Ultra-stable and Highly Rigid Box-type Base Structure

  • The box-type design offers a ultra-wide base structure, high quality MEEHANITE® castings, oversize hardened & ground boxed ways to ensure the best machining performance by eliminating structural distortion and deformation under heavy machining conditions.

Unique Quill-type Spindle Cartridge

  • All spindles are strictly assembled in temperature controlled room, and proven through rigorous run-in test to assure the highest quality and reliability.The unique quill-type spindle cartridge designed for easy maintenance and repair if necessary.

The GT series is ideal for high productivity turning and milling with exceptional speed, power, and capacity.

  • Oversize hardened and ground box ways, ballscrew and bearings are essential requirements for enhancing the axial and radial cutting rigidity.
  • High torque spindle motor provides the necessary power for roughing operation on tough material at low spindle speed.

Heavy-duty Spindle Design and Durable Hydraulic Chuck

  • High quality chuck with powerful hydraulic system ensures machining rigidity and accuraacy.
  • Pressure sensors are added to hydraulic system for monitoring clamping force of chuck, assuring the proper clamping of heavy parts.

Powerful VDI Turret with Milling Functions

  • Extra large turret 3-piece coupling is installed to assure the best milling performance.
  • VDI turret is servo-driven for quick and reliable tool indexing; the adjacent tool index time is only 0.6 second that reduces non-machining time and improves productivity.
  • The turret is designed with optimal tool arrangement to minimize the interference and maximize machine utilization for effective production capacity.

Versatile Tailstock Design

  • The tailstock is supported by hardened and ground boxed ways that is structurally one-piece with the machine base, which ensures the best structural rigidity.
  • The oversize quill supports heavy workpieces while maintaining machining accuracy.

High Productivity Enhancements

  • Automatic tool length measurement (opt.)
  • Automatic bar feeder system (opt.)
  • Automatic part catcher (opt.) and part conveyor (opt.)

Thermally Stable Design

  • Symmetrically designed headstock combined with effective spindle headstock exhuast fans provide superior ventilation throughout the spindle compartment, help to minimize thermal growth.
  • The spindle motor is mounted to the left side of the machine base and is designed to exhaust the heat generated from spindle motor away from the machine structure.
  • High-performance hydraulic piston pump provides high efficiency and low heat minimizing the thermal impact of hydraulic system.
  • Isolated coolant tanks minimizes the effect of coolant temperature fluctuation, reducing potential structural deformation.
  • Low heat generated work lamp is installed to minimize temperature impact.
