Mazak’s Quick Turn-250MSY turning center features several new productivity-enhancing features, including a direct-drive turret design; higher-torque main spindle; faster, more powerful milling spindle; and new Mazatrol SmoothG CNC.

The 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. It accepts both VDI and bolt-on tooling. The turret’s standard direct-drive rotary tool spindle is now 10-hp and 6,000 rpm. This faster rotary spindle provides 52 foot-pounds of torque, essentially double of what was possible with the previous version, the company says. A 10,000-rpm option is available.

The turning center’s headstock features a 10" main chuck mounted on a 35-hp, 4,000-rpm integrated spindle motor for heavy-duty metal removal. Torque output also has been increased to almost 30 foot-pounds to handle tough materials. The main turning spindle also serves as a C axis that is programmable in 0.0001-degree increments to accurately position parts for square facing and slotting cuts and 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 allows the turning center to machine small-diameter workpieces with speed and accuracy.
