Grinding (Surface, Cylindrical, Tool & Cutter)

Saint-Gobain Abrasives offers a new line of centerless grinding wheels to its bonded abrasives portfolio. The Norton Century45 centerless bond platform features an exclusive chemistry that greatly improves grain retention in the wheel. Better grain retention means wheels are constructed with more porosity for a given hardness. This translates into wheels having a hard grade with the performance of a softer grade, providing a range of benefits.

Dear Doc: I sell grinding wheels and frequently find myself pulling my hair out when recommending wheels to customers. One customer achieved great success with a resin-bond, 400-mesh diamond wheel when grinding ¾"-dia. carbide endmills. It performed like a "superwheel." I then took that same wheel to a customer who also grinds ¾" carbide endmills on the same machine model with the same coolant and it's a disaster. Why?
