Heavier duty VMCs tailored to user needs
Having the advantage of a wide cast iron column and base, VMCs offer a choice of table sizes, spindle options and tool changer specifications for heavier duty milling.
Having the advantage of a wide cast iron column and base to carry its 35mm width linear ways spanned at 560mm on the Y-axis, the latest Dugard Eagle - 660 and 850 vertical machining centres have the ideal platform to perform heavier duty milling operations The two models of Eagle machine now available from C Dugard of Hove in Sussex are identical in features and benefits but differentiated in table length and the stroke of the X-axis

Travelling column VMC has dual-pallet indexing
Vertical machining centre with a travelling column design and integrated rotary dual-pallet indexing system provides higher levels of productivity and output and efficient workpiece loading/unloading.
Wide range of CNC machines will suit all tastes
High speed lathes, as well as vertical and horizontal machining centres, to suit all tastes, will be exhibited at Mach 2002 by C Dugard.
The Eagle 660 is designated from its X-axis stroke of 660mm while the Eagle 850 has the same axis travel distance increased to 850mm.
The table is 810mm by 510mm on the Eagle 660 and 1000mm by 510mm on the larger 850 machine, all set on a floor space requirement of just 2m by 2m.
One of the key advantages to customers wanting to almost tailor these machines to their needs and capitalise on the rigidity of build are the options available.

High-speed vertical turning and machining centres offering production times that are significantly faster than current machines can achieve - with up to 96m/min rapids - cost under GBP 50,000.
Double-acting ballscrew cuts machine downtime
Very fast-moving mill-tap centres, zippy machining centres and a very nippy pick-up spindle vertical turning lathe are the results of applying a double-acting ballscrew axis drive.
For instance, there are six variants of spindle, two further types of tool changer in addition to the standard 20 position carousel type unit and four choices of control including Heidenhain in addition to Fanuc's OiM series that is the standard fitment.
All spindle options feature a BT40, CT40 or DIN40 taper and coolant jacket to dissipate heat from the bearing assembly that has a large 70mm inner diameter front bearing with ABEC Class 7 super high precision angular contact ball bearings.
A choice from the standard 11kW belt-driven 8,000 rev/min specification covers 10,000 or 12,000 rev/min options and either 7.5kW 12,000 rev/min or 11kW 15,000 rev/min direct drive systems.
There is also a ZF gearbox version of the 8,000 rev/min spindle.
The toolchange system has 20 carousel positions as standard however, as an option a random operation side-arm system can be specified with either a 24 station twin-arm changer magazine or a 32-station chain type unit.
Control system preferences are fully catered for with the Fanuc OiM series fitted as standard.
However, Heidenhain TNC 410M or iTNC 530 controls can be specified or Fanuc OiMT-A with data server, Fanuc 18i MB or Siemens 802D/810D with ShopMill software.
Axis travels are 520mm in Y and 510mm in Z with rapid traverse rates of 30m/min in X and Y and 24m/min in Z, driven by pretensioned 40mm ballscrews to a positioning accuracy of +0.004mm.
Repeatability is +0.003mm.
Linear scale positioning is also available to meet greater accuracy requirements.
As standard, coolant system and rear chip flushing is included, while further options include an oil skimmer, dual screw-type chip conveyors, spindle chiller, fourth axis-rotary table, through the spindle coolant and automatic tool length measurement. Request a free brochure from C Dugard ...
