Cutting parameters:

A CC type cutting machine, having the
correct cutting parameters and the proper
saw blade, guarantees a quality cut.
There are two cutting parameters.
The rotation speed of the cutting tool
-
(RPM), expressed as revolutions per
minute.
- The speed with which the tool advances
(A), expressed in meters per minute.
RPM can be regulated with the variable speed
control on the electric cutting. Consult the table
on page 3.
Rotation Speed RPM:
The rotation speed RPM is found using the
formula:
RPM = (1000 x Vc) / (3.14 x D)
Vc = the tool's cutting speed in m/min
D = the tool's diameter in mm
Hardness of the material

Advancement speed A:
The advancement speed is found with the
formula:
A = Az x Z x RPM
A = advancement speed in mm/min
Az = advancement speed by tool teeth in mm
Z = number of tool teeth
RPM = Cutting tool rotation speed in rot/min

The tube's fastening:

Warning: It is extremely important, so that the
machine will not be damaged, to support the
tube both in front and behind when it extends
beyond the machine for more than 300 mm or
if there is an overhang weighing more than 5
kg.
Good alignment between the fastening of the
tube and the machine guarantees the cut's
perpendicularity.
The alignment between the cutting machine
and the fastening system for the cut tube
avoids pinching the
guarantees its longevity.
