  • The definition of the CNC

    With CNC, each object to be manufactured gets a custom computer program, usually written in an international standard language called G-code, stored in and executed by the machine control unit (MCU), a microcomputer attached to the machine. The program contains the instructions and parameters the machine tool will follow, such as the feed rate of materials and the positioning and speed of the tool's components. Mills, lathes, routers, grinders and lasers are common machine tools whose operations can be automated with CNC. It can also be used to control non-machine tools, such as welding, electronic assembly and filament-winding machines.

  • The introduction of stamping

    Stamping is to rely on the press and die on the sheet, strip, pipe and profile to exert external force, so that the plastic deformation or separation, so as to obtain the required shape and size of the workpiece (stamping parts) forming processing method.

  • The selection method of CNC cutting tool.

    Because the spindle speed and range of CNC machine tools are much higher than ordinary machine tools, the output power of the spindle is also very large, so compared with the previous processing methods, including high precision, high strength, high rigidity, high durability, high durability, dimensional stability, easy to set and adjust CNC machining tools put forward higher requirements.
