Process analysis of v850l and v1160l

1. The gearbox rear cover, reducer housing, inlet and outlet pipes, shaft core hub, steering arm and other parts on the heavy truck are castings with high hardness and large removal amount. How to process at high speed and high stability requires high rigidity and large torque;

2. the parts of oil pump shell, pump housing, fork, connecting rod and case cover are high strength aluminum alloy parts. The machining resistance of such parts is small and the machining allowance is small. Therefore, the machine tool must have high speed and high feed to obtain higher efficiency;

3. The brake shoe plate, brake shoe, suspension support, Qianjin beam and other support materials are mainly nodular cast iron and cast steel. The processing of these parts is mainly milling, drilling and tapping. The machine tool is required to have high speed and torque, as well as three-axis rapid movement to improve the processing speed;

4. the steering gear shell (the passenger car materials are mostly aluminum alloy) and other materials are mostly ductile iron. The machining is mainly boring, milling, drilling and tapping, and the deep hole boring and milling process is high, and the precision is high. It is required that the spindle run out of the machine tool should be small and the verticality is better;
