New Rotary Table Allows Accurate Machining of Bladed Turbine Parts

Grob Systems, Inc., announced November 11 that it had introduced a new VARIO-brand rotary table for accurately machining bladed turbine, thin walled and slender parts. The VARIO table can be configured in a basic form or with two dynamic, independently operating direct drive B-axes. According to Grob, the B-axes have specialized drive configurations to reduce stress during roughing and prevent component distortion.

The VARIO rotary table is reportedly available on Grob’s 5-Axis G350 and G550 Universal machining centers, which Grob says can provide good surface quality on challenging materials or large parts. For operator flexibility, the rotary table has a movable counter-holder axis for part sizes up to 27.6 inches or 700mm blank length.

In a statement accompanying the rotary table’s release, Grob System’s Universal Machines Sales & Proposals Manager Derek Schroeder said the new product would improve manufacturing processes for thin or bladed parts production.

“We are pleased to offer manufacturers with a new, reliable rotary table solution for optimizing precision and surface finish on bladed turbine parts and other demanding thin walled parts,” Schroeder said. “The new VARIO Rotary Table sets new standards for the manufacture of turbine blades of all kinds.”
