What should we pay attention to in the use of diamond cutting tools

Diamond tools are different from other tools. There are certain difficulties in operation, which requires us to be more careful when using. The following Xiaobian will take you to understand what should be paid attention to when using diamond tools.
1. Before using the new diamond tool, it should be withdrawn from the feed of the last dressing. Many brittle diamond cutting tools are easy to be damaged in the initial contact with the grinding wheel. When placing the diamond tool on the clamp seat, be careful not to hit the grinding wheel surface.
2. Do not "quench" the diamond tool with fever (referring to sudden cooling). In dry dressing, it is necessary to maintain a time interval between dressing to cool the hot diamond tool.
3. When diamond cutting tools are used to process iron group materials, the heat generated by friction will make carbon atoms in diamond diffuse to iron, resulting in premature failure of diamond coating due to chemical wear.
4, pay attention to a slight amount of repair. Larger depth of trim, for rough trim: 0.001-0.002 in. For finishing: 0.0005-0.001 inches. If possible, each grinding wheel should not be trimmed more than 0.001 "in the radius of the grinding wheel. Excessive removal can cause premature wear and frequent breakage of diamond tool head.
5. It is not possible to choose too large repair amount and too fast transverse feed speed in rough dressing, and then choose small repair amount and slow transverse feed speed in fine dressing. This will damage the diamond tool very quickly. If possible, it is recommended that the same lateral feed rate be used for rough and finish dressing.
