Megamill enables heavy-part machining

A DS Technology product story Edited by the Manufacturingtalk editorial team Aug 9, 2010

DS Technology has launched the Megamill moving-crossrail vertical-spindle machining centre for the manufacture of parts found throughout heavy engineering.

Despite the machine's large size, characterised by a choice of 10 X-axis travels from 7.5 to 30m and a Y-axis of 4 or 5m, linear rapid traverse rates of 30m/min are achieved.

Ideal for manufacturing parts such as big moulds and dies, power-generation components and aerostructures, the machine features a thermosymmetrical, fabricated steel ram of sturdy cross section.

It allows rigid, high-accuracy milling - even at the full Z-axis stroke, which is either 1.5 or 2m - meaning that it is no longer necessary to fixture a flat component to raise it from the table during machining.

The water-cooled spindle motor is rated at 52kW/1,200Nm and is located within the ram, together with the gearbox.

The front face of the ram incorporates a rotary platform, with indexing or continuous positioning, on which a choice of milling heads is mounted, enabling the Megamill to carry out a range of operations, from the machining of aluminium through to heavy metal-removal rates from steel.

Two 38kW, ISO 50 taper heads deliver up to 1,000Nm of torque and provide 4,000 and 6,000rpm maximum spindle speeds, respectively.

The former has a slim profile for accessing awkward areas, while the latter is a universal head on which the lower part carrying the tool rotates at 45deg to the upper element - which has continuous positioning in 360,000 angular increments.

The third is a fork head with electrospindle rated at 22kW/20,000rpm and has an HSK-63E taper for high-speed three-, four- or five-axis machining.

Chain magazines from 24 to 100 pockets are offered and automatic head change is optional.

Various coolant delivery systems are available, as are radio-based laser tool measuring and CCTV supervision of the machining area.

Control is by Siemens 840D or Heidenhain iTNC530.
