Abstract

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.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 208 words
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.
Claim 2
Dependent Claim 208 words
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.
Claim 3
Dependent Claim 52 words
A machine tool is recited in claim 1: wherein said rotatable tool arbor is supported rotatably with a rotation axis perpendicular to said Y-axis and is provided with a locking mechanism for keeping said tool arbor from rotating; and further comprising a B-shaft indexing mechanism for indexing said B-shaft about said Y-axis.
Claim 4
Dependent Claim 39 words
A machine tool as recited in claim 2, further comprising: a tool magazine provided over said column; and a tool changer for changing a tool held in said tool magazine to a tool held by said tool arbor head.
Claim 5
Dependent Claim 32 words
A machine tool as recited in claim 3, wherein a guiding surface of said bed on which said table is moved is inclined at an angle of about 60° to the horizontal.
