The machining center is an automatic tool changing CNC machine tool that has rapidly developed to meet the requirements of labor-saving, time-saving, and energy-saving times. It is a high-tech product that integrates mechanical technology, electronic technology, computer software technology, pneumatic technology, drag technology, modern control theory, measurement and sensing technology, as well as communication diagnosis, cutting tools, and programming technology. It integrates CNC milling machines, CNC boring machines The functions of the NC drilling machine are concentrated on one processing equipment, and Automatic tool changer and tool magazine are added. After the workpiece is installed at one time, the NC system can control the machine tool to automatically select and replace tools according to different processes, and automatically change the machine tool spindle speed, feed rate, tool relative motion track and other auxiliary functions; Complete multi sided and multi process machining in sequence, such as end plane, hole system, internal and external chamfering, circular groove, and thread tapping. Due to the ability of the machining center to complete multiple processes in a centralized manner, it can reduce the time for workpiece clamping, measurement, and adjustment, reduce workpiece turnover, transportation, and storage time, and make the cutting utilization rate of the machine tool twice that of general machine tools Up to 01 times. So, the machining center not only improves the machining accuracy of the workpiece, but also is the most productive and automated comprehensive machine tool in CNC machine tools.

Due to the rapid development of electronic technology and the emergence and application of various high-performance sensors, the functions of machining centers are becoming increasingly perfect. These functions include: monitoring tool life, monitoring tool wear and damage, monitoring cutting status, monitoring, alarming, and automatic shutdown of cutting abnormalities, automatic detection and self diagnosis, and adaptive control functions. The machining center is also organically connected to an automatic pallet carrying accompanying fixtures, and can perform automatic chip processing, making it a key equipment and basic unit for flexible manufacturing systems, computer integrated manufacturing systems, and automated chemical plants.
