PARALLEL TWIN-SPINDLE CNC TURNING CENTERS
From high efficiency production demand for automobile industry, the GTH series CNC turning center with advanced parallel twin spindles, twin turrets structure and high efficiency automation system, the GTH provides automatic loading, front/rear cutting, unloading and work-piece detecting, which make its ultimate machining capabilities a coordinated process. Furthermore, the GTH series fulfills all types of plate-shape and short-shaft work-piece of automatic mass production needs.
Revolutionary Parallel Twin-spindle Structure Design
Low mechanical interference, easy to integrated twin spindles machine, single spindle machine and all types of automatic system into a highly efficient production line.
Assist by robot arm and flipping device, the twin spindles design can provide front/rear cutting simultaneously but also front cutting simultaneously to meet the best process arrangement of mass production.
Compare to normal twin spindles turning center, GTH is more compact and smaller floor space.
Loading by robot arm on 2nd spindle increase the working efficiency more than 5 times base on twin spindles simultaneous receiving design, shorten non-cutting time.
More Flexible Process Arrangement
Higher Unit Area Production Output Value
Excellent Expandability

Chip RemovalSafety MaintenanceMovable protection door between two spindles which can prevent chips contamination of another processing area.
When the machine is not running, operator can rotate the movable protection door to increase the space of operation.
Optimized chip removal design, chips can easily fall into chip conveyor and quickly take away from the processing area.
Rear discharge chip conveyor makes GTH production line more compact. It is not only improves the utilization rate of factory space, but also good to achieve central chip conveyor belt design.

By using Finite Element Analysis ( FEA ) and high tension Meehanite casting structure, super rigidity frame of spindles, turrets and saddle are reaching the optimal reinforcement. Mechanical strength is well enough to load extremely heavy cutting while maintaining long period of super high accuracy. Moreover, super rigidity of machine can extend life time of tools.
Independant Twin Base Design
It can efficiently decrease cutting resonance of two spindles systems and increase reliability of machining, roundness and roughness of appearance.
Ensure the single spindle model or twin spindles models can be flexibly provided under the conditions of high rigidity structural design to meet the configuration requirements of various production lines.

Full travel of saddle and turret are firmly supported by bed, and distance of overhang of turret is shorter which increase cutting rigidity.
X / Z axes adopt super rigidity box ways design which is through heat treatment and precise finishing processes. And long span design of traverse can maximize strength and precision.
Contact surfaces of all slides, headstock, turret, and ball screw bearing housings with the machine bed are precision hand scraped to provide maximum assembly precision, structural rigidity, and load distribution.

NC INTELLIGENCEThe new generation of G.LINC intel l igent HMI system is with faster hardware, operating systems and more powerful software. We have a breakthrough technology and ideas to build the G.LINC, it is ready to work with you into the next generation of intelligent manufacturing.
The 12-station ( Opt. 16 ) GOODWAY live tooling turret offers 12 ( 16 ) stations available for live tooling ( live tooling tools rotate in working position only ).
With the latest technology, live tooling is driven by an AC servo motor to provide ample power, in the form of torque. Now, even the toughest of jobs may be tackled without a sweat.
The FANUC Cf-axis servo motor generating an ultra-high resolution of 33,000,000 pulses per spindle rotation and high output torque, machined surface finishes are much superior. Also, dynamic accuracy is within ± 0.02° even under heavy cutting loads.
