Elements of double row grinding wheel: abrasives, pores, binders. grinding wheel, also known as bonded abrasive, is a bonded abrasive with a certain shape and thickness of ordinary abrasives.
What is a grinding plate?
What are the requirements for the grain size of the grinding plate and its selection?
How is the grinding wheel made?
The grinding disc is the most important grinding tool in grinding. The grinding wheel is a porous body produced by adding a binder to the abrasive, compacting, drying and calcining. Due to the different abrasives, binders and manufacturing processes, the properties of grinding discs are very different and thus have a significant influence on the machining quality, productivity and economic efficiency of grinding. The characteristics of the grinding wheel are mainly determined by factors such as abrasive, grain size, binder, hardness, structure, shape and size.
The grain size of the grinding disc refers to the size of the grinding grains. Particle size is divided into two categories: abrasive and micro powder. Abrasives with a grain size greater than 40 μm are referred to as abrasive grains. Classification is done according to the screening method and the particle size number is expressed as the number of holes per inch length on the screen through which the abrasive particles pass. A grain like 60# is just dimensioned to fit through a sieve with 60 holes per inch length. For abrasives whose particle size is smaller than 40 μm, this is called micropowder. Classified by microscopic measurement, the particle size number is represented by W followed by the number, and the value according to W represents the actual size of the micro powder. For example, W20 indicates that the actual size of the micropowder is 20 μm.
The grinding wheel is the most important type of grinding tool in grinding. The grinding wheel is a porous body produced by adding a binder to the abrasive, compacting, drying and calcining. Due to the different abrasives, binders and manufacturing processes, the properties of grinding wheels are very different and thus have a significant influence on the machining quality, productivity and economic efficiency of grinding. The characteristics of the grinding wheel are mainly determined by factors such as abrasive, strength, binder, hardness, structure, shape and size. There are many types of grinding wheels. According to the abrasives used, they can be into ordinary abrasives, corundum and silicon carbide, etc., grinding wheels and natural abrasives, super hard abrasives, diamond and cubic are divided; Depending on the shape, they can be divided into flat grinding wheels, conical grinding wheels, cylindrical grinding wheels and pot grinding wheels. Disc grinding wheel and so on; Depending on the binder, it can be used in ceramic grinding wheel, resin grinding wheel, rubber grinding wheel, metal grinding wheel, etc. to be divided. The characteristic parameters of the grinding wheel mainly include abrasive, viscosity, hardness, binder, shape, size, etc. Since the grinding wheel usually works at high speed, the rotation test and static equilibrium test should be carried out before using. grinding wheels should be overhauled to restore grinding performance and correct geometry after a certain period of operation.
