Custom Honing Stones

Hongtuo is a specialist manufacturer of diamond and CBN honing stones with over 15 years of experience. Not only can we provide abrasive honing stones for Sunnen honing equipment, we can also offer custom honing stones for other brand name honing equipment, such as Hagel, Gerhing, Nissin and others.

Our self-developed honing and grinding stones can be used to hone open holes, blind holes, holes with keyways, stepped holes and more. When combined with other accessories, they can form a single stroke honing tool or multi-stone honing tool.

Customers can select from our honing stones or sticks without bases according to the type of bore to be finished. Basic sizes of the bore finishing stone are shown in the following picture.

**NOTE: Size LxWxH (length x width x height); When the width exceeds 6 mm, the stone needs to be slotted. (Code C)

Bore Types
  • Through Hole
  • Honing stone for through hole
  • Hole with Keyway
  • Honing stone for hole with keyway
  • Hole with Tandem Land
  • Honing stone for hole with tandem land
  • Blind Hole
  • Honing stone for blind hole

The length of the honing stone used for machining blind holes depends on the hole’s length. If the stone is too short, the honing efficiency will be reduced. If the stone is too long, the hole’s cylindrical degree will be affected.
