Basic knowledge of the application and characteristics of CNC lathe processing

- 2021-12-13-

CNC numerical control lathe processing has been increasingly used in modern manufacturing, and it has exerted its incomparable advantages over ordinary lathes. 

CNC numerical control lathe processing mainly has the following points.

1. The transmission chain of CNC lathe processing is short. Compared with ordinary lathes, the main shaft drive is no longer the change of the motor belt gear mechanism, but the transverse and longitudinal feeds are driven by two servo motors respectively, and are no longer used. The transmission chain is greatly shortened for traditional parts such as change wheels and clutches.

2. High rigidity, in order to match the high precision of the numerical control system, the rigidity of CNC numerical control lathe processing is high, so as to meet the high precision processing requirements.

3. Lightly drag, the tool post (worktable) is moved by ball screw pair, with low friction and light movement. The supporting special bearings at both ends of the screw have a larger pressure angle than ordinary bearings and are selected when leaving the factory; the lubrication part of the CNC lathe is automatically lubricated with oil mist. These measures make the CNC lathe processing easier to move.

 CNC lathe processing features

1. High degree of automation can reduce the operator's physical labor intensity. The CNC lathe machining process is automatically completed according to the input program. The operator only needs to start tool setting, load and unload the workpiece, and change the tool. During the machining process, the main task is to observe and supervise the operation of the lathe. However, due to the high technical content of CNC lathes, the operator's mental work is correspondingly improved.

2. CNC lathe processing parts have high precision and stable quality. The positioning accuracy and repeat positioning accuracy of CNC lathes are very high, and it is easier to ensure the consistency of a batch of parts. As long as the process design and procedures are correct and reasonable, coupled with careful operation, the parts can be guaranteed to obtain high machining accuracy and easy to align. The CNC lathe processing process implements quality control.

3. The processing efficiency of CNC lathes is improved. CNC lathe processing is able to process multiple processing surfaces in clamping once again. Generally, only the first part is inspected. Therefore, many intermediate processes in ordinary lathe processing, such as scribing, size inspection, etc., can be omitted, which reduces the auxiliary time. Moreover, because the quality of the parts processed by the CNC lathe is stable, it brings convenience to the subsequent process, and its overall efficiency is significantly improved.

4. CNC lathe processing is convenient for new product development and modification. CNC lathe processing generally does not require a lot of complicated process equipment, and the parts with complex shapes and high precision requirements can be processed by programming the processing program. When the product is remodeled or the design is changed, only the program is changed, without the need to redesign. Tooling. Therefore, CNC numerical control lathe processing can greatly shorten the product development cycle, and provide a shortcut for the research and development of new products, product improvement, and modification.

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

6. The initial investment in CNC lathe processing is relatively large. This is due to factors such as high cost of CNC lathe processing equipment, long preparation period for the first processing, and high maintenance costs.

7. CNC lathe processing and maintenance requirements are high. CNC lathe is a typical CNC lathe processing product of technology-intensive mechatronics. It requires maintenance personnel to understand both mechanical and microelectronics maintenance knowledge, and at the same time, it must be equipped with better maintenance equipment.
