machining tolerance for grinding

Guide to CNC Machining Tolerances Fractory

2020-11-10  For CNC machining, the standard tolerance limit is set around +/-.005” (0.127 mm). For reference, the thickness of a human hair is 0.002” (0.05 mm). The standard tolerance limit is a small number and in most cases, such a small difference between two parts that perform the same function may not even matter.

Tolerance Grade for Different Machining Process

The machining accuracy of milling is generally up to IT8~IT7, and the surface roughness is 6.3~1.6μm. 1) The machining accuracy during rough milling is IT11~IT13, and the surface roughness is 5~20μm. 2) The machining precision during semi-finishing milling is IT8~IT11, and the surface roughness is 2.5~10μm.
