Bed millers offer plenty of power
Aimed at toolmakers, bed-type CNC millers apply full spindle power from 225 rev/min upwards for heavy duty milling of mould and tooling steels.
Following the appointment of Warwick Machine Tools as sole UK agent for the range of CNC bed-type milling machines manufactured by MTE, Spain, two new models have been introduced aimed primarily at the toolmaking industry Called Compact and Compact Plus, they both have cross and vertical traverses of 800mm, while the former offers 1.5m in X and the latter 2m

No cartridges allows EDMs to work long cycles
EDM die sinkers that can filter electrolyte without having to change any cartridges means that they are able to operate continuously over long periods when machining nickel alloy turbine parts.
Wire EDMs can cut wide and deep tapers
These EDM machines are believed to be the first on the market to cut taper angles, in submerged mode, up to +/-30 degrees over the full X and Y axes.
Maximum workpiece weight is 3 and 4.5 tonnes respectively.
The spindle speed range of 40 to 2,500 rpm, delivered by a 15kW (optionally 22kW) AC motor via a two-speed helical gearbox, makes the machine ideally suited to cutting mould and tool steels, especially as full power is available from 225 rpm.
Spindle taper is ISO50, suitable for heavy metal removal rates.
Cutting feed is up to 4 m/min and rapids of 10m/min ensure short non-machining times.
Slideways in all three axes are hardened and ground and coated with low-friction material.
Each servo drive acts through a pre-loaded double-nut ballscrew.
The ram incorporates 360mm wide, L-shaped guideways for maximum rigidity.
To increase the machines' versatility, a universal milling head with built-in hydro-mechanical tool clamping system is provided.
So too is hydraulic counterbalance of the vertical axis.
Direct measurement using linear scales which resolve to 0.001mm avoids the inherent inaccuracy of rotary encoders and allows positioning accuracy to better than 10 microns and repeatability to within 7 microns.
Notable is that either machine may be converted into a machining centre with the addition of a 12- or 20-station tool magazine and an automatic tool change mechanism which acts when the spindle is in the vertical orientation.
In addition, there are high speed cutting versions of both machines providing spindle speeds up to 12,000 rpm, cutting feeds to 12m/min and rapids of 15m/min.
Other options include a horizontal / vertical twin-spindle head, a vertical or horizontal rotary 4th axis and a rotating or swivelling 5th axis.
