What Is Milling and Grinding in Optical Fabrication?
In optical fabrication, milling and grinding (often written as "mill-grind") is the rough machining process

The Problem: Every Grinding Wheel Dulls Eventually
During grinding, every grinding wheel gradually loses its cutting edge. Abrasive grains become dull and flatt

In the precision machining of molds, punches, carbide cutting tools, and complex curved components, optical curve grinders (also known as optical profile grinde

What Is Grinding Wheel Grooving?
Grinding wheel grooving—also called slotting or serrating—is the process of cutting narrow, precision channels into

What Is a Diamond Rotary Dresser and Why Proper Installation Matters
A diamond rotary dresser—also called a diamond roller or rotary diamond dressing roll

Optical profile grinders (also known as PG grinders or optical curve grinders) are high-precision form-grinding machines that use optical projection magnification to machine complex curves, irregular contours, narrow slots, and internal/external radii to micron-level accuracy. They are widely used for precision molds (punches and dies), carbide tools, tungsten carbide components, connector terminals, LED/IC parts, and other high-precision workpieces. Correct grinding wheel selection directly determines machining accuracy, surface roughness, efficiency, and wheel life.
