Method and device for machining work pieces that rotate around a work piece axis

摘要

Device for machining work pieces rotating around a work piece axis (Z) with a tool that rotates around a tool axis, where a clamping device (9) is transferred into a first position, a work piece to be machined is clamped on said clamping device, the clamping device (9) with the work piece clamped thereon is transferred from the first position into a spatially separated second position where it can be driven to rotate around the work piece axis (Z) by a work piece spindle (1) connected to the clamping device (9) and after the work piece has been machined, the clamping device (9) is transferred from the second into the first position, wherein the clamping device (9) is separated from the work piece spindle (1) in the transfer from the second into the first position, and connected to the work piece spindle (1) in the transfer from the first into the second position (FIG. 1).

主权项

1. Device for machining work pieces that rotate around a work piece axis (Z), with a tool that can be rotationally driven around a tool axis, a clamping device (9, 9′) on which a work piece can be clamped, said clamping device clamping a workpiece prior to machining at a first position and releasing said work piece subsequent to machining in said first position (9, 9′), and a transfer device (25) which can transfer the clamping device (9, 9′) from the first position into a spatially separated second position where it can be rotationally driven around the work piece axis (Z) during machining by a work piece spindle (1) that is connected to the clamping device (9), wherein the connection between the clamping device (9, 9′) and the work piece spindle (1) has a first connecting segment (7) that is permanently fixed at the work piece spindle (1) and a complementary second connecting segment (8) that is permanently fixed at the clamping device (9, 9′), which can be separated and reconnected by a relative motion between the first connecting segment (7) and the second connecting segment (8).
