Vitrified superabrasive wheels

Mirka® Cafro's vitrified superabrasive wheels can be dressed in the operating machine, just as with conventional abrasive wheels. Our broad product range includes continuous rim diameters from 10mm to 605mm, and segmented rims over 900mm in diameter. These vitrified wheels are often customised products, produced to the customer's specific requirements. Standard sizes are available with an expedited delivery time.

The CBN superabrasive used in these wheels is the abrasive of choice for manufacturing ferrous automotive powertrain components, such as camshafts and crankshafts. Replating services are offered for the replacement or renewal of superabrasive rims on valuable steel bodies.
