As these are heavy duty operations requiring high speeds and feeds, the WT 24 features an extremely robust design, while only requiring a small foot print which makes it ideal for robot cells.
The WT uses Rexroth roller type linear guides and large 50mm diameter ballscrews, while the Royal A11 spindle is driven by a powerful Fanuc Alpha 40 digital spindle motor which has a continuous rating of 37 kW and a 30 minute rating of 45 kW.
The axes are fitted with Fanuc Alpha 22 servo motors which provide the thrust for fast acceleration, rapid traverse and heavy duty turning. Backlash free couplings fitted to the Rexroth ballscrews ensure long term working accuracy.
Special chucks, manufactured by Efamatic prevent any movement of the wheel during heavy cutting operations. As the material removal rates are extremely high, the working area has been designed to allow for free fall of the shavings onto screw type conveyors which the customer has requested.
This free flow of shavings is assisted by two high volume coolant pumps which flood the working area during cutting.
The Baruffaldi TB 320 VDI turret has a diameter 490 PCD which reduces tool interference, while through coolant is standard, and doors provide easy access for inspection, cleaning and maintenance.
