RK International signs agreement with aerospace specialist

Added to MTDCNC by RK Int Machine Tools on 03 September 2015

RK International Machine Tools has entered into a five-year agreement with Aeromachinery Ltd to market the range of Modig machine tools. Sweden-based Modig Machine Tools is renowned for being a World leader in innovation and technology in the area of high speed machining. It is best known for its one-hit machining of aluminium aircraft stringers and its research into higher productivity and uptime performance in the aerospace industry is relentless.

Its latest developments include the Modig Extrusion machining centre, designated the HHV it provides a massive 50% productivity gain over earlier Modig Profileline machines, making it the most competitive processing machine in today’s market for machining Stringers or Longerons. The company has delivered more than 40 HHV’s over a four year period, many to customers placing multiple orders. A further development of the HHV machine is its use on bar stock (as opposed to extrusions) this new model features a heavier spindle and headstock. The key advantages of the Modig HHV-BAR machining centre are a reduction in extrusion stockholding; the ability to machine similar designed components from bar; and an entry into precision engineering sectors, such as electronics and medical components, while retaining the ability to machine in one cycle aerospace stringers.

RK International Machine Tools focus will be to develop the market for the HHV-BAR machine within its existing customer base, that encompasses businesses throughout the full spectrum of the UK precision engineering sector, as well as OEM and Tier one aerospace manufacturing, and to identify new opportunities for this high-performance machining system. Key features of the HHV Bar Mill are its ability to machine bar stock up to 140mm square and 5000mm long, four axes (X, Y, Z & U), with 10m/s2 acceleration in all axes and accuracy of +/- 20 arc seconds on the rotary axis, the main spindle is a Fischer version B 30,000 revs/min HSK E63 unit, which is combined with a 24 position tool changer as standard. This combination of features results in cycle times between 40 and 60 per cent faster and the use of bar stock rather than billet reduces material use by as much as 30 per cent and significantly reduces fixturing requirements.

'At RK International Machine Tools we already supply some of the UK’s leading aerospace companies with machines, both as off-the-shelf and turnkey solutions. With the UK having Europe’s largest aerospace customer base, generating £27.8 billion for the economy in 2013, the Modig range and notably the HHV series machines provide a great opportunity to further advance increases in machine productivity, through reduced component machining and handling times,' says Dick Aldrich, Sales Director, RK International Machine Tools.    

The Modig HHV series is just part of a wide range of machining systems available from the Sweden-based machine tool builder, which specialises in providing solutions for the aerospace sector. The machines range from the Aeromill, with a capability of achieving metal removal rates of up to 850 cubic inches per minute to the Fleximill an innovative six-axis machining centre for aluminum and composite components.
