MZR 1.3/1.5 cylinder block machining line

摘要

Engine parts machining process requires environmentally-friendly technologies, with energy saving and no wastes, as well as high-precision machining. In constructing a new cylinder block machining line for MZR 1.3/1.5 engine mounted on New Demio, Mazda has developed and adopted a number of new technologies and systems of our own to improve machining accuracy and achieve an environmentally-friendly process. This paper introduces ①A new process for enabling much higher accuracy in cylinder bore finishing, ②Ecological coolant-less machining, that results in reducing significant machining energy and wastes.
