Horizon Brown 1500 AP is the Pedrazzoli
branded development in the field of
automatic cut-off machines designed to
cut set lengths from steel bars or other
materials. The machine – which can be
supplied with a drilling unit – is suitable for
90° or inclined cutting of solid bars, tubes
and sections. On request the company
can also supply the machine with a bundle
feeder and a scrap remover-selector.
The drilling unit can be supplied for
automatic cycle operation on steel, metallic
alloy, aluminium and all other materials
the machine can cut. This work unit can
bore holes on tubular sections and bars
up to a maximum diameter of 142mm
and thickness of 5mm. The wide drilling
diameter range is from a minimum of 3mm
up to 20mm.
Drilling tool movement is horizontally
controlled by a controlled axis with a
200mm total stroke, while vertical cams
keep check on travel stop and start
positions as well as on the two speeds
(slow/fast). The double slow-fast command
capability can be used on tubular sections,
which allows drilling of the first face with a
slow advancing speed, progression onto
the second face with a greater speed and
final drilling under a slow speed.
Tool rotation can be undertaken with 4 or 8
gears with manual gearbox. Alternatively, it
can be supplied with an inverter for a speed
range from 300 to 2,000rpm.
During the work-cycle tool lubrication is
fulfilled by coolant liquid or micro-mist
lubrication (optional). The drilling chip
removal is carried out by means of an
optional cutting table cleaner.
IMS software, developed by Pedrazzoli’s
R&D department, ensures simple and
quick work cycle programming according to
a clear setting of parameters. A set of icons
also allows this software to plan the drilling
cycle by introducing the most important
drilling tool control parameters.
