The BASIC PROCESS
Fristly,hardness of the workpiece's surface can reach to HRC55-58 at the highest with machanical rough maching to heat treatment.
Secondly,the hardness of the surface can reach to HRC62 with the processing of machanical finish turning,grinding and hard chrome palting.
Lastly,the highest finish can reach to Ra0.01umm(level 14)and the thermal deformation doesn't exceed 0.01mm after the process of finish grinding,pre-polished,precision polishing and intermediate conduction oil heating.
