Embodiment Construction

[0025] refer to figure 1 and figure 2 In one embodiment, a resin-consolidated diamond micropowder phyllotaxy grinding disc includes a resin matrix layer 1 and a resin-diamond micropowder working layer 2 disposed on the resin matrix layer 1 . The resin-diamond micropowder working layer 2 includes a connecting sublayer 21 and several columnar structures 22 arranged in phyllotaxy. The connecting sublayer 21 is covered on the resin matrix layer 1, and the plurality of columnar structures 22 are arranged on the connecting sublayer 21 at intervals, that is, the resin-diamond micropowder working layer 2 part is Continuous layered, partially formed columnar phyllotaxy. The phyllotaxy arrangement of the columnar structure 21 satisfies the trajectory uniformity theory based on the H.Vogel plane phyllotaxy model, that is, satisfies: where θ and r are the polar angle and polar radius of the nth columnar structure, respectively. The columnar phyllotaxy structure has the characteristi...

Abstract

The invention relates to a resin concretion diamond micro-powder phyllotaxy grinding disc. The grinding disc comprises a resin base layer and a resin-diamond micro-powder working layer, the resin-diamond micro-powder working layer at least partially forms a columnar phyllotaxy structure, and phyllotaxy arrangement of the columnar structure meets a track uniformity theory based on H.Vogel plane phyllotaxy model. The invention further provides a manufacturing method of the above grinding disc. A partially-cured resin base layer is firstly formed; secondly, a partially-cured resin-diamond micro-powder layer is formed on the partially-cured resin base layer; a phyllotaxy pressing plate with above phyllotaxy arrangement cylinder holes is pressed on the resin-diamond micro-powder layer so that the corresponding columnar phyllotaxy structure can be at least partially formed; and finally, curing is carried out. The grinding disc has the effects of being even in grinding track distribution and smooth in cooling liquid flowing, ground scraps formed in the machining process can be discharged in time, the grinding quality and the grinding efficiency can be greatly improved, and the grinding disc is prevented from being blocked. The manufacturing method is simple and practicable.

Description

technical field [0001] The invention relates to a diamond micropowder grinding disc, in particular to a resin-solidified diamond micropowder phyllotaxy grinding disc whose surface is arranged according to the theory of uniform trajectory and phyllotaxy and its manufacturing method. Background technique [0002] Grinding and polishing of fixed abrasives is an important technical method for obtaining high-efficiency flatness of ceramic materials, optical crystal materials and semiconductor substrate materials. As the main consumable in the grinding and polishing process, the grinding disc plays a key role. Resin has certain elasticity and good self-sharpening; diamond has high hardness, high strength and excellent chemical stability, and the resin diamond grinding disc prepared by combining the two has good machinability and high cost performance. Therefore, the resin diamond micropowder grinding disc has become an indispensable grinding tool for processing various materials s...
