www.chinabuses.org: Recently, Sino Truck organized development of three kinds of MAN engine parts (including oil cooler cover, front cover and intake valve), which have been into batch production. Chassis parts department keeps enhancing development of MAN products and extends classifications of new products. It endeavors to improve product structure of the department and equipment utilization rate, and increase sales revenue.

Since developing aluminum parts of three kinds of MAN engines, processing department pays much attention and prepares processes of early planning, choice of machine tools, technology, manufacturing and design, tool-making, gauge preparation and NC machine tool preparation. In the beginning of October, trial-manufacturing and processing of these three kinds of aluminum parts work blanks began.

In the process of trial manufacturing, technological department makes improvements against lack of work blank remained and deformation of work blanks. The detailed improvements are increasing work blanks left and decreasing deformation; timely contacting the manufacturer to adjust tools to adjustable position when locating facing milling is insufficient for satisfying positioning requirements; duplicating two sets of tools and inner-cooling alloy drill bit for decreasing cutting time. Meanwhile, enhancement of tool rigidity ensures precision of position of processing hole as well as improves product quality.
