At that time, most of the domestic high-end CNC lathes were introduced from abroad, and trust was followed by the development of scientific skills. The precision of CNC machine tools produced in China would be higher and higher, and they would certainly satisfy their own needs in the future. Speaking of the reason for the development of CNC lathes in China, it is primarily due to the characteristics of CNC lathes. CNC lathes have the following advantages over traditional machine tools:
1, high yield
The CNC lathe can effectively reduce the processing time and assistant time of parts. The scale of the spindle speed and feed of the CNC lathe is large, allowing the machine to perform powerful cutting with a large amount of cutting. In addition, in cooperation with the tool magazine of the machining center, it is now possible to carry out continuous machining of multiple processes on one machine tool, reducing the turnaround time of the semi-finished products and improving the yield.
2. Use production for modernization
The processing of CNC lathes can accurately estimate the processing time in advance. The tools and fixtures used can be standardized, modernized, and the standardization of processing information can be easily completed. At that time, it has been organically combined with computer aided planning and manufacturing (CAD/CAM). , is the foundation of modern integrated manufacturing skills.
3, stable and reliable processing quality
Processing the same batch of parts, on the same machine tool, under the same processing conditions, using the same tool and machining program, the tool path of the tool is completely the same, the part's consistency is good, and the quality is stable.
4, highly flexible
Processing parts on CNC lathes depends primarily on the machining process. It is not the same as a general lathe. It does not have to be manufactured, many molds and fixtures are replaced, and the machine tool is often adjusted from scratch. Therefore, CNC lathes are suitable for occasions where the processed parts are frequently replaced, that is, the production of suitable single pieces, small batches of commodities, and the development of new products. Then the production preparation cycle is shortened, and the cost of many skill sets is saved.
5. Improve working conditions
Before CNC lathes are processed by CNC lathes, they are programmed and initiated. The machine tool can then be actively and continuously processed until the machining is completed. What the operator needs to do is input of the program, modification, part loading and unloading, tool preparation, observation of processing conditions, inspection of the parts, etc. The labor intensity is greatly reduced, and the machine operator's labor tends to intellectual work.
6, high precision machining.
CNC CNC lathe processing accuracy can reach 0.05-0.1MM, CNC CNC lathes are controlled by digital signals, each pulse output signal from CNC equipment, the machine moving parts move a pulse equivalent (usually 0.001MM), and The reverse gap of the feed chain of the machine tool CNC CNC lathe and screw pitch average error can be compensated by the CNC equipment. Therefore, the CNC machine tool positioning accuracy is relatively high.
