摘要： A grinding head for a tool grinding machine is used for grinding helically grooved cutting tools. The grinding head includes a rotatable spindle supported by adjustable carriages or slides so that it can be reciprocated along one axis and pivoted about another axis perpendicular to the one axis. Further, it can be pivoted about a third axis disposed perpendicularly to the another axis. The adjustable carriages are supported on a carrier of a grinding head column so that the grinding head can be displaced about a pivot point for adjusting the head to the diameter of the tool being grooved and for adjusting the rake angle about the pivot point.

摘要： A device for grinding cutting tools having straight and spiral grooves includes a workpiece or tool spindle which is rotatable in a housing and can be set in a combined turning and advancing motion. A roller capable of engaging the outer surface of the spindle with a certain definable contact pressure is rotatable and adjustable about an axis which extends in radial direction relative to the spindle. The device further includes a locking unit for fixing the angular position of the spindle. The roller is mounted so as to be movable back and forth in the direction of the adjusting axis by means of a first actuating unit. The roller is held in frictional contact engagement with a spindle against the force of springs. The locking unit is movable by means of a second actuating unit from the first position in which it releases the spindle into a second position in which it locks the spindle. The first actuating unit is releaseable in dependence upon the position of axial advancement of the spindle.
