What level of accuracy can lathe processing reach?

The scale accuracy is still the roughness accuracy or the shape and position accuracy. The machine tool can control the scale accuracy of 0.01mm, and the roughness can reach 1.6. About the shape and position, such as coaxiality, concentricity, runout, and straightness . The flatness and perpendicularity can ensure the range as follows;

　　 Outer circle accuracy 0.01

　　 Cylindricity of outer circle 0.01/100

　　 End face flatness 0.02/200

　　 Thread pitch accuracy 0.06/300

　　 Generally, the accuracy of machining refers to four points:

　　1, standard public service

　　2, shape degree public service

　　3, azimuth public service

 cnc processing

　　4. Surface finish (As for the other largest physical scales, it is a concept that has only appeared in recent years.

　　 You did not say that the general car is a CNC car. The above refers to the highest machining accuracy of the general car. The CNC precision is higher, but this is not certain, such as the 0.01-0.02mm of the outer circle. Generally it can be reached by lathe.

In addition to the accuracy scale of the outer circle, you also need to see the requirements of the outer circle finish required by the drawing. For example, the outer circle service is 0.01-0.02mm and the finish is 1.6-3.2. Then you can choose a general lathe or a CNC lathe. But the finish may be higher at 0.8, so you can't choose a lathe, you should choose a grinder for processing.

Sometimes the drawings require the standard service to be between 0.01-0.05, you can choose lathe, CNC, milling machine, machining center, but if you have higher requirements for coaxiality, perpendicularity, and parallelism, you should consider The grinding machine may be other machine tools.

　　 Generally better lathe turning processing can be used for up to 6-level service belt products.

　　The misunderstanding of the high precision of CNC machine tools:

　　 Generally, the accuracy of machining refers to four points:

　　1, standard public service

　　2, shape degree public service

　　3, azimuth public service

　　4. Surface finish (As for the other largest physical scales, it is a concept that has only appeared in recent years.
