Vitrified bond which is retentive and chemically stable is suitable for grinding hard-to-grind materials and high efficiency and precision grinding.
It is difficult to manufacture vitrified wheels, but we can manufacture vitrified wheels with a variety of characters through long time study.

The TDX wheel is a new VIT Diamond wheel that uses new abrasive materials that are tough and long-lasting, and new bonds that are powerful and sharp. In addition, because it was changed to a manufacturing method that minimizes damage to the diamond due to heat, it is suitable for processing that makes use of the original sharpness of the diamond. As with conventional VIT wheels, features such as high rigidity, low thermal expansion, and pores due to integrated molding remain unchanged, so it can be replaced with conventional products.

Synergy wheel is resinoid type wheels(dia/cBN) has a ceramics core.
This wheel has high grinding performance than the resinoid type and vitrified type has a metal core. This wheel decreases dimension error from temperature change and reduce grinding noise.

User can choose product to suit their condition such as dresser, grinding machine and grinding method.Furthermore we provide suitable wheels to meet user’s grinding condition.

​It has good chip removal and porosity performance comparable to that of a PT grinding wheel, which suppresses heat generation, and the structure of a general grinding wheel, which has excellent metal workability. ​It is ideal for machining stainless steel, copper, aluminum, and other materials that are sticky and change greatly when heated. It is also often used for machining the magnetic tables of surface grinders. ​

RZ is a high-performance grinding wheel that uses micro-structured polycrystalline composite abrasive grains composed of non-melting alumina ceramic. Sub-micron fine crushing has resulted in a grinding wheel that cuts with little wear.

The performance difference is 2 to 6 times that of conventional WA wheels, which leads to a significant reduction in processing time. It also has excellent cost performance because it is less likely to clog and maintains its cutting power even when the diameter is small. It can also be easily molded, which is difficult with CBN wheels. Depending on the grinding conditions, you can choose from five types: RZ, RZW, RZi, RZS, and RZ Dolce. By using it together with the dedicated RZ dresser, you can expect even greater effects.

The key to machining workpieces with low melting points is to minimize the generation of grinding heat.
1) The process requires removing a large amount of chips from the workpiece.
2) The chips must not get into the pores of the grinding wheel. To satisfy these conditions, numerous and large pores are required. PT grinding wheels make it possible to freely control the size and amount of these pores and to design and manufacture them.

Mixing WA and GC is not easy because they have different characteristics, including thermal expansion coefficients. However, the newly developed V29 bond has succeeded in solving these problems.
Depending on the workpiece and content, you can choose from three types of abrasives: HW, HWP, and HWR.
The main uses are as follows:
HW: For thin material processing
HWP: Mainly for casting processing
HWR: All-purpose processing

This giant pore grinding wheel is an evolution of Teiken’s long-selling PT grinding wheel. The pore diameter is up to 6 mm, and by combining it with small pores, the porosity is also improved. It is extremely effective for workpieces that are sensitive to heat, such as rubber, urethane, and resin, as well as for machining that generates large amounts of cutting chips and machining that is prone to clogging.

Alumina abrasive grains are used for grinding steel-based hardened materials.
Common abrasives include A, WA, PA, and HA. Although they are all called alumina abrasive grains, they have a variety of properties such as polycrystalline and single crystal crystal structures, and blocky and friable grain shapes.
However, while each has its own unique characteristics, they are not perfect. SPW has achieved excellent performance by taking advantage of the characteristics of each and compensating for its weak points. In addition, since it is not an expensive ceramic abrasive grain, it is also effective in reducing costs.

The Dolce series is a new grinding wheel that combines a new bond that acts softly with pores of the optimal size and amount for high-hardness metal workpieces. In addition to high-hardness workpieces, it is also effective for thin material processing and low-rigidity workpieces. The grinding sound is light and soft, and there is little heat generated, making it possible to set a finer grain size than before, making it an evolved grinding wheel suitable for high-precision processing.
