Abrasive Powder
GRIDING WHEEL
RING-TYPE GRINDSTONE WITH NUTS
FITS EASILY
AND
GRINDS SAFELY!
FEATURES
- Easy mounting : It can bolted to the base ring by tightening nuts.
- Lightweight : Light in weight for easy handling.
- Economical : Unlike glued types, it has no set-in loss.
- Safety : Bolted rather than glued, it is free of center wobbling for safe grinding.
APPLICATION
In addition to sharpening edged tools
such as veneer and slicer knives, it can be used in place of ordinary
ring-, cup-, and single-dent-type grindstones.
MOUNTING PROCEDURES
|
|
|
¨ç Wipe off
dust and soil from the base ring and then fit it to
the flange. |
¨èMount the
grindstone to the base ring. Be careful that no foreign
matter is caught between the grindstone and the base
ring. |
¨é Make sure
that grindstone is secured to the base ring with bolts
evenly tightened and that it does not wobble. |
CAUTIONS ON HANDLING
- Be sure to use bolts provided by us.
- Make sure that no foreign matter is caught between the grindstone and the base ring.
- Alternately tighten bolts in a symmetrical position. Be sure to tighten them evenly.
- Since the grindstone itself is made of the same material used for fabricating other types of Takakura grindstone, handle it with care.
- The grindstone can be used until it wears to the edge of the coated area. Under no circumstances is the coated area to be used for grinding.
FINISHING GRINDSTONE
- In addition to the ring-type grindstone with nuts, Takakura manufactures various types of cup-type finishing grindstones for sharpening blades.

Applications |
HI-LAP |
It has been used for general metal grinding. Especially good for high-tensile materials. It is widely used for bearing balls, steel balls, optical lenses grinding. |
WHITE HI-LAP |
It is used for finish-grinding of implement-steels and special steels. And it is also used for stainless steels grinding with grind-belts or buffs. For general cutlery grinding as well. |
TAKAMIJIN |
Because of it's low hardness and ball shape, it makes less damages on the materials. it exhibits superior performance in lustrous finishing. Good for bearing balls, optical lenses grinding. |
BLACK HI-LAP |
Good for grinding low tensile materials, such as glass, optical lenses, quartz, etc. It is used for finish-grinding of stones and pottery. |
CREEN HI-LAP |
It has the highest hardness, brittleness and heat conductive. It is good for grinding of heat-dislike materials, such as super-hard materials, quartz, optical lenses, coils, etc. |
