Our factory designed an eccentric fixture for machining the crankshaft surface, as shown in Figure 1. In the past, it has been processed by the trampoline, and the positional accuracy of the φ30mm hole and the two center holes is difficult to ensure, especially the coaxiality φ0.02mm can not meet the requirements. High surface roughness, low productivity, and easy to scrap. Later, we switched to lathe processing and specially designed a set of fixtures as shown in Figure 2.
