ID Honing


Utilize an abrasive stone,which turns while being moved in and out of the work piece.

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 

Roller Burnish+ Skiving

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  .
