This will be reflected in the Hurco exhibits at MACH 2010, which will see the introduction of six new vertical machining centres. DCX22 Exemplifying Hurco's progression into the realm of large machining centres, the new twin column, bridge type DCX22 will dominate the stand, despite being the smaller of two models introduced last year. Available in 40 taper and 50 taper versions, the DCX 22-40 will be on show. According to Hurco, the construction has advantages over gantry type and C-frame machines in that it has superior thermal stability for higher accuracy machining, and allows heavier table loads and a larger Y-axis travel with no loss of rigidity. Large components can therefore be produced to tight tolerances, such as dies, moulds and parts for the aerospace and energy sectors. The fixed rail design of the DCX 22-40 offers XYZ travels of 2,200mm x 1,700mm x 750mm with 24m/minute rapids and a 2,100mm by 1,600mm pallet. The 40 taper spindle with 18kW (optionally 26kW) of peak power is mounted in a vertical ram of box construction for maximum cutting capability and rigidity. There are 8,000rpm, 10,000rpm and 15,000rpm spindle options. The 40 station, swing arm toolchanger keeps the carousel clear of swarf and maximises the working envelope. All DCX machines are fitted with Hurco's WinMax twin screen control system, allowing complex 2D jobs to be programmed at the machine quickly and easily. VMX60SR The VMX-SR range of 5-axis machining centres is designed with a B-axis swivel head and a horizontal rotary C-axis table to tackle complex, multi-sided parts. A special version of the manufacturer's proprietary WinMax 5-axis control software streamlines set-up, simplifies programming and is compatible with more CAM programs than before. Swept Surface software is said to reduce programming time by as much as 80%. Heavy-duty digital servo drives, large ballscrews and substantial linear rails increase machining accuracy and provide excellent surface finish. Specification of the nine tonne, 40 taper VMX60SR that will be exhibited includes X Y Z axis travels of 1,525mm x 660mm x 610 mm, maximum component weight capacity of the rotary table of 500kg, peak spindle motor power of 36kW, 118Nm torque at 2,900rpm, and 30m/minute rapid traverse in X and Y, 20m/minute in Z. VMX42U Another new 40-taper, 5-axis machine, launched at Hurco's open house last December but new to MACH, is the VMX42U with integral trunnion table. The VMX42U combines reliability and performance with advanced 5-axis technology, streamlining the production of multi-faceted, complex parts. The WinMax software includes 5-sided conversational programming and a smoothing algorithm that produces excellent surface finishes, minimising the need for hand polishing of moulds. With XYZ travels of 1,067mm x 610mm x 520mm, the machine can accommodate workpieces weighing up to 250kg. Two spindle options are 12,000rpm and 15,000rpm – peak power being 24kW. Rapids are 35m/minute in X and Y, 30m/minute in Z. VM20, VM10U, VM10 Hurco has introduced a major upgrade of its compact footprint VM range of vertical machining centres, but has not increased pricing. Improvements include adding around 50mm to the Y and Z axes and providing a 10,000rpm spindle as standard. Designated VM10, VM20 and VM30, the new 3-axis models also have a faster, electronic, 20 station swing arm toolchanger to minimise non-cutting time and further improve productivity and reliability. Rapid traverses are now 24m/minute in all axes. The two smaller models, VM10 and VM20, will be demonstrated at MACH together with a ‘U' version of the former complete with appropriate WinMax software to provide 5-axis machining capability using the rotary table/trunnion configuration. Dave Waghorn describes this machine as one of the most compact and cost-effective 5-axis solutions on the market at the moment. VMX24t The only Hurco machining centre at this year's exhibition that appeared at MACH 2008 will be the VMX24t with 610mm x 508mm x 610mm axis travels and twin screen Ultimax control system. It is the smallest in a range of seven VMX models that form the backbone of the company's 3-axis vertical-spindle machining centres. Hurco
