A quick peek behind the scenes on a fresh batch of Honda K multi-disc flywheels.
Multi-disc setups don't leave much room for error - stack height and face parallelism have to be dead-on so disengagement feels crisp and holds up under abuse on track. Since bringing our Okuma vertical lathe into the shop earlier this year, machining these heavy steel blanks vertically has been a game-changer.
Swipe backwards through the build process:
01: The math and prep - blueprints, setup sheets
02: Quality check on the surface plate with our Mitutoyo height gauge after our roughing operations
03: Freshly turned multi-disc flywheel coming off the machine
04: Precision vertical turning in action
05: Magnetic lifter loading the blank onto the chuck
06: Where it all started - raw steel billet stock on the pallet
Next up is gear cutting and balancing.
Doing it right in-house so it installs smooth and works right the first time.
