Abstract (en)

[origin: US4817338A] 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.
