Automatic copying belt grinding machine

Claim 1

An automatic copying belt grinding machine, comprising a Z-axis slide movable in a vertical direction, an X-axis slide slidably mounted on said Z-axis slide to shift horizontally, a swivelling grinding head mechanism mounted on said X-axis slide, a duplex electronic copying sensor having a portion for sensing the contour of a model and a swivelling portion for sensing the inclination of a surface of said model mounted on said X-axis slide, a pair of fixture tables rotatable in synchronization with each other upon which a model related to the duplex electronic copying sensor and a workpiece related to said swivelling grinding head mechanism are respectively vertically installed, and an electronic control unit for controlling said Z-axis slide and said X-axis slide and said copying sensor and said grinding head so that they function in a copying mode, whereby the grinding machine copy grinds the workpiece continuously and spirally along the peripheral direction over its entire length, while the tangential speed of the grinding head relative to the workpiece is kept constant and the grinding head is positioned normal to the surface of the workpiece at the point of contact.
