How many levels of precision can the lathe process?

Edit: Administrator Browse: Time: 2019-09-20

The precision of scale is still the precision of roughness and grade of the official service level. The machine tool factory can control the scale precision of 0.01mm, the roughness can reach 1.6, and the coaxiality and concentricity of the figure of official service, Beat, straightness. Flatness and verticality can ensure the range as follows:
External precision 0.01
Outer cylindricality 0.01 / 100
Flatness of end face
Screw buckle pitch precision 0.06 / 300
Generally, the precision of machining refers to four points:

1, scale public service 2, style public service 3, azimuth public service, cnc processing 4, appearance roughness (as for the flow of other largest physical scales, it is a concept that has only emerged in recent years.

You did not say that the ordinary car is a digitally controlled car, which means that the ordinary car has superior processing precision, and the digital control precision is higher, but there is no certainty, such as the external circular service 0.01-0.02mm. It can also be reached by ordinary lathes.
In addition to the precision scale of the outer circle, it is also necessary to look at the requirements for the roughness of the outer circle in the drawings. Digitally controlled lathes, but the roughness may be higher at 0.8, then you must not choose a lathe, it is time to choose a grinding machine.
Sometimes the drawings require the scale of public service to be between 0.01-0.05. You can choose lathes, digital controls, planers, and processing cores, but if you also have high requirements for coaxiality, straightness, and parallelism, you will It is necessary to consider the grinder machining and maybe other machine tools.
Ordinary better lathe turning processing can be used as a grade 6 public service belt product.
