A shaft may look like a simple cylinder, but its performance often depends on the coordinated relationship between diameter, shoulders, threads, keyways, runout, straightness, and surface finish. CNC turning usually produces the main shaft geometry. Milling, drilling, grinding, and finishing operations [&hellip;]"}
