High load and cracking measures for rear wheel differential cases | Cutting of ductile cast iron and mouse.
For those troubled by damage during high torque or distortion of shaft holes! We solve this with robust FCD precision machining, achieving improved drive transmission efficiency and significant cost reduction.
Do you have any of these concerns? - Cracks around the bearing area and bolt holes of the differential case due to high torque loads on the rear wheels. - Long machining times for large cast iron workpieces, creating a bottleneck in the production line. - Poor yield from large integrated machining significantly increases manufacturing costs. Kyowa Seiki's "Precision Machining Contract Service for Rear Wheel Differential Cases" fundamentally resolves these issues. ◇ Precision machining using FCD material for high load capacity ◇ We use a robust ductile cast iron material that withstands harsh driving torque and perform precision machining without leaving distortions from thick to thin sections. ◇ Cost reduction through an approach utilizing the black skin of raw materials ◇ We propose a machining design that intentionally leaves the black skin surface, which contributes to strength reinforcement. This minimizes the amount of material removed, significantly cutting down on material waste and machining costs. ◇ Reliable technology that guarantees geometric tolerances for shaft holes ◇ We maintain high precision in the coaxiality of shaft holes, which affects the meshing of differential gears. This prevents torque transmission loss and unnecessary vibrations and noises. *For more details, please download the catalog or feel free to contact us.
