Abstract
A machine tool comprising a table on which a spindle holding the workpiece moves in horizontal direction along the workpiece. A tool post is sidewardly movable toward the table. An arbor head is connected to the end of the post and is both axially and circumferentially movable. The arbor head includes a powered arbor for holding and possibly rotating a tool. The result is that the workpiece is movable in one direction and the arbor support is movable in two other orthogonal directions as well as being rotatable. Thereby, a variety of complex machining operations may be performed. A tool magazine and an automatic tool changer are provided.
Claims4
A machine tool for complex machining, comprising:
- a bed;
- a table which can be moved relative to said bed in the direction of a horizontal Z-axis;
- a Z-axis driver for moving said table back and forth in the direction of said Z-axis;
- a workpiece-holding headstock support-on said table so that an axis of said headstock extends in the direction of said Z-axis;
- a column secured to said bed and having a guide surface extending in the direction of an X-axis perpendicular to said Z-axis;
- an X-axis slider movably supported on said guide surface of said column;
- an X-axis driver for moving said X-axis slider back and forth in the direction of said X-axis;
- a Y-axis slider supported by said X-axis slider so that said Y-axis slider can be moved in the direction of a Y-axis perpendicular to said X-axis and to said Z-axis;
- a Y-axis driver for moving said Y-axis slider back and forth in the direction of said Y-axis;
- a B-shaft rotatably supported by said Y-axis slider so that said B-sahft can be rotated about said Y-axis;
- a tool arbor head which is attached to an end of said B-shaft and fitted with a rotatable tool arbor;
- and
- a tool arbor driver for rotating said tool arbor.
