Mazak HQR-250MSY - High productivity 2 spindle and 2 turret CNC turning center

The Mazak HQR-250MSY multi-tasking turning center features a highly productive twin-spindle, twin-turret configuration for unequalled part processing opportunities and high-volume throughput.

Application: General industrial component     |     Material:1045

With its upper turret with rotary tool milling (M), second spindle (S) and Y-axis capabilities (Y), the Mazak HQR-250MSY delivers Done In One part-processing opportunities and high-volume throughput.

The twin-spindle, twin-turret configuration of the Mazak HQR-250MSY can easily complete machining from slug and/or bar material in a single setup. Furthermore, the balanced cutting of the upper and lower turrets promotes high part throughput. By operating together or separately, the twin opposed turning spindles allow a single part to be machined on all surfaces through a coordinated hand-off between spindles. Alternately, two different parts can be machined simultaneously on one machine. In cases where the part configuration permits, balanced machining can potentially remove up to 25% of the cycle time.

The spindles are supported by large-diameter bearings for high spindle rigidity. The main spindle features a 10" chuck, 3.58" spindle bore and 35-hp integral spindle motor that provides a maximum speed of 4,000 rpm. The second spindle has an 8" chuck, optional 3.58” spindle bore and a 35 hp integral spindle motor that offers a 4,000-rpm top speed. Both have full C-axis control for part positioning and contouring with indexing increments of 0.0001 degrees.

Both the upper and lower turrets accommodate 12 tools each and have 4" Y-axis travel capability for off-centerline operations – for additional flexibility, turrets may be expanded to 16 positions each. Rotary tool spindles on each turret deliver 6,000 rpm and 7.5 hp for milling and drilling functionality.

The Mazak HQR-250MSY comes equipped with the Mazatrol SmoothG CNC, which makes it easy to generate programs for processing high-production complex parts through offcenterline machining as well as angled drilling, milling and tapping. Through its Smooth Technology platform, the Mazatrol SmoothG offers several advanced programming functions, including Smooth Corner Control, which reduces vibrations and shortens machining cycle times through cutter path adjustments made when machining into corners, and Intelligent Pocket Milling, which engages a high-efficiency toolpath when milling out part cavities.

For continuous unmanned operations, the Mazak HQR-250MSY easily integrates with an optional bar feeder and unloader or robot loader/unloader.
