Abstract

The invention discloses an intensified abrasive machining method for a mechanical surface. The method comprises the following steps of: (1) providing a metal workpiece and clamping the metal workpiece on a fixture of a turnplate of a spindle driving device of intensified abrasive machining equipment; (2) providing intensified abrasive and loading the intensified abrasive to a high pressure injection device of the intensified abrasive machining equipment; and (3) injecting the intensified abrasive onto the surface of the rotating metal workpiece through the high pressure injection device of the intensified abrasive machining equipment to perform intensified abrasive machining. When the method is used to process mechanical parts, the method enhances the surface hardness of a metal machined part, effectively improves the surface quality and prolongs the fatigue life.

Description

technical field [0001] The invention belongs to the technical field of mechanical surface processing, and in particular relates to a method for intensified grinding processing of the surface of a metal workpiece. Background technique [0002] The rapid development of modern industrialization and automation has put forward higher requirements for the quality of the mechanical surface. The quality of the surface not only affects the appearance of the product, but also directly affects the life and reliability of the product and even the entire mechanical equipment. In aviation, aerospace equipment, national defense, and military equipment, the failure of a key component may cause the entire equipment to fail to operate, and even cause serious accidents and disasters. Therefore, mechanical surface intensive grinding has become a necessary means for surface processing of some key parts in engineering machinery, precision instruments, medical equipment, especially aviation, aeros...
