Abstract

The invention relates to a coating hobbing cutter for bimetallic band saw blade gear milling as well as a preparation method and application of the coating hobbing cutter. The coating hobbing cutter comprises a cutter base body and further comprises an AlTiN bonding layer, an AlTiN / V2O5 alternating layer and an AlTiN top layer which are sequentially arranged on the outer surface of the cutter base body; the AlTiN / V2O5 alternating layer is obtained through alternate depositing of AlTiN layers and V2O5 layers. AlTiN is prepared by an arc ion plating technology, and V2O5 is prepared by a magnetron sputtering technology. The invention relates to the application of the coating hobbing cutter. The coating hobbing cutter is mainly applied to gear milling of a bimetallic band saw blade. According to the coating hobbing cutter, the defects of high friction coefficient of AlTiN and low hardness of V2O5 are overcome through a multi-layer structural design, and the coating hobbing cutter which is used for bimetallic band saw blade gear milling, and has excellent mechanical properties, wear resistance, friction reduction and long cutting life is obtained.

Description

technical field [0001] The invention belongs to the field of preparation of coating hob materials for bimetallic band saw blade milling teeth, and in particular relates to a coating hob milling cutter for bimetallic band saw blade tooth milling and its preparation method and application. Background technique [0002] With the gradual acceleration of my country's progress from a big manufacturing country to a powerful manufacturing country, the domestic machinery manufacturing industry has developed rapidly in recent years, and higher requirements have been put forward for the processing efficiency and quality of machinery manufacturing. In the mechanical manufacturing process, the first process of raw material processing is usually blanking, and the processing quality and processing efficiency of this process will affect the entire subsequent processing process. Sawing is one of the most commonly used blanking methods, and the bimetallic band saw blade is the main tool for s...
