Overview of CNC machining.

2023-06-21

The development trend of modern CNC machine tools is high speed, high precision, high reliability, multi-function, compound, intelligent and open structure. The main development trend is the development of intelligent full-function general CNC device with open structure of software and hardware. Numerical control technology is the basis of machining automation, is the core technology of numerical control machine tools, its level is related to the national strategic position and reflect the level of national comprehensive strength. It develops with the development of information technology, microelectronics technology, automation technology and detection technology. CNC machining center is a kind of CNC machine tool with a tool library and can automatically change the tool, and can carry out a variety of machining operations on the workpiece within a certain range.

The characteristics of machining parts on the machining center are: after the machined parts are once installed, the CNC system can control the machine tool to automatically select and replace the tool according to different processes; Automatically change the spindle speed of the machine tool, feed rate and tool relative to the workpiece and other auxiliary functions, and continuously drill, countersink, ream, boring, tapping, milling and other processes of the workpiece machining surface automatically.

Because the machining center can centrally and automatically complete a variety of processes, avoid artificial operating errors, reduce the workpiece clamping, measurement and adjustment time of the machine tool and the workpiece turnover, handling and storage time, greatly improve the processing efficiency and processing accuracy, so it has good economic benefits. The machining center can be divided into vertical machining center and horizontal machining center according to the position of the spindle in space.
