SUPER RIGIDITY VERTICAL TURNING CENTERS

WITH LEADING TECHNOLOGY AND HIGH QUALITY COMPONENTS, THE GVF SERIES CNC VERTICAL
TURNING CENTER COMBINES A SUPER RIGID RAM STRUCTURE AND HIGH TORQUE GEAR TYPE SPINDLE
DESIGN TO PROVIDE YOU WITH HEAVY CUTTING ABILITIES FOR LARGE SIZES THAT ARE SUPERIOR
TO COMPETITORS' MODELS IN THE AEROSPACE AND ENERGY INDUSTRY. PLUS, WITH THE OPTIONAL
LIVE TOOLING SPINDLE, CF-AXIS CONTROL, AND MULTI-PURPOSE MILLING HEADS, TURNING,
MILLING AND DRILLING APPLICATIONS MAY BE COMPLETED FOR BOTH END SURFACES AND
CYLINDRICAL SURFACE TO ACCOMPLISH DEMANDING TURNING APPLICATIONS OF TODAY AND TOMORROW.
• ENCLOSED SPLASHGUARDS KEEP CHIPS AND COOLANT CONTAINED FOR A SAFE,
CLEAN WORKING ENVIRONMENT.
• EXTRA WIDE DOOR ENABLES LARGE-SIZE WORK-PIECES TO BE LOADED ONTO THE WORK
TABLE WITH A CROWN BLOCK PROVIDING EASY LOADING AND UNLOADING OPERATIONS.

SUPER RIGID CONSTRUCTION
THE FIXED CROSS RAIL DESIGN IS A REINFORCED RIB COLUMN INTEGRATED WITH A CROSS RAIL
THAT DECREASES WEAR AND TEAR OR DAMAGE PROBLEMS, WHICH GREATLY INCREASES
THE RIGIDITY OF THE HEAD DRAMATICALLY ENHANCES THE ABILITY OF VIBRATION SUPPRESSION.

BY USING FINITE ELEMENT ANALYSIS (FEA), OPTIMAL REINFORCED RIBBINGS ARE DIRECTLY
CAST INTO THE BED AND COLUMN STRUCTURE. MECHANICAL RIGIDITY HAS BEEN INCREASED BY
MORE THAN 30% WHEN COMPARED TO CONVENTIONAL DESIGNS. THE GVF SERIES IS CAPABLE OF
PERFORMING SUPER HEAVY-DUTY TURNING AND MAINTAINING LONG-TERM SUPER HIGH PRECISION
ACCURACY. MORE RIGIDITY ALSO MEANS EXTENDED TOOL LIFE. THE SUPER RIGID BED AND
COLUMN AREA OF MEEHANITE CASTING. IT IS CAPABLE OF WITHSTANDING GREATER STRESS WITHOUT
DEFORMING AND PROVIDING MAXIMUM VIBRATION DAMPING.

1. DUAL COUNTERWEIGHT HYDRAULIC CYLINDER
Z-AXIS IS BALANCED WITH 2 SETS OF HYDRAULIC CYLINDER WEIGHTS TO MINIMIZE
THE WORKLOAD OF THE SERVO MOTOR AND EXTEND THE LIFETIME OF BALL SCREWS AND BEARINGS.
2. PRECISION GROUND BALL SCREWS
C3 CLASS HARDENED AND PRECISION GROUND BALL SCREWS ENSURE THE HIGHEST ACCURACY
AND DURABILITY IS POSSIBLE. PLUS, PRETENSION ON ALL AXES MINIMIZES THE THERMAL
DISTORTION.
3. DIRECT DRIVE SERVO MOTOR
THE AXIAL SYSTEM HAS AN AC SERVO MOTOR DIRECT DRIVE TO PROVIDE GREAT THRUST AND
FAST ACC./DEC. MOVEMENT. PLUS, IT EFFICIENTLY DECREASES MOTOR LOAD AND REDUCES
GENERATION OF HEAT WHILE MAINTAINING ULTIMATE PERFORMANCE AND ACCURACY.

4. LIVE TOOLING SPINDLE (OPTIONAL)
EQUIPPED WITH OPTIONAL LIVE TOOLING, IT CAN OPERATE AS A TURNING-MILLING MACHINE THAT
PROVIDES MULTIPLE MACHINING FUNCTIONS, SUCH AS TURNING, MILLING, DRILLING, AND TAPPING.

WORK-PIECE SPINDLE
THE WORK PIECE SPINDLE USES A HIGH-TORQUE 2-SPEED GEAR BOX MATED WITH A FANUC ΑI
SERIES SPINDLE MOTOR TO PROVIDE 23,900 N-M (17,625 LB-FT) EXTRA-LARGE TORQUE OUTPUT
ON THE LOW-SPEED ZONE AND SATISFY DIFFERENT MACHINING REQUIREMENTS.

THE RIGID, CROSS-ROLLER SPINDLE BEARINGS CAN SUSTAIN RADIAL, AXIAL, AND HIGH TORQUE
LOADS WHILE MAINTAINING PRECISION - EVEN WHEN THE TABLE HAS BEEN CARRYING A
MAXIMUM LOAD FOR A LONG PERIOD.
