Ultrasonic measuring systems ZUMBACH’s UMAC ® RZ65 ultrasonic eccentricity and wall thickness scanners for cable insulations, tubes and hoses allow maintenance costs to be reduced. Thanks to a new design, the transducers can be synchronously adjusted within seconds to the best possible measuring position. The scanners cover an outside diameter range up to 65mm (2.5"). They represent a smart and simple solution for fully non-contact, in- line eccentricity and wall thickness measurement. Some of the benefits include: quick centring thanks to the eccentricity measurement and adjustment, regard- less of the materials’ temperature; completely automated process

it is 100 per cent made of non-corrosive materials for maintenance-free long-life operation under water. All ultrasonic UMAC ® systems offer flexible mounting options including inside cooling troughs and spray tanks or in a separate installation tank provided by Zumbach. Using additional components, such as proven WALLMASTER data acquisition, processing and display systems, ODAC ® or MSD diameter and ovality gauges, KW lump and neckdown fault detectors, a UMAC ® WALLMASTER system can be extended for any purpose. These systems provide flawless SQC/SPC reports of the final product.

Innovative developments in orbital cutting

sharpening and to the different type of teeth in addition to a new coating that is specially studied to increase the life of the tool and to reduce friction between blade and tube. The company’s technicians have been working with customers during the phase of design of the blade and during the tests, providing technical assistance and advice. After the initial purchase the cooperation continues between the customer and Moreschi. Thanks to this teamwork the Moreschi blades reach performances of cut of 16m 2 . Very good results have been obtained not only with new blades but even after the resharpening. For many years Moreschi has offered an accurate after sales service of maintenance and resharpening of the blades, not only in Italy, but for customers from other European countries.

the development of the tool. In fact the blade that is used for this type of cut is subjected to a system of forces that are different from the traditional cut. To solve these problems Moreschi has developed a high performance and specific product in collaboration with the main manufacturers of cutting machines and with the biggest tube manufacturers. It has designed a new tool designed to cope with the different geometries of

RECENTLY the welded tube market has increasingly favoured the use of orbital cutting because this technology offers several benefits, according to Moreschi, Italy. The first benefit of orbital cutting is the possibility of increasing the velocity of the line with consequent enhancement of production thanks to the usage of two or four tools instead of one. The second benefit is the longer life of the blades due to the reduced dimensions of the tool and to the greater rigidity. The third point concerns the better finishing that is obtained even through the reduction of the vibrations (in this case the choice between several variables during the phase of design can make the difference). The fourth benefit is the reduction of waste produced. In spite of the advantages above there are also some difficulties during the phase of cut such as the high velocity of revolution of the blades and the mechanical stress. The system of orbital cutting that is innovative, even for the manufacturers of machines, should be studied in close collaboration and at the same time with
