Bond characteristic of Diamond/CBN wheel

Resinoid Bonded Wheels

Resinoid bonded wheels are produced by bonding diamond and CBN grains with phenol resin.

Some of them are produced with filler to improve strength and/or heat-resisting property.

With selfgenerating cutting edges, resinoid bonded wheels have excellent cutting ability and longer dress interval. Thus, resinoid bonded wheels suit various uses such as tool grinding, quenched steel grinding, grinding of glasses, ceramics, ferrite that requires quality characteristic or strict surface roughness and high precision grinding..

BX Wheels/RX Wheels

BX wheels/RX wheels are produced by bonding diamond and CBN grains with polyimide resin to reinforce heat-resisting property of phenol resin wheel.
These wheels cut deep and feed slowly, and thus, are suitable for heavy grinding.

Vitrified Bonded Wheels

Vitrified bonded wheels are produced with high strength glass bond.
While other bonds are poreless, vitrified bonded wheels can be made porous.
Vitrified bonded CBN wheels are easy to dress unlike wheels of other bonds, and have excellent cutting ability. Therefore, are widely used in many grinding works.

Metal Bonded Wheels

Metal bonded wheels are produced by bonding grains with metal powders such as copper, tin, steel and cobalt. These wheels hold grains well and are highly abrasion resistant, impact resistant and long-life.

Electroplated Tools

Electroplated tools are produced by fixing grain with single layer nickel plating. With the excellent grain protrusion, they have excellent cutting ability and removal speed.
Since grains are fixed by plating method, forming wheels of complicated shape can be produced comparatively easily, given the steel core can be made.
