Pentamac introduces moving
column CNC machining centre
PENTAMAC, Italy, has integrated a new larger capacity machine
into its workshop, which allows it to handle tubes with a length of
up to 7,500mm. The new Moving-Column CNC Machining Centre
XL series are also faster and more versatile for drilling, processing,
tapping and milling iron, steel
and aluminium. The spindle
power (ISO40) is 7.5/11Kw
with higher torque and power
compared to the standard for
vertical centre machines.
Rotary tables mean the machine can also work tubes and cylinders with
“continuous” movement through the support of lead guides. They are
equipped with disappearance protection and double cooling circuit air/
liquid that can be mixed to create the required level of lubrication.
The machines are also equipped with Numeric Control VISEL
VSC1020M, which Pentamac says make it easier and more intuitive
to use with the help of interactive graphics and pre-edit fixed cycles
(macros), which can be programmed with numerous working cycles
for boring and milling. Programming can be completed using ISO and
by receiving files directly from CAD-CAM.
