Description

Technical Field

[0002] A centerless grinder is a type of grinder that does not require the axis of the workpiece to be positioned for grinding. It is mainly composed of three mechanisms: a grinding wheel, an adjusting wheel, and a workpiece holder. The grinding wheel is actually responsible for grinding, the adjusting wheel controls the rotation of the workpiece and the feed speed of the workpiece, and the workpiece holder supports the workpiece during grinding. These three parts can be coordinated in several ways, but the principles are the same except for stopping grinding.

[0003] Cutting fluid is an industrial liquid used in the process of metal cutting and grinding to cool and lubricate tools and workpieces. Cutting fluid is scientifically compounded from a variety of super-functional additives.

The coolant is used in a way that the coolant is sprayed onto the grinding wheel and the workpiece to be processed by a high-pressure method, wherein the coolant is circulated. While the coolant is sprayed onto the workpiece to be processed to cool it down, it will also take away the iron filings generated by the processing and enter the circulation device. When the coolant is circulated, the iron filings mixed in the coolant will be sprayed onto the workpiece to be processed and the processing equipment together, thereby reducing the processing accuracy and thus affecting the processing quality of the workpiece to be processed.
