The flywheel connects your engine to the clutch of your car’s manual transmission, but it has to be flat to operate smoothly. When the clutch is replaced, the flywheel will often need to be ground down to a uniform thickness across the entire wheel

CBN Flywheel Grinding Wheels are Very aggressive cutting, takes 1/4 of the time of a stone wheel. No dressing, the coolant stays cleaner, longer. Does Corner Cutting, no tool switching, saves time. CBN last tens times longer than the stone wheels.

CBN Flywheel Grinding Wheels are a relatively new addition to the flywheel grinding arsenal. Since they are so new, there’s been some confusion about them that we’d like to clear up.

CBN Flywheel Grinding Wheels are constructed as an aluminum cup (type 11) with CBN (cubic boron nitride) material cemented to the flair.

CBN Flywheel Grinding Wheels are recommended only for use on ferrous materials; specifically cast iron or Steel.

Because there is no real porosity in the CBN Flywheel Grinding Wheel, use them with large amounts of clean flywheel grinding coolant pointed at the wheel contact area. This will lubricate, cool and carry away swarf created during grinding. We also suggest you use a filter sock on the coolant returning to the sump to help minimize swarf returning to the wheel through the sump. Never crowd the machine or use a power feed while grinding as this will build heat and chunk the wheel.
