Power density
Main spindle
The ABC's main spindle utilizes a high-torque, hollow-shaft synchronous motor with patented headstock air cooling, delivering 20 kW of power at 100% DC. A low air overpressure in the headstock prevents ingress femulsion, while the rotor, end windings and stator are cooled directly. The spindle features short acceleration times, no mechanical transmission elements, low rotating masses maximum smoothness and high torsional stiffness.
Synchronous spindle
Offering a maximum speed of 4,500 rpm, the ABC's synchronous spindle provides collet clamping of up to 42 mm or with 90 mm chuck diameter, and also allows internal clamping. The spindle is equipped with an alignment and indexing unit as standard. The synchronous spindle is driven separately from the central drive, using a spur gear on a dedicated turret station.
The principle of W-slots
The patented INDEX W-serration on the tool holders and turret ensures high repeatability when changing tools.
