Accurate length
saves costs
Sikora’s Length 6000 is a system for
non-contact online length measurement
of cables. For this method, the product
image and its movement are defined and
thus the speed and the produced length
can be calculated.
The technology of the Length 6000 is
based on an optical measuring principle.
In combination with two laser diodes, two
image sensors are positioned next to each
other. In sequence the cable passes both
image sensors.
The time the product takes to move between the first and second sensor is
measured. Even with reflective surfaces the high-resolution image sensors
determine the structure using patented diffraction analysis.
Mechanical systems provide only limited precision, due to the slip on the product
surface, and the Doppler method is not suitable for reflective, or smooth surfaces,
for example, and requires an accurate product guiding.
The technology of the Length 6000, which defines the length through comparison
of image patterns, is reliable for round products and for products with reflective
and smooth surfaces. The system calculates the length independent of the product
direction and measurements start from zero line speed. Length measuring devices
ensure that the required cable length is produced and delivered, as short- or over-
lengths always lead to profit cuts.

Regular die checks safeguard
product quality
Die Quip specialises in machines to produce dies in-house, to reduce production
time and improve quality. It is important to ensure that dies are within tolerance
before production begins and, if there are drawing problems, to be able to assess
whether the die or the process is at fault. The ability to measure die diameter,
angle, bearing length and surface finish will reduce die changes and ensure
product quality.
Wire mills without an internal die shop should have an inspection programme for
incoming dies to prevent out of tolerance dies getting into the production process.
Die Quip provides simple tools used in die production, such as calibration pins to
check the diameter, eye loupes for surface inspection, angle plug gauges to check
the reduction angle or Die Quip’s own Die Check to measure bearing lengths.
Final inspection of supplier or in-house dies can be done with optical and tracing
systems for dies of 0.5mm and larger. To inspect surface quality, Die Quip has an
extensive line of microscopes with a range of magnifications, lighting options, die
stands and cameras to capture the image.
Die Quip also offers calibration gauges treated with black oxide to show exactly
when gauges are wearing out of tolerance. No more guess work or tedious
measuring of gauges to determine if still in specification - simply use the gauge
until the treatment wears off and then replace it. These gauges have a 10 micro-
inch surface finish and are hardened to 60–62 Rockwell C. They are available
individually, or in sets from 0.22mm–12mm.
