ON THE INFLUENCE OF OPERATING CHARACTERISTICS OF GRINDED WHEELS ON THE QUALITY INDICATORS OF GRINDED PARTS

Abstract

The quality of the surfaces of roller bearing parts is formed in the process of interaction of the cutting tool with the surfaces to be treated. In addition to technological factors, a significant place in providing a quality surface layer is occupied by the correct choice of grinding wheels.

The abrasive tool has different properties depending on its characteristics. When choosing an abrasive tool, it is necessary to take into account its characteristics and their suitability for a particular type of work. Stable operation of abrasive wheels depends on the correct choice of their size, characteristics and modes of operation.

The selection of grinding wheels depends on the type and properties of machined materials, power of grinding machines, spindle speed, grinding mode, requirements for accuracy and surface cleanliness and other factors that apply to the workpieces.

Depending on the accuracy requirements for machining parts made of different materials, the characteristics of abrasive wheels are selected, the main of which are hardness, grain size, bond, structure, shape, size and allowable speed.
