Method for correcting an axial position of a workpiece support

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.

         11 . The kit for forming the workpiece support as claimed in  claim 10 , wherein the seat surface comprises a cylinder shell or an otherwise rotationally symmetrical shaping. 
     
     
         12 . The kit for forming the workpiece support as claimed in  claim 10 , wherein the first workpiece-support part comprises a sleeve that defines a cylindrical cavity and radially extending wall within the sleeve, and two axially extending holes are located in the radially extending wall and are configured for attaching the first workpiece-support part to a further workpiece support connected to a driveshaft of a machine tool. 
     
     
         13 . The kit for forming the workpiece support as claimed in  claim 12 , wherein the first workpiece-support part has a longitudinal stop formed thereon with an additional axially extending material overhang extending from one axial end of the sleeve, and the longitudinal stop is configured to be shortenable by way of material removal. 
     
     
         14 . The kit for forming the workpiece support as claimed in  claim 12 , wherein the second workpiece-support part includes a radially extending index pin extending into the cavity of the second workpiece-support part. 
     
     
         15 . The kit for forming the workpiece support as claimed in  claim 12 , wherein the compensation region is formed on a portion of the outer surface of the sleeve, and surface regions of the compensation region have a greater outside diameter than a remainder of the sleeve. 
     
     
         16 . The kit for forming the workpiece support as claimed in  claim 12 , wherein the second workpiece-support part includes a second radially extending wall, and two screw apertures extend axially through the second radially extending wall. 
     
     
         17 . The kit for forming the workpiece support as claimed in  claim 16 , wherein the first workpiece-support part includes two corresponding screw apertures in the radially extending wall that are aligned with the screw apertures in the second radially extending wall of the second workpiece-support part. 
     
     
         18 . The kit for forming the workpiece support as claimed in  claim 17 , wherein the two corresponding screw apertures in the radially extending wall of the first workpiece-support part are spaced apart in a circumferential direction from the two axially extending holes. 
     
     
         19 . The kit for forming the workpiece support as claimed in  claim 17 , wherein screws are adapted to be inserted through the screw apertures and the corresponding screw apertures in order to fasten the second workpiece-support part on the first workpiece-support part. 
     
     
         20 . The kit for forming the workpiece support as claimed in  claim 16 , wherein the second workpiece-support part includes an axially extending workpiece adapter that extends from the second radially extending wall in an axially opposite direction from the cavity, and the two screw apertures are formed at least partially in the axially extending workpiece adapter. 
     
     
         21 . The kit for forming the workpiece support as claimed in  claim 10 , wherein the second workpiece-support part includes an axially extending workpiece adapter that extends in an axially opposite direction from the cavity of the second workpiece-support part. 
     
     
         22 . The kit for forming the workpiece support as claimed in  claim 21 , wherein a radially extending threaded bore extends into the axially extending workpiece adapter.
