Title:
WATER PROOF SAND PAPER GRINDSTONE
Document Type and Number:
Japanese Patent JPH11138451
Kind Code:
A
Abstract:

To dispense with replacement of a base following abrasion of a grindstone surface and improve practicability by forming the hard grindstone surface on an upper surface of a grindstone base, brought into close contact and fixing a rear surface of a sand paper to the grindstone surface, correspondingly thereto in size, and using a polishing surface with abrasive grains as the grinding surface of the stone.

A water proof sand paper 2 is mounted on a surface 3 of a grindstone base 1, with its rear surface 5 being in contact therewith. A wing nut 18 of one pressing plate 7 is loosened, and one end of the sand paper 2 penetrates through a water proof sand paper through-hole 16. The pressing plate 7 is retreated to the position a bolt 17 reaches on an uppermost position of an oblong hole 14, and then fixed thereto by means of the wing nut 18. Namely, one end of the sand paper is fixed while being sandwiched between a pressing rubber 15 and an inclined portion 6. Similar operation is executed in respect to the other end of the sand paper 2. The rear surface 5 of the sand paper is thus brought into close contact with the grindstone surface 3. Polishing is performed by the use of a polishing surface 4 of the fixed sand paper.
