Wire cleaning for plating quality The new in-line Pressure Wet Cleaning (PWC) system is developed to clean drawn wire from lubricant residue to obtain a smooth and glossy finish in ‘plating’ quality, at 6-14m/s (1,200- 2,800ft/min), dependent on wire size. The system simultaneously performs surface cleaning and polishing, in-line with wire drawing machines and is used for the most demanding wire cleaning and polishing applications using standard cleaning medium, including cold water, water emulsions, oil, etc. The wire leaves the cleaning unit completely dry, ultra-clean, and with a highly reflective appearance. particularly recommended for cleaning applications in which a traditional process is inappropriate, especially with wire The PWC system is Faster and more accurate SLP probes Laser Design, Inc, USA, a manufacturer of 3D laser scanning systems, has announced that its next-generation line of 3D laser scanning probes will be available from the second quarter of 2007. The company’s new and improved Surveyor Laser Probes (SLP) are faster and more accurate than their predecessors. Included in the new line are the high precision SLP-250, and the SLP-2000 which features a laser line more than twice as long as competing probes. Both of the new SLP models deliver virtually noise-free scan data as a result of breakthrough, proprietary advances in the electronics and optics architecture. The SLP-250, with a laser line length of 25mm, scans at ultra high speeds with an accuracy of up to ±6µ and is primarily used for small or highly detailed objects. The lightweight SLP-2000, with a laser line length of 200mm and accuracy of ±80µ, is an efficient 3D laser scanning solution for large parts. The company indicated that the new SLP models would be available with their fully integrated DS-Series line of CMM-based scanning systems. In response to the needs of the automotive, aerospace, automobile and other industries, the new SLP probes were also designed to be fully integrated with

the portable 7-axis arms from Faro, as well as with the Renishaw PH10 indexing system used on most traditional CMMs. “These SLP probes can be used interchangeably with portable CMMs, traditional CMMs and Laser Design’s own Surveyor DS-Series, DT-Series and TS-Series 3D Laser Scanning Systems that provide highly automated, programmable scanning of parts or objects,” according to company president Martin Schuster. All of the new probes gather data with higher densities than before, upping the resolution by 50% to 750 points along the laser line. “The data from the new models is less noisy, especially on reflective surfaces,” said Mr Schuster. “With less noise, the results are more accurate and less data editing is required.” Each of the probes has dual CMOS receptors that capture up to 75,000 points per second, making them suitable for high-speed, non-contact 3D scanning. The dual receptors inside the probe reduce the number of scanning passes because they capture more part geometry per pass than low-tech single receptor laser probes. SLP laser probes interface to PCs using a standard USB connection, are easy to install and can scan anything from small, detailed parts to large automotive and aerospace parts. The probes are also integrated with Laser Design’s Surveyor Scan Control software

coating, zinc coating, copper coating, painting, etc, and wire cleaning prior to heat treatment applications including patenting, annealing, welding (mesh, chain), cladding, etc. In demanding applications, including the production of highly reflective wire, the PWC system revolutionises the wire cleaning, enabling considerably higher surface quality of the end product, benefitting from the new Decalub wire intermediate dry re-coating process, allowing a smooth and ‘frictionless’ drawing with completely water soluble sodium lubricants in all drafts, easy to clean in-line at high speed with rust preventive additives. As a consequence, the PWC offers significant downstream benefits and savings with the potential to displace for ease of use and compatibility with numerous positioning systems. Additional SLP models using the new electronics and optics architecture are under development and will be introduced later this year.
