Off-Centerline Milling, Drilling, Tapping Capabilities Added to VTCs

Fives brings off-centerline turning, drilling, milling and tapping capabilities to its Giddings & Lewis vertical turning centers (VTCs) with a Y-axis attachment that combines a C-axis head with table and X and Z axes motions. The attachment, available fully integrated on new VTCs or as a retrofit, allows for single set-up processing of flanged parts, pumps, compressors, motor housings, fluid routing parts, intakes and exhausts, among others.

"The Y-axis attachment is a powerful package with a wide range of motion," said Pete Beyer, Director of Product Strategy and Development at Fives Giddings & Lewis. "Its power and torque are equal to our standard, heavy-duty right-angle heads, with no limits in cutting performance relative to speed. This is an affordable way to reduce set-ups and free up machine time on horizontal machining centers and boring mills that used to be required to produce these same features on turned parts."

The C-axis head provides +/-45° rotation, creating a machining range of Y-axis features of +/- the VTC table radius. The continuous power 22 kW (29 HP) attachment has a maximum spindle speed of 2,200 RPM and continuous torque of 875 Nm (645 ft-lbs.), and can be loaded manually or automatically via the machine's automatic tool changer. A live spindle accommodates standard Kennametal KM80 or Sandvik Coromant Capto C8 tooling. Coolant delivery via external nozzles on the face of the attachment or through-the-spindle coolant is provided.

"The preloaded, high-efficiency C-axis drive and high-stiffness roller bearings ensure accuracy," said a company spokesperson. "The attachment's integrated measurement system allows for accurate machining of part features."
