Pick-up spindle lathe has hexapod features
A new, hanging-spindle, vertical turning lathe (VTL) has been introduced by Index on which the spindle head is able to move freely in three dimensional space.
Having a Meehanite cast iron, 45 deg slant-bed construction, the 22 tonne MHP260/3000 has a 900mm turning diameter and can accommodate components up to 3m long between chuck and servo-driven, programmable tailstock, which features a hydraulic quill with 150 mm stroke.
The spindle is rated at 45kW / 1,250 rev/min and delivers 235Nm of torque through a 1:4 ratio gearbox.
Eight 60VDI tools are resident in the turret, all stations being powered by a 7.5kW, 3,000 rev/min motor.
Control is by Siemens 840D CNC with integrated, double redundancy safety system and 'Shopturn' shop floor programming.
Each subsequent lathe will be built to order and can be tailored to the requirements of the user, including selection of the control.
For example, the next machine has already been ordered and will have 1100mm swing over the bed, 1000mm turning diameter, 2000mm turning length, no tailstock and a 12-station, 60VDI turret.
Many different options may be selected including Heidenhain linear glass scales in X and Z for enhanced accuracy, a three-roller steady rest for components ranging from 200 to 500mm in diameter, a Renishaw infrared probe mounted in the turret for component measurement, vacuum chucking and interface, and hydraulic power chuck.
