Abstract
A machine tool for machining a workpiece with a tool moved relative to the workpiece is provided with a bed (13) providing a base, a column (15) vertically mounted on the bed (13), and a carriage (27) having supporting columns (27a and 27b), disposed on either side thereof, for oscillatably supporting a table (35), the carriage being oriented so that one (27b) of the supporting columns (27a and 27b) is positioned adjacent the column (15) and the other (27a) of the supporting columns is positioned away from the column (15).
Claims7
A machine tool for machining a workpiece with a tool moved relative to the workpiece, comprising:
- a bed providing a base;
- a column vertically mounted on one end portion in the longitudinal direction of the bed;
- and
- a carriage having supporting columns, disposed on either sides thereof, for oscillatably supporting a table about an oscillation shaft extending parallel to the longitudinal direction of the bed to which table a workpiece is mounted, the carriage being oriented so that one of the supporting columns is positioned adjacent the column and the other of the supporting columns is positioned away from the column.
A machine tool for machining a workpiece with a tool moved relative to the workpiece, comprising:
- a bed providing a base;
- a column vertically mounted on one end portion in the longitudinal direction of the bed;
- a carriage mounted on an upper face of the bed for linear motion in the longitudinal direction of the bed;
- a table mounted on the carriage for oscillation about an oscillation shaft extending parallel to the longitudinal direction of the bed;
- a saddle mounted to a front face of the column for horizontal linear motion perpendicular to the longitudinal direction of the bed;
- and
- a spindle head, mounted to the saddle for vertical linear motion perpendicular to the horizontal linear motion of the saddle, for supporting a main spindle for rotation about a vertical axis, the main spindle holding a tool to face the table.
A machine tool for machining a workpiece with a tool moved relative to the workpiece, comprising:
- a bed providing a base;
- a column vertically mounted on one end portion in the longitudinal direction of the bed;
- a carriage mounted on an upper face of the bed for linear motion in the longitudinal direction of the bed;
- a table mounted on the carriage for oscillation about an oscillation shaft extending parallel to the longitudinal direction of the bed;
- a saddle mounted to a front face of the column for horizontal linear motion perpendicular to the longitudinal direction of the bed;
- a spindle head, mounted to the saddle for vertical linear motion perpendicular to the horizontal linear motion of the saddle, for supporting a main spindle for rotation about a vertical axis, the main spindle holding a tool to face the table;
- workpiece changing means, mounted at one side of the bed with respect to the longitudinal direction of the bed, for changing a machined workpiece on the table with a non-machined workpiece;
- and
- access means for allowing to access a workpiece on the table from the side opposite to the workpiece changing means with respect to the longitudinal direction of the bed;
- wherein the workpiece changing means comprises a pallet changer for changing a pallet to which a workpiece is mounted;
- and
- wherein the pallet changer includes:
- a rotary arm rotatable about a vertical axis;
- and
- a shifter arranged between the rotary arm and the table for reciprocation in the horizontal direction perpendicular to the longitudinal direction of the bed, the shifter receiving a non-machined workpiece mounted to a pallet from the rotary arm together with the pallet to transport them to the table, and also receiving a machined workpiece mounted to a pallet from the table together with the pallet to transport them to the rotary arm.
