ID Honing
The honing process makes :
1.Smooth surface finishes inside bores
2.Hold precise tolerances on bore diameters
ID H7 H8 H9
ID roughness 0.2-0.8μm
ID max 630mm
Two thin chips are cut at high feed rate while the tool passes through the workpiece.producing super finish surface,with a bore precise tolerance .
