【Manufacturing Method】 Vitreous Method

It has many pores and is less prone to grinding burns! It is used in a wide range of fields from rough grinding to precision grinding.

The "Vitrified Bonding Method" involves adding inorganic materials such as feldspar and clay as a binder to the abrasive grains, mixing in an appropriate amount of auxiliary agents, kneading, molding, and firing at a high temperature of 1,300°C for production. These products have a high porosity, are less prone to grinding burns, and are used in a wide range of applications from coarse grinding (#20 and above) to precision grinding (up to #4000). Recently, grinding wheels with larger pores have been developed, expanding their application as grinding wheels that alleviate clogging during grinding. 【Features】 ■ Manufactured by firing at a high temperature of 1,300°C ■ High porosity, less prone to grinding burns ■ Used in a wide range of applications from coarse to precision grinding ■ Expanding applications as grinding wheels that alleviate clogging during grinding *For more details, please refer to the PDF document or feel free to contact us.

Thin Cutting Wheel "Sokuwaza"

This one piece, arrived at from the obsession with cutting! A thin cutting disc that slices through the metals of the world.

"Speed Technology" is a thin cutting wheel developed with the concept of making cutting operations faster and reducing heat generation. By blending a special abrasive (new ceramics abrasive), it achieves excellent cutting performance and durability. We have re-evaluated the entire manufacturing process and established a new production method. This results in reduced product costs and time costs, along with a superior and reliable design achieved through the new manufacturing method. [Features] - Blends a special abrasive (new ceramics abrasive) - Achieves excellent cutting performance and durability - Re-evaluated the entire manufacturing process and established a new production method - Reduces product costs and time costs - Superior and reliable design achieved through the new manufacturing method *For more details, please refer to the PDF document or feel free to contact us.

[Method Introduction] Resinoid Method

It is widely used for processes ranging from regrinding, roll grinding, cutting, deburring, and other precision finishing operations.

The "Resinoid Manufacturing Method" involves adding phenolic synthetic resin and other binding agents to the abrasive grains of the raw material, and then firing it at around 200°C to produce the product. The vitrified manufacturing method allows for the production of grinding wheels using ultra-fine powders that are difficult to use or abrasive grains that are challenging to combine, without deformation, resulting in grinding wheels with excellent grinding performance (sharpness and finish). Grinding wheels produced by this method are used for ultra-precision finishing processes, such as polishing grinding wheels for magnetic heads of audio and video card readers or ferrite cores, as well as for end face polishing of fiber optic connector parts, due to their good grinding performance. 【Features】 ■ Manufactured by firing at around 200°C ■ Capable of producing grinding wheels with good grinding performance ■ High safety due to elasticity and toughness ■ Widely used *For more details, please refer to the PDF document or feel free to contact us.

Yamabuki - High Grade Oil Stone -

Successfully developed high-precision grinding wheels that can be supplied at a low cost and with stable availability!!

Generally, there are few artificial grinding stones used for high-precision grinding in manual polishing work, and natural stones such as Arkansas stones are sometimes used. Natural stones are difficult to obtain, expensive, and in recent years, high-quality ones have become harder to find, with fewer imports. Therefore, our company has been working on the development of high-precision grinding stones that can be supplied at a low cost and in a stable manner. The new product "Yamabuki" uses tough alumina-based abrasive grains, has a particle size equivalent to #6000, and is a groundbreaking product that has wax impregnated into a vitrified bond stone that has been fired at high temperatures. (Note) Due to being a flammable solid, please ensure that the grinding stone is dried naturally. It may cause a fire.

Arkansas stone

Natural whetstone produced in Arkansas, United States, boasting world-class quality.

Arkansas stones are natural sharpening stones produced in the Ouachita Mountains of Arkansas, United States. This raw material is called novaculite, a sedimentary rock composed of microcrystalline quartz, recognized as a type of chert that has recrystallized, and it consists of over 99 percent pure silica. Novaculite is a sharpening stone that is almost nonexistent outside the Ouachita Mountains of Arkansas, making it the finest polishing stone in the world. **Grades of Arkansas Stones** Soft Arkansas Stone (medium grit, specific gravity 2.25–2.30) Hard Select Arkansas Stone (fine grit, specific gravity 2.30-2.45) True Hard Arkansas Stone (extra fine grit, specific gravity 2.5 or higher) Black Hard Arkansas Stone (extra fine grit, specific gravity 2.5 or higher) Translucent Hard Arkansas Stone (extra fine grit, specific gravity 2.5 or higher) Arkansas stones and novaculite are classified by specific gravity rather than grain size.
