1. Working principle
The ultra-high pressure water jet cutting machine is to pass ordinary water through an ultra-high pressure pressurizer to pressurize the water to 3000 bar, and then generate a water jet about 3 times the speed of sound through a water nozzle with a channel diameter of 0.3 mm, which is controlled by a computer It can easily cut any pattern of soft materials, such as paper, sponge, fiber, etc. If sand is added to increase its cutting force, almost any material can be cut.
2. Features:
1. There is no restriction on the cutting direction, and all kinds of special-shaped processing can be completed;
2. The lateral force generated by the water jet on the workpiece is extremely small, which can reduce the setting time and save the cost of using fixtures;
3. Waterjet processing will not produce thermal deformation, no secondary processing is required, which can save time and manufacturing costs;
4. The waterjet cutting speed is fast, the efficiency is high, and the processing cost is low.
3. Advantages:
1. Can easily cut stainless steel plate or hard marble, granite, etc., for those who are due to other
Materials that are difficult to cut such as aramid, titanium alloy and other composite materials are ideal or the only processing methods.
2. There will be no cracks when cutting, and it can cut materials with very narrow gaps. Generally speaking, the cut of pure water cutting is about 0.1mm to 1.1mm, and the cut of sand cutting is about 0.8mm to 1.8mm. As the diameter of the inner hole of the sand nozzle increases, the incision becomes larger.
3. Can be cut in all directions, including various shapes, angles or slopes;
4. There is no need for secondary processing such as edging, and the flying dust can be reduced during the cutting process and the working environment can be improved.
Fourth, the form of water cutting and the composition of water cutting machine tools:
The form of water cutting is divided into water quality, including pure water cutting and abrasive cutting; from the pressure method, there are hydraulic pressure and mechanical pressure; from the machine tool structure, there are gantry structure and cantilever structure.
A complete set of water cutting equipment consists of ultra-high pressure system, waterjet cutting head device, waterjet cutting platform, CNC controller and CAD/CAM cutting software, etc.
