Grinding wheels have important applications in both industrial and mechanical fields, but there are many kinds of grinding wheels, so how to choose when we use it?
[u]4 inches China grinding disc factory[/u] introduced a selection method of superhard abrasive.
Superhard abrasives are formed by three combinations of abrasive, binder and matrix. It can be seen that the bonding agent is an indispensable part of the production of abrasives, its role is to bond the abrasive into a certain geometry, and hold the abrasive particles in the process of grinding to bear the grinding force and play a cutting role. There are three main kinds of bonding agents for superhard Abrasives: resin bond and vitrified bond. How to choose the appropriate binder is mainly based on its own performance and processing requirements for
[u]abrasive grinding disc tools[/u].
Resin bond: it has a good elasticity and polishing effect, after the formation of abrasives, still has a good self-sharpening, not easy to clog, less dressing, and high grinding efficiency, low grinding temperature, high surface finish grinding, so the scope of application is very wide. Resin bonded diamond abrasives are often used in semi-finishing and finishing grinding of cemented carbide, steel-based cemented carbide and some non-metallic materials.
Vitrified bond: the bond strength of the binder to abrasive is better than that of resin. After the abrasive tool is formed, the chip capacity of the working surface is good, so it is not easy to be blocked, the cutting edge is sharp, the grinding efficiency is high, the thermal expansion is small, and the machining accuracy is easy to control. These characteristics are conducive to the smooth progress of the grinding process. In the aspect of
[u]China abrasive tools for metal[/u] shaping and dressing, it is relatively easy to operate, generally used for rough grinding, semi-finishing grinding, as well as large contact surface molding grinding, etc., so ceramic binder is now increasingly widely used as a binder.
