Scharmann ECOFORCE in the highest configuration level
Burckhardt Compression AG, based in Winterthur (Switzerland), is one of the world‘s largest manufacturers of piston compressors. It already has an Alpha 1250 M, a Heavyspeed 2 ram type boring mill and a Dörries CONTUMAT VC 2400 MC-V vertical turning lathe,
which are used to manufacture cylinders, cylinder blocks, frames, valve heads and steering rods for compressors from castings and forgings with a high degree of automation. Absolute precision in the micrometre range (20 μm) is needed here, because all of the parts must fit each other exactly during later assembly.
The new Scharmann ECOFORCE 2 HT4, which serves as a replacement for an old Wotan machine tool, closes the machining gap between the Alpha and the Heavyspeed. Number four is again a stand-alone machine individualised according to customer request with a very powerful 54-kW spindle (torque: 3,000 Nm in S1 continuous operation) for medium-sized parts of up to 24 tonnes (X: 3,500 mm, Y: 2,500 mm, Z: 3,500 mm, W: 800 mm).
The combination of head attachments and flexible tool magazine with automatic changes enables the use of large two-blade tools. An RTM 220 Kuka robot tool magazine (for 196 tools) and an automatic pickup magazine for head attachments reduce downtimes. In addition, a facing head (diameter: 500 mm), attachment spindle (length: 1,000 mm, diameter: 180 mm) and
a spindle-driven angled milling head are used. An adapter plate enables the use of existing machining heads on both the Heavyspeed and the Scharmann ECOFORCE.
