Machining center (MC) is a kind of automatic tool changing CNC machine tool, which adapts to the requirements of labor-saving, time-saving and energy-saving. It integrates mechanical technology, electronic technology, computer software technology, pneumatic technology, etc It is a high-tech product of drag technology, modern control theory, measurement and sensing technology, communication diagnosis, tool and programming technology. It integrates the functions of milling machine, drilling machine and boring machine. It is an efficient and highly automatic machine tool controlled by computer. Because the machining center has a variety of tool change or tool selection functions and automatic workbench exchange device (APC), after one clamping, it can automatically carry out drilling, reaming, reaming, boring, tapping, milling and other processes of the workpiece automatically, and automatically complete or nearly complete more than sequence processing of multiple planes or angles of the workpiece, so as to greatly improve the production efficiency and white degree.
Because the machining center can greatly reduce the workpiece clamping, measuring and machine tool adjustment time, reduce the turnover, handling and storage time of the parts, the cutting time utilization rate of the machine tool is 3-4 times higher than that of the ordinary machine tool; moreover, the machining center has better additive consistency, and can eliminate the human interference in the process flow compared with the single machine and the personnel operation mode, and has higher production Production and stable quality, especially the processing shape is more complex, high precision requirements, varieties change frequently, more economic.
With the rapid development of electronic technology, the appearance and application of various sensors with good performance make the function of machining center more and more perfect. These functions include: tool life monitoring function, tool wear and damage monitoring function, cutting state monitoring function, cutting abnormal monitoring, alarm and automatic stop function, automatic detection and self diagnosis function and adaptive control Control function, etc. The machining center is also connected with the automatic pallet carrying the accompanying fixture, and can cut the eyebrow 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
