Shaped Abrasive Stone
As a pioneer in the barrel finishing industry, we have developed superior finishing media based on our rich experience and outstanding technology over the years.
With our wide selection of materials, shapes, and sizes, you can freely select products that meet your finishing objectives.
Type Applications
GX Severe deburring Ideal for heavy cutting such as cutting streak.
G Excellent abrasion resistance, suitable for centrifugal barrel.
GV Appropriate for deburring and cutting.
CX Mild deburring. Ideal for soft metals. For medium cutting.
C For smooth finishing, glossy finishing, and glazing.
Special L With light specific gravity, performs gloss finishing while fine cutting.
L Being very hard, it hits the surface to give a glossy finish.

Lump Abrasive Stone
With the main component of this irregular-shaped polishing grit being a dissolving acidic alumina, tasks from heavy grinding to glossy finishing can be done, depending on how it’s used.
The product is economical due to the hard, tough texture that slows the consumption rate .

Clymax Compound
Crymax Compound has an important role of improving the quality of the polished products and shorten the polishing time by scientifically enhancing the physical finishing effect of crysteine media. Select from the following Clymax Compounds types that optimally match your parts materials and finishing objectives.
Basic elements of Crymax Compound
Has a softening effect on hard water, significantly increasing the efficiency of the finish.
A tough foam generated by dissolving fine particles in water mitigates the impact of the media on the components.
Cleans the surfaces of the part and media, thereby improving the polishing effect.
Has the role of preventing erosion during the polishing work or thereafter during the sorting.

Other media
We carry copper shots (TTP balls), steel shots, dry-type media, and other polishing materials.

Copper shots (TTP balls)
These shots used in the TTP polishing method are nearly 100% copper.
We carry the following range of ball sizes needed for polishing various part shapes and sizes.
TTP is the most precision barrel polishing method that TOHO KOKI Co. Ltd has developed; the centrifugal barrel finishing machine combines 0.07-0.3ф copper shots and TTP polycream for mirror finishing and ultra-fine finishing of parts. We have received rave reviews from industries for precision parts such as watch, camera, and electronics parts and miniature bearings.
