Product List

A single wheel of this type can perform multiple grinding processes such as rough grinding, pre-finishing, and finishing. This allows multiple processes to be performed with a single machine without replacing tools, which reduces processing time. Multi-layer wheels with a combination of metal bonds for rough grinding, resin bonds for pre-finishing, and resin bonds for finishing are available.

Diamond metal bond wheels with spindle are specially designed for machining hard and brittle materials.
We offer the most suitable bond specifications for various materials in the grinding process of hard and brittle materials using a machining/gliding center.
The metal bond wheel has high abrasive grain retention and high sharpness even when machining hard materials. It also has good thermal conductivity, which prevents heat buildup at the machining point and prevents thermal cracking of brittle materials. The tool life is longer than that of electrodeposition tools with a single diamond layer, and it is the best tool for machining ceramics, especially hard SiC and aluminum nitride.
In the machining of quartz glass, the optimum bond selection ensures high grinding durability.

These wheels are used for the internal grinding of precision parts and precision machining of glass, ceramics, carbon, ferrite, and precious stones. We provide wheels with the most suitable bond and specifications for the work material and application.

Metal bonds are ideal for machining hard and brittle materials. It is especially suitable for machining fine ceramics such as silicon carbide (SiC), aluminum nitride (AlN), silicon nitride (SiN), and quartz glass.

The electrodeposition bond has good sharpness and versatility, and can be used not only for hard and brittle materials but also for carbon, ferrite, MMC materials, FRP, and cemented carbide.

Resin bond is used for the purpose of reducing damage such as chipping of the workpiece and for finishing processes that require surface roughness.

It is also possible to manufacture wheels with spindles with an outer diameter of φ100 or larger by joining a straight wheel or cup wheel to the spindle. Please consult with us for such products.

The "MF50" metal bond wheel is used for fine ceramics forming, glass substrate chamfering, and the forming of other hard brittle materials. Its advantages include high cutting performance and low grinding noise.

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.

This chamfering wheel is designed to maintain substrate strength when fabricating glass display panels and cover glasses. Wheels for facilitating high-speed substrate feeding are available for various machines.

High-quality finishing is realized by electroplating fine abrasive grains of around #1000～#2000.
■ High-quality finishing is realized with good surface roughness and less tipping.
■ High ability of maintaining the wheel shape realizes high-precision shape forming.
■ Multi-layered electroplating can be conducted to extend the life of the wheel.

These wheels are used to chamfer the inner diameter (ID) or outer diameter (OD) edge of glass disks. Due to the special electroplating used in this design, the roughness of chamfered surfaces are improved and chipping at the boundary area to the edge surface is minimized. Wheels using micron size abrasive grain are available.

■Realizing persistence of the grinding performance of the diamond abrasive grains and longer tool life.
■The long tool life stabilizes the processing quality.

These wheels are designed for high shape precision forming of, for example, motor cores. Wheels of the most appropriate specifications are available for not only magnetic materials such as neodymium-iron, but also for ferrites, ceramics and glass.
