Grinding Applications

Grinding wheels utilizing bonded cBN for dry grinding of springs feature multiple layers of cBN, resulting in a more consistent finish. Even better results have been obtained with wheel speeds up to 24,000sfpm. To maintain a more consistent finish, the Gardner cBN matrix uses a finer grain for a finer finish right from the start. The spacing between the matrix is filled with a proprietary composition designed to wear at a similar rate as its cBN-bearing matrix. Unlike conventional cBN electroplated wheels that produce a very coarse finish when the wheel is new, the Gardner wheel produces the same fine finish throughout the life of the grinding wheel. The cBN matrix layers have been processed regularly with depths of 1" (25mm).

Also being displayed will be Black Magic disc wheels which are suitable for dry grinding a wide range of spring materials; superabrasive disc wheels for grinding hard or difficult to grind materials including ceramics; and custom designed and engineered wheels using ceramic grain to increase wheel life and reduce dressing.
