ROTOMAC^® EDDY CURRENT ROTARIES Eddy Current Rotary Mechanism to Detect Seam Type Defects in Tube and Bar MAC Rotaries use the unique qualities of eddy current rotary probe technology to detect long continuous surface flaws which may not be detected by encircling test coils. Operate with MultiMac^® eddy current electronics. Systems with two, four, or six probes, each with its own detector channel. Accurate Distance Compensation ensures a uniform defect signal, even with off center or out of round material. Choose test headplates for surface or air ride configurations, depending on surface conditions, sizes, and test specifications. Dynamic breaking for quick stop of test probe headplate rotation. Rotary probes, unlike encircling test coils, are not affected by throughput speed changes such as occur in parts forming, because the probes spin continually around the test material at a fixed speed. Operates automatically as defects in the bar or wire create flaw signals, activate alarms, paint markers and other devices. Test magnetic and nonmagnetic material from 1/8″ (3mm) to 7.1″ (180mm) diameter. Method of Choice for Seam Type Defects MultiMac^® eddy current electronics provide the controls, processing and analysis for the Rotary. MultiMac^® can also assign channels to an encircling coil test to detect short, intermittent defects, in combination with the rotary test, where needed. ROTOMAC^® 25RM SLOW THROUGHPUT SPEED ROTARY Cost-Effective Eddy Current Rotary for Testing Wire & Rod The Rotomac^®25 RM is the latest in MAC’s line of eddy current rotaries.  Packaged with our Minimac^® II eddy current electronics, it provides cost effective, reliable on-line inspection for longitudinal surface defects in wire, rod and heavy wall tube, 3 to 25mm diameter.  It is designed for use in cold header operations, spring making, strut rod production and similar slow throughput operations. Operates at 1000 RPM. Throughput speeds up to 12 meters per minute. Out-of-round product can be inspected using our highly accurate distance compensation with absolute test probes. Bushings keep product centered during test. New air ride probe arm design, with convenient, easy access probe adjustment. Standard singe phase AC power input. ROTOMAC^® 20mm HIGH SPEED ROTARY High-Speed Eddy Current Inspection of Small Diameter Wire, Rod & Tube for Longitudinal Defects High-speed rotary features include: Operation at speeds up to 18,000 RPM for high production output. Highly sensitive non-contact testing with superior results. New and improved, easy to set up Distance Compensation (a critical factor in testing ovate wire). Simple adjustment tools, with convenient dial-in diameter guide. Two spinning test probes that can be adjusted simultaneously for dimensional changes. Quick twist-on bushing holders. Probes that can be easily centered on the test product’s center of rotation. Simple probe replacement. Meets all applicable safety requirements. The 20mm Rotomac^® HS Rotary delivers high-speed ECT (Eddy Current Testing) for continuous wire operations that include drawing, spring-making, parts forming, and shape and cut. The system is designed to detect longitudinal surface flaws such as seams and laps, in products measuring from 2 to 20mm (0.0787-0.7874”) in diameter Applications Include: Continuous wire operations such as drawing, spring-making, and parts forming lines. Straight and cut operations. Operates in-line with straighteners, or off-line in a separate test station. Ferromagnetic, non-ferromagnetic, and austenitic materials. Tests round and ovate material.

Magnetic Analysis Corp. (MAC) has developed an Ultrasonic Spin-The-Tube inspection system utilizing MAC’s Automated Pitch Control (APC) Technology and Precision Design Conveyor.  Capable of handling a larger range of diameters and material that is not as straight as usually required by other test systems, the APC design and conveyor provide a significant new option for this application. At the center of MAC’s full body tube test system is the unique APC transducer carrier and the precision design ”Spin-The-Tube” conveyor. With the use of a simple dial-in pitch controller, the operator can set a precise angle of helical pitch for the conveyor’s rotation of the tube. The conveyor spins the tube longitudinally past the ultrasonic transducers at the correct pitch, and the APC follower rolls automatically adapt to this angle. This allows the APC carrier, with its simple immersion water tray, to handle ovate and unstraight tube and reliably maintain constant coupling and water path during the test. The result is a highly accurate, reliable ultrasonic inspection system.  This design also ensures minimal wear and permits testing of materials with ovality and straightness problems. A recent system was installed and commissioned at a major US Mid-West producer of Seamless and DOM Tubular Products. The machine was designed for Longitudinal, Transverse, Wall Thickness and Lamination Detection to the 5% and 10% level. This particular application required two Test Heads and 30 transducer elements, however, the specific layout and scan plan can be easily modified depending on the customer’s test specifications. The test heads are lifted into the test position beneath the tube by air cylinders before the first transducer is reached, and drops out of position after the tube end passes the last transducer. This ensures the head is securely positioned after the first follower roll approaches, preventing possible damage during normal operation.  All mechanical components are manufactured from stainless steel to prevent corrosion and premature wear. The system’s design allows the tube producer to test a broad range of tube diameters from 50mm to 355mm (2” – 14”) diameter, without changing bushings or glands. A simple one-knob adjustment control and convenient diameter scale are used for changes in dimension, ensuring the UT sound entry point and incident angles remain constant for any tube size. Material Handling is a critical aspect of any Spin-The Tube inspection system and MAC has manufactured a premium grade conveyor to compliment the APC Test Heads. This conveyor is engineered from an NDT perspective and ensures efficient material handling and containment. The Powered Roller Heads are robustly designed and accurately maintain the inspection helix and rotational speed to assure there are no untested areas within the Scan Plan. MAC’s APC Full Body Tester, with or without the conveyor, can be seamlessly installed into an existing production line, whether it’s a new system or an upgrade of an older unit.  It operates with the familiar interface of the Echomac^® FD electronics which provide the critical software for controlling the transducers and receiving, adjusting, analyzing and reporting test results.
