Cold rolling mandrel
Involute spline mandrel 1. Structure: with cooling system/without cooling system 2. Size range: diameter 10mm-120mm Length 500mm-9000m 3. Material: 40CrNiMo is selected, and after special treatment, it adopts the form of involute spline. When used under high speed, high torque, and high load conditions, nitrogen-containing martensitic stainless steel WR15E and WR30 materials can also be used to give them good toughness and mechanical properties. The accuracy is strictly controlled during the processing process to ensure that the groove depth and groove distance of the mandrel are standard, the surface is smooth, tough and durable.
