Production Description:
1.The key points of the bell:
① Raw material: We using CF53 as the raw material of the bell, But most other manufacturer using CF45 replace CF53 in order to can reduce the cost largely.
② Heat treatment process: Bell consisting of the thread, spline and shell. Because the outboard ball joint installing the wheel, it will endure the huge torque and impact force. conjunction of Spline and shell body and inner chamber needing enough strength. So we adopt the most advanced heat treatment process and equipment, we using the medium- frequency induction hardening machine from EFD, Germany, improve product’s toughness and hardness. Longer products life and guarantee car safety Property.
③ Bell’s inner raceway: We purchasing CNC track grinder for CVJ bell outer race from Italy FMT s.r.l. meccanodora. The machine belongs to four axes coordinated. The machine has the characteristics of high automation degree, High Precision, high efficiency, stable quality etc and longer the product’s life. But most manufacturer do not buy this equipment, because its cost is very expensive.
④Bell’s spline: We purchasing milling machine of rolling spline and thread from EX-CELL-O, Germany. The machine has the characteristics of high precision, high efficiency, stable quality. we guarantee products quality, makes the spline even.
