Twin-turret turning center features fully programmable tailstock
FLORENCE, Ky., October 18, 2016 – The Mazak HQR-250MY+Tailstock Multi-Tasking Turning Center delivers faster cycle times and more efficiency than other comparable machines thanks to its advanced Y-axis machining capability, twin-turrets, fully programmable tailstock and leading edge MAZATROL SmoothG CNC. The machine provides shops with unequaled part-processing opportunities, including enhanced DONE IN ONE® capabilities.
For fast and reliable production, the HQR-250MY+Tailstock can completely machine parts from bar slug and/or bar material in single setups. Also, the balanced cutting of the machine’s upper and lower turrets, together with Y-axis machining, ensures high part throughput with simultaneous turning and milling operations on the same part.
Because the twin turrets operate independently or together on the same workpiece, the machine can process two different features on a workpiece simultaneously, or follow a balanced strategy where two tools work together on the same workpiece feature.
In cases where the part configuration permits, balanced machining can potentially remove up to 25 percent of the cycle time.
Both the upper and lower turrets accommodate 12 tools (16 tools optional) each and have 4" (102 mm) Y-axis travel capability for off-centerline operations. And unlike other comparable machines that offer only upper-turret live tooling, both turrets on the HQR-250MY+Tailstock accommodate rotary tools and at any tool position. Rotary tool spindles on each turret deliver 6,000 rpm and 7.5 hp for milling and drilling multi-tasking functionality.
For perfect part support, the HQR-250MY+Tailstock’s MT#4 servo-driven tailstock, with brake, delivers a maximum thrust of 225 to 1,574 ft-lb (1-7 kN) programmable in increments of 22.4 ft-lb (0.1 kN). Plus, the thrust amount can be adjusted while the tailstock is engaged. To help shorten non-cut time, the tailstock rapid traverses at speeds up to 315 ipm (8 m/min).
Large diameter bearings support the machine’s spindle for high rigidity. The spindle features a 10" (254 mm) chuck, 3.1" (78.740 mm) bar capacity and 35-hp integral spindle motor that provides a maximum 4,000-rpm speed. With full CNC C-axis control, the spindle positions and contours with indexing increments of 0.0001 degrees.
The machine comes equipped with the new MAZATROL SmoothG CNC that makes it fast and easy to generate programs for high-speed multi-axis processing of complex parts through off-centerline machining as well as angled drilling, milling and tapping. For the HQR-250MY+Tailstock, the control also includes hobbing software.
Through the SMOOTH TECHNOLOGY platform, the MAZATROL SmoothG CNC offers programming with MAZATROL and/or EIA. There are also several other advanced programming functions.
For continuous unmanned operations, the HQR-250MSY easily integrates with an optional bar feeder and unloader or robot loader/unloader.
