopper are not exposed to any air. When checking this, disconnect sand delivery pipeline from the mini hopper bottom of the joint, manually open the jet and the thumb attached to the end of the transfer line of sand. You will feel a sufficient (but not excess) vacuum exist, which may make the thumb tip dented. Insufficient vacuum may indicate the cutting head inlet is blocked, or sand delivery pipeline cracks, and must be addressed in order to give full play to the efficiency of the system.

Waterjet cutting equipment has its own unique cutting advantages

Waterjet cutting equipment has its own unique cutting advantages, so waterjet technology is recognized worldwide as the most common and the fastest developing technology. Relative to other cutting technology, waterjet does not produce toxic or harmful gases or liquids, and do not produce toxic or harmful substances or vapors. After waterjet machining in a workpiece surface will not produce thermal reaction area or mechanical stress remains. Waterjet is indeed a universal, high capacity cold cutting technology.

Before selecting a waterjet cutting equipment, we are always on the performance of analysis and comparison, we will compare it with other cutting methods, such as laser cutting, plasma cutting, wire cutting and other traditional cutting methods. Waterjet cutting technology does have its unique, significant advantages:

1, The cutting quality is excellent

Waterjet cutting is a cold processing method, water jet cutting will not wear and small radius, can process a small arc having a sharp edge contour. Process itself is no heat generated and cutting force is small, processing surface does not appear in the heat affected zone, the organizational structure of the natural material incision does not change, it is almost non-existent thermal and mechanical stress and strain, the cutting gap (pure water cutting of incision of approximately 0.1mm to 1.1mm, sand water mixed cutting the incision is about 0.8mm to 1.8mm. with the sand tube diameter flaring, the incision is larger) and cutting beveling very small (mostly see the good parts of unilateral cut quality hypotenuse between 0.076mm to 0.102mm), no secondary processing, no cracks, no edges, no scum, so the cutting quality is excellent. Whether ordinary metals such as steel, stainless steel, copper, titanium, aluminum alloy, etc., or non-metallic, such as stone, ceramics, glass, rubber, paper and composite materials, can apply.

2, Clean and environment protection no pollution

During cutting process do not produce arc, dust and toxic gases, operating environment clean, to meet stringent environmental requirements.

3, Saving cost

Waterjet cutting system produces the minimal lateral and longitudinal forces, will not produce thermal effects or deformation or subtle fracture, no need secondary processing, can drilling also can be cut to reduce the cutting time and manufacturing costs.

Important parts of waterjet cutting machine

The key system of CNC waterjet is the ultra-high pressure water jet generator (commonly known as "high-pressure pump"), because a long time of working under conditions of alternating stress significantly, fatigue life is seriously affected, is the weak link in the waterjet cutting machine. Thus, EHV components manufacturing unlike conventional mechanical parts, materials selection, heat treatment requirements, special treatment process, etc., are very different. Existing waterjet cutting machine manufacturers, few master this technology.

1, High pressure system of waterjet cutting machine

This is closely related with the cutting materials, mainly to see the variety of materials, thickness, cutting surface quality and the cutting speed requirements. For example, 300 MPa high-pressure system can be used for cutting hard materials thickness in 30 mm or less; if the material rigid relatively high, you can choose 380 MPa high-pressure system, mainly because of its cutting ability, cutting surface quality, cutting speed and other aspects of comparative advantage.

2, CNC working platform of waterjet cutting machine

Equipment's CNC working platform mainly cantilever and gantry type, the advantage of the former lies in its motion institution and cutting platform is isolated, each other will not be affected, for the material size irregular, loading and unloading ways unfixed is very suitable; while the latter is just the opposite.

In the end to choose which kind, still need according to the size of the cutting materials. But KOS industrial equipment suggested that if you buy equipment is mainly used to undertake external cutting, cantilever CNC cutting platform can meet the requirements.

3, Other optional items of waterjet cutting machine

In addition to the two mentioned above, the waterjet cutting machine soft water processing, automatic sand delivery system are also very important, no point can not be ignored. According to the above description, in reference to their own actual situation, combination together of each part purchased, then, it is a waterjet cutting machine can meet the requirements.

The high speed production efficiency of water jet cutting

Waterjet is mainly used for material cutting, water jet is actually a water flow, for cutting hard material it is how to do it? Although it is difficult to imagine, but it really is done, and complete effect is very good.

Waterjet this water flow is not ordinary water, but it is pressurized by a high pressure pump, then through the water jet nozzle made of some advanced carbide, sapphire and diamond to spout, so for cutting material easily. Of course, which also includes strict requirements on various aspects of water, pipes, nozzles and the like.

Such as pipes, due to the water need to have a high pressure to cut off the hard material, so the pipe must be followed to withstand extremely high pressures. This pressure is far greater than 700 MPa, that is, the pressure of the thin plate itself can withstand. And waterjet used water is also required, need to add the right amount of soluble emulsified oil, once as high as 1700 MPa pressure, high-pressure water spray to cut materials as the knife will become much easier.

1, Full-time cutting

This cutting method is to use a professional programming nesting software on a computer for entire plate and remaining material plate of programming nesting, and then by the cutting equipment for full-time cutting, which can effectively avoid programming nesting in CNC system , affecting the processing process, thereby reducing the production efficiency of the cutting machine.

2, High efficiency cutting

Mainly to the combination of these two methods, in the programming nesting software and CNC system to implement the co-edge, continuous cutting, borrow edge, bridging and other cutting processes, which is very favorable for reduce preheat perforation, so that the cutting equipment productivity will be increased, achieve the goal of high efficient cutting.

3, Automatic cutting

Automatic cutting process is mainly carried out in the CNC system, different from the traditional way of manually cutting, this process can be very good realization of automatic perforation and automatic cutting, productivity will be significantly improved.

4, High quality cutting

In the pursuit of efficiency but also pay attention to quality, high-quality cutting is a kind of cutting mode in programming nesting software and CNC system. It can remove excess entity, to avoid empty running and repeat cutting process, in order to ensure cutting machine smooth high-speed cutting, can also guarantee the cutting part closed, without distortion.

So many ways there is always a cutting method appropriate for your actual production needs, and every kind to improve the cutting equipment productivity are very effective.

Composition and advantages of CNC Waterjet Cutting Machine

A CNC water jet cutting machine consists of three parts: ultra high pressure water jet generator (high pressure pump), CNC machining platform, jet cutting head.

1, Ultra high pressure water jet generator (high pressure pump)

As the waterjet power source, the current common is the hydraulic motor driving the supercharger to produce ultra-high pressure water jet technology solutions. Ordinary tap water pressure increases to several tens to hundreds of MPa (1MPa approximately equal to 10bar), through the waterjet nozzle injection, with a very high kinetic energy.

2, Jet cutting head

High-pressure pump only through the beam nozzle to achieve cutting function. Nozzle aperture size determines the pressure and flow. Meanwhile, the nozzle also has shaped effect. Jet cutting head has two basic forms: one is the completion of pure water cutting, one is the completion of abrasive cutting. Abrasive cutting head, it is based on pure water cutting head, with an abrasive mixing chamber and hard nozzle configuration.

3, CNC machining platform

Currently, CNC waterjet mainly cutting flat plate. Cutting platform choose the rolling linear guide and ball screw as transmission, under the precise control of the NC program and control motor precise X-axis and Y-axis two-axis motion or alone motion, driving the cutting head to achieve a straight line and arbitrary curves cutting.

Waterjet cutting machine advantages:

1, Versatility, almost all materials can be cut.

2, Waterjet is a cold cutting, does not produce thermal effects when cutting, no distortion, no adhering slag, no erosion, will not change the physical and chemical properties of the material.

3, Small cutting slit, with the cooling cutting characteristics, can improve material utilization.

4, Cutting medium only water and natural abrasive, cutting process does not produce other substances, it is clean and green cutting process.

5, After cutting, the cutting surface is smooth and tidy, will not damage the cutting object during the cutting process, can realize cutting operation that many cutting tools can not be achieved.

Waterjet cutting machine cutting effect is obvious

High machining accuracy, cutting width is only 0.10.8 mm, can be processed in the face of complex parts. After machining the parts of the cut is smooth and tidy without trimming. Especially for processing easy thermal deformation of materials, waterjet has more unique advantages.

Waterjet cutting machine of the cutting effect is obvious, but do you know what's the benefits of waterjet cutting machine? For people who have not used, it may be only through the understanding of the waterjet that feel the waterjet cutting machine cutting effect is good only.

In fact, in the cutting effect of the point of view, the waterjet cutting machine of the waterjet cutting effect has three advantages, one of which is less burr. Because when waterjet cutting is used abrasive sand, this cutting method helps to reduce the cutting burrs. In addition to the less burr, as well as good cutting quality and environmental protection.

And in addition to these three advantages of waterjet cutting effects, the benefits of using water jet cutting machine has another seven. For example, its cutting range is still very large, and the processing time does not produce high temperature; if you want to process different shapes of materials, replace the waterjet nozzle can solve the problem without tool change.

Now in the market of our country, has grown from single cutting apparatus developed into various kinds of industry now. And cutting products in the industry to meet the basic needs of the market, and for the cutting machine market demand in recent years, also have been fixed.

And the before use mostly are metal cutting equipment, in recent years it has changed. With the appearance of waterjet cutting machine, the application of the waterjet cutting machine is gradually expanded, and the market is also gradually mature. However, the waterjet cutting function in the past few years into a growth stage of development, still have to depend on China's economy has developed rapidly reasons.

Unlike the cutting tool wear problems that exist, mixed with the water jet abrasive and waste water can be recycled, and equipment relatively simple, processing low interest rates. Vibration and noise caused by processing is very small, chip volume is only 15% -20% of machining and debris go with the flow, will not flying and injuring the operator.

Waterjet cutting speed according to the specific circumstances

Waterjet as a superior cutting manner and high-tech machinery, with unique cutting characteristics favored by the majority of consumers. Waterjet cutting applications are increasingly widespread. However, many consumers in the purchase of waterjet, often have some misunderstandings, that misunderstanding is based on not very understanding of the product.

Understanding of the water jet cutting speed.

Waterjet cutting speed is a very complex issue, it is the result of many factors constituted. Many consumers are very concerned about the exact value of the cutting speed, but it just can not be accurately measured. Under normal circumstances, the material cutting speed of different materials and thicknesses is certainly not the same, if just from this point of view, the cutting speed can be calculated. But there are other factors when cutting, such as: sand tube, gem orifice. Sand tube aperture is one of the factors affecting the cutting speed, large aperture sand tube under normal pressure, the stronger cutting ability, the speed is fastest.

Secondly is the sand tube and gem orifice service time, because with high-pressure water on sand tube and gem orifice continue to erode, its aperture will change, causing the water pressure and the water column shape changes, thus affecting the cutting quality and speed. The service time different between the two, the speed change is also different.

Thus, waterjet cutting speed can not accurately measure, but according to the specific circumstances, and manufacturers can provide the approximate speed of this product, consumers in actual use can continue to accumulate experience, for the accurate value of the cutting speed to experience judgment.

How much do you know about waterjet parts sand tube?

Waterjet parts sand tube is an important part of the water jet cutting machine, high pressure water in its body is changed into people want flow rate and flow path, so as to achieve the purpose of arbitrary cutting mosaic materials. Under the ultra-high pressure, waterjet parts sand tube internal working environment is very bad, in working process is easily damaged, which requires the sand tube inner wall of the structure, material and performance to reach certain indicators, to complete its work task.

1, Structure: Structurally, waterjet parts sand tube design is not complicated, mainly by the tapered end and cylindrical side configuration, size is determined according to actual needs.

2, Materials: Because of the special requirements of the work environment, waterjet parts sand tube material must have good wear resistance, strong hardness, appropriate toughness, good bending resistance, so as to adapt to the high-speed friction. Currently, nano tungsten carbide steel is the preferred material of making sand tube.

3, Wear forms: from physics point of view, the upper cone lower column design principle of sand tube is to improve the wear resistance of sand tube. In addition to wear resistance will affect the extent of the waterjet sand tube damage, wear form is one of the main factors, at the time of production of waterjet sand tube, inner wall to be smooth and mellow, to minimize the presence of friction factors, which is the key also ensure that the waterjet sand tube length of life.

Observe the flow of the gem nozzle, open the water flow in the low pressure state. Water flow should be symmetrical, its width depends on the type of nozzle; the flow of the ruby and sapphire nozzle is slightly wider, and the flow of the diamond nozzle is narrower and more coherent. If the water flow began to widen, the nozzle is indicated for damage and should be replaced immediately. Damage to the nozzle (or misalignment of the pipe) will cause internal damage to the cutting head.

Machine longitudinal and transverse beam

Use the computer manual function to move the longitudinal and transverse beams, to confirm the longitudinal and the transverse beams no abnormal noise.

Cutter head sand supply system

Regular inspection and replacement of consumable parts of the delivery system, such as pipes and fittings, to ensure that any parts of sand supply system below the bottom of the mini hopper are not exposed to the air. When this check, from the mini hopper bottom joint disconnect the sand delivery pipeline, manually open the jet and the thumb attached to the end of the sand delivery pipeline, you will feel adequate (but not excessive) vacuum exists, which may make thumb tip dented. The vacuum insufficient may indicate that the cutting head inlet is blocked, or sand delivery pipeline cracks, and must be solved in order to give full play to the efficiency of the system.

Check the system and keep it in top working condition, make waterjet cutting operations more efficient, and extend the life of its components.

How to choose abrasive for waterjet cutting machine

Although waterjet equipment is the use of ultra-high pressure technology to ordinary tap water pressure to the high pressure (usually 250--400Mpa), then ejected through a very fine diameter gem orifice, forming speed of about 800-1000m/s high-speed jet, commonly known as water arrows. For cutting material, but with pure water energy, can cut soft base materials. Waterjet cutting ability ia related to the abrasive, and if you want to cut hard materials, you need to add the right amount of abrasive in water. Specifically how to choose abrasive and Here simple explain. Let's look at how to select waterjet cutting abrasive.

To be able to cut hard materials, it is necessary to add abrasive in the high-pressure water. The abrasive effect is used to improve the cutting performance. Enlarge particles, there are a lot of edges on it, it is these edges like a sharp blade driven by high-pressure water continuously toward the workpiece form a strong cutting force. The sand used was blunt their edges, and thus loses its cutting ability, so for used abrasive no longer recycling.

In order to make the cutting section of the workpiece relatively smooth, uniform, requires the abrasive flow is good and can be continuous, uniform supply, so the sand particle size have more stringent requirements, too large particles have poor mobility, and easy to plug the pipe; too small particles, cutting ability reduced. When the abrasive contains larger size debris will lead to poor abrasive flow, thereby reducing the cutting ability; when the abrasive contains tiny particles of dust, the dust will be assembled and attached to the pipe wall, especially pipeline bend, thus impeding the flow of abrasive, cutting capacity will be reduced. For these reasons, the abrasive used in the waterjet cutting shall be strictly filtration screening, screening at least twice, once to remove large particles and debris, once to remove very small particles of debris. In the use of water jet cutting machine according to the needs to choose different abrasives, which will help improve cutting efficiency.

Waterjet cutting machine use concerns

Waterjet is the device often used in the cutting process, and then use waterjet, simple operation can achieve the ideal cutting effect. But the premise is to comply with strict operational procedures and in fact territorial arrangement at work, there are many things to consider, we must attach importance to.

As a user of waterjet, there is a problem of great concern, and how much is that that the waterjet cutting speed. In fact, this question is difficult to answer, which includes a lot of factors, so it is impossible to accurately measure. But in fact, waterjet cutting speed can still be calculated by a certain way, how to do it?

When calculating the waterjet cutting speed, but also by virtue of the accumulation of experience in actual use to judge models, the results thus obtained will be relatively accurate. In the clear water jet cutting speed, the real implementation of the work efficiency will be greatly improved.

First significantly may affect the waterjet cutting speed all the factors, including the material, thickness, angle, sand tube aperture etc., because the general speed is due to the emergence of these different changes. Generally large diameter sand tube under normal pressure, cutting capacity is relatively strong, so the cutting speed is the fastest.

In order to further improve the service life of the water jet sand nozzle, to be guaranteed for tightness, just use two hands to touch uneven pressure parts on both ends of the waterjet we can determine, and usually cases are the end of the high temperature sealing effect will be quite lacking.

In the process of using waterjet, should also pay attention to the linkage of pipeline. In order to prevent the phenomenon of water leakage, can be in the head of its pipe thread three higher than the screw pad, so as to prevent the impact of cutting efficiency. In addition, determining waterjet fault is also very important, especially when it comes to water or oil, the correct determine the fault not only help to solve timely, the lifetime and energy consumption of waterjet are influential.
