What level of accuracy can a lathe achieve？

Scale accuracy is still roughness accuracy is still form position service grade accuracy, machine tool factory scale accuracy can control 0.01mm, about roughness up to 1.6, about form position service such as coaxiality, concentricity, beat, straightness. Flatness, perpendicularity can ensure the following range;

Accuracy of outer circle is 0.01

Cylindrical cylindricity 0.01/100

The flatness of the end face is 0.02/200

Thread pitch accuracy 0.06/300

Usually, machining precision refers to four points:

1. Scale of public service

2. Shape degree public service

3, Azimuth degree public service

4, surface finish (as for the other largest physical scale of the stream is actually a recent concept.

You did not say that the car is CNC car above the highest machining precision, CNC precision is higher, but this is not sure, such as the outer circle of the public service 0.01-0.02mm.General lathe also can arrive.

In addition to the precision scale of the outer circle, but also to see the requirements of the drawing requirements of the outer circle, for example, the outer circle service 0.01--0.02mm, smoothness in 1.6-3.2, then you can choose the general lathe or CNC lathe, but smoothness in 0.8 May be higher, so you can not choose the lathe, the selection of the grinder processing.

Sometimes drawings require the size of the civil service between 0.01-0.05, you can choose the lathe, CNC, milling machine, machining center, but if the coaxiality, perpendicularity, parallelism, higher requirements, you need to consider the grinder processing may be other machine tools.

Generally good point lathe turning processing can do up to 6 grade of service belt products.

Misunderstanding of high machining accuracy of nc machine tools:

Usually, machining precision refers to four points:

1. Scale of public service

2. Shape degree public service

3, azimuth degree public service

4, surface finish (as for the other largest physical scale of the stream is actually a recent concept.
