Product List

These metal bond wheels are designed with a new concept, and have both the high cutting performance of resin bonds and the abrasion resistance of metal bonds. They are suitable for efficient grinding of difficult-to-cut materials such as Al2O3-TiC and quartz.

This wheels is used for forming / grooving of fine ceramics, quartz and other hard brittle materials and high-speed steel, and chamfering of glass substrates.

The "MB" bond series is a resin bond wheel with high shape retention using heat-resistant resin and metal filler. It has high sharpness and high shape retention in heavy-duty grinding with a large depth of cut.
The ability to form by electrical discharge machining makes it possible to form differently shaped abrasive grain layers, which are usually difficult to form, making this bond very suitable for machining with formed tools in plunge grinding.


The "MB" bond series is a bond that works well with both diamond and CBN wheels.
The diamond wheels are suitable for machining with formed tools for quartz, ceramics, and cemented carbides.
CBN wheels are suitable for the machining of high-speed steel blades and for machining with formed tools for iron-based machine parts that require high accuracy.
Since the wheels are heat resistant and capable of heavy-duty grinding, we have experience in machining with formed tools using multi-wheels that combine several wheels.

By using the metal bond having significantly higher heat conduction than a vitrified bond, the influence of heat on the working surface is minimized.
■ The product not only maintains cutting performance and realizes long tool life, but also suppresses burning of work materials.
■ Since it can suppress heat stress on work materials more than conventional abrasive wheels, reduction of the fatigue-resistant strength of the work can be suppressed.
■ Little damage on abrasive grains and appropriate spontaneous blade generation can realize long dress intervals and reduce down time.

 

[Target materials for CBN metal bond wheels]

- HSS (High-Speed Steel)
- Hardened Steel (carbon steel, die steel)

These wheels realize high-precision grinding of iron materials used for automobile parts and the like. They provide the advantages of high performance and stable quality. CBN wheels with an axis are also available.

These wheels demonstrate their distinguished performance for deep-gutter flute grinding of cemented carbide / tungsten carbide tools. Compared to conventional resin bond wheels, they reduce machining time and abrasion. They also achieve stable cutting performance, high-precision, and high-quality surface roughness, and reduce the generation of chips. "BI30" and "MB" series resin bond wheels are also available depending on the materials to be ground and on usage.

These wheels are used for grinding PCD and PCBN tools, which have higher hardness, higher strength and higher abrasion resistance than carbide tools. Two (non-porous and porous) "high-RESPONSE" bond types are available to meet customer needs for higher precision and higher efficiency.

The highly durable "BJ0" resin bond wheel is useful for flute grinding of high-speed drills and taps. It has low grinding resistance in creep feed grinding of high-speed steel, thus maintaining its high cutting performance.

These products employ PCD (polycrystalline diamond), which is usually used to fabricate wear resistant parts for cylindrical grinding of ceramics and cemented carbide / tungsten carbide materials. Concave and convex centers of various sizes are available for various uses.
