Description

TECHNICAL FIELD

[0001] The utility model relates to the field of grinding wheel manufacturing, and particularly relates to a grinding wheel for side surface machining of a saw blade with combined coarse and fine particle sizes. BACKGROUND

[0002] Saw blade grinding wheels play a crucial role in metal cutting and grinding processes. Typically, saw blade grinding wheels employ a single particle size, meaning that the abrasive particles across the entire surface of the grinding wheel are uniform in size. While this design is simple to manufacture and relatively low in cost, it may not meet the requirements of high precision and high efficiency in actual use. Therefore, in order to improve the processing quality and efficiency, saw blade grinding wheels often adopt a design of coarse and fine double-layer particle sizes.

[0003] The advantage of double-layer particle size grinding wheels lies in their ability to complete the rough and fine grinding processes in one pass. Specifically, the coarse abrasive particles are located on the outer layer or front end of the grinding wheel, responsible for preliminary cutting and grinding, which can quickly remove material and improve processing efficiency. The fine abrasive particles are located on the inner layer or rear end of the grinding wheel, responsible for fine grinding to ensure the smoothness and dimensional accuracy of the processed surface. This design not only simplifies the processing flow, reduces the multiple clamping and positioning errors of the workpiece, but also improves the overall processing efficiency and accuracy.

[0004] However, there are some problems with double-layer grinding wheels during long-term use. Since the coarse abrasive particles bear greater cutting force and friction force during use, their wear rate is usually faster than that of fine abrasive particles. This means that over time, the coarse abrasive particles may gradually lose their original cutting and grinding ability, leading to a decline in processing quality and efficiency. In contrast, the fine abrasive particles have relatively low wear and tear, and can maintain their fine grinding ability for a longer period of time.

[0005] When the abrasive of the grinding wheel wears to a certain extent, it needs to be trimmed to restore its original shape and grinding performance. For double-layer grinding wheels, the trimming process is often more complex and time-consuming. Due to the difference in wear between coarse and fine abrasive particles, different treatments need to be applied to the two types of abrasive during trimming. This not only increases the trimming time, but also may result in waste of abrasive, especially when the fine abrasive particles have not yet been completely worn out, trimming them may cause unnecessary wear and tear. SUMMARY

[0006] In order to overcome the above-mentioned defects of the prior art, the purpose of the utility model is to provide a grinding wheel for side surface machining of a saw blade with combined coarse and fine particle sizes. The original structure of the coarse and fine grinding wheels is replaced by a split combination structure to reduce unnecessary wear and tear.
