CNC (Computerized Numerical Control Machine) is an efficient automatic machine tool composed of mechanical equipment and numerical control system for machining complex shaped workpieces. Processing center is also called computer gong. The machining center is equipped with a tool magazine, which has the function of automatic tool change. It is a CNC machine tool that performs multi process machining after clamping the workpiece once. The machining center is a highly electromechanical product. After the workpiece is clamped, the CNC system can control the machine tool to automatically select, replace tools, automatically set tools, and automatically change the spindle speed and feed rate according to different processes. It can continuously complete multiple processes such as drilling, boring, milling, reaming, and tapping, thus greatly reducing the time for workpiece clamping, measuring, machine tool adjustment and other auxiliary processes. The machining shape is relatively complex, and the accuracy requirements are high, Parts with frequent variety change have good economic effect.
Advantages of machining center
After the workpiece is clamped on the machining center for one time, the digital control system can control the machine tool to automatically select and replace tools according to different procedures, automatically change the spindle speed, feed rate of the machine tool, the movement track of the tool relative to the workpiece and other auxiliary functions, and sequentially complete the processing of multiple procedures on several surfaces of the workpiece. And it has a variety of tool change or tool selection functions, which greatly improves the production efficiency.
Because of the centralized process and automatic tool change of the machining center, the time for workpiece clamping, measurement and machine tool adjustment is reduced, making the cutting time of the machine tool reach about 80% of the starting time of the machine tool (only 15-20% for ordinary machine tools); At the same time, it also reduces the turnover, handling and storage time of workpieces between processes, shortens the production cycle, and has obvious economic effects. The machining center is suitable for medium and small batch production with complex part shape, high precision requirements and frequent product replacement.
Machining center and CNC milling machine
The same as the CNC milling machine, the machining center is also composed of computer numerical control system (CNC), servo system, mechanical body, hydraulic system and other parts.
However, the machining center is not the same as the CNC milling machine. The biggest difference between the machining center and the CNC milling machine is that the machining center has the function of automatic tool exchange. By installing tools for different purposes in the tool magazine, the machining tools on the spindle can be changed through the automatic tool change device in one clamping process to achieve various processing functions such as drilling, boring, reaming, tapping, grooving, etc. Machining center is the real realization; It is a modern tool that can complete multiple processes at one time. It has automatic tool change, automatic speed regulation and automatic feed. It has high machining accuracy, high efficiency and high machine tool utilization. It is especially suitable for machining parts with multiple curved surfaces and complex processes.
