During the machining of the crankshaft of the engine, the discharged iron filings contain waste grinding oil. In the past, these oil-containing iron filings were sent directly to the iron filings yard for uniform treatment. In the process of waste grinding oil discharge, the splashed oil contaminates the equipment. After half a month's efforts, the QCD Improvement Department of the factory made a waste grinding oil treatment device on the basis of the use of old materials.
Dongfeng Commercial Vehicle Engine Factory's waste grinding oil improvement was praised by German experts
Recently, a waste grinding oil processing unit was put into use at the dCi11 crankshaft grinding machine cooling station of Dongfeng Commercial Vehicle Engine Factory. The problem of waste grinding oil treatment that has plagued the factory for many years has been completely solved. According to the current two-shift system, two such equipments can save 375,000 yuan in one year. German engineers who provided services to the plant fully affirmed this improvement.
