Abstract
A method of correcting an axial position of a workpiece support (1) used for removing material from a dental workpiece (2) which is held by the workpiece support (1) and is rotated together with the workpiece support (1) about a drive rotation axis (3) when material is being removed. The workpiece support (1) has at least two workpiece support parts (4, 5, 6) which can be separated from each other and connected to each other. One of the workpiece support parts (4, 5) has at least one compensation region (7) with a material projection (8) for introducing a compensation surface (9) by removing material, and the other workpiece support part (6) has a seating surface (10) for connecting to the compensation surface (9) in a form fitting manner.
Claims9
A method of correcting an axial position of a workpiece support, comprising:
- providing the workpiece support including first and second workpiece-support parts, which are separable from one another and connectable to one another, the first workpiece-support part has a compensation region with an increased diameter material overhang for forming a compensation surface by way of material removal, and the second workpiece-support part has a seat surface for form-fitting connection to the compensation surface;
- fastening the first workpiece-support part with the compensation region on a driveshaft of a machine tool, said driveshaft being rotatable about a drive rotation axis;
- removing material from the compensation region with a material-removing tool of the machine tool during simultaneous rotation of the driveshaft together with the first workpiece-support part about the drive rotation axis, the material removal resulting in the compensation surface being formed in the compensation region;
- connecting the seat surface in a final position on the compensation surface after the material removal via a form-fitting connection to the seat surface;
- and
- installing a workpiece in the workpiece support and subsequently machining the workpiece during rotation of the workpiece.
