Horizontal Machining Centre Is Both Powerful And Accurate

With experience gained from installing over 6,000 NH and NHX series horizontal machining centres, DMG Mori has introduced a further model, the NHX 6300 2nd Generation, with optimised design and a specification to suit customers' rising expectations. Users achieve short machining times with the new Fanuc control, while the CELOS app-based user interface enables consistent administration, documentation and visualisation of orders, processes and machine data.

Improved rigidity ensures highly productive cutting performance coupled with the precision required in demanding industries. In the aerospace sector, for example, up to 462 cm³ of titanium can be converted into chips every minute with an 80 mm diameter porcupine cutter in a powerMASTER series spindle with up to 1,413 Nm of torque. Even the standard spindle is rated at 12,000 rpm / 807 Nm, while a third version with 16,000 rpm is intended for customers needing higher speeds for even better surface finishes.

The 50 taper (optionally HSK-A100) horizontal-spindle machining centre achieves a rapid traverse rate of 60 m/min over its 1,050 x 900 x 1,030 mm axis travels. The NC rotary table is designed for pallets up to 630 x 630 mm. Workpiece height can be up to 1,300 mm and maximum table load is 1,500 kg. The standard wheel magazine has space for 60 tools, with optional magazines accommodating up to 330.

Having a stable bed and roller guideways in the orthogonal axes with 0.005 μm resolution linear encoders supplied by group company, Magnescale, the NHX 6300 2nd Generation is capable of even higher precision machining if optional control of coolant temperature provides enhanced thermal stability. Efficient chip removal and filtration of the coolant as standard enable reliable and continuous operation even when metal removal rates are high, such as when machining cylinder head castings and gearbox housings.

The twin-pallet design enables preparation of the next job while the previous component is being cut and allows the NHX 6300 2nd Generation to be connected to a linear pallet pool. Eight machines can be linked into a flexible manufacturing system with up to five set-up stations and space for a maximum of 99 machine pallets.
