Description

Technical Field

[0001] This application relates to the technical field of grinding wheels, and particularly to an ultra-high-speed grinding wheel that is convenient to replace. Background Art

[0002] A grinding wheel, also known as a vitrified grinding tool, is a vitrified grinding tool in which ordinary abrasives are solidified into a certain shape (mostly circular with a through hole in the center) by a binder and has a certain strength. It generally consists of abrasives, a binder, and pores. These three parts are often referred to as the three elements of a vitrified grinding tool. According to different classifications of binders, common ones include ceramic (binder) grinding wheels, resin (binder) grinding wheels, and rubber (binder) grinding wheels. Grinding wheels are the most widely used and applied type of grinding tools. When in use, they rotate at high speed and can be used for rough grinding, semi-finishing grinding, and finishing grinding of the outer circle, inner circle, plane, and various profiles of metal or non-metal workpieces, as well as grooving and cutting.

[0003] Traditional grinding wheels adopt a single integrated structure. When the grinding wheel wears and needs to be replaced, not only is it extremely time-consuming but also the cost is relatively high. Therefore, the replacement of the grinding wheel becomes more complex and inefficient, thereby increasing the maintenance cost and time cost.

[0004] For this reason, this application proposes an ultra-high-speed grinding wheel that is convenient to replace. Utility Model Content

It can be manually disassembled and installed without the need to carry tools with you, which not only saves time but also reduces costs. Therefore, the replacement of the grinding wheel body 1 is made more convenient and efficient, thereby reducing the maintenance cost and time cost.
