Geared up and dynamic

The new model NBH 500+ adds a pallet size 500 machine, completing MAG’s NBH series of highly productive horizontal machining centers. Profiting from the modular design, this lower end size machine covers the capacities and benefits of the former NBH 95/135 models and the cost optimized NBH 5/5+. As a universally applicable allrounder, the configurations feature a wide variety of motor and geared spindles, covering the speeds and torque ranges for a vast range of applications. The choice of tool magazines adds to this universality with production proven disc-, chain- and rack-type magazines. The machining centers including 180 deg palette changer and tool magazine is designed as single, compact transport unit. This guarantees easy installation and setup for a quick start of production.
