GRINDING PLATE FOR A GRINDING DISK OF A GRINDING MACHINE AND PRODUCTION METHOD

Abstract

A grinding plate for a grinding disk of a grinding machine, wherein the grinding plate has a basic body and a Velcro hook layer with Velcro hooks. The basic body of the grinding plate includes a fiber-reinforced plastic and the Velcro hook layer comprises a nonreinforced plastic. A method for producing such a grinding plate is also provided. The Velcro hook layer can be molded as a thin layer of nonreinforced plastic onto the basic body made of a fiber-reinforced plastic. The grinding plate can be produced in particular in a two-component injection molding method.

DETAILED DESCRIPTION

[0043] FIG. 1 shows a preferred embodiment of a grinding plate 1 according to the present invention. The grinding plate 1 comprises a basic body 2 and a Velcro hook layer 3, the Velcro hook layer 3 comprising individual Velcro hooks 4. The Velcro hooks 4 are preferably arranged in rows 6, which are arranged between the boundaries of a surface 5 of the grinding plate 1. The rows 6 are preferably so-called radial rows 6, which are arranged at regular, preferably equidistant intervals from the outside to the inside on the surface 5 of the grinding plate 1. Preferably, the Velcro hooks 4 are arranged in radial rows 6, with the Velcro hooks 4 of the radial rows 6 being oriented in an alternating manner in the clockwise direction and in the counterclockwise direction. This allows a particularly strong and robust connection between the grinding plate 1 and a grinding attachment (not shown) to which the grinding plate 1 can be connected by means of a Velcro fastener connection. It is preferred within the meaning of the invention that the surface 5 of the grinding plate 1 acts as an active surface and is of annular design. The basic body 2 of the grinding plate 1 is formed from or comprises a fiber-reinforced plastic, while the Velcro hook layer 3 consists of or comprises a nonreinforced plastic.

[0044] FIG. 2 shows a preferred embodiment of a tool insert 7. The tool insert 7 comprises an insert frame 10 and at least one lamination assembly 8. The lamination assembly 8 is formed from individual laminations, which can be inserted into the insert frame 10 in an alternating manner, for example. A distortion cushion 9 can be arranged between the insert frame 10 and the lamination assembly 8 to counter any deformations and/or distortions.

[0045] FIG. 3 shows a preferred embodiment of a Velcro hook 4 with its dimensions. In particular, FIG. 3 shows the length L, the thickness D and the height H of an exemplary Velcro hook 4. The opening direction or longitudinal direction of the Velcro hooks 4 is illustrated in FIG. 3 by the two-dimensional arrow pointing to the right in the figure. The thickness D of the Velcro hooks 4 can also be referred to as width within the meaning of the invention.
