Abstract
A machine tool for cutting workpieces, the machine tool having a tool slide shiftable on or along a machine tool table as support of a machining unit. The machining unit has at least one work spindle and a workpiece support for receiving the workpieces to be machined. For enabling fast machining including an accurate and rapid positioning of the machining unit with as few linear guidances as possible, the tool slide has a transverse support shiftably guided on or along the machine tool table and also has two cross slides shiftable in its longitudinal direction. The machining unit is jointedly arranged between the cross slides via a coupling mechanism having at least two dimensionally stable swivel arms for axially moving the work spindle.
Claims40
A machine tool for cutting workpieces comprising:
- a machine tool table;
- a motor;
- a machining unit comprising at least one work spindle;
- a tool slide shiftable on or along said machine tool table by means of said motor, said tool slide providing support for said machining unit;
- and
- a workpiece support for supporting workpieces to be processed wherein said tool slide further comprises a transverse support shiftably guided on or along said machine tool table, said transverse support comprising two cross slides shiftable in a longitudinal direction, said machining unit being jointedly arranged between said cross slides for axially moving said work spindle via a coupling mechanism, and said coupling mechanism comprising at least two dimensionally stiff swivel arms.
