What are the common turning processing defects?

Ningbo Leke precision Technology is focus on precision turning parts and cnc milling parts, today we would like to talk about something about the turning process defects,hope can help you.

1. dimensional error : the size of the machined part does not meet the design requirements, which may be due to insufficient precision of the machine tool, tool wear, measurement errors and other reasons.

2. Shape error : such as cylindricity, roundness, straightness, etc. do not meet the standard, which may be caused by the wear of the machine tool guideway, improper workpiece clamping, uneven tool wear.

3. poor surface roughness: the turning surface appears rough, not polished, the reason may be tool edge is not sharp, cutting parameters are not reasonable, machine vibration.

4. vibration ripples: periodic ripples appear on the machined surface, usually due to insufficient rigidity of the machine tool, the cutting process is not stable, the workpiece or tool clamping is not solid, etc..

5. burn: the surface appears overheating discoloration or even burn marks, which is often due to too high a cutting speed, too small a feed, insufficient cooling and so on.

6. tool chipping: the tool is suddenly damaged in the cutting process, which may be due to excessive cutting force, inappropriate tool material, improper cutting parameters, etc.

7. Residual stress: Internal stresses generated during turning process may lead to deformation of the parts in subsequent use.

8. Thread defects: such as inaccurate thread tooth shape, pitch error, poor thread surface roughness, etc., which may be related to the tool, machine tool accuracy, machining parameters, etc.
