1. Introduction
Mechanical grinders and polishers ( hereinafter referred to as "grinders and polishers" ) are equipment used to grind and polish the surface of workpieces. They are widely used in the surface treatment of various materials such as metals, wood, glass, and ceramics. Grinders and polishers can be divided into many types according to different working principles and application scenarios . Understanding the major categories of mechanical grinders and polishers , their characteristics, applicable scenarios, advantages and disadvantages, is crucial for choosing the right grinding and polishing equipment.
