Unique manufacturing solution

Powertrain precision grinding

Vitrified CBN wheels for the high-efficiency precision grinding of ferrous powertrain components

Developments in machine technology are enabling increased speeds and more precise grinding, with Mirka® Cafro's vitrified CBN wheels grinding speeds can approach 140 m/s, with both high material removal and profile stability.

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.

Precision grinding

The daily grind: better, faster, more cost-effective

Mirka® Cafro vitrified CBN superabrasive wheels are the right choice to make your grinding operations more efficient. See the benefits of faster grinding times, improved wheel life, increased dressing intervals, and superior thermal control reflected in a reduced cost per component.

Our vitrified CBN wheels are available in a wide range of customizable dimensions, up to a diameter of 600mm as single-rim wheels and 900mm as segmented. Standard sizes can be produced with an improved delivery time. We offer wheels with steel, bakelite, and carbon fiber bodies.
