Cylinder Block Machining

H-E Parts goes unmatched in terms of ability and technology. Utilizing state of the art equipment, along with close attention to detail makes our block department one of the most dynamic in the world. OEM engine designers often utilize our expertise and technology when developing repair strategies for their products. Boring repeatability is within .0001”. CBN cutting technology controls surface finish and heat distortion as the heat is eliminated from the component with the chip load. This gives us the ability to be highly accurate for both size and surface finish.

Cylinder blocks must pass a 95-point inspection. All critical cylinder block areas are Portaflux inspected. Machining is accomplished in one of our controlled work stations with .0001” (0.00254  mm) Machining is accomplished using the latest cutting technology, eliminating the possibility of heat distortion while re-establishing critical surface finishes.
