Title: Method for grinding outer periphery of throw-away tip
Inventor: NAGASAWA KENJI
IPC: B24B3/34
Filed: 1988-01-14
Abstract: PURPOSE:To accurately grind a round corner of a throw-away tip by correcting the position of round corner of the throw-away tip with reference to the outer periphery while correcting the corner radius so that the round corner is formed to continue to adjacent outer periphery. CONSTITUTION:After the whole outer periphery of a throw-away tip S1 is ground, the diameter phi1 of an inscribed circle in this tip S1 is measured. A difference between the measured diameter and the reference diameter phi0 of a reference inscribed circle in a reference throw-away tip S0 is substituted in a preset correction formula to correct the position of round corner M1 with reference to the outer periphery. Then, the corner radius R1 is corrected to grind the round corner M1 so that the round corner M1 is formed to continue to the adjacent outer periphery. Thus the dispersion of position of the round corner M1 with reference to the outer periphery can be restrained small so that the round corner M1 can be accurately ground.

Filed: 1989-01-13
Abstract: PURPOSE:To enable a substantial improvement of a maintainability by constituting a back-up seal part of an axially flexible sealing means to make the seal part to be maintainance-free. CONSTITUTION:In case that a boundary member of a cover gas 9 in a nuclear reactor breaks unexpectedly, a sealing mechanism is prepared as a back-up system to prevent a leakage of the cover gas 9 in the nuclear reactor, to an outside of a nuclear reactor pressure vessel. A sealing part 17 of the back-up system is constituted with an axially flexible sealing means 20, a welded bellows, for instance. Accordingly, when a movable member, that is, a latch axis 16, moves vertically, the sealing means 20 expands or shrinks vertically to perform a back-up sealing. This sealing mean had no sliding part, differently from an ordinary packing. With this structure, in case that a metal is adopted as a sealing material, a sealing function and a durability is extraordinarily improved.
