What type abrasive wheel is used for grinding cemented carbides?

Resin bond Conventional abrasive resin bonded wheels are widely used for heavy duty grinding because of their ability to withstand shock load. This bond is also known for its vibration absorbing characteristics and finds its use with diamond and cBN in grinding of cemented carbide and steel respectively.

What is abrasive grinding wheel?

In a grinding wheel, the abrasive performs the same function as the teeth in a saw. But unlike a saw, which has teeth only on its edge, the grinding wheel has abrasive grains distributed throughout the wheel. Thousands of these hard, tough grains move against the workpiece to cut away tiny chips of material.

Which grit size is used for rough grinding?

An abrasive grit size of 180-240 [P180-P280] is coarse enough to use on specimen surfaces sectioned by an abrasive wheel. Hack-sawed, bandsawed, or other rough surfaces usually require abrasive grit sizes in the range of 120-180 grit [P120-P180}.

What is the purpose of grinding and polishing the sample?

Grinding is the first step of mechanical material removal. The goal is a plane surface with minimal damage that can easily be removed during polishing in the shortest possible time. Grinding removes material using fixed abrasive particles that produce chips of the specimen material (see below).

What is the main purpose of polishing operation?

Polishing is often used to enhance the appearance of an item, prevent contamination of instruments, remove oxidation, create a reflective surface, or prevent corrosion in pipes.
