The invention belongs to the technical field of motor shell production and manufacturing, and particularly relates to a machining process of a new energy aluminum alloy shell. A numerical control vertical lathe with a drilling and milling function is adopted, a special clamping jaw is used, a D-end inner hole, a D-end end face hole, an N-end inner hole, an N-end end face hole and key grooves of the inner holes are machined through two working procedures. In the first step of machining, rough machining is conducted for the second step of machining, the end face holes are drilled and tapped firstly, then the spindle key grooves are machined, and finally the inner holes are subjected to finish machining, so that the working procedures of a traditional production process are reduced, the laborintensity of workers is relieved, the production efficiency of products is improved, and the quality and stability of the products are improved. 本发明属于电机壳生产制造技术领域，具体涉及一种新能源铝合金机壳的加工工艺，采用带有钻铣功能的数控立车，用专用的卡爪，两个工序把机壳的D端内孔与端面孔、N端的内
