Bevel cutting head features high-accuracy positioning - TheFabricator.com

ESAB Cutting Systems has updated its line of CNC plasma bevel cutting systems with the new VBA Global PRO bevel head for high-accuracy plasma bevel cutting on steel plate. It features a high-accuracy positioning system with dual linear rail lifter, digital AC drives, and heavy-duty gearboxes.

The system carries the PT-36 plasma torch, which delivers precision plasma cut quality and plasma marking with the same consumables. The station features pneumatically balanced tool-tip sensing, encoder height for optimizing hole quality, and magnetic breakaway crash protection.

The rotation and tilt system delivers torch-positioning accuracy and repeatability, the manufacturer states. A tactile sensor can be used during bevel cutting to maintain precise cutting height above the plate, regardless of electrode wear, plate warping, scrap position, or table condition. Bevel cuts also can be made with arc voltage height control.

The pneumatically balanced magnetic breakaway torch holder allows accurate initial height sensing while providing a sturdy torch mount during cutting. It also offers breakaway crash protection in case of a tipped part.
