Tool holder: HSK-A 50, 63, 80, 100 various applications with preset tools; universal unit; manual tool clamp Models DB, DC Drive technology: Motor Spindle (water cooled) Motor power (max.): 20 … 31 kW (max. 7000 rpm) Spindle torque: 27 … 425 Nm (max.) Tool holder: HSK-A 50, 63, 80, 100 very precise and stiff unit (small space) with coolant spray at the spindle head and – as an option – an internal coolant supply through the tool; manual tool clamp (DB); (automatic tool clamp (DC); various applications (like turning, heavy-duty facing, deep hole drilling, boring of pipes and hollow shafts, etc.) The ARLA® Spindle Units DX with facing head are innovative models with an integrated motor spindle and an integrated facing head. The facing heads are – according to customer's requirements – available as single slide, or double slide heads optionally counterweighted to support higher spindle speeds. The facing head concept enables the machining of a fixed workpiece which could only be done by turning machines. Due to the new ARLA technology this concept is much better, more accurate and flexible so that the machining process becomes significantly more productive.
