Super-hard abrasive grinding wheel for fingerprint identification lock substrate grinding and preparation method thereof
The invention provides a super-hard abrasive grinding wheel for fingerprint identification lock substrate grinding. The super-hard abrasive grinding wheel comprises a grinding wheel base body and a super-hard grinding layer; and the super-hard grinding layer is of an annular structure and is bonded to the grinding wheel base body, the grinding wheel base body is a soft elastic base body with the medium-low elastic modulus, and the super-hard grinding layer is a layer prepared by mixing a super-hard abrasive, a functional filler and a resin binder. The soft elastic base body with the medium andlow elastic modulus can buffer the surface of a ground material well, during grinding, under the action of counter-acting force of a workpiece, elastic deformation can occur, thus the abrasive can well adapt to the change of the feed amount and is not so deep as to be pressed into a fingerprint substrate material, the effects of flexible grinding and polishing are achieved, and finally the fingerprint lock substrate material reaches the extremely high surface smoothness and the extremely low thickness deviation.
一种用于指纹识别锁基板磨削的超硬磨料砂轮，包括砂轮基体和超硬磨削层，所述超硬磨削层为环状结构，超硬磨削层粘接在砂轮基体上，砂轮基体为具有中低弹性模量的软弹性基体，超硬磨削层为超硬磨料、功能填料和树脂粘结剂混合制成的层体。本发明的中低弹性模量的软弹性基体能够很好的对磨削材料表面产生缓冲，磨削时在工件反作力的作用下，能够发生弹性形变，使磨料能够很好的顺应进刀量的变化，不至于过度深压进指纹基板材料，从而达到柔性磨削和抛光的作用，最终使指纹锁基板材料达到极高的表面光洁度和极低的厚度偏差。
