In the daily machining process, usually said grinding wheel, then to use tools each kind of tool should be used to grind? Also heard what the diamond grinding wheel, cubicborazin etc. How? Wheel what evaluation standard? Assume what use after grinding sheet, should use a tool to repair what?

1 the diamond grinding wheel grinding tool grinding machine suitable for all kinds of tools.

2 most is used manual sharpening alumina grinding wheel and silicon carbide, alumina grinding wheel applicable alloy carbon steel type, such as high speed steel paper cutting knife and cutting tool class drill. Sic grinding wheel for cemented carbide cutting tools.

3 after grinding use groove can use pen repair, diamond grinding can be used to repair, but sticking pieces more at ordinary times when using grinding wheel to minimize appear groove.

4 cubicborazin is mainly used for cutting tools, it is made of high speed cutting than carbide cutting tools.

Question: the first question: the supplement of the grinding wheel granularity, hardness, grinding the bonding strength is different also, is also different.

The second problem: a diamond grinding wheel wear later can such as pens to repair is harder. Practical things he fixed flat, there may be not quite sure about the place, the meaning.
