How many levels of precision can a lathe machining reach?

1. Regarding roughness up to 1.6

About shape and position official service such as coaxiality, concentricity, runout, straightness. Flatness and verticality can ensure the following ranges; Outer circle accuracy 0.01 Outer cylindricality 0.01 / 100 Face flatness 0.02 / 200 Thread pitch accuracy 0.06 / 300

2. Generally, the precision in mechanical machining refers to four points:

• 1.Scale public service
• 2.Shape degree public service
• 3.Azimuth official service

3. Surface finish (As for the flow of other largest physical scales, it is a concept that has only recently emerged. You did not say that the ordinary car is the highest machining accuracy of the ordinary car on the CNC car. The cnc machining accuracy is higher, but this is not certain, such as the external cylindrical service 0.01-0.02mm. Usually can be reached by lathes. In addition to the accuracy scale of the external circle, it also depends on the requirements of the external surface finish of the drawing. But the finish may be higher at 0.8, so you can't choose a lathe, you should choose a grinder. Sometimes the drawings require the scale to be in the range of 0.01-0.05. You can choose lathes, CNCs, milling machines, machining centers, but if you have higher requirements for coaxiality, perpendicularity, parallelism, you must consider Grinding may be another machine. Generally, the better lathe turning machining can be the highest grade 6 public service belt products.
