Quicktech S42 ATM

The Quicktech S42 ATM is a twin-spindle bar machine built around a B-axis tool spindle with an automatic tool changer: 42 mm (1.7 in) bar capacity on both spindles, an HSK-T40 tool spindle that runs to 12,000 rpm, and a 24-station magazine. That layout sets it apart from the rest of the maker's range, where milling is done by gear-driven live tools on a gang slide or a turret.

Both work spindles carry an ISO(DIN) A2-5 nose and run to 6,000 rpm. The main spindle is rated 11 kW (14.8 hp) with a 43 mm (1.7 in) bore. The sub-spindle is a built-in unit of 3.7 kW (5.0 hp) with a 33 mm (1.3 in) bore, so the second side of the part is meant for lighter cuts than the first. Turning length depends on the operation: the table gives 350 mm (13.8 in) for OD turning but 140 mm (5.5 in) for drilling on the main spindle, and 230 mm (9.1 in) against 55 mm (2.2 in) on the sub-spindle.

The tool spindle is a built-in motor of 10 kW (13.4 hp) and swings through a B axis of 190° = ±95°, which is what allows angled holes and faces without special holders. A tool change takes 1.3 sec, and the magazine accepts tools of up to 3 kg (7 lb). Next to the tool spindle sits a small gantry block with 6 positions for ER20 / Ø20 mm drill holders. Z travel is 400 mm (15.7 in) on the first axis group and 510 mm (20.1 in) on the second.

Quicktech presents the S42 as a machine for medical parts, naming titanium, chrome and stainless steel and one-process manufacturing. The control is a Mitsubishi M830S. Coolant is supplied at 5 bar + 25 bar from a 240 L tank. Two rows of the maker's tool-magazine table, maximum tool diameter and maximum tool length, are printed without a unit, so confirm those limits with Quicktech before planning long or wide tools.
