MAG Series of HMCs with 5 axes draws on long lineage
Units are based on four decades of use.
Some 40 years after the first Hüller Hille NC nb-h 70 machining centre and the follow-on nb-h 90 to nb-h 260 series, MAG IAS has announced that it is now offering a complete series of eight NBH-type horizontal machining centres with pallet sizes of 500 x 500mm to 1,000 x 1,250mm.

The company said a swivel head is available starting from size NBH 630 for the machining of complex workpieces in one setting, multi-sided machining, drilling or surface machining in different angles and free-form surfaces in tool and mould making and in the aerospace industry. The swivel axis – from the range of 0 degrees (= horizontal spindle position) to 225 degrees (180 degrees = vertical spindle position) – and the NC rotary table can be driven without backlash by a powerful gear, MAG explained. This design is said to provide maximum torque for positioning and simultaneous operation.
According to the manufacturer, a further important feature of the new machining centres is 5-axis precision. For this purpose, a thermally stable machine is necessary. Other features on the units include cooled servo motors, ball assemblies and gears as well as coolant temperature control, the manufacturer noted.
