Title:
GRINDING DEVICE AND METHOD FOR CYLINDRICALLY FORMED BODY WITH BOTTOM
Document Type and Number:
Japanese Patent JP3118172
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To avoid interference between a main-spindle-head of a formed body and a grinding wheel in a grinding system, in which an upper peripheral surface and a pipe-bottom outer surface of a cylindrically formed body and ground by a disc-formed grinding wheel, by forming both a cylindrical part grinding plane and a piper bottom grinding plane within one and the same grinding stone.
SOLUTION: A grinding part 2 of a grinding device 1 consists of a grinding wheel disk 30 and a grinding head 4 for rotating the stone 30. A cylinder part grinding plane 32 and a pipe bottom part grinding plane 33 are formed integrally with the grinding stone 30. The pipe bottom part grinding plane 33 is formed by a recessed part 9, which is formed by cutting off the lower corner part, which lies near to the surface of a main spindle head 11, out of the peripheral surface of the grinding stone 30, ranging over its entire periphery. As for a formed body as a body to be ground, it is held first by an installing part 46 of a formed-body attaching/detaching mechanism 40, then pushed by a pusher 48, and finally held through sucking by a formed-body holding body 12 by using vacuum force acting on an air passing hole 14 on account of air-suction by a vacuum pump.
