How to properly control the speed and accuracy of waterjet cutter?

Waterjet cutter is a kind of equipment that can pressurize ordinary tap water to 250-400mpa by using ultra-high pressure technology, and then spray through a gem nozzle with an inner hole diameter of about 0.15-0.35mm to form a high-speed jet with a speed of about 800-1000m/s. Through the high energy of the water arrow, it is used to cut soft basic materials.

Driven by numerical control technology, numerical control waterjet cutting machine has been widely used. The process of cutting with high-pressure and high-speed water flow is mainly used for two-dimensional shape cutting. CNC water cutting machine can cut metals, ceramics, plastics, stones, glass, carbon fibers and other materials, and can produce complex fine shapes. The key is that this cutting method can remove the material without heat, and make the debris of the material be washed away by the cutting water flow, which improves the cutting efficiency.

On the premise of meeting the precision of waterjet cutting, we can further pay attention to the speed of the waterjet cutter. Because the cutting platform is short, it is difficult to judge whether the high speed is achieved by eyes, so we can use the software simulation function equipped with the servo driver of the cutting machine to check whether the motor speed is high. In the test of cutting speed, there is no need to cut, just increase the acceleration and deceleration.

There is also about the cutting accuracy of waterjet cutter. When the equipment is applied in different industries, the accuracy required is different. Generally, it is required to be less than ± 0.5mm for the construction industry; However, the requirements for automotive reflectors are ± 0 Below Olmm; The cutting requirements for steel plate processing are as low as possible

At present, the cutting accuracy that can be provided by various machinery manufacturers is generally less than ± 0.2mm, but this cannot be seen only from the introduction of the product manual. There should be a complete set of procedures for testing the cutting accuracy during the acceptance, which should be subject to the measurement of the actual cutting product accuracy.
