Detection systems for copper and copper alloys

CONTROLE Mesure Systèmes (CMS) designs, develops and manufactures quality and productivity solutions for all industrial applications, for ferrous and non-ferrous metals. Its NDT range of products in eddy current and ultrasonic testing methods include high- performance instruments and systems, probes and transducers, accessories, and complete turnkey machines with associated mechanics. Applications for copper and copper alloys tubes include detection of swimmer position inside the tube during the manufacturing process; eddy current defect detection on double wall tubes; and junction detection on copper alloys on double wall tubes with six eddy current Zet@ Micro instruments, managing 12 lines simultaneously. CMS also provides other NDT systems for tubes in steel, stainless steel, carbon steel, titanium and zirconium. All systems meet quality standards such as API, ASTM and DIN, and can be used on-line and off-line.

High-performance cutting of 300-series stainless steel tubes with a wall thickness of 3-6mm is the primary area of application for this type of saw blade. Based on a constant, conservative cutting speed of 80m/min and constant tooth load of 0.06mm/tooth, the new Kinkelder Connexxioncut 4 (CX 4) saw blade range cuts 60 x 4mm tube in under four seconds. With these parameters, a steady blade life of 3 to 4m 2 is reached. “That’s at least twice as fast and twice the blade life as what’s normally being achieved with HSS saw blades,” said Dave Hiddink, application engineer at Kinkelder BV. “The cutting surface is virtually burr free,

which is similar to what can be achieved with HSS saw blades.” With CNC machines, which allow applying of variable cutting speed and variable feed rate, even shorter cutting times are possible. “We applied cutting speeds of 120m/min and a tooth load of 0.1mm/tooth and achieved well over 2m 2 cutting surface on tube 60 x 4mm (3,000 cuts) without compromising the cutting surface.” Commenting on his own experience, Mr Hiddink said, “While cutting 3,000 tubes 60 x 4mm normally takes two shifts when using a HSS saw blade, the CX 4 saw blade does the job in one shift. This effectively means the cutting tool has easily paid for itself.” Connexxioncut 4 saw blades are available in diameters from 225 to 630mm for both stationary and flying cut-off applications.
