Why are CNC lathes so popular

Why are CNC lathes so popular

06-01-2023

CNC lathes have been used more and more in modern manufacturing industry, giving play to the incomparable advantages of ordinary lathes. 

CNC lathe has the following characteristics:

1. The drive chain is short. Compared with the ordinary lathe, the spindle drive is no longer the speed change of the motor belt gear pair mechanism, but the transverse and longitudinal feed is driven by two servo motors. The traditional speed change gears and clutches are no longer used, so the drive chain is greatly shortened.

2. High rigidity. In order to match the high precision of CNC system, CNC lathe has high rigidity, so as to meet the requirements of high precision machining.

3. Lightly drag, the tool rest (workbench) moves with the ball screw pair, with small friction and convenient movement. The pressure angle of the special support bearing at both ends of the screw is larger than that of the ordinary bearing. The lubrication part of CNC lathe adopts oil mist automatic lubrication. These measures make the movement of CNC lathe convenient.

What are the characteristics of CNC lathe processing?

1. High degree of automation can reduce the physical labor intensity of operators. The CNC machining process is automatically completed according to the input program. The operator only needs to start tool setting, load and unload the workpiece, and replace the tool. During the processing, they mainly observe and supervise the operation of the lathe. However, due to the high technical content of CNC lathe, the mental labor of operators is also improved accordingly.

2. The processed parts have high precision and stable quality. The positioning accuracy and repeated positioning accuracy of the CNC lathe are very high, which can easily ensure the consistency of the size of a batch of parts. As long as the process design and program are correct and reasonable, combined with careful operation, the parts can obtain high processing accuracy, and also facilitate the quality control of the processing process.

3. High production efficiency. CNC lathe processing can process multiple machining surfaces in one clamping, so it can be used for many intermediate processes of ordinary lathes in various regions, such as scribing, size detection, etc. Reduced auxiliary time. Moreover, due to the stable quality of the parts processed by CNC, it brings convenience to the subsequent processing, and its overall efficiency is significantly improved.

4. Promote the development and modification of new products. NC lathe processing generally does not require many complex process equipment, and parts with complex shape and high accuracy requirements can be processed by programming. When the product is modified and the design is changed, only the program needs to be modified, and the tooling does not need to be redesigned. Therefore, CNC machining can greatly shorten the product development cycle and provide a shortcut for new product development, product improvement and modification.

5. It can be developed into a more advanced manufacturing system. CNC lathe and its processing technology are the basis of computer aided manufacturing.

6. Large initial investment. This is due to the high cost of CNC lathes, long preparation period for first processing and high maintenance costs.

7. High maintenance requirements. CNC lathe is a typical product of technology intensive electromechanical integration, which requires maintenance personnel to understand not only machinery, but also microelectronics maintenance, and better maintenance equipment.
