Description

Technical Field

[0001] This utility model relates to the field of grinding wheel technology, specifically a grinding wheel for grinding. Background Technology

[0002] Grinding wheels, also known as bonded abrasives, are abrasive tools in which ordinary abrasive grains are bonded together with a bonding agent to form a specific shape (mostly circular with a central through-hole) and possess a certain strength. They generally consist of abrasive grains, a bonding agent, and pores; these three parts are often referred to as the three essential elements of bonded abrasives. According to different bonding agents, common types include ceramic (bonded) grinding wheels, resin (bonded) grinding wheels, and rubber (bonded) grinding wheels. Grinding wheels are the most widely used and extensive type of abrasive tool. They rotate at high speeds and can perform rough grinding, semi-finishing, and finish grinding, as well as grooving and cutting, on the outer and inner diameters, planes, and various profiles of metal or non-metal workpieces.

[0003] Grinding wheels inevitably experience friction and wear during operation. If the grinding time is too long, the surface temperature of the grinding wheel will gradually rise, and in severe cases, it may even exceed the temperature during heat treatment, which will cause the following hazards to the working process:

[0004] 1. Affects work quality: Overheating of the grinding wheel will soften the abrasive grains, make the grinding marks on the grinding wheel shallower, accelerate the shedding and breakage of abrasive grains, and thus lead to poor grinding effect of the grinding wheel, resulting in a decrease in the grinding efficiency and quality of the workpiece.

[0005] 2. Shortened service life: Excessive grinding wheel temperature accelerates wheel aging, causing cracks and fractures on the wheel surface. This leads to a shorter wheel lifespan and requires more frequent replacements. This not only wastes time and money but also affects work efficiency.

[0006] 3. Safety Hazards: Overheating of the grinding wheel can cause it to explode, leading to injury. When the grinding wheel explodes, fragments will fly in all directions, potentially causing personal injury and equipment damage in severe cases. Utility Model Content
