Difference of non-abrasive waterjet and abrasive waterjet

There are many kinds of water classification, to add sand to points: divided into non-abrasive waterjet cutting and abrasive waterjet cutting. Facilities to points: divided into large waterjet cutting and small waterjet cutting. Let's look at the difference of non-abrasive waterjet and abrasive waterjet.

Below we discuss the case from the waterjet abrasive, waterjet different classification.

1, Non-abrasive waterjet

Non-abrasive waterjet cutting is a way to use water directly cutting, non-abrasive waterjet cutting started to be applied to corrugated board business. A large number of users use the non-abrasive waterjet cutting disposable diapers, tissue paper, and automotive interiors. When cutting the tissue paper or paper diapers, non-abrasive waterjet operation generated a small amount of water vapor less than in contact with or artificial respiration cause water vapor. For general non waterjet cutting process caused by unplanned downtime to diapers or tissue paper producers resulted in a large number of economic losses. The water jet device can provide above industrial applications throughout the day, the week, the annual safety use, maintenance operations can be arranged into production.

Non-abrasive waterjet features:

Very fine water jets (usually thickness of 0.1mm to 0.25mm); can be processed very complex graphics; when cutting material loss is very limited; not hot cutting; can cut very thick materials; it can be cut very thin materials, cutting usually very fast, able to cut soft, reflective material (for example, thickness 6mm glass fiber insulation parts), produce extremely small force, simple fixing clamp, all-weather operation.

In the waterjet cutting process, the cutting process the material can be described as a supersonic etching process. Not because of pressure, but because of their speed of water jet itself to cut portions and fine particulate of material. Pressure and speed are two different forms of energy. So, how pressure is converted into water speed of such forms of energy? The answer in a little gem, a high pressure water flow through the gem orifice and the pressure will be transformed into speed.

For standard cutting operation, the non-abrasive waterjet gem orifice diameter in the range of 0.1-0.25mm.

2, Abrasive waterjet

Abrasive waterjet and non-abrasive waterjet exist some differences, non-abrasive waterjet by water jet etching material, and abrasive waterjet by accelerating water jet and sand jet, sand jets accelerated to etch the material, abrasive waterjet energy is non-abrasive waterjet thousands of times. Of course, non-abrasive waterjet and abrasive waterjet applications have their respective areas. No Abrasive waterjets can cut soft materials, abrasive waterjet can cut hard materials, such as metal, stone, composite materials and ceramic materials.

Abrasive waterjet features:

Exceptional universal cutting technology: no hot reaction zone, no mechanical stress, easy to program control, very fine water jets, can process very complex graphics, processing of thin-walled materials, 10 cm thickness of material processing, laminated processing, cutting cause very little chip, workpiece-holding fixture is simple, small cutting force (less than one pound), simply install one cutting head, it can be processed almost all of the work, easy to upgrade from a single cutter head into a multi cutter head, can fast change non-abrasive waterjet into abrasive waterjet, reduce the operation of secondary processing, no noise.

Abrasive waterjet used sand is a hard sand, particularly screening and fine mesh sieve press obtained. The most common sand is garnet sand. Garnet sand is a hard, wear-resistant and inexpensive sand. Different mesh abrasive sand used for different requirements of operation: 120 mesh - Manufacturing smooth surface; 80 mesh - common, general purpose; 50 mesh - cutting faster than 80 mesh, of course, the cutting surface will be more rough.
