CNC machining center is an efficient automatic machine tool which is composed of mechanical equipment and CNC system. The CNC machining center is one of the most widely used CNC machine tools in the world. Its comprehensive processing ability is relatively strong. After the workpiece is clamped, more processing content can be completed. The machining accuracy is high. In particular, it can complete many processes that can not be completed by ordinary equipment, and the shape is more complex. The single piece processing or medium and small batch multi-variety production with high precision requirements is more suitable. The following is a brief introduction to the advantages of the CNC machining center:
(1) The function of CNC machining center is comprehensive
The CNC machining center is a kind of CNC machining machine with full function. It concentrates the functions of milling, boring, drilling, tapping and cutting threads on a single device, so that it has a variety of technological means. The processing center is equipped with a knife library, which contains a variety of different types of knives or inspection tools. In the process of processing, the program is automatically selected and replaced.
(2) High degree of automation of NC machining centers
After the workpiece is clamped at the processing center, the digital control system can control the machine tool to automatically select and replace the tool according to different procedures, automatically changing the spindle speed, feed amount, and the tool's movement trajectory relative to the workpiece and other auxiliary functions. Complete the processing of several parts of the workpiece in turn, and there are many kinds of knife replacement or knife selection functions.
(3) High utilization rate of boot up of NC machining center
The processing center reduces the time for loading, measuring, and adjustment of the workpiece due to the concentration of the process and the automatic replacement of the knife, so that the cutting time of the machine tool reaches about 80 % of the operating time of the machine tool(the average machine tool is only 15 to 20 %); At the same time, it also reduces the workpiece turnover, handling and storage time between processes, shortens the production cycle, and has obvious economic effects. The processing center is suitable for medium and small batch production with complex parts shape, high accuracy requirements, and frequent product replacement.
(4) The precision of NC machining center is higher
The machining quality of the CNC machining center is stable, and the production efficiency is higher under the conditions of multi-variety and small batch production. It can reduce the time for production preparation, machine tool adjustment and process inspection, and reduce the cutting time due to the use of the optimal cutting amount. And it can be processed complex surfaces that are difficult to process by conventional methods, and can even process some unobservable processing parts.
