Abstract (en)

[origin: EP0802018A1] The device has a grinding tool (1) which is cyclically oscillated at right angles to the longitudinal axis (2) of the grinding tool alignment pin (7). The pin is in line with the drive shaft (10,17) which rotates the grinding tool. An eccentric (9a) provides the periodic motion to the grinding tool. The eccentric is part of a quill drive (9) with an eccentric hole (24) in which a mount (22) for the grinding tool is supported so that it can move to-and-fro. The grinding tool can be set at an angle to the workpiece (6).
