Voltage transformer - place it between the electric supply of the premises and the electric supply of the
machine. It allows to work with a different voltage than the standard one (that is 400V / 50 Hz). Available
voltages: 230V, 460V, 500V, 575V.
BAND CHOICE
In this paragraph we recommend the type of cutting band in accordance with the material to use . To get the
best performance from this machine it is necessary to undestand the right use of the used tools and what
you have not to do with them.
The band you have to use must have the following sizes ( in mm. ) :
maximum lenght = 2770
minimum lenght = 2750
total height = 27
thickness = 0,90
Blades with a different thickness can be utilized by changing appropriately the width of the blade guides (see
the paragraph ADJUSTMENTS ) and the band tension.
The blade material is also important; generally the bi-metal blade is used, with different levels of HARDNESS,
named M42 or SVGLB (for general purpose: tube, solids and profiles, available in all pitches), M51 or
SHL (preferred for big solids of hardened steel, INOX material too, available in 3/4 and 2/3 pitch).
The teeth hardness increases - and the fragility too - by going from the material M2 to the M51.
To make a good cut it’s crucial to choose the right pitch (t) or NUMBER OF TEETH PER INCH (z). The
blade must generally have the toothing as follows:
- small teeth when cutting thin materials, tubular and profiles.
- big teeth when cutting solids or pieces with a long cutting section (for example the central part of a U
profile), or in case of softer materials such as aluminium, copper, soft bronze.
By choosing the suited pitch you can avoid a lot of mistakes and you can get a good blade penetration and
the necessary room for the chips. If you cut more pieces at the same time, you must consider them as a
single piece (that is, you have to consider the total size). The enclosed chart gives the necessary
information for a correct choice. It can however be updated or modified by the user according to his
personal experiences.
Even if there are blades with constant pitch, most bandsaws allow the use of blades with variable pitch, that
is, groups of teeth having different pitch one from each other, which reduce vibrations and noise and improve
the quality of the cut and the cutting performance.
