CNC water jet machinery with 380Mpa pump

Water jet cutting machine

Waterjet cutting machine is realized by waterjet with great kinetic energy and high speed. It belongs to high energy beam category as well as laser, ionic beam, electron beam. Among them HP waterjet cutting is the only processing technology which is made in cold state. As a high and new technology, to some extent, it is a revolution in cutting field.

Currently HP waterjet cutting is mainly applied in below areas.

• Application in metallic material cutting

1) To cut the metallic materials used for architectural decoration, such as stainless steel.

2) To make and cut the crust of machine equipments

3) To cut all kinds of metallic spare parts

• Application in glass cutting

1)     To cut the glass of household electrical appliances

2)     To cut glass used in shower room

3)     To cut glass for architectural decoration, craftwork and auto.

• Application in processing tiles, stones and other building materials.

Water cutter is applied in this field much earlier. Currently, the overwhelming majority in this area use it. They focus on artistic matching. At present, tile matching and stone matching have expanded all over the world.  

• Application in composites, bulletproof material, soft material and others

1) With robot arm to cut automotive interior components

2) To cut foam, sponge, paper, rubber, etc.

3) To cut nylon, carpet, etc.

Technical data of water jet cutting machine

The machine has three parts: cutting table, intensifier pump, controller

1.  cutting table:  

bridge style and flying arms style.

The technical data for flying arm is as follows:
Z-axis journey is 150mm
Way of drive : AC Servo
Control accuracy: ±0.01mm
Cutting accuracy: 0.1~±0.2mm
Max moving speed:6000mm/min
X-axis servomotor: 0.75kw 1.0kw 1.5kw
Y-axis servomotor: 0.75kw 1.0kw 1.5kw
Z-axis step motor: 0.9N.m

Main character:
1).Bridge style, has good appearance, reasonable design, great rigidity and stability, well-distributed stress,steady running, high accuracy and safety. The bridge style has strict requirement to the smoothness and parallelism of two Y beams. Our company applies ultra large style milling planer to process the basic surface of guide, which keeps the planeness of installation.

2).X beam of cutting table applies the one-off extrusion forming aluminum alloy

3).Z-axis auto control, has 3-axis linkage control and auto tool setting function.

4).Using ball screw and linear guide from Spain and America, which guarantees the transmission accuracy, high quality and durability.

5).Using servomotor and drive from Japan which have reliable control and good acceleration functions. They run steadily and will not generate low frequency resonance.

6).Over travel and soft limits, double protection functions.
