Grinding Head

an attachment that makes it possible to grind workpieces on metal-cutting machine tools. Located within the housing of a grinding head is a spindle running on roller or gas bearings with a grinding wheel attached to the front section; the rear section of the spindle is rotated by means of a belt drive from an electric or compressed-air motor or from a spindle of the machine tool. Grinding heads can be mounted on lathes for external and internal grinding, on standard planers and planer-type milling machines for grinding long surfaces, and on surface and internal grinding machines for grinding holes greater than 30 mm in diameter.
