Processing Of Thin-walled Parts Of CNC Lathe（1）

1. Analysis of the factors affecting the precision of thin-walled parts during CNC machining. The important feature of thin-walled parts is lightness. It is one of the difficulties in the processing and production process to ensure the processing accuracy of thin-walled parts. To ensure that no deformation, In case of scrapping, it is necessary to strictly control the processing technology and strictly control the calculation accuracy during the processing.

For the processing of thin-walled parts, it is necessary to ensure its accuracy and avoid heat deformation of the parts during the processing. Under normal circumstances, parts with thin outer walls will deform during processing even when they are heated, which will lead to poor parts accuracy and do not meet quality standards. In addition, after the clamping of thin-walled parts is completed, during the roughing and finishing process , Can not avoid heating, as a result, there will be problems such as parts deformation.

The material of thin-walled parts is generally lighter and thinner. Under external pressure, it will deform, causing changes in thin-walled parts to varying degrees. Generally speaking, thin-walled parts are affected by radial cutting forces during the machining process, and vibration will occur, which will have a certain effect on the appearance of the parts and the roughness of the surface. During the processing of thin-walled parts, the blade The main declination angle generally determines the radial cutting force and the distribution angle of the part. For thin-walled parts, its rigidity is poor, and the angle of the tool will directly cause the unevenness of the surface roughness of the part.
