Kaast Machine Tools’ A-Turn SYMCNC Dual-Spindle Lathe offers a one-piece 30° slant-bed structural design. It is now available in four different swing lengths, including 22.5", 24", 26.75" (new for 2022) or 36", paired with any combination of three choices: S (Sub-spindle), Y (Y-axis) and M (live tooling).

The S model offers a sub-spindle, reportedly enabling the machine to process material almost continuously, running at 6,000 rpm, 7.5 kW (10 hp). With the 2022 updates to the A-Turn S, Kaast has added the option to increase the sub-spindle chuck diameter to 8" matched with 5,000 rpm. The footprints of these turning centers have also increased slightly, as the X-Axis travel has been increased due to customer demand.

The Y models feature Y-axis travel of ±50mm (±2"), increased from the previous Y-axis travel of ±40 mm (±1.57"). Adding the Y-axis enables complex turning and milling operations.

The M model refers to the live tooling option. The gear-driven BMT/VDI (Base Mount Tool/Verein Deutscher Ingenieure) live tool turret with 12 station is matched with a servo-mechanical 5 hp drive to turn up to 4,000 rpm.

All models utilize the FANUC 0i-T CNC control with an 8.4" color LCD monitor, 400 sets of registered part program numbers and 640 m part program memory. The standard four-bar coolant system is contained by the standard full enclosure and the three-color warning light enables the user to keep an eye on the machine while on the other side of the shop.
