NC machining center is a high-efficiency automatic machine tool composed of mechanical equipment and numerical control system, suitable for processing complex parts. CNC machining center is one of the world's highest output and most widely used CNC machine tools. Its comprehensive processing ability is strong, the workpiece can complete more processing content after one clamping, and the processing accuracy is higher, especially it can complete the processing that many ordinary equipment can not complete, the shape is more complex, the precision requires a single Processing or multi-variety production in small and medium batches is more suitable. The following briefly introduces the advantages of CNC machining centers:
(1) Full-featured CNC machining center
CNC machining center is a kind of full-featured CNC machining machine. It concentrates the functions of milling, boring, drilling, tapping and thread cutting on a single device, giving it a variety of technological means. The machining center is provided with a tool magazine, which stores various numbers of various tools or inspection tools, and is automatically selected and replaced by the program during the processing.
(2) High degree of automation of CNC machining center
After the workpiece is clamped once in the machining center, the digital control system can control the machine tool to automatically select and change tools according to different procedures, and automatically change the machine tool spindle speed, feed amount, tool trajectory relative to the workpiece and other auxiliary functions, which are completed in turn. Multi-process machining on several surfaces of the workpiece, and has a variety of tool changing or tool selection functions.
(3) High utilization rate of CNC machining center
Due to the concentration of procedures and automatic tool change, the machining center reduces the time for workpiece clamping, measurement, and machine tool adjustment, so that the cutting time of the machine tool reaches about 80% of the machine's operating time (compared to 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 part shapes, high accuracy requirements and frequent product replacement.
(4) Higher accuracy of CNC machining center
The machining quality of the CNC machining center is stable, and the production efficiency is high in the case 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. Conventional methods are difficult to process complex profiles, and even machining parts that cannot be observed.
