Embodiment Construction

[0047] exist figure 1 The arrangement of the main components of the grinding machine according to the invention on the machine tool is shown in a schematic diagram in top view. A workpiece spindle seat with a workpiece spindle with a C-axis clamps the workpiece 1 . In order to optionally clamp the workpiece on the center, a displaceable tailstock 4 with the center is arranged in the extension of the longitudinal axis of the workpiece mandrel. A grinding mandrel seat with a grinding mandrel is arranged on the cross slide arranged on the machine tool, and the grinding disc 5 is arranged on the grinding mandrel. The grinding disc 5 has a set contour with which the corresponding groove is ground into the workpiece 1 . For this purpose, the grinding disc can be moved by means of the CNC axes in the X-direction, Z-direction and Y-direction and can be fed towards the workpiece 1 . In addition, a lamination device 7 is provided, which carries lamination rollers. In any case, the l...

Abstract

The invention relates to a method for grinding grooves or setting contours in workpieces. The groove is ground with a correspondingly contoured grinding disk (5), wherein the contour (6) of the grinding disk (5) is milled. According to the invention, the rolling of the subsequent setting contour of the grinding disc (5) is carried out by means of driven rolling rolls, wherein the control of the rolling rolls (8) is based on the measurement of the rotational speed and the electrical energy consumption respectively. base to proceed. Furthermore, a grinding machine for grinding workpieces with grooves is described, wherein the workpiece is held in tension by means of a workpiece mandrel seat (3) and the grinding machine is additionally provided with a fixedly mounted belt itself. The lamination device (7) of the lamination roller (8) of the rotating drive. The grinding disc (5) can be fed to the lamination roller (8) for adjusting its setting profile (6), and the laminating roller (8) has a function for adjusting the grinding disc (6) with the first adjustment volume. ) profiled rolling segment (14) for profiled rolling and a subsequent grinding disc (6) with a second adjustment volume arranged on the same rolling roll (8) The contoured lamination is followed by the contoured lamination segment (15).

Description

technical field [0001] The invention relates to a method and a grinding machine for grinding workpieces with grooves. Background technique [0002] In known methods and grinding machines for grinding workpieces with grooves, wherein in particular workpieces with meandering grooves or threads are produced, the grinding disc is contoured in such a way that after grinding the grooves When cutting into the workpiece, the outer convex shape of the contour arrangement of the grinding disc is produced as a concave shape in the form of a groove in the workpiece. Even with the use of high-powered and long-lived CBN or diamond grinding discs, the wear that occurs on the set contour of the grinding disc still leads to a deterioration of the grinding effect and is associated with it The desired shape of the groove in the workpiece deviates in a very large amount, wherein the accuracy of the set contour of the grinding disc and also its sharpness degrades during the progress of the grin...
