The constant demand to reduce manufacturing costs is reflected in Victor's new generation lathes Vturn II-16/20/23/26 where the aim has been minimized part throughput time. Whilst in addition providing options that will offer increased all-around performance to enhance machining processes. The new Vturn II lathes have a high degree of stability from one piece Meehanite casting which was developed through CAE design and has integral box slideways that absorb dampen stress and heat throughout the entire structure.
- Increased productivity
- Greater rapid feed rates 20/24m/min on X / Z axes redures turning cycle time.
- Accomplished by increased motor speed & power while maintaining high thrust force for the cutting tool.
- 0.2 second real turret indexing time by Servo-driven turret designed to unclamp and clamp during axis retraction and approach.
- 30 min. may be replaced by 15%, 15 min. or 20 min. according to Fanuc specification
- Hight performance drives on X and Z axes
- Improved ballscrew stiffness and axis thrust force by minimizing pitch.
- Pre-tensioned double anchored ballscrews allow heat absorption without displacement.
- Direct coupled high powered servo motors.
- Box slideways with auto forced lubrication
- Large bearing area to absorb cutting vibrations.
- Hand scraped wedge structure maintains trapped film of oil between slideway and undercarriage for smooth & even travel.
- Integral slideway allows even heat distribution.
- Fully programmable tailstock(or sub-spindle) for easy automation.
- Heavy body casting to soak up vibrations.
- Slideway mounted with hydraulic clamping.
- Fully programmable with turret "tow along" for tailstock body.
- Easy extension to install DDS sub-spingle with dual winding assures the best collinear accuracy without re-clamping.
- Single block cast bed
- Rectangular machine base guarantees the optimal structure stiffness to assure the rapid feed rate 24 m/min on the lathes with box slideways.
- Homogenous casting distribustes stress thru-out structure.
- Meehanite gray cast iron for optimum damping properties.
- Optimum ribbing determined by FEM to minimize distortion during operation.
- To ensure perfect alignment in the machine structure the bed is machined in a single set-up on a large five-face machining center.

Accuracy Upgrade by DDS Spindle For C-Axis!
Based on the popularity of our older Vturn series lathes, we have also introduced an Vturn II-16/20/23/23CV offering C-axis spindle and live tooling to allow for secondary operations such as milling and drilling to be completed on a single machine. The Vturn II lathes equipped with brake to ensure spindle is rigidly held during heavy operations offers a full C-axis spindle with 0.001° indexing through the full 360° of the workpieces.
- Servo-driven turret for faster indexing
- Fast tool indexing time 0.2 seconds using servo driven turret.
- Maximum milling speed of 3000rpm by servo motor maintains a near constant torque output over the complete speed range.
- 12 station VDI turret with 6 or 12 live tool pockets allows quick tool changeover with commercially available tool holders (by Duplomatic servo turrets or Sauter hydraulic turrets).
- Vturn II-23/26BCV with full C-axis capability sub-spindle is fitted with 12 station live tool pockets capable of back face machining.
- Optional Y axis VDI turret (Vturn II-26Y) with travel 55 mm can be installed for more sophisicated turning applications.
- Direct Drive Spindle (DDS) motor with Cs axis design
- The spindle motor is integrated in the spindle to eliminate the vibrations from the belt or gear drives. This improves the spindle run-out and leads to a greater surface finish and roundness.
- The integral unit has lower inertia than traditional drives to allow faster acceleration time and to improve overall efficiency.
- Dual winding DDS spindle (similar as a 2-step gearbox installed) offers extra torque output at low spindle speed than conventional belt-driven spindle.
- Angular encoder is installed as standard to assure the angular accuracy on the spindle.
- Oil cooling for DDS spindle with cast in cooling fins on headstock to minimize heat build-up in the motor.
- The headstock in a jacket of a constantly chilled oil coolant that prevents the headstock from reaching the elevated temperatures that causes thermal expansion and degrades precision.
- Optional subspindle and C-axis with live tooling
- C axis for both spindle and sub-spindle maximum the application range.
- DDS sub-spindle with dual winding assures the best collinear accuracy without re-clamping.
- Changeover time 3 seconds (P-P) from the main spindle to the sub-spindle.
- Single block cast bed
- Rectangular machine base guarantees the optimal structure stiffness to sustain the high rapid feed rate 20/24 (X/Z) m/min on the lathes with box slideways.
- Homogenous casting distributes stress thru-out structure.
- Meehanite gray cast iron for optimum damping properties.
- Optimum ribbing determined by FEM to minimize distortion during operation.
- To ensure perfect alignment in the machine structure the bed is machined in a single set-up on a large five-face machining center.
- Heavy body casting to absorb vibrations.
- Slideway mounted with hydraulic clamp.
- Fully programmable with turret "tow along" for tailstock body.
- 30 min. may be replaced by 15%, 15 min. or 20 min. according to Fanuc specification
