For the high quality bearing production, except for the high precision bearing machineries, tools and gauge applied in the machineries are playing especially roles. HCH never compromises on the quality of tools and gauge. All HCH grinding wheels and super finish stones that are imported from Japan could process the high precision bearing grinding and super finishing to provide stable high quality bearings with excellent bearing roughness, roundness and waviness etc. HCH believes that efficient tools management increases the productivity and reduce the cost. We have a qualified engineers team that provides a good resource for tool and gauge design, fabrication and verification activities. HCH has been building top quality tool management system since 1980. HCH has established an vertical tool management system as following:
