Machining center (MC) is a kind of automatic tool changing NC machine tool which is developed rapidly to meet the requirements of labor-saving, time-saving and energy-saving era. It is a combination of mechanical technology, electronic technology, computer software technology, pneumatic technology Drag technology, modern control theory, measurement and sensing technology, communication diagnosis, cutting tool and programming technology are high-tech products. It integrates the functions of milling machine, drilling machine and boring machine. Automatic tool changing device is added. It is a highly efficient and automatic machine controlled by computer. Because the machining center has a variety of tool change or tool selection functions and automatic workbench exchange device (APC), it can automatically drill, ream, ream, bore, tap thread, mill and other multi process processing on the workpiece after one clamping, and automatically complete or nearly complete the multi process processing of multiple planes or angles of the workpiece, so as to greatly improve the production efficiency and the degree of automation.
Because the machining center can greatly reduce the workpiece clamping, measuring and machine adjustment time, reduce the turnover, handling and storage time of the workpiece, so that the cutting time utilization rate of the machine tool is 3-4 times higher than that of the ordinary machine tool; and the machining center has a good consistency, compared with the single machine and man-made operation mode, it can eliminate the human interference in the process flow, and has a higher productivity Production and stable quality, especially when processing 1000 pieces with complex shape, high precision and frequent variety change, it has good economy.
With the rapid development of electronic technology and the appearance and application of various sensors with good performance, the functions of machining center are becoming more and more perfect. These functions include: tool life monitoring function, tool wear and damage monitoring function, cutting state monitoring function, abnormal cutting monitoring, alarm and automatic shutdown function, automatic detection and self diagnosis function and adaptive control function And so on. The machining center is also organically connected with the automatic supporting plate with accompanying fixture, and can cut eyebrows automatically, which makes the machining center become the key equipment and basic unit of flexible manufacturing system, computer integrated remanufacturing system and automatic chemical plant
