Abstract

Zwischen dem Werkzeug und einem geraden Jointstein (25) wird eine Radialzustellbewegung vorgenommen, dessen wirksamer Jointbereich länger ist als die Schneide (9). Damit die Schneide (9) bei geringem Verschleiß des Jointsteines (25) optimal gejointet werden kann, wird zwischen dem Jointstein (25) und der Schneide (9) während des Jointvorgangs in Längsrichtung der Schneide (9) wenigstens ein Relativhub ausgeführt, der kleiner ist als die Länge der Schneide (9). Bei diesem Verfahren findet während des Jointvorganges in einer Längsrichtung der Schneide (9) eine axiale Relativbewegung zwischen dem Jointstein (25) und der Schneide (9) statt. Dieser Hub ist kleiner als die Länge der Schneide (9). Durch diese Hubbewegung wird eine Riefenbildung an der Schneide (9) des Schneidmessers (3) vermieden. Außerdem ist der Verschleiß des Jointsteins (25) gering, da immer eine sehr große Fläche des Jointsteines (25) im Eingriff ist. Mit dem Verfahren wird eine mikroskopisch glatte Schneide (9) erhalten, die zu einer hohen Oberflächenqualität des bearbeiteten Werkstückes führt.

Figure 00000001
A radial feed movement is carried out between the tool and a straight joint stone (25), the effective joint area of which is longer than the cutting edge (9). So that the cutting edge (9) can be optimally jointed with little wear of the joint stone (25), at least one relative stroke, which is smaller, is carried out between the joint stone (25) and the cutting edge (9) during the jointing process in the longitudinal direction of the cutting edge (9) than the length of the cutting edge (9). In this method, an axial relative movement between the joint stone (25) and the cutting edge (9) takes place in a longitudinal direction of the cutting edge (9) during the jointing process. This stroke is less than the length of the cutting edge (9). This stroke movement prevents scoring on the cutting edge (9) of the cutting knife (3). In addition, the wear of the joint stone (25) is low, since there is always a very large area of the joint stone (25) in engagement. A microscopically smooth cutting edge (9) is obtained with the method, which leads to a high surface quality of the machined workpiece.
