摘要

The bed slide carriage (16) and the second and third guides (18,21) are so configured and arranged that the tool holder (24) rotary axis (26) can be hoisted from a spindle axis plane. This plane is defined by the spindle axis (48) and the direction of the tool holder rotary axis, as well as lowered into this plane. The tool holder is displaceable from a position near the second slide carriage over the spindle axis. ADVANTAGE - Easy prevention of tool collision with other machine parts, and universal applicability.
