Precise and fast flaw detection capabilities

ZUMBACH’S triple axis Odac Trio laser diameter gauges provide a number of advantages. Three synchronised measurement axes in one single plane provide comprehensive measurement coverage, peak-precision diameter and ovality measurement as well as precise and fast flaw detection capabilities. Such combinations help to reduce system costs due to the combination of diameter measurement and flaw detection into a single measuring device. Optimum process control in continuous manufacturing processes are guaranteed thanks to high precision and reliability. The combination of fast scan rates and precise and reliable measurement contribute to the reduction of scrap and production costs, ensuring the manufacturing process remains profitable. Laser measuring heads from Zumbach are known for precision, quality and ease of use. The technological basis considered for these measuring heads is always of the latest cutting edge technology, with laser diodes as light sources combined with intelligent and powerful measured-value processors, which facilitate a simple and flexible integration. Unavoidable fines (abrasive particles) generation, the most destructive lubricant contaminants in wire drawing, is no longer an alarming phenomenon since the introduction of the Decalub green and dry rod preparation and wire lubrication by PDH coating system. In demanding wire applications, the PDH die wear is reduced to about 0.2 microns per tonne, meaning the three-body abrasive wear is virtually eliminated. Generation of abrasive particles (fines), continuously liberated from the wire surface during drawing, are PDH captured, encapsulated and transported with drawn wire out of the machine. The lubricant film created is of such a configuration as to induce a

Main advantages include: • 9,000 measurements per second • Three synchronised measurement axes on one single plane • Reliable detection of the ovality • Yields highly accurate mean value, regardless of the orientation of the product ovality • Increased measurement accuracy and reliability • High dirt and dust tolerance ❍ A selection of Odac Trio measuring heads

Among the outstanding features are single scan calibration (CSS), single scan monitoring and high data rate output of up to 200 data packages per second. The measuring heads can be used with all line speeds. Vibrations during production have no noticeable influence on measurements.

The PDH high-performance specific coat is hard, having high density, adjustable in thickness, and is largely sufficient to retain all liberated abrasive particles from wire surface. Applications include all plain carbon wires up to 0.98% carbon, coated or uncoated, and stainless steel alloy wires up to 26% chromium. Decalub – France Website : www.decalub.com
