Embodiment Construction

[0048] 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 profiles on workpieces. The grooves are ground using a correspondingly profiled grinding wheel (5), the profile (6) of the grinding wheel (5) being crushed. According to the invention, a reshaping crush process of the grinding wheel is carried out by means of crush rollers which are driven during the process, and each of the crush rollers (8) is controlled on the basis of a measurement of the rotational speed and the current consumption, thus a relative advancement between the grinding wheel (5) and the crush roller (8) is controlled during the crush process on the basis of said measurement. The invention further relates to a grinding machine for grinding a workpiece provided with such grooves, wherein the workpiece is held in a clamping by means of a workpiece spindle head (3), and a rigidly installed crush device (7) comprising a crush roller (8) with a dedicated rotary drive (11) is additionally provided on the grinding machine. The grinding wheel (5) is applied to the crush roller (8) in order to dress the grinding wheel profile (6). For this purpose, the crush roller (8) has a profile-crushing portion (14) for profile-crushing the grinding wheel (6) with a first dressing volume and a reshaping profile-crushing portion (15), which is arranged on the same crush roller (8), for profile-crushing the grinding wheel (6) with a second dressing volume for reshaping purposes.

Description

technical field [0001] The invention according to the preamble of claim 1 relates to a method and a grinding machine for grinding workpieces having 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 d...
