關于 金剛石金屬結合劑砂輪 的詳細介紹:
The invention of glass is arguably one of the most important and useful discoveries in our history. Glass provides us with aesthetics and the ability to see beyond closed and limited space. Glass is used in every corner of the world for innumerable applications.

Life without glass would be unimaginable.
The endless applications and shapes of glass products are made possible by the use of special tools. The manufacture of glass for any application is obviously a delicate process and not as easy as one may think. Special metal-bonded diamond wheels were invented to grind and shape various kinds of glass. These tools are designed to effectively and efficiently grind glass for uses such as television braun tubes, auto-glass, architectural glass, lens glass, etc.
