The field that requires eddy current test is precision mechanical parts manufacturing, and it is the most suitable test technology for automated mass production test based on its high detection ability for micro cracks that occur after forging, processing, heat treatment, welding, and polishing.
The advantage of crack test using eddy current equipment is that it enables fast, reliable, and automated quality test of mass-produced precision mechanical parts without contact. It not only replaces magnetic part detection, but also provides a significantly higher level of detection compared to other non-destructive testing techniques.
The performance of eddy current equipment and sensors is critical to achieving fast and reliable automated test. To this end, EddyWorks developed its own software (learning function, etc.) and hardware that can maximize ease of use and test performance and applied it to test equipment.
The principle of test is that when the magnetic field generated by the eddy current sensor (coil) is transmitted to the metal close to it, an induced current is generated, which is called an eddy current.
Depending on the physical properties (chemical components) and the degree of structural change of the metal, the size and shape of the eddy current generated in the metal is detected differently, and the equipment detects it and can perform an automated mass production test.
Eddy current equipment can detect the cracks on the test products and perform automated mass production testing.
There are many different types of test products that can be tested such as shafts (bushings), drums, bearings, gears, bolts and washers.
EddyWorks’ equipment can be designed to mix up channels in one equipment with crack detection channels, structure test channels, tap detection channels and their any combinations. And it can simplify the system and lower investment costs.
Customized sensors are available for the special shape of the test object.
EddyWorks provides a sensor dedicated to the trajectory, allowing the entire trajectory to be inspected with just 1-2 scanning times. By using these dedicated sensors, equipment can be simplified and test C/T (Cycle time) can be dramatically shortened. This sensor is attracting attention from many bearing manufacturers at home and abroad.
