Abstract

The invention relates to a grinding machine for sharpening (honing) blades (4) of knives, scissors, hand tools or the like, with a magazine, a feed station (1) or similar, and with a honing station (2) for the blades (4), which has two contra-rotating grinding wheels (6a, 6b). In order to automate a method to be performed using the said machine whilst maintaining a high degree of machining accuracy, it is proposed to use a robot (3) with memory-programmable control having a manipulator (5) moveable in at least four of the six possible translatory and rotational degrees of spatial freedom, a gripper head, which has a holding device for accommodating and moving a blade (4), being fixed to the manipulator (5).
