On-line dimensional surface flaw detection in high-value products

Traditionally, manufacturers have attempted to use a variety of measurement techniques to detect flaws, but these present problems such as the limited measurement points per sensor, inability to measure the full contour of the product, presence of text and labels that create false positives, and blind spots that prevent the detection of pits and slits in the surface. In some cases, these systems offer limited visualisation capabilities, making it diffi cult to verify what was detected. FlawSense digitises thousands of indi- vidual measurement points around the contour of the product to reveal the smallest surface anomalies. It then produces a 3D point cloud image with informative, actionable flaw data that can be manipulated for further analysis. FlawSense can detect surface defects down to five microns with a claimed ten times-better resolution than camera based systems. LaserLinc also says that FlawSense provides more accurate measurements

LaserLinc’s new FlawSense dimensional surface flaw detection system uses high speed laser line triangulation to perform 360° in-process inspection of wire, cable, pipe and tube products, regardless of product orientation in the measurement field. The manufacturer states that FlawSense precisely detects lumps, gels, pits, slits and other surface defects that cannot be identified by conventional laser micrometers, lump and neckdown detectors, and camera-based systems. Manufacturing personnel can review the defects later in 3D for deeper, immersive analysis. Chad Walker, product manager at LaserLinc, said, “FlawSense is not a laser micrometer; it is not a camera or vision system; and it’s not a lump and neckdown detector, although it can perform the same functions as these technologies. “Instead, FlawSense is a high-per- formance inspection system that uses the most advanced laser triangulation technology, and it is significantly more accurate and capable than conventional inspection systems.”

The system is suited to applications involving the measurement of high specification, high-value products, such as subterranean and undersea fibre optic cables; complex armoured cable; power cable; building wire; high-pressure hose for automobile and aerospace; and other demanding applications.

Cable recycling machine solutions As a recycling manufacturer in the Netherlands, Bronneberg has been providing solutions since 1946. The company designs and delivers recycling machinery for ferrous and non-ferrous metals that matches the specific demand of the waste stream to be recycled. of cable strippers for all diameters and sizes. The smallest cable stripper is the Bronneberg KAB-V, with a cutting capacity from 1 to 50mm diameter cable. This table-top device strips cable using a single rotating knife.

The KAB-X model is claimed to be the only machine on the market equipped with a three-way cable-strip mechanism.

As part of its cable recycling equipment range Bronneberg offers a wide selection

The copper wire stripper can process cables from 1 to 90mm at a speed of 50m/min. The machine is easy to adjust, and the accurate cable-guiding system allows even complicated multi-core and triangle-shape cables to be stripped in one pass. The cable stripper is available with a three-phase or a single phase electric motor. The largest cable stripper in Bronneberg’s range is the heavy-duty KAB-W, suited

to the processing of heavy PVC and armoured ground and grease cable. With a cutting capacity from 30 to 180mm and a single suspension of the wheels, it can strip tough cables. In addition to new cable stripping machines, Bronneberg offers a selection of used equipment, which can be viewed on the company’s website. Bronneberg BV www.bronneberg.nl
