Built on the body of Vturn-36 this slant bed lathe has been specifically developed for max. efficiency in Alloy wheel processing. Horizontal type lathe minimizes chip build up in wheel to prevent swarf marring the surface during operation. The machine's ample capacity allows wheels of up to 20" to be processed as standard Specific features have been added to improve machine efficiency, including strong coolant flow, Z axis telescopic cover, increased spindle power, special 3 finger chuck and chip conveyor, while the tailstock has been removed to reduce machine cost.
Efficient chip evacuation
High pressure coolant pump(6.5 bars) with 3 coolant pipes effectively washes hips away from the inside the wheel for coolant flow to prevent chip build-up within the wheel.
Large coolant tank gives a coolant capacity of 300 liters ensuring the machining is flooded with coolant during operation.
Telescopic cover for Z axis ensures no chips are trapped and prevents damage to the ballscrew. With 45 deg slant bed and a shower system located above the chuck cutting chips are quickly washed away from the machining area.
Special chip conveyor removing long spiral chips that are formed in wheel machining is offered as standard.
- Rigid structure for accurate wheel turning!
- Meehanite cast iron structure with hardened box slideways quickly dampens cutting vibrations for high accuracy even under heavy cutting.
- Hydraulic driven turret with cast iron body easily handles continuous interrupted cutting common in wheel turning.
- Spindle supported by heavy duty roller bearings to maintain tight runout even under heavy cutting.
- High performance for minimun wheel throughput time!
- Low pitched ballscrews are used to increase axis thrust force while Fanuc a30 spindle motor is offered as standard.
- This combination of high thrust axis drives and powerful spindle facilitates high metal removal rates for optimum productivity.
- As low rpm's are rarely used in wheel turning, a direct belt drive is used to reduce inertia of drive system and improve acceleration times.
- (Note: On Vturn-36W20 max speed is 2000rpm to improve torque output as high rpm not needed for large wheels.)
- Simple, easy wheel loading for maximun operator efficiency
- Automatic door opening & closing reduces operator workload particularly needed when continuously handling larger sized wheels.
- Special 3 finger hydraulic chuck clamped by standard foot switch is used to clamp the wheel rim, allowing simple yet accurate loading of wheels without fear of damage or distortion to the wheel.
