Abstract
This application relates to the field of tool polishing, and specifically discloses a polishing process for cemented carbide cutting tools, including the following steps: S1, using a cleaning agent to clean the oil on the surface of the tool, and then ultrasonically cleaning the tool; S2, injecting the tool into a passivation polishing machine Add the abrasive and polishing paste with a weight ratio of (2‑5): (0.05‑0.5) and mix well, then start the passivation polishing machine and set the speed at 50‑100r / min, insert the tool into the mixture of abrasive and polishing paste Polishing; S3, after polishing, use clear water spray to clean and dry to obtain the polished tool; the abrasive is a mixture of diamond micropowder, nano silicon dioxide, and boron carbide particles, and the weight ratio of diamond micropowder, nano silicon dioxide, and boron carbide particles is For (0.5‑0.8): (1‑3):3. The present application has the advantage of improving the polishing uniformity of cemented carbide cutting tools.
Description
technical field [0001] The present application relates to the field of tool polishing, more specifically, it relates to a polishing process of cemented carbide cutting tools. Background technique [0002] Carbide cutting tools are one of the most basic processing tools in the machinery manufacturing industry made of cemented carbide. Cemented carbide has become an extremely important tool material in modern society due to its high hardness and strength, high elastic modulus, small thermal expansion coefficient, and high wear resistance. [0003] With the development of ultra-precision machining of precision molds and tools in my country, the quality requirements of cutting tools are getting higher and higher, and improving the surface quality of tools is one of the important means to improve the quality and performance of cemented carbide tools. The surface quality of cemented carbide cutting tools is mainly determined by the polishing process of the tool. Although most of ...
