4. Machine Description
4.1. ARG 220 D(F)-NC Automat
(inside)
The simplest design of NC automatic
machines manufactured. It is especially
intended for cutting sections and full
materials of small diameters. The
maximum length of a single feed is 500
mm. The required workpiece length is
easily set with a hand lever and displayed
on the digital meter. Two cutting speeds
40 and 80 m/min. The F-NC model is
equipped with a more powerful motor and
a frequency changer allowing for setting
optimum saw blade speed between 15
and 90 m/min.The optimum setting of saw
blade speed towards the workpiece
increases the productivity of the machine
and the saw blade life.
