The new QTU-200MY turning center from MAZAK offers shops of all sizes ease of use, cost-effectiveness, and unmatched productivity. The space-saving machine features a main turning spindle, tool turret with rotary milling spindle, Mazak’s new Mazatrol SmoothC control, and Y-axis off-centerline capabilities for high versatility paired with all the benefits of multi-tasking part processing.
The machine’s headstock incorporates Mazak’s (built-in) spindle/motor design that eliminates the need for belts or pulleys for zero backlash or any belt stick/slip. The A2-6, 20-hp (15 kW)(15% ED) main turning spindle provides speeds from 35 rpm up to 6,000 rpm with 90 ft-lb of torque for heavy-duty metal removal. 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. It is a full-function CNC programmable axis that accurately positions parts for complex and prismatic machining along with 3D contouring.
Additionally, the QTU-200MY is outfitted with a 12-position, integral-motor turret that uses a roller gear cam drive system for smooth, high-speed, high-accuracy digital indexing as well as expandability. The innovative turret eliminates the need for curvic/index couplings and with the use of tandem tooling, allows the number of tool positions to be expanded. This is possible because it indexes digitally to any position without changes to the turret housing. And once in position, an integral hydraulic clamping system ensures maximum rigidity.
The turret’s rotary tool spindle delivers 4,500 rpm (standard) and 6,000 rpm (optional) to perform milling, drilling and tapping operations. The standard mill spindle provides 34.7 ft-lb of torque, while the optional higher speed version generates 17 ft-lb.
Because it features Y-axis off-centerline machining capability, the QTU-200MY uses Mazak’s special high-gain servo-control turret/feed-axis motion. The double-slide configuration delivers rigid, high-speed, precise positioning as well as smooth axis acceleration/deceleration. The machine’s X-axis ballscrews work in tandem with the Y- axis ballscrews that are inclined at 30 degrees to move the turret 3.94” (100 mm) in the Y axis.
The machine also features an NC servo-driven tailstock to enable automated processes. Learn more at www.mazakusa.com
