Effective Ways to Improve Diamond Saw Blades' Processing

An important contributor of the unstable quality of diamond saw blades is oxidization of metal powder in natural conditions. Although metal powder deoxidization process has been adopted, the process is usually done to the elementary substance before mixing, after which the metal powder should be processed by subsequent handling, including mixing, cold pressing, packing compact, heat pressing, etc. The huge superficial area of the metal powder may result in re-oxidation during the subsequent handling, the consequence of which is especially true in hot and humid areas.

Let's put it this way: a thorough deduction can only be completed before heat pressing process, which is of great necessity; the pre-alloyed powder before hot pressed sintering with a high degree is also essential.

An effective way to solve the problems mentioned above is cold pressing technology for saw blades and high temperature reduction process, which can guarantee the stable performances of each type. A slight difference in the ingredients of saw blades may cause conspicuous discrepancies in cutting tests. The reason for this is that after all the other factors are excluded, a slight adjustment in the ingredients will cause respondent changes in the saw blades' performance.

During the sintered process of diamond saw blade (especially ultrathin diamond saw blades), the first priority should be metal powder oxidization. Unstable quality in saw blades with same ingredients may result from powder oxidization. Cold press deduction process has excluded natural factors and can have metal powder deoxidized thoroughly, which is a guarantee for product stability and quality. The heat process deduction process has been widely used and will definitely improve China's metal adhesives diamond products' quality substantially.
