CBN Diamond Honing Stone Cylinder Block Crankpin Industrial With
Custome Size
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)
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.
