1. cutting machine

The shearing machine is through the movement of the upper blade and the fixed lower blade, using a reasonable blade gap, the shear force is applied to the metal sheet of various thicknesses, so that the plate is broken and separated according to the required size. Shearing machine belongs to one of the forging machinery, the main role is the metal processing industry, mainly used in the cutting of steel plates.

2. plasma cutting machine

Plasma cutting is a processing method that uses the heat of high temperature plasma arc to melt (and evaporate) the metal part or part of the workpiece incision, and uses the momentum of high speed plasma to remove the molten metal to form the incision.

3. flame cutting

The cost of flame cutting equipment is low and it is the only economical and effective means of cutting thick metal plates, but it has its shortcomings in thin plate cutting. Compared with plasma, the heat affected zone of flame cutting is much larger and the thermal deformation is larger. In order to cut accurately and effectively, the operator needs to have superb technology in order to avoid the thermal deformation of the metal plate in time during the cutting process.

4. laser cutting

Laser cutting equipment can cut stainless steel below 4mm, adding oxygen in the laser beam can cut 20mm thick carbon steel, but after oxygenated cutting will form a thin oxide film on the cutting surface. The maximum thickness of the cutting can be increased to 20mm, but the size error of the cutting parts is large. The price of laser cutting equipment is quite expensive, about 1.5 million yuan or more.

5. Wire cutting

Electrical discharge wire cutting is referred to as wire cutting. It is developed on the basis of electric spark perforation and forming processing. It has not only developed the application of EDM, but also replaced EDM perforation and forming in some aspects. Today, wire-cut machine tools have accounted for most of the EDM machine tools.

6. ultra-high pressure water cutting

Ultra-high pressure water cutting, also known as water knife and water jet, is the high energy (380MPa) water flow generated by ordinary water after multi-stage pressurization, and then cut through a very fine ruby nozzle (Φ0.1-0), this cutting method is called ultra-high pressure water cutting.
