The accuracy of scale is still the roughness accuracy, and the accuracy of form and position service level. The dimension accuracy of the machine tool can be controlled by 0.01mm, and the roughness can reach 1.6. For the shape and position service, such as coaxiality, concentricity, runout and straightness. Flatness, perpendicularity can ensure the following range;
The accuracy of outer circle is 0.01
Cylindricity 0.01/100
Flatness of end face 0.02/200
The accuracy of thread pitch is 0.06/300
Generally, the precision of machining mainly refers to four points
- Scale public service
- Public service of shape
- Public service of bearing degree
- Surface finish (as for the other largest solid scale flows, this is a concept that has only recently emerged.
You didn’t say that the ordinary lathe is a CNC lathe, which means the highest machining accuracy of the ordinary lathe. The CNC precision is higher, but this one is not certain. For example, the cylindrical cylinder service is 0.01-0.02MM. General lathe can also reach.
In addition to the accuracy of the outer circle, but also to see the requirements of the drawing requirements of the surface finish, for example, the cylindrical service 0.01-0.02 mm, finish in 1.6-3.2, then you can choose general lathe or CNC lathe, but the finish in 0.8 may be higher, then you can not choose a lathe, the choice of grinding machine processing.
In the case of CNC milling machine tool, sometimes you need to consider the machining center of the lathe, if you have higher requirements for the lathe perpendicularity, you may need to consider the machining center of the lathe.
General good point lathe turning processing can be up to 6 grade public service belt products.
Misunderstanding of high machining accuracy of CNC machine tools:
Generally, the precision of machining mainly refers to four points
- Scale public service
- Public service of shape
- Public service of bearing degree
- Surface finish (as for the other largest solid scale flows, this is a concept that has only recently emerged.
