Application of diamond grinding wheel in high speed railway track plate processing

The rail plays the role of guiding the vehicle and transmitting the load to the subgrade.  After the high-speed and heavy-duty railway was put into operation, various surface injuries of rail appeared, such as corrugation wear of rail, abrasion of rail surface, strip of rail surface, severe wear of rail side, crack and crush of rail head, etc. And the development speed was fast, which affected the railway transportation capacity and economic benefit.

Analysis of cause and solution of edge breakage in Wafer cutting

A wafer goes through three changes before it becomes a real semiconductor chip:

First, semiconductor chip is cut from a lump of ingots into wafers.

In the second step, a transistor is engraved on the front of the wafer by the previous step.

The importance of binder

Abrasive is generally composed of abrasive, bond and porosity, these three parts are often called the three elements of the consolidated abrasive. Abrasives have a cutting effect in abrasives. A bond is a material that cements loose abrasives into abrasives.

Grinding quality of PCD tool with diamond wheel

PCD tool must ensure good cutting edge before machining workpiece. Diamond grinding wheel is the most widely used method.  The higher the quality of the cutting edge, the finer the tool mark left at the junction of the geometric reflection region of the workpiece surface, and the higher the surface finish of the workpiece.  Because cutting edge collapse or expansion easily cause tool wear or damage, reduce tool life.  Edge collapse is a key index of edge quality of diamond tools.
