Welcome to the Norton Tech School of Abrasives. Today, we will review how to optimize the grinding parameters when using Norton Paradigm wheels for periphery, form, and top and bottom insert grinding.
Before you can grind tungsten carbide or ceramic inserts, it's important to true and dress the wheel properly. Paradigm wheels online truable bond technology enables easier truing than competitive wheels, and allows the wheels phase to stay open and hold form longer resulting in increased wheel life for more parts progress.
After mounting the Paradigm wheel in your grinding machine, position the truing wheel and Paradigm wheel access perpendicular to each other. Use a Norton 220‑grid or finer silicon carbide or aluminum oxide H grade or softer truing wheel.
Here are some suggested technical parameters.
After preparing your Paradigm wheel you are ready to start grinding. Starting specifications and grinding parameters will depend on which application you are performing. For insert periphery grinding, use the following starting specifications and parameters.
For insert form grinding use the following starting specifications and parameters.
For insert top and bottom grinding use the following starting specifications and parameters.
Paradigm wheels performance is optimized with oil based coolant, but will also work with water soluble coolant. Avoid the use of a high pressure scrubber. It may damage the surface of the wheel and cause premature wear.
Paradigm wheel's natural porosity and fine grid diamond availability increases chip clearance and coolant penetration for a higher material removal rate and better part quality. Further optimization of the grinding parameters of your specific application will result in the highest material removal rate, longest wheel life, and lowest cost per part available today.
