Description:

In recent years, the mass consumption of resources and climate change have become global social issues. Remanufacturing, which is categorized, is attracting attention in various industries because it has high economic efficiency due to the resource saving effect by reusing inner parts, low manufacturing cost, and new employment creation.
The remanufacturing industry of construction and mining equipment has a relatively large market size as regular maintenance and parts are larger and more expensive than other industries components. Among various remanufactured components, carburized gears and bearings, which are often used in prime movers and reduction gears, are one of the parts that are prone to wear and surface damage under high load conditions.
In this theme, we will introduce the development contents of non-destructive testing and functional recovery technology. that specializes in remanufacturing for this issue.
