CNC machine tool processing is a kind of high precision, high-efficiency automatic machine tool, using CNC machine tool processing can improve processing efficiency, create more value, get rid of the backward processing technology, CNC lathe processing technology and ordinary lathe processing technology is similar.
Here is the content list:
l High productivity
l High machining accuracy
l Highly flexible
l The processing quality is stable and reliable
l It is conducive to the modernization of production management
l Improving working conditions
CNC machine tools can effectively reduce the processing time and auxiliary time of parts. The range of spindle speed and feed rate of CNC machine tools is large, which allows the machine tools to carry out strong cutting with a large cutting amount. The rapid movement and positioning of moving parts and high-speed cutting of CNC machine tools reduce the turnover time of semi-finished products and improve production efficiency.
The machining accuracy of the NC machine tool can reach 0.005 ~ 0.1mm generally. NC machine tool is controlled by the digital signal. For every pulse signal output by the NC device, the moving part of the machine tool moves one pulse equivalent (generally 0.001mm). Moreover, the average error between the reverse clearance of feed transmission chain and the pitch of lead screw can be compensated by NC device, The positioning accuracy of the CNC machine tool is relatively high.
In order to ensure the surface accuracy of the workpiece, it mainly depends on the processing program. Unlike ordinary machine tools, it does not need to manufacture and replace many tools and fixtures, and it does not need to adjust the machine tool frequently. Therefore, CNC machine tools are suitable for frequent replacement of parts. In other words, it is suitable for a single piece, small batch production and new product development, which shortens the production preparation cycle and saves a lot of process equipment costs.
processing conditions, using the same tool and processing program, the tool path is completely the same, the consistency of parts is good, and the quality is stable.
CNC machine tool processing can accurately estimate the processing time in advance, the use of tools, fixtures can be standardized, modern management. Numerical control machine tool uses digital signal and standard code as control information, which is easy to realize the standardization of machining information. At present, it has been organically combined with computer-aided design and manufacturing (CAD / CAM), which is the basis of modern integrated manufacturing technology.
After the adjustment of the CNC machine before processing, input the program and start, the machine can automatically and continuously process until the end of processing. The operator is mainly the program input, editing, loading and unloading parts, tool preparation, processing state observation, parts inspection and other work, the labor intensity is greatly reduced, the labor of the machine tool operator tends to be intelligent work. In addition, the machine tool is generally closed processing, which is clean and safe.
With the development of science and technology, numerical control technology plays a more and more important role in machining. The understanding of practical talents in enterprises has changed greatly. In addition to mastering certain professional skills, workers also need to have relevant knowledge of CNC milling technology.
