48Z449 - Walter 48-Z-449 Seating Stone for Diamond & CBN Wheels (Pack of 6)

Technical Overview

The Walter 48-Z-449 Seating Stone is a critical abrasive accessory engineered specifically for the maintenance and preparation of superabrasive grinding wheels, including Diamond and Cubic Boron Nitride (CBN) varieties. In precision grinding applications, the bonding matrix of a new wheel can often overshadow the abrasive crystals, or the wheel face may become 'glazed' with workpiece material during operation. This seating stone is formulated with a soft, fine-grade aluminum oxide composition that effectively erodes the bonding material without dislodging the expensive superabrasive grains prematurely.

By applying this stone to the wheel face, operators can 'seat' the wheel—a process that exposes the sharp cutting edges of the diamond or CBN particles—ensuring the wheel performs at its specified material removal rate immediately. It is also essential for periodic dressing to remove loaded material that causes friction and heat buildup. The 48Z449 is supplied in a pack of 6, providing a consistent supply for toolrooms and production floors utilizing high-performance grinding setups. Regular use of this seating stone ensures dimensional accuracy and surface finish quality in grinding operations.
