Custom CNC Turned Zinc Plated Solid Shafts
Tingfeng Hardware specializes in custom drawing CNC turned zinc plated solid shafts for home appliance motors and various transmission systems. Using high-quality carbon steel or alloy steel, we manufacture high-precision, high-reliability shaft components through precision CNC turning, knurling, and flange forming processes.
Product Overview
Solid transmission shafts are core components for home appliance motors and rotating equipment. Our products achieve strict dimensional tolerance control through precision CNC turning; knurling process provides reliable press-fit or gripping surfaces; flange structure design ensures axial positioning and torque transmission stability.
