Diameter gauge heads
in comparison
SIKORA’S Laser Series 6000 measuring
devices deliver precise diameter
measurement with reliable lump
detection. The devices perform at a high
measuring rate of 2,500 measurements
per second, each with a high single
value precision by default. With a
dedicated accuracy of 0.2µm and a
repeat accuracy of 0.1µm, the diameter
of tubes and hoses is continuously
measured online.
A wide size range of gauge heads
covers a diameter range from 50µm
to 500mm. Three gauge head models
of Laser 6000 Series are available for
product diameters from 0.2 to 78mm,
and combine a large number of features
which help to simplify daily production
routines.
Sikora’s R&D manager, Siegmar
Lampe, commented, “Our development
priority is to maximise the benefits to
our users. Thus, we have developed
many features for Laser Series 6000
that significantly support the user on
the line.”
The high measuring rate of
the diameter measuring devices
progressively and effectively enables
the detection of lumps and neck-downs
on the product surface. This reduces the
cost of investment and increases space
on the line, since only one gauge head
need be installed.
The LCD display and operator panel
are directly integrated into the gauge
head providing easier operation and
process control. The operator can see
the diameter results on the display at
a glance. Simultaneously, the panel
shows the diameter rated value and the
control module can be activated. The
control module automatically adjusts the
diameter to nominal value via control of
the line speed or extruder rpm.
The physical aperture of the gauge
head is twice as large as the product
range, permitting easy and safe feed-
through of the product. A special feature
is the pivoting head design. The gauge
head can be temporarily swung out
of the production line path if required.
The bottom of the unit is open, so
water and dirt fall through, rather than
contaminating the measuring field. The
feeding of the connection cables is
protected, directly in the gauge head
stand.
The Laser Series 6000 offers an
optional Wi-Fi interface, which allows
direct connection to a smartphone or
laptop.
This interface enables diagnostics
and quality control with video signal
in addition to transmitting measuring
results, trends and statistic data. Sikora
provides its own app for displaying
measuring results, trends, statistics or
video signals directly on compatible
smartphones. Simply log in via the Wi-
Fi interface and immediately you have
measuring results on your smartphone.
The app also offers the possibility to
calibrate the gauge head according to
ISO 9000.

New rotary draw bender
IN confirmation of its on-going
commitment to meet the market’s
growing needs, Ercolina has launched a
new and improved rotary draw bender:
the TB130 Top Bender.
The TB 130, with its 130mm (5")
capacity is suitable for producing
consistent quality bends in large pipe,
tube, squares, solids and other profiles.
A strong cast iron design matched
with high precision planetary reducer
ensures quality, repeatable bends.
An interactive PLC touch screen
control offers easy access to auto and
manual operating modes, programming,
system diagnostics and multiple
language capability. Programmable
bend angles range from 0° to 180°, with
up to 12 bends per program.
Other features include independent
springback compensation for each
bend; USB port for software updates
and unlimited program storage; digital
display of counter bend die axis and
bend angle; bends to CLR as small
as 2D; patented quick-change tooling
system with multiple radii available; and
no hydraulic components, reducing cost
and improving bend accuracy.
Auto load sensing improves bend
productivity while protecting machine
components.
Electrical components are UL, CSA
and CE approved.
