CNC machining refers to the processing of objects using CNC machining. CNC index-controlled machine tools are programmed and controlled by numerical control processing language, generally in G code. The CNC machining G code language informs the CNC machine tool which Cartesian azimuth coordinates to select for the machining tool, and controls the feed speed and spindle speed of the tool, as well as functions such as the east-west converter and coolant.

1) There is a problem with the material of the main working parts of the mold, and the material selection is improper. Poor material performance and non wear resistance; The mold steel is unrefined and has a large number of smelting defects; The forging process for convex and concave dies and forging blanks is not perfect, leaving potential heat treatment hazards. 2) Mold structure design issues, unreasonable stamping die structure. The elongated punch is not designed with a reinforcement device, the discharge port is not smooth and there is accumulation, and excessive discharge force aggravates the alternating load borne by the punch.

The wear and tear of hardware fittings is a common occurrence during the use of molds. Although a mold accessory does not cost a lot, it can also cost a lot to wear and tear too quickly and replace frequently. Therefore, to extend the service life of mold accessories, it is necessary to learn to maintain them. Good protection for mold accessories is to save money.

Lathe machining is a part of mechanical processing, and there are two main forms of machining: one is to fix the lathe tool to process unformed workpiece during rotation, and the other is to fix the workpiece and perform precision machining through high-speed rotation of the engineering, and the lateral and longitudinal movement of the lathe tool.
