Manufacturing method and device of brazed diamond tool

Abstract

The invention discloses a manufacturing method and device of a brazed diamond tool and relates to the technical field of tool manufacturing. According to the manufacturing method and equipment of the brazed diamond tool, the defect that the protruding heights of abrasive particles of an existing brazing tool are poor in consistency is overcome, the advantages of an electroplated tool using an inside-plating method is combined, good equal height performance and high precision of tool abrasive particles can be ensured. The manufacturing method comprises the following steps that a moulding bed is manufactured, and the moulding bed is an inner hole moulding bed; diamond abrasive grains are orderly distributed on the surface of an inner hole of the moulding bed; a tool clamp is used for accurate positioning of the moulding bed and a tool basal body, and a gap of 1-2 mm is reserved; the gap is filled with brazing filler metal, and punning is conducted; the moulding bed, the tool basal body and the clamp are perpendicularly placed in a vacuum furnace in the axial direction and heated and brazed; after brazing is completed, the moulding bed, the tool basal body and the clamp are fetched out, and the moulding bed is turned until the thickness is 0.5-1 mm; and the brazing filler metal on the outer layer part of the moulding bed is removed through electrolysis, and the diamond abrasive grains are exposed and serve as cutting edges.

Description

technical field [0001] The invention relates to the technical field of tool manufacturing, in particular to a method and equipment for manufacturing a brazed diamond tool. Background technique [0002] High-strength, tough and difficult-to-machine materials represented by nickel-based superalloys, titanium alloys, and ultra-high-strength steels have a series of advantages such as high plasticity, good toughness, high strength, and high strengthening coefficient. The application in the industry is more and more extensive. Taking the aero-engine in service as an example, superalloys and titanium alloys account for 55-65% and 25-40% of the total weight of the aero-engine respectively. With the continuous improvement of the requirements for the performance, processing quality and efficiency of parts, the problems in the high-efficiency and precision machining of difficult-to-machine materials have attracted more and more attention. [0003] At present, the electroplating proces...
