Problems solved by technology

The through tooth has the function of intermittent grinding and good chip removal, but the water utilization rate is low, and it is easy to cause chipping of the processed material; the inner tooth has water storage capacity, the cooling effect is good, but the chip removal ability is poor; the outer tooth has a broken Continuous grinding function, but poor cooling capacity
When the grinding wheel rotates at a high speed, due to the effect of the airflow barrier, the cooling water is more likely to ineffectively leak out from the tooth groove away from the grinding surface, and the proportion of the effect on the grinding surface is extremely small, resulting in extremely low utilization of cooling water, cooling water It is more likely to flow out from the inner tooth groove near the outer ring, causing the inner ring part to be mainly affected by the cooling of the atomized water, that is, the relative lack of cooling; when the wheel ring width is wider, the above-mentioned similar problems are also prone to occur
When using high-speed, fine-grained abrasives for grinding, the above problems can easily cause burns to the workpiece or abrasives and limit high-quality, high-efficiency grinding, thereby limiting the development of grinding technology

Abstract

The invention relates to a composite structure cup-shaped grinding wheel which comprises a grinding wheel base body and a diamond working ring fixedly connected to the grinding wheel base body. The diamond working ring comprises a plurality of tooth sets, and the tooth sets are sequentially and fixedly arranged along the edge of the grinding wheel base body. A first composite tooth groove is formed between each tooth set and the adjacent tooth set. Compared with the prior art, the chip removal function and the cooling function of the diamond working ring can be improved, the utilization rate of cooling water is increased, the cooling effect of the cooling water on an inner ring part is enhanced, the intermittent grinding function is improved, the negative effect of through tooth vibration is weakened, and the quality can be guaranteed while the grinding efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of grinding wheels, in particular to a cup-shaped grinding wheel with a composite structure. Background technique [0002] In the prior art, a cup-shaped edging wheel generally refers to a grinding surface whose width is smaller than the diameter or radius of the grinding wheel. At present, the diamond cup-shaped edging wheel is divided into two categories: toothed and non-toothed. Toothed grinding wheels, the common settings are: through teeth, inner teeth, outer teeth and other structures. The through tooth has the function of intermittent grinding and good chip removal, but the water utilization rate is low, and it is easy to cause chipping of the processed material; the inner tooth has water storage capacity, the cooling effect is good, but the chip removal ability is poor; the outer tooth has the broken Continuous grinding function, but poor cooling capacity. When the grinding wheel rotates at a high ...
