Diamond grinding wheel with lotus seedpod structure and preparation method thereof

Abstract

The invention discloses a diamond grinding wheel with a lotus seedpod structure. The diamond grinding wheel comprises a circular disk-shaped base body, an annular diamond grinding layer and a plurality of resin binder diamond grinding blocks. The outer circumference of the base body is sleeved with the diamond grinding layer. Each resin binder diamond grinding block is provided with a fixed part and a grinding part. The outer circumference of the diamond grinding layer is provided with a plurality of through holes. The grinding parts of the resin binder diamond grinding blocks are inserted into the corresponding through holes. The diamond grinding wheel is good in heat conductivity, more durable and beneficial to improving the surface quality of ground workpieces, and the grinding blocks can be effectively prevented from falling off under the action of grinding force in the grinding process. The invention further discloses the diamond grinding wheel with the lotus seedpod structure anda preparation method thereof. The preparation method comprises the steps of preparing the resin binder diamond grinding blocks, preparing a grinding wheel base body foam model, preparing a grinding wheel overall foam plastic model and other steps. The preparation method is simple in process, preparation is easy, the requirements for the equipment are not high, and the cost can be effectively lowered.

Description

technical field [0001] The invention relates to the technical field of grinding wheel manufacturing, in particular to a diamond grinding wheel with a lotus structure and a preparation method thereof. Background technique [0002] Grinding wheels can be divided into metal-based grinding wheels and non-metal-based grinding wheels. Whether it is metal-based grinding wheels or non-metal-based grinding wheels, the bond of the grinding wheel affects the strength, impact resistance, heat resistance, corrosion resistance, etc. of the grinding wheel, and has a great impact on the grinding wheel. Accuracy and grinding efficiency have a great influence. Non-metallic grinding wheels are represented by phenolic resin. Resin grinding wheels can absorb vibration and impact because of their good elasticity and concession, but they have poor heat resistance and abrasive grains are easy to fall off, and their durability is not high. Metal-based grinding wheels have the characteristics of hig...

AI Technical Summary

Problems solved by technology

When the adhesive bonding structure is used for combination, the bonding strength between the node unit and the grinding wheel base depends on the physical properties of the adhesive, so it is prone to failure, poor corrosion resistance, and automatic fall-off, thereby affecting its grinding performance

[0004] In addition, the existing commonly used grinding wheels not only have many steps in the production process, but also are difficult to process, require high equipment, and are relatively labor-intensive.

Therefore, the production efficiency is low and the cost is high
