Mounted Points for Internal Grinding / JIG Grinding
Super Abrasive Mounted Points (CBN / Diamond)
We line up characteristic bonds (types) from the abundant bond system that we have been cultivating for many years.
The “VITBORA G-type,” which is superior in dressing ability and optimal for precision mass production internal grinding, has uniform vent holes for stable sharpness that lasts due to its high abrasive grain retention.
In addition, our unique “Metaceran” (registered trademark) features a mixed bond with vitrification and metal, which is high in heat-resistance and characteristically sees less loading / glazing than metal.
Bond type：
Vitrified, Electroplated, Metaceran, Resinoid, Metal
Stone outer diameter：
φ0.05～5mm (Tungsten carbide shank), φ0.3～15mm (stainless shank)
Standard inventory：
Over 300 types (Electroplated)
Application：
Ceramic parts for semiconductor manufacturing equipment
Automobile powertrain parts (parts for fuel injection pumps, steering parts)
Aspheric lens molds, bearings, precision gears.
Mounted Points for Precision Grinding
One of our company’s specialized fields. We respond to special orders regarding mounted points with specifications in many shapes and sizes for use in grinding that demands precise accuracy, especially for bearings, etc.
We have been making deliveries to major manufacturers of bearings in Japan for more than 30 years while receiving praise for our high reliability regarding quality.
Furthermore, we are capable of producing mounted point outer diameters with a dimensional accuracy of ±0.01mm; generally +0/-0.01mm （φ3〜6.35） for shank accuracy and +0/-0.005mm for high-accuracy parts.
Bond type：
Vitrified
Stone outer diameter：
φ0.8mm～ accuracy ±1/100mm
Shank diameter accuracy：
For a shank diameter of 3mm～6.35mm, +0/-0.01 (stainless), +0/-0.005mm (Tungsten carbide)
Application：
Bearings, miniature ball bearings
Mounted Points for Hand Grinders (Conventional Mounted Points)
We constantly maintain our position at #1 in market shares for mounted points in Japan, along with the plentiful assortment of products in our standard inventory. These are continuously used in turbine blades for aircraft engines, and the maintenance of turbine blades for major heavy industry power generators. Furthermore, they are used in turbochargers for automobiles.
