Technology Update
Tube Tech Machinery, Italy, is the
manufacturer of the advanced FL 600
3D tube cutting machine. The FL 600 3D
provides maximum levels of precision,
quality and productivity. It can work with
diameters from 80-610mm round tube,
400mm x 400mm square tube and 500mm
x 300mm rectangular tube, and a maximum
length of 24,000mm.
The tri-dimensional system allows operation
on any point in a spherical space, with
movement along 5 interpolated axis,
precision ball screws and linear motors.
The FL 600 3D is equipped with a double
tube loading system. One loading device
operates from a bundle, which allows the
automatic loading of tubes with round,
square and rectangular section (with a
loading capacity of 10,000 kg). The second
operates from chain, which enables the
loading of open section profiles.
The machine is composed of V shaped
supports: the chains move at variable
speed, according to the tube diameter and
weight. The chains slide on bearings to
prevent noise and wear. The movement
of the piece along the working axis is
guaranteed by four self-centring mandrels,
activated by synchronized hydraulic
cylinders.
A tempered and rectified
precision helical toothed
rack activates the advance,
operated by brushless motor
and precision reducer with
slack recovery system. The
mandrels are designed to
allow the machining of different
diameters and sections, with no
change of tools. An integrated
floating system allows the
compensation of the piece with
uneven straightness during
machining, enabling precision
machining even on particularly irregular
tubes, preventing dangerous mechanical
stress on the mandrels.
Driven by CNC Siemens 840D (2), the
plant is automatically controlled by 2 CNC
controls: one for the handling area and the
other for the laser working area (sphera),
while a third CNC control manages and
supervises the laser source. The 3 com-
puters are set to interact with one another,
with no need for human operation. They
automatically accomplish profile loading,
dimensional control, 3D laser machining
and discharge of the machined parts.
The machine has a laser resonator power
up to 4000W, a mandrel linear speed of
45m/min, a controlled axis of 30, and axis
acceleration of 13m/sec2.
Tube Tech Machinery will exhibit the FL 600
3D tube cutting machine at Euroblech on
stand 11F06.

Latest PQF® seamless
tube plant
Chinese tube producer, Anhui Tianda Oil
Pipe Co Ltd, has placed an order with
SMS Meer, a company of the SMS group,
Germany, for the supply of a new seamless
tube plant. The plant will employ the PQF®
(Premium Quality Finishing) technology
developed by SMS Meer, and will have an
annual capacity of 500,000t of seamless
tubes. The maximum tube diameter will be
95/8". Commissioning is scheduled for 2009.
SMS Meer will provide Anhui Tianda Oil Pipe
with a comprehensive PQF plant solution,
consisting of the key components of the
rolling mill equipment. This includes the
media systems and complete automation,
as well as the whole engineering, project
management, erection supervision and
commissioning, and hands-on training of
operating personnel.
Advantages of PQF technology include
rolling of thin walls within very close
tolerances, lower material and energy
consumption during production, new
possibilities for higher material grades and
greater flexibility in the rollable dimensions.
The PQF tubes meet all certification
requirements, and in environmental
protection, PQF technology results in
significantly reduced emissions. The
