The latest generation of Miyano ABX-51/64SYY turn-mill centres to be launched at Citizen Machinery UK Open House 4-6 October 2011
Extending the variants of its top-of-the-range high productivity ABX turn-mill centres, Citizen Machinery UK has launched a 64 mm bar size, 6 inch chuck, twin-spindle, twin-turret machine with driven tools and + 40 mm of Y-axis cross feed and the ability to machine long shafts with a Z-axis travel of 721 mm.
The Miyano ABX-64SYY has a 15 kW main and 7.5 kW secondary spindle with automatic part transfer at 30 m/min rapid traverse. Two 12-station all-driven turrets each have 4.5 kW, 6,000 revs/min driven tool speed and up to 40 Nm of torque that will accommodate heavy duty milling sequences. Miyano’s own Stealth technology is also incorporated into the Fanuc control which enables on-site fine tuning of the machine to account for individual working environments or tailoring the machine performance to suit specific applications.
The development of the 11 tonne, heavy duty solid way machine has focused on improved flexibility to optimise any turn-milling operation and shorten cycle times with the two turrets being able to work at the same or both spindles to enhance its simultaneous cutting capability. The rigidity of the machine makes it an ideal platform to process difficult to machine materials and maintain a consistent performance and level of quality over extended periods especially when cycles involve considerable levels of milling or the demands of hard turning to replace separate grinding operations.
With the incorporation of Miyano’s close-loop Stealth technology and monitoring through strategic sensors, the machine can be fine-tuned to counter any effects or influence on a critical process requirement of thermal growth, for instance, during warm up and areas such as heat generated from the high power drive motors. Other factors such as the influence of high pressure coolant supply and heavy duty cutting involving extensive milling and drilling at high penetration rates that can produce greater volumes of swarf can also be accommodated.
Options available for the Miyano ABX-64SYY include high pressure coolant, parts-catcher and outfeed conveyor, a parts carrier for longer components and a range of automation packages. There are also software packs that include helical interpolation, rigid tapping, variable lead thread cutting and tool life management.
