Abstract
In a grinding machine, a bedhas secured thereon a work headwhich rotatably supports a work spindlefor supporting a workpiece W and mounts thereon a slide basereciprocatively movable in a Z-direction parallel to the axis of the work spindle, and a wheel headcarrying a rotating grinding wheelis reciprocatively movable on the slide base in an X-direction intersecting with the Z-direction. A measuring devicefor measuring the dimension of the workpiece ground with the grinding wheel is mounted on an extreme end of a support armsecured to the slide base to extend in the X-direction, through an actuator devicewhich is operable for moving the measuring device between a measuring position for engagement with the workpiece and a parked position for disengagement therefrom. The support arm passes over the workpiece, or passes through a space between the bed and the workpiece, or passes through the inside of the bed.
