Abstract (en)

[origin: WO0147665A1] The invention relates to a method and device for grinding fluted tools (10) that have an essentially circular envelope curve, in particular, for grinding spiral fluted tools. The device provided with a steady for guiding the tool to be ground comprises a guideway (8) with at least two inner lateral faces. The lateral faces each extend in planes in a manner that is essentially parallel to the longitudinal axis of the tool to be ground and they from an angle for accommodating the tool to be ground, whereby the tool to be ground rests each time with at least two circumferential points (a11, a12) of its essentially circular envelope curve at least on two of the inner lateral faces of the guideway. In order to carry out the inventive method, a tool to be ground is appropriately clamped and pressed into the guideway by means of at least one grinding wheel (41) while the flutes are ground.
