Embodiment Construction

[0012] The superabrasive grinding wheel with phyllotaxy arrangement abrasive end face of the present invention comprises a grinding wheel base body 1, the working surface of the grinding wheel base body 1 has a plurality of abrasive grains 2 conforming to the biological phyllotaxy theory, and the plurality of abrasive grains 2 are fixed on the surface by a nickel bond On the grinding wheel substrate 1. A plurality of abrasive grains 2 form a plurality of counterclockwise alignment grooves 3 and a plurality of clockwise alignment grooves 4 according to the biological phyllotaxy theory.

[0013] Biological phyllotaxy theory H. Vogel model, that is, the polar coordinate angle of the plant grain satisfies , the radial position of the polar coordinates of the grain block satisfies . where n is the ordinal number of the kernel and k is the growth coefficient. The H. Vogel model is a typical model describing the structure and arrangement of sunflower seeds. The arrangement of t...

Abstract

The invention discloses a super-hard abrasive grinding wheel with a head face having abrasives in a phyllotaxis arrangement, comprising a grinding wheel basal body. The working surface of the grinding wheel basal body is provided with a plurality of abrasive particles or abrasive particle groups fitting with the biological phyllotaxis theory. The plurality of abrasive particles or abrasive particle groups are fixed on the grinding wheel basal body through a metal bonding agent. According to the biological phyllotaxis theory, the plurality of abrasive particles or abrasive particle groups forma plurality of anticlockwise leaf column line grooves and a plurality of clockwise leaf column line grooves. By means of the invention, the arrangement of the abrasive particles or the abrasive particle groups on the working surface of the grinding wheel fits with the H.Vogel model of the phyllotaxis theory so as to realize the physiographic controllability of the working surface of the grinding wheel. Nickel or nickel-cobalt alloy is adopted to serve as the bonding agent so as to fixedly bond the abrasives. The grinding wheel is capable of controlling the cutting state of the abrasive particles in a grinding region, the cooling liquid distribution and the grinding temperature distribution, and achieving lowest grinding force and specific energy consumption, lowest grinding temperature and burn, lowest abrasion of the grinding wheel, optimal work-surface surface integrity, and the like. The comprehensive grinding performance of the head face grinding of the super-hard abrasive grinding wheel is improved.

Description

technical field [0001] The invention belongs to the field of high-efficiency precision grinding, and is a novel design and manufacturing method of superhard abrasives. The characteristic of this grinding wheel is that the phyllotaxy theory in biology is applied to the design and manufacture of grinding wheels in the grinding process, so that the surface morphology of the superabrasive grinding wheel for end grinding meets the H. Vogel model of the distribution and arrangement of sunflower seeds. Mainly used in the manufacturing process of grinding optical parts, semiconductor wafers, ceramic parts and difficult-to-machine metal material parts, etc., it can obtain high surface integrity, reduce grinding heat damage, grinding force and specific energy consumption, Improving the service life and grinding efficiency of grinding wheels is of great significance for efficient and precise grinding of precision parts. Background technique [0002] Grinding is an important processing...
