Recently, China National Heavy Duty Truck Group has developed three types of engine parts (oil cooler cover, front cover, intake pipe), and the product has entered the mass production stage. The bottom-end processing department of the parts manufacturing department continuously increased the development of Man's products and expanded new product categories, and strived to improve the product structure level of the processing department, increase the equipment utilization rate, and increase sales revenue. Since the implementation of three kinds of aluminum engine aluminum development work, the processing department has attached great importance to seriously organize and participate in the pre-planning, machine tool selection, process preparation, tooling design and manufacturing, tool manufacturing, gauge preparation, CNC machine tool program preparation process. In early October, trial trials were started on three types of aluminum billets. During the trial production process, the technical department made further improvements to the shortage of blanks and the deformation of the blanks. The first was to increase the blank allowance and reduce the occurrence of deformation; the second was to find that the positioning surface was not fully milled when the intake pipe was processed, and timely contacted the manufacturer to adjust the tooling. , The fixed positioning was changed to adjustable positioning, and the adjustment fully satisfied the processing positioning requirements. Third, two sets of tooling were duplicated and internal cold alloy drills were customized to reduce the cutting time. At the same time, the increase in the rigidity of the tool ensured the precision of the position of the machining hole and improved the product quality.
