The Mechanism of Dicing. During the silicon wafer dicing process, the silicon wafer is divided into single units, or dice (Figure 1).1 A rotating abrasive disc (blade) performs the dicing, while a spindle at high speed, 30,000 to 60,000 rpm (linear speeds of 83 to 175 m/sec), rotates the blade. The blade is made of abrasive grit, diamonds, that ...

This material containing 6mm stone chippings is what we use on new and existing footway reconstruction. We also use 10mm stone on low speed, low stress roads. It is laid 20-30mm thick and typically costs £25 per square metre. Hot Rolled Asphalt (HRA) with pre-coated chippings This is the preferred material on heavier trafficked roads.

Keep An Eye on Chip Formation. Inspecting what comes out of the hole is just as important as inspecting the hole itself. Take a look at your chips. As with other machining operations, ones shaped like Cs and 9s are ideal, as are the tight conical chips formed by the center of a smoothly cutting drill. Long, irregular chips, nests, or chips ...
