Why is it necessary to grind after hard turning?
2020-11-30The purpose of grinding as the finishing step is to obtain the surface quality which cannot be achieved by hard machining. Shaft products require high surface quality of bearing mounting position or sealing position. For example, some surfaces require a non-helical surface, which is not possible with hard cars. Some parts are severely discontinuous, and turning can be a quick way to remove the margin. The precision grinding process is then used in the same clamping process in order to precisely grind to the required size and surface quality. Because the margin of grinding after hard lathe machining is very small, the grinding wheel wears lightly, which can reduce the dressing times and improve the processing efficienc

Analysis and solutions of the coating falling off of electroplated diamond tools
2020-11-25With the development of economy and the progress of science and technology, different industries have basically the same requirements for electroplated diamond tools, that is, high efficiency, long life, and high grinding precision. To ensure these characteristics, the coated metal must not only have higher hardness and wear resistance, but also must be evenly distributed in all parts of the substrate to prevent the coating from falling off and shorten the tool life. In some special industries, such as powerful grinding in the magnetic material industry, the feed rate is controlled at about 0.3mm.

New research of ultra-sonic cleaning for diamond grinding wheels
2020-11-24Recently, we have a customer met a problem in his grinding work. He is using our resin bond diamond grinding wheel for this carbide workpiece grinding. The wheel works very good in the beginning, but later, he finds the wheel is blocked by the chippings. Grinding wheel losses grinding ability, becomes dull and grinding efficiency reduced very much. Under this circumstance, he asks me for help. This is a common issue during grinding work, not a big problem, and very easy to control.
