Mills CNC, the exclusive distributor of DN Solutions’ and Zayer machine tools in the UK and Ireland, is introducing the second-generation DN Solutions’ DVF 5000 advanced simultaneous five-axis machining centres into the UK and Irish markets and they will be available from May. The new DVF 5000 series, successor to the earlier DVF 5000 range first introduced back in 2018, has raised the bar for ‘one-hit’ machining and delivers improved accuracies, faster processing speeds and greater machining flexibility.
Tony Dale, Mills CNC’s Group CEO, said: “If you are going to launch a new, next-generation range of machine tools into the market, you need to make sure that it is significantly better than its predecessor; especially if that predecessor was the most popular, best-selling simultaneous five-axis machining centre series on the market. But ‘hats off’ to DN Solutions, because that is exactly what it has achieved with the second-generation DVF 5000 machining centre range.
The new range of machines offer faster X, Y and Z-axis rapids (42m/min) and acceleration/deceleration rates (0.4g), combined with increased B and C-axis rotation speeds (25rev/min) and impressive tool-to-tool changeover times (1.3sec), deliver significant productivity gains – reducing part cycle times and work throughput.
Advanced spindle technologiesThe productivity improvements continue with the new series’ advanced spindle technologies too. Standard second-generation machines are equipped with a directly-coupled 18.5kW 15,000rev/min spindle – capable of processing a diverse range of materials in double-quick time. To increase machining capabilities, a built-in high-torque 30kW 15,000rev/min 230N-m or 37kW 20,000rev/min high-speed options are available.
Irrespective of the spindle type selected, all options feature advanced oil-cooling which, working in conjunction with strategically located sensors on/in the machines’ spindle head, column and bed, monitor thermal displacement throughout the machining process, automatically adjusting parameters to minimise the effects of thermal expansion and drift.
The utilisation of precision roller-type LM guideways and high-accuracy 0.0001 degree B- and C-axis rotational mechanisms, with the optional IKC (Intelligent Kinematic Compensation) system to monitor and adjust rotary axis errors, guarantees precision even over extended use and lengthy machining runs.
The DVF 5000 second-generation machines can handle larger workpieces than their predecessors; they feature 630mm diameter rotary-tilting tables that can accommodate workpieces up to 600mm in diameter and 500mm in height. With a 26% increase in table size, and an equally impressive 32% increase in the machining envelope available and a 20% increase in the X, Y and Z-axis travels, customers can be assured that they will never be ‘pushed for space’ with the new machines.
Furthermore, the larger work envelopes and extended travels enables the seamless integration of automated work load/unload systems. These can include DN Solutions’ tried and trusted compact AWC (automatic workpiece changer) easy-to-install automated systems to facilitate 24/7 unmanned and unattended operations.
The second-generation DVF 5000 range can be supplied with Fanuc, Siemens or Heidenhain CNC control systems – each boasting accelerated data and PLC processing speeds designed to speed-up everything from programming and program verification through to job set-up and actual machining. The Fanuc control option also includes a collision prevention system (CPS), which actively monitors axis feeds, spindle dynamics and the workpiece, in real-time, to avoid collisions, damage and downtime.
The machines also feature a ‘re-located’ front-positioned tool magazine window that helps improve tool set-up operations, and a reduced distance between the operator and work table simplifies job setups. Other improvements include six flood coolant nozzles (on the spindle’s front) to control heat build-up and chip removal, and a flushing nozzle on the machines’ beds to minimise chip accumulation.
As is standard with new DN Solutions’ machines, DVF 5000 second-generation machines feature a grease lubrication system that reduces oil consumption and ensures more eco-friendly machining centres.
Mills CNC says that DVF 5000 second-generation simultaneous five-axis machining centres are ideal for component manufacturers looking to increase and improve their five-axis machining capabilities, and that the range is destined to become the natural choice for manufacturers looking to invest in a high-productivity, high-precision five-axis machine for the first time.
