Gravitation Saw Band cutting machine Pilous ARG 520 DC S.A.F.

Massive double-column semi-automatic machine designed for versatile use in the industrial cutting of materials even in the most
challenging and non-stop applications. A completely new revolutionary concept of the band saw arm casting and a unique
design. The massive grey cast iron arm is entirely unique in the category of dual-column band saws. This, and the massive dualcolumn
arm support moving on linear guides ensure excellent stiffness of the whole system and accurate cut during industrial
cutting of full materials. Industrial band 34 x 1.1 mm is manufactured in many versions and allows for cutting of wide range of
materials, including stainless steel or tool steel.
Optimum clamping of the workpiece when cutting is facilitated by full-stroke double-jaw vice which clamps the material both before and
behind the cut. Pressing a single switch will execute complete cutting cycle - material clamping, band and cooling system start, cutting, band
and cooling stop, arm uplift to the original adjustable position and vice unclamping. When you switch to the manual mode you can control all
functions separately.
Easy intuitive controls through a touchscreen on an ergonomic central control panel. The display also shows required lifting height of the
saw band arm depending on the cross section of the material to be cut. Moreover it allows you to monitor the number of cut workpieces in
the current settings and machine diagnostics (PLC inputs and outputs, history of errors). During cutting the display shows saw band speed,
speed of the arm feeding, main engine load and any potential error messages.
The machine is equipped with a high-performance industrial hydraulic unit which allows setting of the contact pressure of the vice. Maximum
cutting efficiency is maintained also thanks to the possibility of setting optimum saw band speed by a frequency converter in the range
between 15 and 90 m/min., which significantly contributes to cutting accuracy and service life of saw bands. Large base and overall massive
framework guarantee exceptional stability of the machine even when cutting heavy workpieces. By default the machine is equipped with a
solid screw chip conveyor. Its location right below the cut ensures optimum removal of chips. The basic version of the vice assembly is also
equipped with an eccentrically placed roller which allows easy manual lift of the material onto the loading area of the vice and therefore its
smooth movement. The assembly is equipped with a material slide behind the cut. High-quality lighting of the work area by a line of powerful
LEDs with a cover.

• In order to achieve maximum accuracy and productivity the machine is designed only for upright cutting.
• Very robust machine construction composes of massive castings from grey cast iron and ensures vibration absorption.
• Large diameter running wheels and precise three-side hardmetal guiding ensure long service life of the band and cutting accuracy.
• Overdesign of running wheel bearings, tensioning wheel system and all rotary parts ensures long service life of the machine.
• Noiseless and maintenance-free band drive is provided by an industrial electric motor with worm gearbox.
• The machine is connected to a complete cooling system with the possibility of regulating the flow on both guiding heads independently and ontwo additional adjustable outlets. The coolant tank with a high-performance pump are placed in the base of the machine.
• The machine checks correct tension or break of the saw band. If the saw band breaks the machine automatically switches off
