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.
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 patented INDEX W-serration on the tool holders and turret ensures high repeatability when changing tools.

Join the most important events and stay up to date with the latest industry news
We invite you to an event dedicated to the latest technical solutions in the field of turning and grinding! Together with our top partners – BRUCKNER, BLOHM JUNG, INDEX, STUDER, WALTER EWAG – you will explore the most advanced technologies and attend live demonstrations that will address the needs and challenges you face in your activity.
Vă invităm la un nou eveniment anual exclusiv în care vom prezenta pentru a treia oară soluții de asigurare a calității împreună cu partenerul nostru ZEISS. Explorați împreună cu noi lumea metrologiei industriale ZEISS..
Și în acest an ne revedem la târgul Industry Expo & B2B Meeting Arad în data de 31.10.2024, începând cu ora 09:00. Suntem nerăbdători să împărtășim păreri și să găsim soluții pentru problemele cu care vă confruntați în procesul de producție.
Acest eveniment promite să fie o ocazie excelentă pentru a descoperi cele mai noi tehnici și metode de prelucrare care pot contribui seminificativ la cresterea productivității și la reducerea costurilor de producție.
