4, There are many different kinds of machining process we can do:
5,Test the quality according to cusdifferent requirements
Straight the linear shaft straightness:
We control the traighness 0.05mm of linear shaft 300mm
Test hardness:
S45C materail induction linear shaft, the hardness is HRC55-58
GCr15 (SUJ2) materail induction linear shaft, the hardness is HRC58-63
If flexible shaft, the hardness is based on the shaft material itself
Test linear shaft surface roughness
the max roughness is Ra0.4um
