42CrMoS4 turned ground and polished steel round bar

42CrMoS4 turned ground and polished steel round bar   42CrMoS4 ground and polished steel bar is a kind of machining used to remove the imperfections on the hot rolled bars surface such as the scales and the decarbornization. It can also get more precision diameter tolerance and bright surface after peeling or turning. If grinding or polishing is added, the steel bars will be have very good surface roughness and straightness which can be directly used to produce components. 42CrMoS4 turned, ground and polished precision shafting is produce by 42CrMoS4 cold drawn or hot roll steel bar to get precision dimension and better straightness in the production of shafts. The straightness is quite important to shafting CNC machining. 42CrMoS4 turned ground and polished steel bar is used to produce crankshafts, high-speed motor shafts, axle shafts, pup shafts, etc.   42CrMoS4 turned ground…
