CNC lathe is the abbreviation of digital control lathe, which is an automatic lathe equipped with a program control system. The control system can use control code or other symbolic instructions to logically process and decode the program, express it with coded numbers, and input it into the numerical control device through the information carrier.

Because of its high accuracy, high efficiency, adaptability to small batch and multiple varieties of complex parts processing, CNC lathe has been widely used in mechanical processing, and has achieved good economic benefits in the batch production of complex parts. Compared with the traditional lathe industry, CNC lathe has the following characteristics:

1. Strong adaptability

When machining a new workpiece, the CNC lathe only needs to reprogram the processing program of the new workpiece to realize the processing of the new workpiece. It does not need to make a batch of tooling fixtures, nor does it need to repeatedly adjust the lathe. Therefore, it is particularly suitable for processing single piece, small batch and trial production of new products. For the precise and complex parts that are difficult to be processed by ordinary lathes, CNC lathes can also realize automatic processing.


2. High machining accuracy

CNC lathe can achieve high machining accuracy by processing according to digital instructions. At present, the machining positioning accuracy of CNC lathes is generally as high as 0.03MM, and the repeated positioning accuracy is 0.01MM. Some high-end CNC lathe manufacturers can even be accurate to 0.003MM. In addition, the transmission system and lathe structure of the CNC lathe have high rigidity and thermal stability, high manufacturing accuracy, and the automatic processing mode of the CNC lathe avoids human interference factors. The size consistency of parts in the same batch is good, the product qualification rate is high, and the processing quality is very stable.


3. High production efficiency

The adjustment range of main oil speed and feed speed of CNC lathe is larger than that of ordinary lathe, so the most favorable cutting parameters can be selected for each process of CNC lathe. Acceleration and deceleration measures are adopted from fast moving to stopping, which not only improves the moving speed, but also ensures the positioning accuracy and effectively reduces the maneuvering time.


4. It is conducive to the automation of production management

CNC lathes can accurately calculate the individual working hours of products, reasonably arrange production, use digital information and standard code to process and control processing, effectively simplify the information transfer between inspection, fixture and semi-finished products, and create necessary conditions for the automation of production process.

Lathe industry is the basic industry of manufacturing industry and also the pillar industry to promote the development of national economy. China's lathe industry developed late. In recent years, with the support of relevant national plans, China has made some breakthroughs in the key technology and research of CNC lathes by continuously introducing advanced foreign technologies and equipment, absorbing the design and management concepts of foreign products. High-tech enterprises with independent intellectual property rights and core technologies are building a domestic CNC system industry with core competitiveness through their own efforts and technological innovation.
