Mazak Corp.’s QTU-200MY turning center features a main turning spindle, tool turret with rotary milling spindle, Mazak’s Mazatrol SmoothC control and Y-axis off-centerline capabilities for versatility. The machine’s headstock incorporates a built-in spindle/motor design.

The A2-6, 20-hp (15 kW)(15 percent ED) main turning spindle provides speeds from 35 rpm up to 6,000 rpm with 90 foot-pounds of torque for heavy-duty metal removal, the company says. Its spindle bore diameter of 2.4” (61 mm) accommodates a maximum bar diameter of 2” (42 mm).

The main turning spindle also serves as a full 360-degree C axis that indexes in 0.001- degree increments. According to the company, it is a full-function CNC programmable axis that positions parts for complex and prismatic machining along with 3D contouring.

Additionally, the turning center is outfitted with a 12-position, integral-motor turret that uses a roller gear cam drive system for digital indexing as well as expandability. The turret eliminates the need for curvic/index couplings and with the use of tandem tooling allows the number of tool positions to be expanded, the company says.
