Precision CNC machine tools|Classification of CNC machine tools - classification according to the functional level of the CNC system
Precision CNC machine toolsAccording to the functional level of the numerical control system, the numerical control system is usually divided into three categories: low, medium and high. This classification method is used more in our country. The boundaries of low, medium and high grades are relative, and the division criteria will be different in different periods. As far as the current development level is concerned, various types of CNC systems can be divided into three categories: low, medium and high-end according to some functions and indicators. Among them, middle and high-end are generally called full-function CNC or standard CNC.
⑴ metal cutting
Refers to CNC machine tools that use various cutting processes such as turning, milling, bumping, reaming, drilling, grinding, and planing. It can be further divided into the following two categories.
①Ordinary CNC machine tools such as CNC lathes, CNC milling machines, CNC grinding machines, etc.
②Machining center Its main feature is a tool magazine with an automatic tool changing mechanism, and the workpiece is processed once. After clamping, by automatically replacing various tools, the machining surfaces of the workpiece are continuously processed on the same machine tool for milling (turning) keys, reaming, drilling, tapping and other processes, such as (building/milling) machining. Center, turning center, drilling center, etc.
⑵ metal forming
Refers to CNC machine tools that use extrusion, punching, pressing, pulling and other forming processes, commonly used CNC presses, CNC bending machines, CNC pipe bending machines, CNC spinning machines, etc.
⑶ special processing
There are mainly CNC wire EDM, CNC EDM, CNC flame cutting machine, CNC laser processing machine and so on.
⑷ Measurement and drawing
There are mainly three-coordinate measuring instruments, CNC tool setting instruments, CNC plotters and so on.
