Doosan holds scraping contest for its staff

In a unique initiative, Doosan Machine Tools, recently held a scraping contest for machine tools among its own and suppliers’ employees at its machine tool plant in Namsan, South Korea. Scraping is essential for assembling machine tools, and is a key skill required of workers involved in the production of machine tools. A machine tool moves vertically and horizontally to cut work pieces, so the way its surface comes into contact with a work piece hugely influences its precision.

In other words, scraping involves making tiny, detailed grooves of just several micrometers (0.001mm) that allow lubricating oil to flow onto the contact surface so as to maintain the flatness of the surface and make the surface slippery. If the grooves are too big, the contact surface will wear out and cause abrasion, whereas if the grooves are excessively small, the contact surface will heat up, thus becoming deformed or worn out. As such, the quality of the grooves greatly influence the precision of machine tools, which in turn influence the precision of automotive parts, aircraft parts, medical devices and IT devices, all of which are manufactured using machine tools.

For machine tool manufacturers, scraping is an essential skill for minimising a machine’s friction and ensuring its precision and rigidity. An official from Doosan Machine Tools said, “A machine tool that can perform nano-sized (one billionth of a meter) work requires skilled manual work to maintain the precision of transfer movement within 10 micrometers, which is somewhat ironic. Only very skilled engineers can ensure the precision of machines tools.”

In the contest, 35 contestants were divided into groups that worked for three hours. Six winners were selected for the grand prize, best prize and excellence prize etc.
