Embodiment Construction

[0015] like figure 1 As shown, the segment mold 1 used in the preparation of the diamond fiber grinding wheel of the present invention is arranged in a circumferential direction with multiple rows of small holes 2 for fixing the diamond fibers. like figure 2 As shown, during the preparation process of the diamond fiber grinding wheel segment, the diamond fibers 3 are artificially arranged in the small hole 2 of the segment mold 1, and the sand tire body material 4 is filled in the segment mold 1, and the hot press molding process is used to prepare the Diamond fiber grinding wheel segments.

[0016] The preparation process of described diamond fiber grinding wheel is as follows:

[0017] The prepared strip-shaped diamond fibers are artificially arranged in the small holes of the block mold and bonded and fixed. In the process of artificially arranging the diamond fibers, in order to ensure the radiation distribution and equal height of all diamond fibers as much as possible...

Abstract

The invention discloses a preparation method for a diamond fiber grinding wheel and a section mold. The preparation method for the diamond fiber grinding wheel comprises the following steps: step 1, preparing a grinding wheel section: uniformly fixing strip-shaped diamond fiber to the periphery of the designed section mold, wherein one end of the diamond fiber points to the center of the section mold in radiation arrangement, then adding section mold to the carcass material to perform hot press formation, so that the grinding wheel section is prepared; step 2, performing overall hot press formation for the grinding wheel section: performing hot press formation for a plurality of grinding wheel sections and grinding wheel base material to obtain the diamond fiber grinding wheel. A plurality of rows of small holes are formed in the periphery of the section mold provided by the invention; the prepared diamond grinding wheel has a long service life, the diamond cannot fall off easily, the scrap containing capacity and dissipation capacity are increased, and heat damage of the workpiece can be effectively avoided or reduced.

Description

technical field [0001] The invention belongs to the technical field of abrasive tools, and in particular relates to a method for preparing a diamond fiber grinding wheel for grinding and a node mold for processing. Background technique [0002] The traditional bonded abrasive grinding wheel has the disadvantages that the abrasive grains are easy to fall off, the grinding temperature is high, it is easy to clog when processing plastic metal materials, and it needs regular sharpening; Limited, the rotation accuracy and geometric shape accuracy of the grinding wheel are severely restricted by the manufacturing accuracy of the grinding wheel base itself, and the waste liquid pollution in the electroplating process; Al 2 o 3 Al exists in fiber grinding wheel and SiC whisker grinding wheel 2 o 3 The fiber / SiC whisker itself has limited rigidity and strength, which cannot meet the needs of precision machining of superhard materials; while brazed grinding wheels are mainly limite...
