Methods to improve the surface quality of turning machining parts

Methods to improve the surface quality of turning Machining Parts:

1. Reduce the height of residual area. The height of the residual area can be reduced by reducing the main deflection angle, the secondary deflection angle, the feed rate and increasing the radius of the tool tip arc

2. Avoid the generation of swarf and prick marks. The method of changing cutting speed can be used to restrain the formation of chip accretion.

3. Avoid wear and bright spots. When the workpiece is turned, bright spots or bright spots appear on the machined surface, and there is noise when cutting, which indicates that the tool has been seriously worn.

The blunt cutting edge will extrude bright marks on the surface of the workpiece, so that the surface roughness becomes larger. At this time, it is necessary to regrind or change the tool in time.

4. Prevent chips from roughening the machined surface. Chips will have irregular shallow scratches on the machined surface. Therefore, it is necessary to select the turning tool with positive blade angle to make the chips flow to the surface to be machined, and take appropriate measures to break the chips.

5. Prevent and eliminate vibration marks, select cutting oil reasonably, and ensure adequate cooling and lubrication.
