The characteristics of modern machining centers

Cnc machining center (cnc) is a high-efficiency automated machine tool composed of mechanical equipment and numerical control system for machining complex-shaped workpieces. The machining center is also called CNC. The machining center is equipped with a tool magazine and has an automatic tool change function. It is a CNC machine tool that performs multi-step machining after the workpiece is clamped once. The machining center is a highly mechatronic product. After the workpiece is clamped, the CNC system can control the machine tool to automatically select and replace tools according to different processes, automatically set the tool, automatically change the spindle speed, feed amount, etc., and can continuously complete drilling, boring, Milling, reaming, tapping and other processes, thus greatly reducing the auxiliary process time such as workpiece clamping time, measurement and machine tool adjustment, and has good economic effects on parts with complex processing shapes, high precision requirements and frequent parts replacement. . 

1.Advantages of cnc machining center

After the workpiece is clamped once on the machining center, the digital control 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, the feed amount and the movement track of the tool relative to the workpiece and other auxiliary functions, which are completed in sequence. Multi-process machining on several sides of the workpiece. And there are a variety of tool change or knife selection functions, which greatly improve production efficiency.

 Due to the concentration of the process and the automatic tool change, the machining center reduces the time for clamping, measuring and machine adjustment of the workpiece, so that the cutting time of the machine tool reaches about 80% of the machine start time (only 15-20% for ordinary machine tools); It also reduces the workpiece turnover, handling and storage time between processes, shortens the production cycle, and has obvious economic effects. The machining center is suitable for small and medium batch production with complex parts, high precision requirements and frequent product replacement.

2.cnc 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 equivalent to 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 automatically exchanging tools. By installing different tools in the tool magazine, it can be changed by an automatic tool changer in one setup. The machining tool on the spindle realizes various machining functions such as drilling, boring, reaming, tapping and grooving. The machining center is a real realization; a modern tool with more speed and better provinces, can complete multiple processes in one clamping, with automatic tool change automatic speed automatic feed, high processing precision, high efficiency, high machine tool utilization, especially Suitable for machining multi-surface and complex process parts.
