Coated abrasive machine methods

The widespread commercial use of both coated and bonded abrasives has been very dependent on machine development, although these tools evolved on the basis of hand methods which are still in use. A grinding wheel (or a coated abrasive belt) must be mounted on a machine, however simple or complex, in order to have it perform its basic function. 

Surface preparation is of prime importance, and optimum performance of modern protection coatings can be achieved only if the surface of the steel has been adequately treated. The method of surface preparation depends on the shape and size of the structure or component. Thus it is preferable to blast-clean an openwork steel structure by manual methods, since with this type of structure automatic blast cleaning would lead to excessive impingement of the abrasive on the machine itself.
