What is the tolerance of China metal parts manufacturing?

The tolerance of China metal parts manufacturing is 0.05mm. The tolerance can be customized according to different customers’ requirements.

Tolerance is a deviation in size or shape from the nominal size, which is standard in the industry. For example, if the diameter of a hole is specified at 1mm and its actual dimension is 0.955mm, then it has a tolerance of 0.045mm. If the tolerance is too high, it will cause problems such as excessive friction during assembly and poor accuracy. If the tolerance is too high, it will cause problems such as excessive friction during assembly and poor accuracy. The tolerance should be determined based on the application requirements of each component and component assembly process requirements.
