ABSTRACT:
An apparatus for machining the periphery of a work is provided with a grinding wheel, a holding mechanism for holding the work, and a moving mechanism for moving the holding mechanism toward or away from the wheel. A touch sensor for detecting the contact between a grinding surface of the wheel and a test piece held by the holding mechanism is connected to the wheel and the holding mechanism. The forward or backward movement of the moving mechanism is numerically controlled by a sequence controller using a microcomputer. Data representing the position of the holding mechanism when the touch sensor detects the contact between the grinding surface of the wheel and the test piece is stored in an internal memory of the controller as machining end position data (N1). The memory also prestores machining amount data (N2) and total stroke data (N2+N3). In accordance with the machining end position data (N1), the machining amount data (N2) and the total stroke data (N2+N3), the controller moves the holding mechanism with the work in place of the test piece.
