was conceived, designed and developed in order to help extruders eliminate and recover the aluminium butt. Recovering aluminium rather than dissolving it in the soda is a quantifiable financial benefit.
The machine allows to eliminate the aluminium residue, that is also called butt, anytime a die-holder with incorporated feeder plate is used. In the traditional process the entire stack, die-holder and die or simply die and aluminium butt, is immersed in the soda bath, a very expensive process, particularly health aggressive and implying also the burden of waste disposal. The machine on the contrary allows cutting the butt in a simple and easy way and avoids the waste of some kilos of recyclable aluminium. The actual cost saving and the amortization in a few months deserves the attention of every extruder.
The machine is equipped with a movable table with hydraulic feed enabling carrying out automatic rectilinear cuts of the butt.
The workbench is mounted on round cylindrical guides with recirculating ball bushes, eliminating sliding friction also under heavy load.
ARM ALUMINIUM RECOVERY MACHINE® is provided with a graduated scale, displaying the selected cutting length with stop at the cutting end.
The machine is manufactured with a welded and tempered steel structure duly designed to resist to cutting strength.
The hydraulic clamp, which allows die locking during the cutting stage, is driven by a double acting hydraulic cylinder with a stroke of 200 mm and has a tightening working capacity up to Ø 520 mm.
The "V" shaped plate allows optimal positioning and centring of the die.
The lubrication with vegetable oil by means of a pneumatic micro vaporizer allows you to adjust the pulsations per minute and the amount of liquid to spray.

For best results it is recommended that the first 6 cuts are done at ½ the feed rate (30mm/min or 1.2”/min). If this procedure is not followed the blade life will significantly decrease. This is the standard procedure for all band saws not just the ARM.
For an ideal lubrication of the saw blade we recommend the use of the lubricant BARALDI-MOTUL Tech STAG 40/2 BC. Vegetable compound, specially studied for the cutting of the aluminium butt with ARM and for cutting both hot and cold billets by means of circular saws.
The machine is supplied in compliance with CE standards or alternative ones.
