Document Type and Number:
Japanese Patent JP6658119
Kind Code:
B2
Abstract:
A grinding machine 1 has: a grinding wheel 6 grinding a workpiece W; a coolant supply section 8 which supplies coolant to a processing area R; a switching unit 20 supported by a headstock body 3b so that the amount by which the switching unit 20 protrudes from the end face of the headstock body 3b directed toward the machining area R is variable, and the workpiece W, Machining area R is moved from a position where the workpiece W is supported by a spindle 3a to a position where the workpiece W is separated from the spindle 3a; and a sensor unit 40 which detects the size by which the switching unit 20 projects from the end face of the headstock body 3b directed toward the machining area R. The sensor unit 40 is placed in an area located over the opposing end surface of the headstock body 3b from the end surface facing the processing area R, and detects a part of the switching unit 20 which does not protrude from the end surface of the machining area R side of the headstock body 3b.
