Technical Field

The utility model mainly relates to the technical field of needle tip polishing equipment, in particular to a polishing equipment used for needle tip processing.

Background technique

Polishing equipment refers to a machine that is specially used to rub the surface of an object (such as gold or iron) to make the surface smooth. For example, there are various polishing machines on the market, such as tray centrifugal polishing machines and ultrasonic polishing machines, which are all mechanical equipment for processing the surface of objects. In the process of processing the needle tip, polishing equipment is needed for polishing and grinding. The polishing of the needle tip is mainly completed through rough processing and fine processing.

The existing needle tip polishing equipment mainly uses resin grinding wheels for grinding and polishing, because the resin grinding wheels have good elastic polishing performance and self-sharpening, high efficiency during grinding, and high fault tolerance, which is suitable for operations in places with high precision requirements such as needle tips. However, once the temperature of this grinding wheel is high during the grinding process, the grit will easily fall off, the grinding wheel loses its correct shape and cannot be used. Therefore, in the process of processing the needle tip, it wears out more, resulting in more frequent replacement and higher cost.
