As a new type of cutting technology, CNC waterjet cutting machine has the characteristics of strong adaptability, high cutting precision, no thermal effect, no burr, no pollution and so on. Its main working principle is: a great stream of water and a very small area of ​​impact to complete the cutting of the material. CNC waterjet cutting machine is also welcomed by customers. Today, I come to join you to find out the difference between the waterjet cutting machine and the traditional cutting machine.
Waterjet cutting and milling
If you want to cut the periphery of the workpiece and make holes, instead of using blind holes, drilling, and threading methods, you might as well choose a faster, easier, and cheaper sand knife. The main reason is that we only need to cut a piece of water to complete the cutting of the workpiece without having to grind all the metal into pieces. When it is necessary to cut a high-precision workpiece, the sand knife can be used to produce a machine tool that is close to the finished product, and can be processed once without thermal effect. In addition, the waste generated by the sand knife is usually more valuable because it is a whole piece rather than debris and can be reused.
Waterjet cutting flame cutting comparison
Obviously, flame cutting is a hot process that will produce a thermal effect on the finished product. The use of a sand knife is usually better at the surface, and there is no scum on the back of the workpiece, which can reduce secondary processing. There is no limit to the thickness of the sand knife, and the layout spacing of the cutting graphics can be reduced to save material costs.
Waterjet cutting and laser cutting
The investment in laser cutting equipment is large. Most of them are currently used for cutting thin steel plates and some non-metallic materials. The cutting speed is faster and the precision is higher. However, laser cutting will cause arc marks at the kerfs and cause thermal effects; Material laser cutting is not ideal, such as aluminum, copper and other non-ferrous metals, alloys, especially for thick metal sheet cutting, cutting the surface is not ideal, or even cutting. At present, research on high-power laser generators is trying to solve the cutting of thick steel plates, but the cost of equipment investment, maintenance, and operation consumption are also considerable. The water cutting investment is small, the operating cost is low, the cutting material has a wide range, the efficiency is high, and the operation and maintenance are convenient.
Waterjet cutting and plasma cutting
Plasma cutting has obvious thermal effects, low precision, and it is not easy to perform secondary processing on the cut surface. Water cutting is cold cutting, no heat distortion, good cutting surface quality, no secondary processing, and easy secondary processing if needed.
Waterjet cutting and wire cutting comparison
For metal processing, wire cutting has higher precision, but the speed is very slow. Sometimes there are other methods for perforation and threading to cut, and the cutting size is very limited. Water cutting can punch and cut any material. , Cutting speed, processing size and flexible.
