What is a Grinding Wheel?
์ฐ์ญ ์ง์์ด๋ ๋ฌด์์ผ๊น์? ๐ค
Grinding wheel is indispensable for precisely machining metals, ceramics, and other materials. Itโs more than just a stone; itโs a sophisticated assembly of cutting grains bonded together by a matrix, or binder, specifically designed for optimal performance in material removal.
The structure and performance of a grinding wheel depend heavily on its three main elements: Abrasive grains, Bond material, and Pores.
Each of these has a unique role, and they work together to affect the final product's grinding process, efficiency, and quality.

Main Components of Grinding Wheel
์ฐ์ญ ์ง์์ ์ฃผ์ ๊ตฌ์ฑ์์
The performance of a grinding wheel is determined by five key factors: abrasive grains, grain size, grade, structure, and bond. Each of these components plays a unique role, and different combinations of these factors alter the wheel's usage and performance.
