There are many types of grinding wheels. Today, our grinding wheel knowledge lecture hall will focus on popularizing the differences between resin grinding wheels and ceramic grinding wheels:
Grinding wheel is a porous body made by adding binder to abrasive, compact, drying and roasting, which can be coarse grinding, semi-fine grinding and fine grinding of the outer circle, inner circle, plane and various profiles of metal or non-metal workpiece, as well as grooving and cutting. Because of the different abrasive, binder and manufacturing process, the characteristics of grinding wheel are very different, so it has an important impact on the grinding quality, productivity and economy.
What are the different characteristics of resin grinding wheel and ceramic grinding wheel?
1, from the color, ceramic grinding wheel according to the material is different, generally blue, white, red, green, black, etc., resin is generally dark brown.
2, from the smell, ceramic grinding wheel is generally tasteless, resin grinding wheel has resin tartaric acid odor.
3, from the sound, the ceramic grinding wheel generally makes a crisp sound when tapping, and the sound made by the resin grinding wheel is more dumb and low.
4, resin grinding wheel and ceramic grinding wheel is the bond of the grinding wheel is different. In terms of the nature of the binder, the ceramic binder is an inorganic binder, while the resin binder is an organic binder.
Therefore, the nature and use of these two grinding wheels are different:
1) Ceramic grinding wheel: Because its bond is ceramic, its chemical composition is stable, heat resistant, water resistant, strong, but brittle. Such as cylindrical grinding machine, surface grinding machine, because the grinding wheel will produce a lot of heat when working, so it is better to wash with water to cool, with ceramic bonding agent.
2) Resin grinding wheel: resin is an organic binder, so it has high elasticity and strength. But the robustness, heat resistance, corrosion resistance is poor. When the grinding wheel uses the end face for grinding, the resin grinding wheel is selected; When cutting materials, you can select a thin sheet resin bonded grinding wheel; When the grinding wheel speed is high, the resin bond grinding wheel is selected.
our grinding wheel raw materials are all directly supplied by international and domestic high-quality manufacturers, to ensure the stability of materials, production and heat treatment are all completed by the factory, through the whole process control to ensure the size of the product, characteristics, life https://www.xfabrasive.com/vitrified-grinding-wheel/
