Abstract:
A method of manufacturing a cutting member comprising the steps:providing an auxiliary layer on one side of a cutting member,then providing said cutting member with a cutting edge by means of an electrochemical processing device, said cutting member being arranged in such a manner with respect to an electrode of the electrochemical processing device that the auxiliary layer faces away from the electrode, said auxiliary layer being applied as far as the cutting edge to be provided on the cutting member and being preserved, after provision of the cutting edge, as a functional auxiliary layer for said cutting member,providing a side of said cutting member, remote from the auxiliary layer, with a first wedge-shaped part having a relatively small wedge angle, by means of a mechanical material-removing device, said first wedge-shaped part situated at a distance from the cutting edge,then, providing said side, remote from the auxiliary layer, with a second wedge-shaped part having a relatively large wedge angle, said second wedge shaped part extending between the cutting edge and said first wedge-shaped part and being formed by means of the electrochemical processing device.
