Title:
METHOD AND DEVICE FOR PRECISELY GRINDING OUTER AND INNER SURFACE OF RING
Document Type and Number:
Japanese Patent JP2530959
Kind Code:
B2
Abstract:
PURPOSE: To enable high-precision measurement without being disturbed by vibration, by providing measuring heads so that they may be adjusted in reciprocating in the radial direction in relation to the front surface to be machined.
CONSTITUTION: Non-contact measurement is performed by at least two same measuring heads 5, cleaning liquid as a hydraulic pressure measuring medium is caused to flow from at least one nozzle opening in the measuring heads 5 and introduced to a cleaning liquid layer 7 so that the hydraulic pressure measuring medium may not be jetted to the outside. Next, the cleaning liquid layer 7 is fed on the ring surface to be machined to form the cleaning liquid layer 7 between the measuring heads and the ring surface. As a result, although non-roundness is generated by fastening, hazard vibration is not generated on a measuring system.
