Abstract

The method of grinding or sharpening axial-thrust cutting tools consists in bringing the tool to a first position for grinding the rake plane, the tool axis lying in a vertical plane inclined to the horizontal median plane of the grinding wheel according to the rake angle, with the tool centre coincident with the point of intersection of the tool axis with the pivot axis of the jig supporting the tool-holder, the tool being subsequently brought to another position for grinding the cutting face passing through the centre of said tool by pivoting said jig about said jig pivoting axis, in combination with an angular setting, obtained by pivoting said tool holder about its pivot axis passing through said point of intersection, and eventually bringing said tool to a third position for grinding the small face bounding the cutting lip in the central portion of the tool tip, by pivoting said jig in a direction opposite to the direction of the movement having led to said second position.
