Mills CNC, the exclusive distributor of Doosan machine tools in the UK and Ireland, last month attended the Southern Manufacturing exhibition for the first time in the company’s history. To mark the occasion, Mills CNC showcased the latest Doosan simultaneous five-axis machining centre on its stand.

The machine, a DVF 5000, made its UK debut at MACH 2018, where it proved to be popular with show visitors. Under power at Southern Manufacturing, the DVF 5000 demonstrated the five-axis machining of a complex, high-precision aerospace component.
The Doosan DVF 5000 is a compact, rigidly built machine that provides precision component manufacturers with full simultaneous five-axis machining capability. At Southern Manufacturing, the machine was exhibited with a 17.5 kW/12,000 rpm directly-coupled spindle, although a 22 kW/18,000 rpm built-in spindle option is also available.
While the DVF 5000 machine on Mills’ stand was equipped with a Heidenhain iTNC640 control, models can also be specified with either the latest Fanuc or Siemens CNC. The DVF 5000 offers rapid rates of 40 m/min in its X, Y and Z axes. At the show, the machine was equipped with integrated automation provided by a six-position automatic pallet changer and a servo-driven ATC that can hold up to 120 tools and offers a 1.3 second tool-to-tool change-over time.
The DVF 5000 features linear guides and an integrated thermal compensation system that mitigates against the effects of thermal drift. A 500 x 450 mm table with a maximum table load of 400 kg featured at Southern Manufacturing, but the machine can be supplied with a larger table as an option (630 x 450 mm) if required.

As part of Accuturn’s growth strategy, the company is expanding its capabilities with the addition of a further Haas Mini Mill to its range of CNC milling and turning machines. Director Nicola Stokes says: “This will enable us to increase capacity for our existing customer base, as well as allow us to expand into new sectors.”

The new Haas Super Mini Mill has a machine table capacity of 914 x 305 mm, and axis travels of 406 x 305 x 254 mm in X, Y and Z. Accuturn’s Super Mini Mill is enhanced with a faster tool changer, faster spindle and higher rapids for improved production and part finish.
In other news at Accuturn, which is based in Norfolk, the company has taken its first apprentice as part of the company’s continued growth and commitment to encouraging young people into careers in engineering and manufacturing.
Joshua Mallett, 16, from Swannington in Norfolk, originally came on work experience from Reepham High School for two weeks. He stayed in touch with the business and, after finishing school, joined as Accuturn’s first engineering apprentice. Mallett is attending City College Norwich for the next two years, on day release, studying for his Mechanical Engineering Level 2. On completion, it is planned he will go on to a third year to complete Level 3.

Top tier suppliers to the oil and gas sector need to work smarter, quicker and more cost-effectively to not only meet customer demands, but ensure that their own bottom-line margins are maintained and, ideally, improved.

As part of Starrag’s product ranges, machines from Dörries and Scharmann, in particular, are paying dividends in global oil and gas work. For example, Burckhardt Compression in Switzerland is reducing unproductive times on piston compressors produced using its portfolio of Dörries and Scharmann machines, which are complemented by high levels of automation. In the Netherlands, Mokveld is reducing formerly long machining times, as well as possible relocation errors and certainly costs, by machining its high-pressure control and stop valves complete in a single set-up on a Dörries vertical lathe. Elsewhere in Europe, one-hit machining is benefiting KSB of Germany, with a Dörries vertical lathe minimising unproductive times and replacing two/three conventional machines in the production of pump housings.
In every case, Starrag can easily and cost-effectively ‘modify’ and supply each machine specifically to suit individual requirements.
Manufacturing piston compressors that operate up to 3,600 bar, Burckhardt Compression uses a quartet of Starrag machines – a Scharmann Alpha 1250 M machining centre, a Scharmann Heavyspeed two-ram-type boring mill, a Dörries Contumat VC 2400/200 vertical turning lathe (VTL) and a Scharmann Ecoforce 2 HT4 machining centre – to machine cylinders, cylinder blocks, frames, valve heads and steering rods. Components are produced up to 5.9 m long and weighing 30 tonnes.
According to August Dünki, the company’s director of large part manufacturing: “We especially gain benefits from the use of the Dörries VTL’s additional moveable work table axis [for set-up and/or in-situ workpiece inspection] and have reduced unproductive time via the 72.4 hp Ecoforce 2 HT 4.”
