Grinding machine and control for removing burrs or fins from workpieces such as castings

Image Number 7 for United States Patent #4428162.

A method and a device for the automatic removal of burrs or fins from workpieces such as castings by a grinding process. A feed for moving the workpiece perpendicular to the grinding wheel radius is provided for grinding along the length of the burr. A second constant velocity feed of reversible and alternating direction is provided for moving the grinding wheel radially into the workpiece. The load or circumferential torque on the grinding wheel is monitored to detect the abrupt increase in torque occurring when the grinding wheel has cut through the burr and encounters the body of the workpiece, whereupon the direction of the radial feed is reversed so that the grinding process follows the contour of the workpiece.
