BONDED ABRASIVES
Resinoid Grinding Wheels & Vitrified Grinding Wheels
These are divided into Vitrified, Resinoid Thin Wheels and are 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 305 mm. Bonded abrasives are mostly in the form of wheels but also in other shapes such as segments, sticks etc. Bonded abrasives for internal purposes classified as Standard Products i.e. those products which are made to standard dimensions, grit sizes, shapes and grain / bond composition.
Non Standard Products are those products which are made to exact requirements of customers. Bonded Abrasives are used in diverse applications like floor polishing, fabrication, polishing, off-hand tool grinding and precision grinding of diverse products like crank shaft, cam shaft across a wide spectrum of industries ranging from automobile, construction, fabrication, steel, bearing etc,,
