New Metal Bond For Superabrasives Has Vitrified Performance Characteristics Meister Abrasives USA will be introducing two new product lines this year based on an advanced bonding technology that provides the durability of a metal bond along with the free-cutting porosity of vitrified products. The first of these products to be introduced in North America are the company’s new hDD Hybrid Diamond Dressing Tools.

The new bonding technology is based on a proprietary manufacturing process that both mechanically and chemically bonds the diamond particles within the tool to insure that they will be held securely. As a result, metal posts or 'bridges' that attach to the diamond crystals in the bonding matrix can be slender, allowing for large pores to be naturally distributed between the crystals.

These slender posts allow the Diamond or CBN particles to stand out from the bonding matrix for improved cutting. The posts also fracture readily to expose a new layer of abrasive when the first layer has worn down to metal. These properties ensure a high level of cutting performance while eliminating the need for periodic conditioning, which is a requirement with all other types of metal bonds.

The hybrid bonding technology is the culmination of a prolonged R&D effort by Meister Abrasives AG in Switzerland. The corporation has now invested heavily in new equipment and a facility devoted entirely to manufacturing hybrid metal bonded abrasive products.
