Description

Technical Field

[0001] This utility model relates to the field of grinding wheel technology, and in particular to a novel resin grinding wheel. Background Technology

[0002] Currently, both domestic and international resin grinding wheels and rubber grinding wheels are formed using a monolithic pressing method. Monolithic pressing grinding wheels have many drawbacks. First, they have a high density and are too heavy, making loading and unloading difficult for operators and placing a heavy load on equipment, which can cause significant damage. Second, a large portion of the grinding wheel remains after use and cannot be completely disposed of. This leftover grinding wheel scrap is difficult to handle and cannot be reused, causing environmental pollution. Therefore, to address these problems for grinding wheel manufacturers, there is an urgent need for a new type of resin grinding wheel that can reduce weight, facilitate loading and unloading, reduce equipment load and damage, and be recyclable, thus minimizing environmental pollution.

[0003] Currently, the grinding wheels sold on the market with a substrate are all superhard grinding wheels, and the substrate of superhard grinding wheels is a metal substrate, either steel or aluminum. Such metal grinding wheel substrates are relatively heavy and cannot meet users' requirements for lightweight grinding wheels. Therefore, this utility model produces a new type of resin that can completely solve the user's needs. Utility Model Content
