Large field scanners for diameter control in cold processes

ZUMBACH Electronic, Switzerland, has extended its range of ODAC ® laser scanners for non-contact inline diameter measurement for large size solutions. With the ODAC 550 it is now possible to measure large steel

bars, tubes and rolls up to 500mm or more at accuracies of a few metric microns and rates of up to 2,000 measurements/s. Other materials, such as titanium, brass, alloys and plastic, work as well.

This was made possible by the development of a revolutionary optical scanning technique with a highly parallel and seamless measuring field (no dead zone). The technology also allows mounting emitter and receiver far apart from each other, depending on the available space conditions. Typical processes where the system offers new solutions are peeling, grinding, polishing and straightening, as well as in quality control lines (NDT). The dimensional data for diameter, ovality, etc, can be fed directly to the user’s network or displayed in real-time for the operator by USYS processors, and also for feedback to the machine. Complete accessories like secondary protection enclosures, cooling devices, air purging and air knives are available for heavy-duty environments.

Automatic tube finishing machine ML100 3Z

ML100 3Z is a round pipe polishing machine with three independent abrasive stations. It finishes tubes from Ø10 up to 114mm in one single pass using a combination of different abrasive grains. This machine is ideal for stainless steel tube finishing where high quality is demanded. In ML100 3Z not only round tubes can be polished, but also oval shapes. Due to ML planetary system the abrasive belts rotate around the tube giving flexible finishing without spinning the tube. This enables the safe work of long tubes and also of drilled tubes. In order improve the tube supply autonomy of the machine NS has developed a new in-feed and out-feed system that makes continuous transport of tubes possible, avoiding labour costs and reducing non- productive periods of the machine. This

tube finishing machine has an optimised program of tubes feeding, minimising the gaps between them and improving its global productivity. This new system is able to feed and polish tubes with different lengths in the same sequence, working from a minimum tube length of 450mm. As the feeding is done from the front of the tube unlimited lengths can be worked with this tube finishing machine. The standard capacity is designed for 10 tubes, but a higher number can be done with different versions of this loading and unloading tube system. ML100 3Z brings a new energy-saving feature. This tube polishing machine is now equipped with a tube detection program, which automatically stops the abrasive belts motors every time there is no tube on the

finishing stations. This automatic motor start and stop system reduces not only the consumption of energy, but also of bearings, rollers, V-belts and other mechanical components. This automatic tube feeding system is also compatible with double and single station tube finishing machines in dry or wet versions. Ideal for different types of tube finishing businesses such as balustrades tube finishing, tubular stainless steel furniture finishing or finished stainless steel tubes wholesaling, ML100 3Z automatic conveyor system is applicable to every tube finishing activity where time, quality and machine autonomy are essential.
