Job shops will see productivity advantages with Mazak’s new Hyper Quadrex 200MSY turning center design. It features two high-performance spindles and upper and lower turrets, so it performs medium- to high-volume balanced cutting — unattended. With Mazak’s Done-In-One processing capability, the HQR 200MSY makes it possible to machine finished components in the 8-in. chuck range, from slugs, in one setup.
Also, Mazak explains that the balance cutting capability by the upper and lower turrets delivers “the ultimate part throughput, with Y-axis travels on both turrets ensuring the manufacture of a wider range of workpieces.” The 200 MSY is the latest addition to Mazak’s Hyper Quadrex family of two turret CNC turning centers. Among the 200MSY design features are twin opposed turning spindles with 5,000 rpm and 30 hp each, plus full C-axis CNC control for part positioning and contouring at a resolution of 0.0001°. It carries upper and lower, 12-station tool turrets (for fixed and rotating tools) and Y-axis machine travels for each turret, for off-the-centerline machining.
It will handle bar stock up to 2.55 in. in diameter, and it can mill on both turrets with 7.5 hp spindles.
The HQR 200MSY is outfitted with a RL100 gantry loader, so shops can maximize productivity for a wide range of applications without sacrificing floor space. The five-axis robot loader features a three-jaw double robot hand with sensors, and accommodates up to two workpieces that are 0.78 - 3.93 in. long and weigh up to 22 lb.
With its twin-turret / twin-spindle configuration the 200MSY brings various opportunities to shops. Main and secondary spindles can operate together or separately, so a single part can be machined on all surfaces by coordinating the transfer from one spindle to the other.
Or, two different parts can be machined simultaneously on the same machine. Because the twin turrets operate independently or together on the same part, it would be possible to machine two features of the part simultaneously; or to develop balanced machining strategies.
In balanced machining, two tools work together on the same feature if the design permits as much (eg., rough and finish turning, rough and finish milling; or, opposed feature drilling, tapping or boring using the Y-axes.) Mazak indicates that balanced machining can remove up to 25% of the cycle time, if the part configuration permits it.
