Claims11
A machine tool with at least one motor spindle rotatably driving a respective tool and a work piece table, at or on which the at least one work piece is directly or indirectly clamped, through a pallet carrying the work piece during the machining process, by a clamping device and the clamping device comprises at least a clamping means, a clamping device and a clamping power connection (52), wherein the clamping means cooperates with the work piece or the pallet carrying the work piece, the clamping drive drives, using the power provided by the clamping power connection, the clamping means for clamping and/or releasing the work piece and the clamping power connection is temporarily connectable with a power transmission connection piece, wherein the power transmission connection piece is operatively connected to a power source and the power transmission connection piece is movable in a forward or backward direction with respect to the clamping power connection by a moving drive.
A machine tool with at least one motor spindle and a work piece table, on which the at least one work piece is clamped during the machining, by means of a clamping device and the clamping device comprises at least one clamping mean, a clamping drive and a shaft stub, wherein the clamping means cooperates with the work piece or with a pallet carrying the work piece, the clamping drive, using the energy provided by the shaft stub, drives the clamping means for clamping and/or releasing the work piece and the shaft stub is temporarily connectable to a screwdriver or the motor spindle, wherein the screwdriver or the motor spindle are movable to and from the shaft stub by a movement drive.
A machine tool with at least one motor spindle and a work piece table, on which the at least one work piece is clamped during the machining, by a clamping device, and in the work piece table a lifting device is provided, wherein the lifting device comprises at least one lifting means, one lifting drive and one shaft stub, wherein the lifting means cooperates with the rolling track, the lifting drive drives, using the energy provided by the shaft stub, the lifting means in order to lower and/or lift the rolling track and the shaft stub is temporarily connectable with a screwdriver or with the motor spindle, wherein the screwdriver or the motor spindle are movable towards the shaft stub or back by means of a movement drive.
