Grinding wheels are abrasive tools that are used to remove a fine layer of material from the surface of the workpiece. This is done to achieve the desired dimensional tolerance and surface finish.
At high speed, rotate the grinding wheel so it comes into contact with the workpiece and removes the material. This high-speed contact can generate high frictional heat (especially when grinding tough metals like stainless steel). This makes it important to use cutting fluid to prevent overheating of the tool and the workpiece.
When using a grinding wheel, always maintain to-and-fro movement between the grinding wheel and the surface of the workpiece. This is required to ensure a smooth and uniform surface finish. Furthermore, when a high volume of material is to be removed, it is advised to gradually grind the workpiece in multiple passes. This is because grinding at the same spot for a prolonged time can result in overheating. Thus damaging the workpiece and the tool.
Common usage of grinding wheels is to grind the workpiece and achieve the desired dimensional accuracy or improve its surface finish. Therefore, it is an important operation that is performed on almost every workpiece before finalizing the machining process.
Common use of grinding is to remove unwanted material or smoothen sharp edges in metalworking industries, and to finish and achieve a smooth surface on jewelry and other intricate works.
Grinding wheels can be classified based on the abrasive and bond type.
Generally, resinoid and rubber are the most commonly used bond types and are used for most general-purpose applications. The vitrified bond provides the strongest adhesion, preventing the abrasive particles from falling off during intense grinding applications.
Similarly, the harder the abrasive, the better the material removal ability of the grinding wheel. Based on the abrasive material, there are four types of grinding wheels:
Aluminium oxide is the most commonly used abrasive on grinding wheels and is best suited for grinding ferrous metals and steel workpieces. These abrasive wheels are colour-coded as grey, white, pink, brown, etc.
Grey and brown are the most widely used wheels for general-purpose grinding applications, as they provide good durability at a low cost. These wheels are ideal for machining low-carbon steel.
Pink and white grinding discs are comparatively harder and are used for grinding tougher grades of steel (such as stainless steel) that generate high frictional heat during the grinding operation.
Apart from these, aluminium oxide grinding wheels are also available in ruby red colour. These wheels are extremely tough and are used for machining tool steel.
Silicon carbide abrasives are ideal for grinding non-ferrous metals like aluminium, copper, etc., and non-metals like marble, granite, etc.
These grinding wheels are available in black and green, with green wheels having better sharpness than black wheels. Silicon carbide wheels are also used for grinding stainless steel when a high-quality surface finish is required.
Ceramic abrasives are relatively new and are not readily available on the market. These abrasives tend to self-sharpen by breaking the dull grains, attaining a renewed sharp cutting edge.
These types of grinding wheels are ideal for applications where extensive material removal is required while maintaining a long tool life. However, ceramic grinding wheels are comparatively expensive and cost around three times more than aluminium oxide abrasive wheels.
Diamond abrasives are ideal for grinding extremely tough materials like concrete, asphalt, stones, etc. These grinding discs can be used on almost any material, but their high-cost limits them from being used for general-purpose applications.
