In the fields of modern microelectronics, information, optics and other fields, precision grinding and polishing of Shenzhen precision parts are very important in order to realize the functions of functional ceramics and crystal materials. For example, semiconductor integrated circuit silicon substrate, ferrite magnetic sheet, gem infrared window, piezoelectric crystal oscillator substrate. In the operation process, the requirements for workers' skills are reduced, and the quality of the processed workpiece is stable and the processing efficiency is high.
Automatic processing eliminates a large number of errors in worker operations, and improves product consistency and productivity. CNC machining of precision parts is different from that of ordinary machine tools. Control information required for NC machining, such as tool path, sequence of various actions, and various auxiliary functions (such as spindle speed, feed speed, tool change, coolant switch) are stored in the control medium in digital form.
And the machine tool is an automatic processing process realized by a numerical control device. Providing equipment and means for various sectors of the national economy has unlimited economic and social impact. Europe, the United States, Japan and other industrialized countries have completed the industrialization process of CNC machine tools, while China started in the 1980s and is still in the development stage.
According to its structural characteristics, the machined parts can be divided into internal shape, shape, curved surface or plane and other parts.
Generally, the plane and locating surface are machined first, and then the hole is machined; Then machine the hole. First deal with simple geometric shapes, then deal with complex geometric shapes; First, machine the parts with low accuracy, and then machine the parts with high accuracy requirements. The point of the compound machining machine tool is that it can greatly shorten the production cycle of the workpiece and improve the machining accuracy of the workpiece. In addition, it can realize completely different machining processes on the compound machine tool. Compound machining is an important technical development direction of CNC machine tools.
