MAXIMUM STRENGTH CONSTRUCTION

Finite Element Analysis ( FEA )

The Finite Element Analysis ( FEA ) provides optimal machine design and light-weight structure advantage while ensuring super rigid of machine.

Super Rigid Casting Structure

The super rigid bed and column are of MEEHANITE casting. It is capable of withstanding much greater stress without deforming and provides maximum vibration dampening.

Reinforced Rib Column

Reinforced rib column integrated with cross rail stay firmed on the machine base that provide spindle head abundant support rigidity, also shorten the distance between tooling to the column and reduce tooling spindle overhang, strengthen processing rigidity.

High Precision Hand Scraping

Contact surfaces of all slides, bed and column are precision hand scraped to provide maximum assembly precision, structural rigidity, and load distribution.

Heavy Duty Ground Box Ways

Extra wide hardened and ground box ways on X, Z and W axes. They are precision machine and widely spaced for maximum strength. The box way design also provides the rigidity needed for heavy duty and interrupted turning applications.

W-axis Moving Cross Rail Mechanism

By W-axis moving ram to reduce the distance between tooling and beam, this can decrease square ram overhang, suitable for heavy cutting or disc type parts request.

Positioning & Clamping Mechanism

Positioning fixed device is composed of two sets of live locking bolts and four sets of hydraulic clamping devices which can provide abundant clamping force, decrease vibration when cutting, ensure processing accuracy.

Sectional Guide Ways Design

Not only W-axis rail integrated with column, also use new sectional design to provide good anti-vibration capability, construction not deformed during heavy cutting.

ULTIMATE TURNING POWER

Super-sized Square Ram

The square ram on the tooling spindle is adopted with a closed-type and fixed with 8 sets of powerful wedges. This offer the GV-1 series with greater structural rigid and machining accuracy compared peer models with a semi-closed type square ram structure.

Z-axis is balanced by dual counterweight hydraulic cylinder, this can avoid unbalanced torque and make sure GV-1 excellent processing accuracy.

Coolant & Chip Removal Capacity

Machine standard include coolant through spindle and coolant around spindle. High pressure coolant system ( 70 bar ~120 bar ) is optional function.

Wide chip trough is designed by large angle of inclination, by working with chips wash down coolant system, chips can be easily brought out through cutting area.

Max. Clamping Range

Standard 4-jaws individual manual chuck.

High Torque Work-piece Spindle

The high torque work-piece spindle is equipped with a powerful FANUC 45 kW spindle motor that delivers a maximum torque output of 23,900 Nm*1 at 18 rpm, ideal for heavy-duty cutting conditions.   *1：GV-1600 / GV-2000 series

The super rigidity, high rotation accuracy cross roller bearing can sustain radial, axial and torque compound loads to ensure machining accuracy under long-term heavy work loads and extend the service life of the spindle.

POWERFUL MACHINING CAPACITY

Optional live tooling spindle and C-axis can provide turning, milling, drilling, tapping and other complex processing capacity.
This can increase production efficiency, also can avoid setting error when parts moving between machines.

Live Tooling Spindle

High power FANUC spindle motor and two-step gear box design, max. turning speed 2,400 rpm can provide high torque output in low speed to satisfy heavy cutting request.

High accuracy, high rigidity P4 class NN type dual roller bearing design, this can bear high load from axial and radial, even spindle working long time can also keep best accuracy.

Live Tooling Spindle Output

Ultimate C-axis Spindle

Cf–axis is driven by ultra high resolution servo motor. It is adopted with worm gear drive system for high accuracy transmission and easy backlash adjustment. The indexing accuracy is up to 0.001°.

Standard disk brake system provide quick reacting and adequate locking force to satisfy rigid request when heavy cutting.

OPTIMIZED EQUIPMENT

ATC System

High reliable BT50 12 / 16 / 24 T umbrella type ATC system which providing 50 kg maximum tool weight and 360 kg maximum magazine loading capability.

Fully enclosed ATC door only opened when tool change. ATC won't be damaged by cutting chips that can make sure tool changing reliability.
