Ultra-Stable and Highly Rigid Box-Type Base Structure
▲The box-type design offers a ultra-wide base structure, high quality MEEHANITE® casting iron, oversized hardened, and ground boxed ways to ensure the best machining performance by eliminating structural distortion and deformation under heavy machining conditions.
▲The revolutionary base design separates chip and coolant from the base structure. Thus, it minimizes thermal distortion of machine base caused by high temperature of chips and coolant. The GT series also includes a standard chip conveyor that can be installed either from the rear or side of the machine depending on your factory layout.
Versatile Tailstock Design
▲The tailstock is supported by hardened and ground boxed ways that is structurally on-piece with the machine base, which ensures the best structural rigidity.
▲The oversized quill supports heavy work pieces while maintaining machining accuracy.
▲Optional rotary quill is ideal for high-speed, high production environment.
High Productivity Enhancements
▲Optional Automatic tool length measurement
▲Optional Automatic bar-feeder system
▲Optional Automatic parts catcher and transfer system
The GT series is ideal for high productivity turning and milling with exceptional speed, power, and capacity.
▲Oversized 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 accuracy.
▲Pressure sensors are added to hydraulic system for monitoring clamping force of chunk, assuring the proper clamping of heavy parts.
Unique Quill-Type Spindle Cartridg
▲All spindles are strictly assembled in temperature controlled room, and proven through rigorous run-in test to assure highest quality and reliable.
▲The unique quill-type spindle cartridge is designed for easy maintenance and repair if necessary.
High Precision Bearings
▲Oversized dual roller spindle bearings are used in both the front and the rear of the spindle to provide optimal spindle rigidity that is capable of handling 10mm cutting depth on hard material.
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 minimizes 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.
Powerful VDI Turret with Milling Functions
▲Extra large turret 3-piece coupling are 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.
Powerful Milling Capability
▲Installed with YCM made servo-driven VDI turret with live tooling and full C-axis contour control. The rigidity of the GT series is demonstrated through wide range of complex milling functions enhancing the productivity and versatility of the GT series.
▲The ultra high-speed servo-driven turret with all stations live enables the GT series to undertake complex machining requirements.
