The present invention relates to a workpiece holder device for workpieces (105) to be machined on multiple sides, wherein the workpiece (105) can be held axially and radially relative to the first axis (R) between a first workpiece holder (104, 106), operatively connected to at least one support spindle (103) of the workpiece holder device and rotatable about the first axis (R), and at least one second workpiece holder (107), operatively connected to at least one drive spindle (111) of the workpiece holder device and rotatable about the first axis (R), by force locking by means of a clamping force which can be built up in the manner of a vice between the first workpiece holder (104, 106) and the second workpiece holder(107) in the axial direction of the first axis (R) and acting on the opposite sides of the workpiece (105). The first workpiece holder has at least one first clamping element (104, 106) with a first smooth clamping face (119) facing towards the second workpiece holder (107) and/or the workpiece (105) and the second workpiece holder has at least one second clamping element (107) with a second smooth clamping face (124) facing towards the first workpiece holder (104, 106) and/or the workpiece (105). The workpiece holder device is characterised in that the first clamping element (104, 106) and/or the second clamping element is or are constructed of a plurality of parts, wherein a first clamping element part (104) of a particular clamping element can be moved relatively to the second clamping element part (106) of the clamping element in such a manner that a first angle (a') between the first axis (R) and the normal of the first clamping face (119) and/or a second angle between the first axis and the normal of the second clamping face can be varied. |
