High Productivity Enhancements

  • Automatic Tool Length Measurement (opt.)
  • Automatic Bar-feeder System (opt.)
  • Automatic Parts Catcher (opt.) and Transfer System (opt.)

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.

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.

Comprehensive Thermal Control System

  • The spindle headstock is symmetrically designed with radial configuration for the best heat reduction.
  • Reinforced ventilation is located throughout the spindle head to minimize thermal growth.
  • Effective exhaust fans are installed on the spindle headstock to remove the heat generated from long running hours.
  • High performance piston pump and radiation system are added to control the temperature of hydraulic oil, which minimize the thermal impact of hydraulic system.
  • Isolated coolant tanks eliminate the effect of high coolant temperature after long running hours, which reduces structural deformation.
  • The spindle motor sits outside of the machine base to isolate the heat generated from spindle motor after long operations.
  • Low heat generated work lamp is installed to minimize temperature impact.

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.

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.
  • Optional live quill is ideal for high-speed, high production environment.
