Dimension is (φ75-φ105) x (220-420) constant speed universal joint processing equipment CNC lathe, Its material choice is 40Cr, it forging shaft parts can be based on the use requirements, production type, equipment conditions and structure, the selection of bars, forgings and other blank form.

For the axis with little difference in diameter of outer circle, rod material is generally the main material; Forgings are often used to save materials and reduce the workload of mechanical processing, as well as improve mechanical properties for stepped shafts or important shafts with large diameter differences.

According to the different production scale, the blank forging method has two kinds of free forging and die forging. Small and medium batches of production mostly use free forging, large quantities of mass production using die forging.
