Embodiment Construction

[0029] figure 1 A grinding machine according to the invention can be seen in a view in a cross-section perpendicular to the feed direction V. An abrasive element 1 in the form of an abrasive cloth or abrasive belt is mounted exchangeably on a holding device 2 . The holding device 2 itself is carried by at least one eccentric shaft 3 perpendicular to the grinding plane, ie perpendicular to the grinding surface of the abrasive element 1 , which can be driven in rotation by an electric motor 4 at a variable rotational speed. The abrasive material 1 is forced to perform a circular grinding movement in the grinding plane by the eccentric shaft 3 . The electric motor 4 itself is fixedly connected to a grinder frame 5 . The supporting device of at least one of the provided eccentric shafts 3 can move in one direction of the grinding plane, preferably in the Y direction perpendicular to the feed direction V, so as to compensate for the longitudinal expansion of the grinding machine ...

Abstract

Disclosed is a grinding machine comprising oscillating driving means ( 3, 4 ) for setting grinding means ( 1 ) into an oscillating grinding motion and an actuation device ( 7 ) that is provided with a plurality of actuation areas ( 8 ) which can be triggered such that different zones of the grinding means ( 1 ) are alternately actuated independently of the oscillating grinding motion.

Description

technical field [0001] The invention relates to a grinding machine with an oscillating drive for setting an abrasive element into an oscillating grinding motion. The invention also relates to a method for grinding a workpiece with such a grinding machine by means of an oscillating grinding movement. Background technique [0002] Such a grinding machine is described, for example, in the embodiment of a belt grinding machine in EP 0 543 947 B1. The abrasive elements attached to a plate and the vibration drive are coupled to the grinder frame in such a way that a second movement of the plate relative to the grinder frame is superimposed on the translational orbital movement. The formation of regular grinding patterns should be avoided by the two superimposed movements. These two superimposed movements are coupled to each other. [0003] For example, EP 0 155 380 B1 discloses a belt grinding machine having a multi-section pressure bar with a plurality of pressure shoes arrang...
