EXERON DIGMA HSC 600 milling center was built in 2010 in Germany by
Exeron GmbH. It is an extremely versatile yet compact machine designed
for the production of precision tools and moulds. A number of
state-of-the-art technical solutions, combined with extensive
equipment, guarantee excellent repeatability of the manufactured parts
over many years of intensive operation.
The EXERON DIGMA HSC 600 is distinguished by its extremely rigid
gantry structure, made of polymer concrete. The entire workspace has
been fully maximised to ensure maximum freedom of operation. It
features all the necessary equipment, i.e. a reliable electro-spindle,
a 30-position tool magazine and a large work table with a length of
900 mm and a width of 550 mm.
The machining process is performed fully automatically in HSM (High
Speed Cutting) technology. This technology allows a significant
reduction in cycle time while increasing productivity and maintaining
high quality. The electro-spindle used, thanks to temperature
compensation, does not deform thermally and maintains a constant
temperature during heavy-duty operation and high speed. The cutting
tools, on the other hand, are continuously cooled to increase their
overall service life.
All linear axes are driven by digital drives attached directly to
backlash-free helical gears. Their movement is performed on precision
rolling guide rails with guards. Excellent positioning precision, in
turn, is ensured by direct opto-electrical measuring systems. All this
is complemented by extensive equipment, that includes, among others,
the advanced HEIDENHAIN CNC control with many useful functions, such
as dynamic block recalculation (look-ahead), graphic program test and
tool management. The DIGMA HSC 600/3 CNC machining center weighs 7000
kg.
