Pick-up adapted to shafts
The horizontal cross slide carries both the motor spindle and the NC tailstock; tailstock and steady rests move under NC. No loader or robot is needed, a conveyor belt is enough; NC shuttle optional.

Frequently asked questions
What is the difference between the pick-up and the gantry-loaded AS?
On the pick-up version (AS 400 / AS 650) the single spindle picks up the part itself; Ø 160 mm turning, 215 mm chuck, only a conveyor belt required. The gantry version (AS 800) has a main spindle with tailstock or counter spindle, 4 axes with two turrets, Ø 320 mm turning, a 400 mm chuck and workpieces up to 800 mm long.
How does the AS 400 differ from the AS 650?
The AS 650 has a 2,400 mm Z stroke (AS 400: 1,130 mm), 990 mm between centres (740 mm) and a linear-motor Z axis at 100 m/min (60 m/min). The external grinding unit is an option only on the AS 650.
What are typical cycle times?
Manufacturer examples: hardened drive bevel gear 60 s and input shaft 40 s (rotational turning, hard turning, grinding); end machining of a soft main shaft in one set-up 300 s; complete machining of an input/main/output shaft in one set-up 90 s depending on scope.
