Title:

DEVICE AND METHOD FOR MACHINING IN WHICH COOL AIR COOLING IS USED

Document Type and Number:

WIPO Patent Application WO/1999/033616

Kind Code:

A1

Abstract:

A machining device using cool air cooling capable of performing the conditioning of a machining tool at an appropriate timing for a work piece, wherein, when a work piece (W) is ground while cooling air is supplied to a portion to be ground (P) between the work piece (W) and a grinding stone (17), the surface temperature of the work piece (W) is detected by a temperature detecting device (90) and, when a surface temperature reaches a temperature at which the conditioning is required, a command for conditioning of the grinding wheel (17) is given, whereby a grinding wheel table (16) and a grinding wheel conditioning device (42) are moved, the grinding wheel (17) is conditioned by a dressing tool (44), and the sharpness of the grinding wheel (17) is recovered. Because the temperature at which the conditioning is required is determined based on the relation between the temperature of the work piece (W) and a residual stress, the grinding stone (17) can be conditioned at an appropriate timing for the work piece (W).
