Fully Hydraulic High Performance Band Sawing Machine
in heavy duty design for mass production cuts of easy to difficult materials, in solids,
tubes and profiles. The standard precise linear guides (re-circulating ball units with
grease lubricated guide carriage) guarantee maximum life. The standard BasicControl operators
panel ensures optimum machine operation via touchscreen. After making the desired number
of cuts, the machine shuts off automatically. By reducing set-up times to a minimum,
maximum cutting performances are achieved in automatic mode. The precise drive via ball
screw spindle in material feed guarantees an accurate material length
positioning.Frequency controlled bevel gear driving, electronic supervision of the minimum
number of revolutions, saw band breakage-, and clamping pressure control are standard. Of
course, single cuts can be made as well. The KASTO-Universal Hydraulic ensures best
results regarding cutting performance and blade life. The hydraulic side-shifting cylinder
is standard equipment on the KASTOtwin 4 incl. Pos. 1510.
Heavy-duty, distortion -free welded construction
The new KASTOtwin A 4 is equipped with complete guarding. A high degree of safety and
cleanliness is achieved with best accessibility at the material infeed and outfeed side.
Saw unit (saw frame)
Heavy-duty, distortion-free welded construction, modular design, with vibration optimised
Using the latest design, technology and manufacturing methods, an extremely quiet and
vibration-free operation is achieved. This means shorter cutting times and longer blade
Guidance of the saw
Linear guide with two guide carriages on one guide rail. The roller circulation unit
consists of one solid pre-tensioned roller running system. The greased guide carriages
guarantee maximum usable life.
Side guidance via mechanically preloaded carbide guides with quick release for fast band
change. The band back is guided via rollers. Automatic adaptation of saw band guidance to
material cross section.
System for Saw Blade
The saw blade is retracted in automatic
cycle from the cutting surface of the cut-off piece during return stroke of the saw unit
(removal of cutting surface on both sides). The wear at the tooth tips is reduced, longer
blade life can be achieved.
System for Material
After a cut has been finished in
automatic cycle the clamped material to be cut is positioned free of damage for the next
cut; particularly recommended for materials with sensitive surface (standard when ordering
Pos. 1510 - material feed length 59.06 in. - 1500 mm).
Adjustment of the Saw
Fully automatic, according to the materials height, via light scanner.
Saw band tensioning
Hydraulic, electrically monitored, with automatic pressure reduction at standstill of
Automatic stop in case of band breakage.
Cleaning of saw band
Via chip removal brush, motor-driven, synchronised with cutting speed.
Material clamping -
Machine clamping vise
The hydraulic horizontal double clamping vise enables an optimum work piece clamping on
both sides of the saw band, also for cutting of short remnant pieces.
Material clamping -
Hydraulic horizontal clamping vise with standard infinitely variable clamping pressure
reduction. Integrated material-end feeler.
Automatic NC material
Via pendulum bearing feed vise . Safe material transport, even with forged work pieces.
Material feed length 29.53 or 59.06 in. (750 mm or 1500 mm), standard multiple feed, short
cut lengths up to 9.84 in. (250 mm) are achieved by an incremental feed. Material feed via
ball screw spindle. Automatic Zero Positioning of the First Cut-off Piece. After
having entered the requested cut-off length and number of pieces and after having
activated the control function zero positioning, the first cut-off piece is at
once positioned fully automatically at the requested cut-off length and then cut.
