The HQR-250MSY multitasking turning center is said to complete machining from slug and/or bar material in a single setup.

With its upper turret with rotary tool milling, second spindle and Y-axis capabilities, the HQR-250MSY multitasking turning center from Mazak Corp. delivers part processing and high-volume throughput. The twin-spindle, twin-turret configuration is said to complete machining from slug and/or bar material in a single setup.

The balanced cutting of the upper and lower turrets promotes part throughput. By operating together or separately, the twin opposed turning spindles enable a single part to be machined on all surfaces through a coordinated “hand-off” between spindles. Alternately, two different parts can be machined simultaneously. The spindles are supported by large-diameter bearings for high-spindle rigidity. The main spindle features a 10" chuck, 3.58" spindle bore and a 35-hp integral spindle motor that provides a maximum 4,000-rpm speed. The second spindle has an 8" chuck, 2.55" spindle bore and a 30-hp integral spindle motor with a 5,000-rpm top speed. Both have full CNC C-axis control for part positioning and contouring with indexing increments of 0.0001 degree.

Both the upper and lower turrets accommodate 12 tools (24 tools as an optional feature) each and have 4" Y-axis travel capability for off-centerline operations. Rotary tool spindles on each turret deliver 6,000 rpm and 7.5 hp for milling and drilling multitasking functionality. Additionally, the machine is said to optimize part throughput with the use of factory unloading that brings finished workpieces as large as 3" x 10" to the outside of the machining area without interrupting the machining cycle. For continuous unmanned operations, the machine can integrate with an optional bar feeder and unloader or robot loader/unloader.
