Benefits of technology

[0007]The invention also relates to a method for operating a grinding or polishing apparatus which may preferably have one or more of the features described above and, against the background of the restrictions to achieving the stated object that exist in the prior art and were explained at the beginning, proposes that grinding or polishing elements are filled into the treatment container, that one or more workpieces is or are secured to the workpiece holder, that the treatment container and the grinding or polishing elements contained therein are made to oscillate by means of at least one oscillation exciter and that the workpiece or workpieces secured to the workpiece holder is or are partially or completely submerged in the fill of the grinding or polishing elements through the opening in the treatment container by means of the workpiece holder during the oscillatory excitation of the treatment container with the grinding or polishing elements, and that subsequently the workpiece holder is securely clamped magnetically on the clamping plate or plates which is / are disposed outside the treatment container and / or on a portion of the treatment container that is an upper portion with respect to the height of the container. The method according to the invention advantageously makes it possible that the fill of grinding or polishing elements can remain inside the container when workpieces are inserted and taken out, whereby the setup times and downtimes are shortened and cost-effective operation is made possible. The oscillatory excitation of the grinding or polishing elements and the fluidization thereof brought about as a result reduces the penetration resistance for the workpieces into the fill of the grinding or polishing elements.

Problems solved by technology

This results not only in lower energy consumption but also in an insensitivity to failure of the power supply.
The oscillatory excitation of the grinding or polishing elements and the fluidization thereof brought about as a result reduces the penetration resistance for the workpieces into the fill of the grinding or polishing elements.

Embodiment Construction

[0027]With reference to FIGS. 1 to 6, a grinding or polishing apparatus 1 according to the invention as provided by a first preferred exemplary embodiment is firstly presented. This apparatus has a pot-like treatment container 2. This comprises a cylindrical side wall 3 and a plate-shaped bottom 4, which on the underside is supported at two opposite edges on a respective group of four cylindrical compression springs 5 on a base 6. At diametrically opposite regions of the side wall 3, an unbalanced drive 7 is respectively mounted on a flange 8, the pattern of holes in which allows the unbalanced drive 7 to be fixedly connected to the treatment container at different angles of inclination (for example with respect to a horizontal reference plane). Alternatively, a stepless adjustment of the angle of inclination would also be conceivable, for example by means of clamping by workholding claws. The two unbalanced drives 7 together form a first oscillation exciter 9. Attached to the under...

Abstract

A grinding or polishing apparatus and method for grinding or polishing at least one workpiece, in particular having a ferromagnetic property, by way of barrel finishing, having at least one pot-like treatment container, mounted so as to be able to oscillate, for receiving one or more workpieces and grinding or polishing elements, also having at least one workpiece anchoring device for disposing one or more workpieces within the treatment container and for connecting the workpieces to the treatment container in a releasably secured manner, and also having at least one oscillation exciter, by means of which the treatment container can be oscillated, and in that the workpiece anchoring device comprises at least one switchable clamping plate, in particular at least one clamping plate having one or more permanent electromagnets, which is adapted such that a magnetic field emanating outwardly from a clamping surface of the clamping plate can be selectively activated or deactivated.
