Abstract

The invention discloses a high-precision optical fiber cutting blade and a machining method thereof. The cutting blade is prepared from following raw materials: by weight, 80-100 parts of tungsten carbide powder, 8-10 parts of cobalt powder, 0.5-1.5 parts of beryllium, 0.2-0.5 part of vanadium carbide and 0.4-0.6 part of chromium carbide. The components are weighed as required; the components arefully mixed, the components are put in a mixer to be mixed, and a mixture A is formed; the mixture is smashed, the mixture A is put in an ultrafine smashing machine to be smashed, and a mixture B is obtained; the mixture B is subjected to primary drying, sieving and secondary drying, the mixture B is put in a drier to be subjected to primary drying, then the mixture B passes a 150-300-mesh screen,the mixture B is put in the drier again to be subjected to secondary drying, and a mixture C is prepared; the mixture C is put in a twin-screw extrusion pelleter, and particles D are obtained; the particles D are put in a sintering furnace to be sintered, and a workblank E is prepared; and the workblank E is sharpened. The high-precision optical fiber cutting blade has good machining capacity andis long in service life.

Description

technical field [0001] The invention relates to the technical field of optical fiber processing, in particular to a high-precision optical fiber cutting blade and a processing method thereof. Background technique [0002] Optical fiber cleaver is used to cut silica glass optical fiber as thin as human hair. The end of the cut optical fiber is still flat after being magnified hundreds of times before it can be used for device packaging, cold splicing, and discharge fusion splicing. The service life of the existing optical fiber cleaver is limited due to fast wear. Contents of the invention [0003] The object of the present invention is to provide a high-precision optical fiber cutting blade and its processing method, so as to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A high-precision optical fiber cutting blade is composed of the ...
