Preparation method of high-strength diamond grinding wheel dressing pen

Abstract

The invention discloses a preparation method of a high-strength diamond grinding wheel dressing pen. The preparation method is characterized in that through utilization of the hot pressed sintering technology, polycrystalline diamond is sintered with wolfram carbide (WC) hard alloy as a pen head of the dressing pen. The preparation method includes the detail steps: cleaning the surface of the polycrystalline diamond, weighing and processing powder according to a certain material prescription of the WC hard alloy, sintering the diamond and the hard alloy materials to obtain the pen head of the dressing pen, and then brazing the pen head on a pen rod to obtain the high-strength diamond grinding wheel dressing pen. The grinding wheel dressing pen obtained through the preparation method has the advantages of being good in heat resistance and strength, and capable of meeting the requirement of precise machining, prolonging service life, reducing comprehensive cost, and being strong in process operability, and good in repeatability.

Description

technical field [0001] The present invention relates to a high-strength diamond grinding wheel dressing pen and its preparation method. Specifically, it is a diamond grinding wheel dressing pen whose tip is sintered with artificial polycrystalline diamond material and WC-based hard alloy material and its preparation method. . Background technique [0002] For grinding wheels, the surface of the workpiece is easily stuck by abrasive particles when processing the workpiece, which affects the grinding effect. Therefore need to adopt a kind of grinding wheel dressing pen to remove the grinding debris on the surface of the grinding wheel, so that the sharpness of the grinding wheel can be recovered. Due to the grinding of the grinding wheel and the dressing pen or dressing knife when dressing the grinding wheel, the wear of the nib is relatively large, so diamond is generally used as the nib. However, due to the scarcity of natural diamond resources in our country, especially t...

Problems solved by technology

[0004] Aiming at the deficiencies faced in the current application of diamond grinding wheel dressing pens, the present invention provides a high-strength diamond grinding wheel dressing pen and its preparation method, which solves the problems of high price, insufficient heat resistance and insufficient strength of existing grinding wheel dressing pens

It not only maintains the high hardness and wear resistance of diamond, but also improves the overall heat resistance and strength of the trimming pen tip, and solves the problems of poor mechanical performance caused by the diamond film welding layer and internal deformation caused by cutting heat.
