Multi-function lathes have tailored
specification
Flat bed lathes have a list of options that read like an 'upmarket German car brochure' enabling the potential user to tailor the specification to best carry out its designated task.
There are 32 basic models in the Dugard Eagle range of Multi-Function CNC lathes with a swing ranging from 560mm to 1100mm designated by the model number and between centre dimensions which can be up to 6000mm In addition these, Fanuc or Siemens controlled flat bed lathes have a list of options that read like an upmarket German car brochure enabling the potential user to tailor the specification to best carry out its designated task

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.
Available from C Dugard of Hove, Sussex, these fully programmable universal lathes are split into two categories, the HD 560, 660, 660A and 720 and the larger capacity HD 830, 970 and 1100.
The machines are all constructed on a wide, flat, hardened and ground cast iron bed with three vee slideways.
High quality proprietary components are common throughout the range from mainstream suppliers such as NSK and Sauter with quality slide-aside guarding having large visual panels.

Low-cost turning and MCs cost under GBP 50,000
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.
Control is via either Fanuc 21i-TB with Manual Guide Assist or Siemens 840D with Manual Turn using electronic handwheels and digital readout, with the facility of macro assist programming and full CNC cycle repeat for batchwork.
There is even a choice of control mounting either by pendent or the unit being carried on an independent carriage mounted in front of the guarding.
All machines in the range provide the option of Multifix C manual, quick-change toolholder or a fully programmable Sauter eight-station VDI turret.
The HD 560 and 660 have a 105 mm spindle bore which is increased on the HD 660A and 720 to 140 mm diameter.
Between centre dimensions are 1000mm, 2000mm, 3000mm and 4000mm with the swing designated by the model number.
Up to 2.2 tonnes can be held between centres without steadies and the two-speed gearbox driven headstocks powered by high torque 15kW motors have top speeds of 2,300 rev/min or 1,850 rev/min.
The larger HD 830, HD 970 and HD 1100 versions designate the swing with each machine being available with bed length in 1,000 mm increments between 2000mm and 6000mm.
Spindle power is 26kW and spindle bores from 140mm diameter to 450mm are available.
Eight position Sauter turrets are also available in VDI 50 or VDI 60 as an option to the standard Multifix DI quick-change toolpost.
Linear scale measuring is also available on the X axis and longitudinal Z axis for higher accuracy positioning.
Typical of the C Dugard attention to detail in the Eagle range of machines is an extended neck to the extra large optional tailstock quills of 125mm or 140mm diameter.
This gives vastly improved access for machining close to the tailstock centre.
Included in the options listings are nine steady and three following rests plus three hydraulic self-centre types, 14 three and four jaw chucks and hydraulic chucks of different sizes and types.
There are six different swarf conveyors available, hydraulic tailstocks, automatic spindle speed change and a whole host of accessories. Request a free brochure from C Dugard ...
