Several aspects should be paid attention to in the use of diamond wheel dressing:
1), should according to the grinding wheel diameter diamond particle size. In general, the grinding wheel diameter below 100mm, the optional 0.25 carat diamond; grinding wheel diameter of 300 - 400mm, can choose 0.5-1 carat diamond.
2), the diamond is relatively expensive, should check whether the welding firmly before use, so as not to fall. The wheel dressing or continuous cooling, in order to avoid diamond fragmentation.
3), installation angle of diamond is 10 ° -15 °, diamond grinding wheel mounting height should be lower than 1-2mm, and is clamped to the firm, preventing diamond vibration or into the grinding wheel;
4), must according to the processing requirements choose trimming allowance. A rough break, can increase the depth and vertical feed rate; finishing the contrary. Generally do 2-3 times the depth of cut, then the reciprocating dressing again without engagement conditions;
2, diamond dressing pen method: diamond pen is the smaller particles of diamond or diamond powder, alloy with a strong binding force of binding and pressed into a metal bar and made. According to the diamond distribution, diamond pen has three kinds: layered, chain, powdered diamond pen. The use method and diamond knife is same, can replace the diamond wheel dressing in some less demanding process, but the powdered diamond pen is mainly used for fine grinding wheel dressing.
3, roller cutter rolling method: cut blade when multiple sheets made of carburized and quenched steel metal plate. In the shape of a sharp angle, dressing metal disc with the wheel rotates at high speed, and the grinding wheel surface rolling. This tool is only used for plastic coarse trimming large grinding wheel.
4, diamond roller grinding method: we called the diamond roller, the diamond is the tiny particles of uniform adhered on the roller body, generally using electroplating method, roller shape can be made into complex shapes, dressing with high precision. But the price is more expensive, only in the large volume and high value added products in general use grinding, generally not used.
