offer high product and process quality as well as sustained cost-
effectiveness through continuous investment in its workshops.
The company supplies its products to mechanical engineering, steel
construction, the construction/plumbing trade, the boiler and plant
construction industry and the ball bearing industry. It offers threaded
black and galvanised tubes, water boiler tubes, linepipes up to 4" OD,
boiler tubes, quality grade I/III and ball bearing tubes and can deal with
steel grades: St. 35.8, TTSt. 35, St. 37, St. 52; 15Mo3, 13CrMo44,
10CrMo910; 100Cr6; as well as other steel grades on request. Its

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.
