Bonded Abrasives

These are divided into vitrified, resinoid and rubber products and manufactured by mixing grains with bonding material, moulding them to shape and then subjecting the output to firing or baking in high temperature and finishing the same to desired dimensions. The composition of the product depends on the type of grains and type of bonding materials used. Sizes will vary between 10 mm to 1200 mm with thickness ranging from 1 mm to 650 mm. Bonded abrasives are mostly in the form of wheels but also in other shapes such as segments, sticks etc. Bonded abrasivesfor internal purposes classified as Standard Products (i.e. those products which are made to standard dimensions, grit sizes, shapes and grain / bond composition).
