Mazak’s Quick Turn-250MSY turning center offers several productivity-enhancing features including a direct-drive turret design, a higher-torque main spindle, a faster, more powerful milling spindle, and the Mazatrol SmoothG CNC. This multitasking turning machine has two turning spindles, a rotary-tool milling spindle and Y-axis capabilities for single-setup part processing operations. The new 12-position, direct-drive turret eliminates the use of belts for improved part surface finishes and reduced maintenance, the company says. It accepts both VDI and bolt-on tooling.

The turret’s direct-drive rotary tool spindle runs at 10 hp and 6,000 rpm, providing 52 foot-pounds of torque. Speeds ranging to 10,000 rpm are available with an optional tooling package. The headstock features a 10" main chuck mounted on a 35-hp, 4,000-rpm integrated spindle motor for heavy metal removal. The main turning spindle also serves as a C axis programmable in 0.0001-degree increments to accurately position parts for square facing and slotting cuts as well as precisely drilled holes. The C-axis spindle is a full-function CNC-controlled axis for milling. A second 15-hp, 6,000-rpm turning spindle with a 6" chuck enables the machine to turn small-diameter workpieces with speed and accuracy.

The Mazatrol SmoothC and SmoothG CNCs offer EIA/ISO programming as well as conversational programming for generating complex drilling, milling or tapping programs. The controls also feature advanced hardware and software functions that promote productivity and performance accuracy in challenging part production operations. The SmoothG incorporates a variety of advanced programming functions for ease of use and high-speed, high-accuracy machining performance, such as High Gain Feed Forward Control, Fast Rotary Axis Speeds, Variable Acceleration Control and Intelligent Pocket Milling.

A variety of automation strategies can be integrated with the turning center, ranging from an automatic bar feeder to gantry robots for improved spindle utilization and a boost in productivity.
