Abstract
A method for dressing a grinding wheel by providing a slurry of liquid and solid particles wherein the particle size is smaller than grain size of the grinding wheel and the particles are free of sharp edges, and blasting the slurry at low pressure through a blasting nozzle onto a surface of the grinding wheel to remove foreign material on the grinding wheel by impact and by cleaning action of the blasted stream.
Claims12
A dressing method for dressing a super-abrasive grinding wheel, comprising the steps of:
- providing a slurry of liquid and solid particles wherein the particle size is smaller than grain size of the grinding wheel and the particles are free of sharp edges and wherein the solid particles are synthetic resin with a specific density in the range of 1.0 to 1.5 and a Mohs scale hardness in the range of 3.0 to 4.0, and blasting the slurry at low pressure through a blasting nozzle onto a surface of the grinding wheel to remove foreign material on the grinding wheel by impact and by cleaning action of the blasted stream.
A process for dressing super-abrasive grinding wheels, specifically a vitrified bonded grinding wheel, comprising the steps of:
- providing a quantity of small solid particles which are free of sharp exterior edges, providing a predetermined quantity of a liquid having a viscosity equal to or similar to that of water, joining the predetermined quantities of solid particles and liquid to form a mixture, injecting air into the mixture to agitate the mixture of create a slurry, maintaining the slurry in a closed pressure vessel at a pressure in the range of from about 2.5 to about 3.5 kgf/cm.cm., inducing the pressurized slurry into a slurry chamber of a blasting gun, mixing the slurry in the slurry chamber with an air blasting jet passing therethrough, and directing a slurry-air jet stream discharged from the blasting gun against the working surface of a rotating super-abrasive grinding wheel to effect removal of contaminates therefrom.
