Once an axleshaft leaves the grinding machine, Currie's splining technician readies the shafts for the spline-cutting tool. Our shafts were spec'ed out as 35-spline; however, the same computer-controlled machine can cut any spline count a customer needs, and with a simple calibration change, the tool can be reconfigured to cut virtually any spline count. The spline cutter utilizes a spinning tool bit with a series of special cutting blades that create the proper pressure angles necessary for a particular spline design. As each spline is cut, the machine rotates the shaft to position the cutting head for the next pass.
