Tight Machining tolerance

Machining tolerance means the dimension range that can be meet by CNC Machining, Machining tolerances may be affected by a number of factors. such as fixture design & produce, raw material, machining equipment & cutters, inspection equipment, and workers skill. The machining tolerance are vary from factory to factory. Some factory may be specialized in small aluminum parts, and others could be more professional in larger stainless steel parts.

Generally, Machining tolerances can be devide into Linear Tolerances and Geometric Tolerances. If not specified, We follow ISO 2768 standard to produce the machined parts, we can reach ISO2768-mk & ISO2768-f standard.

Precision CNC Turning Tolerance:

Linear tolerance: Machining tolerance grade: IT 6-7

Flatness:Machining tolerance grade: IT 5-6

straightness: Machining tolerance grade: IT 5-6

Cylindricity:Machining tolerance grade: IT 5-6

Surface roughness:  For Turning process, we can reach Ra 0.8- 3.2 for metal material, Ra 0.4-1.6 for plastic material. For facing process, we can reach Ra1.6-6.3 for metal material and Ra 0.2-0.8 for plastic. For Boring process, We can reach Ra 0.4-0.8 for metal and Ra0.2-0.4 For plastic.
