5-axis mill-turn universal machining center

Grob Systems Inc. says its G550T 5-axis mill-turn universal machining center provides the greatest possible positioning flexibility due to the axes' large swivel range (230ﹾ in the A'-axis and 360ﹾ in the B'-axis). A horizontal spindle position permits the longest possible Z-travel path and optimum chip fall, the company adds.

Grob Systems Inc. says its G550T 5-axis mill-turn universal machining center provides the greatest possible positioning flexibility due to the axes' large swivel range (230ﹾ in the A'-axis and 360ﹾ in the B'-axis). A horizontal spindle position permits the longest possible Z-travel path and optimum chip fall, the company adds.

The machining center can be used in challenging 5-Axis applications, including power skiving capabilities and fir tree mill finishing.

The G550T features a unique arrangement of the three linear axes that minimizes the distance between the guides and the machining point (TCP), providing stability in part production. A tunnel concept permits large components (even in the case of with extremely long tools) to be swiveled and machined within the work area without collision.

The three linear and two rotary axes allow 5-sided machining, 5-axis simultaneous interpolation, as well as GROB TRAORI-turning for precise cutting control.

Glossary terms in this article

  • machining center
    CNC machine tool capable of drilling, reaming, tapping, milling and boring. Normally comes with an automatic toolchanger. See automatic toolchanger.
  • interpolation
    Process of generating a sufficient number of positioning commands for the servomotors driving the machine tool so the path of the tool closely approximates the ideal path. See CNC…
