Mikron is claiming a breakthrough in high-speed machining for its new XSM 400, which reaches the highest levels yet achieved for acceleration, feed rates and control performance.

The XSM 400 breaks into the new territory of ultra-high-speed machining with acceleration of 2.5G, a maximum feed rate of 80m/min and spindle speeds of 30,000, 42,000 and 60,000rev/min.

The combination of optimal cutting speed, automation and the highest levels of accuracy and surface quality, allow manufacturers to slash more off lead-in times, while the XSM 400 can handle materials from +62 HRC steel to plastics.

Low cutting forces also give it the versatility to handle thin-walled parts and small milling diameters.

THE XSM 400, which incorporates the best design features from its HSM 4/6/800 stablemates, draws on the ground-breaking Cyclone expert control system developed by Mikron for its speed and accuracy.

Based on the Heidenhain Atek system, which made its debut at EMO 2001, the Cyclone lies at the heart of the new machine's abilities.

Cyclone is the first system in the world that can detect contour changes in the programme and can automatically adjust the XSM's dynamic parameters during machining, applying accuracy only at the points and times that it is needed, thus producing even greater time savings.

Cyclone gives the ability to tune up milling programmes by using only four parameters on a graphically assisted desktop.

The operator can tailor the Cyclone's abilities to best suit the demands of a particular task, by setting speed, accuracy or surface finish as the priority or a combination of these machine performance settings.

The operator can also add extra settings over time, building up an instantly accessible performance bank based on the experience of past work.

Other features of the Cyclone include algorithm compensators that make automatic adjustments to allow for displacements caused by temperature rises during machining and the effects of centrifugal forces in the bearing of the spindle nose, helping to ensure even higher accuracy.

With work area of 400 x 450 x 350mm, the XSM will handle workpieces up to 200kg and incorporates an automatic tool changer with 18, 36 or 68 tool options, while a pallet changer can be added for "lights out" operation.
