CNC Machining Stainless Steel Spline

A spline is a mechanical shaft with evenly spaced ridges that transmit torque without slipping. By CNC Machining Stainless Steel Spline parts from 304, 316L or 17-4PH bar stock, we reach Ra 0.8 surface finish and ±0.01 mm profile accuracy, guaranteeing silent, backlash-free power transfer in pumps, gearboxes and drive axles.
