Cast iron flywheels, brake drums, wheel hubs, differential covers and steering knuckles for trucks and buses. Casting and CNC machining are done within one group, so castability and machinability are reviewed together before tooling is made.
FC300 standard, FCD600 upgrade. Dynamically balanced to G6.3 or better, 100% CMM inspected.
Controlled braking-surface hardness, roundness and runout, and consistent wall thickness.
Machined bearing seats and stud holes to drawing, with verified material strength.
Sealing face flatness and bolt-hole pattern machined to drawing for a leak-free fit.
Kingpin and spindle bores, mounting faces and holes machined to drawing, with verified material strength.
