WORKPIECE TENSIONING DEVICE AND A METHOD COMPRISING A COUNTER BEARING FOR THE TOOL

摘要

The invention relates to a workpiece tensioning device for a machine tool (10), comprising at least one receiving portion (86) for a workpiece (60), said at least one receiving portion (86) comprising a wall (92) and an opening (106) by means of which the workpiece (60) can be inserted into the receiving portion (96) in a linear direction (108) and be removed in an opposite direction, a tensioning device (126) for fixing the workpiece (60) to the at least one receiving portion (96), a first access region (110) by means of which a first tool (100) engages on the workpiece (60) for a first machining process (66), a counter bearing (98) for the first tool (100), and a second access region (116; 116') by means of which a second tool (118) engages on the workpiece (60) for a second machining process (70), the first machining process (66) and the second machining process (70) taking place at different points on the workpiece (60) and with different tools (100; 118), and the workpiece tensioning device having no counter bearing for the second tool (118).
