Also known as consolidation abrasive, grinding wheel is a kind of consolidation abrasive with certain strength, which consolidates ordinary abrasive into a certain shape (most of which are circular, and there is a through hole in the center) by bonding agent
It is generally composed of abrasive, bonding agent and air hole
These three parts are often called a kind of consolidation abrasive
When used, they rotate at high speed, and can rough, semi fine and fine grind the outer circle, inner circle, plane and various profiles of metal or non-metal workpiece, as well as notch and cut
Summary of grinding wheel
Grinding wheel is the most important kind of grinding tool in grinding
Grinding wheel is a porous body which is made by pressing, drying and calcining the abrasive with binder
Because of the different abrasives, binders and manufacturing technologies, the characteristics of grinding wheels are very different, which has a major impact on the machining quality, productivity and economy of grinding
The characteristics of grinding wheel are mainly determined by abrasive, particle size, binder, hardness, structure, shape and scale
Classification of grinding wheels
There are many kinds of grinding wheels
According to the abrasive used, it can be divided into ordinary abrasive (corundum, silicon carbide, etc
) grinding wheel and natural abrasive superhard abrasive (diamond, cubic boron nitride, etc
) grinding wheel; According to the shape, it can be divided into flat grinding wheel, bevel grinding wheel, cylindrical grinding wheel, cup-shaped grinding wheel, disc-shaped grinding wheel, etc; According to the bond, it can be divided into ceramic grinding wheel, resin grinding wheel, rubber grinding wheel, metal grinding wheel, etc
The characteristic parameters of grinding wheel mainly include abrasive, particle size, hardness, binder, shape, size, etc
Since the grinding wheel usually works at high speed, a rotation test (to ensure that the grinding wheel will not break under the working speed) and a static balance test (to prevent vibration of the machine tool during operation) shall be carried out before use
After working for a period of time, the grinding wheel shall be trimmed to restore the grinding performance and correct geometry
Grinding wheel action
The grinding wheel is one of the most widely used abrasive tools
It can rotate at high speed and can perform rough grinding, semi fine grinding, fine grinding, slotting and blocking on the outer circle, inner circle, plane and various profiles of metal or non-metal workpiece
The products have been exported to the United States, France, Canada, Indonesia, Russia, Vietnam, and other countries, and have been highly praised by customers
