4. Saw blades
Apart from the gearbox, the most unusual feature of the counter-rotating twin-saw system is
the arrangement of the saw-blades. The special blades used on twin-blade saws have two
different sides. The outer face, i.e. the side that faces away from the companion blade, is
smooth and the teeth jut out from the blade disc. The inner face, by comparison, is patterned
with radial webs and grooves and the flanks of the saw teeth are flush with the blade disc.
These special blades are very expensive and are the product of a highly-skilled production
process.
Never fit non-approved blades. Only the original items can provide the precision, running
characteristics and stability required for counter-rotating twin-blade saws. Never use abrasive
blades or grinding blades, whose speed is too low for friction sawing.
The twin-saw system is not intended for use as a single-blade saw. The geometry of the
special blades makes them unsuitable for single-blade cutting. Fitting non-approved single
blades can seriously damage the adapter system and this will in turn impair the function of
the entire machine.
The saw blades do not cut concrete or concrete-similar materials.
4.1 Blade types
CSM: normal range type for almost all tasks
CSM 235 for CDC 2224/CDC 2530
CSH- Blades: For special tasks light
very hard steel and for those materials,
which are sensible for cutting like lead,
aluminum, bitumina (roof tar layers) and
high performed steel. The Titanium coating
hardens the surface and closes it for glueing
materials. Picture left: CSH 310.
