Dressing Technique for Truing Up Diamond Grinding Wheels ...
This positioning of the dresser wheel axis at a 90-degree angle is the XING dressing technique. "For diamond wheel dressing, the dressing wheel still wears as much as or more than the grinding wheel, but now the dressing wheel is always a perfect radius," Mr. Drechsler says. "So that eliminates one of the huge variables in that process.".
Grinding (abrasive cutting) - Wikipedia
Grinding is a subset of cutting, as grinding is a true metal-cutting process. Each grain of abrasive functions as a microscopic single-point cutting edge (although of high negative rake angle ), and shears a tiny chip that is analogous to what would conventionally be called a "cut" chip (turning, milling, drilling, tapping, etc.).

What is Polishing and Define the Process
A process to generate a reflective surface. Normally, the polish is generated by using a fine-micron or sub-micron abrasive particle in combination with a liquid. Polishing is a "wet" process. Often the polishing process utilizes a pad to contain the abrasive, so polishing may not be a "loose abrasive process.". The pad is softer than ...
