Problems solved by technology

[0003] In order to solve the processing problems of large modulus and medium-hard tooth surface gears, and overcome the defect that general tools cannot process relatively hard tooth surfaces, the purpose of the present invention is to provide a hard alloy finishing finger milling cutter and a processing method, so that The tool can improve the machining accuracy of the gear, can cut heat-treated materials with a hardness greater than HB360, and is wear-resistant, which can reduce the number of regrinding of the tool and greatly improve the cutting conditions.

Embodiment Construction

[0014] Such as figure 1 , 2 As shown in and 3: the tungsten carbide finishing finger milling cutter has a cutter body part, and a blade groove is milled on the cutter body, and the long blade and the short blade are welded on the cutter body; YG6X hard alloy plate is selected as the cutting edge For processing materials, 40Cr material is selected as the material of the cutter body. First, the shape of the cutter body and the chip groove are milled, and then a suitable blade groove is milled on the cutter body according to the blade blank. Before welding, the cutter body is preheated to 250°C , keep warm for 30 minutes; use high-frequency welding technology to weld the blade and the cutter body, and then grind out the positioning inner hole and end face, use the sharpening machine to cut the front edge, install the special tire tool to compile the tooth shape processing program based on the front edge surface, The tooth shape is cut out by high-precision slow-moving wire cutti...

Abstract

The present invention is one kind of finger shaped hard alloy milling cutter for finish machining and its machining process. The finger shaped hard alloy milling cutter has four, two long and two short, cutting blades made of YG6X hard alloy plate and one cutter body of 40Cr steel. It is machined through semi finishing of cutting blades, milling the cutter body in a universal milling machine to form blade slots, high frequency welding cutting blades to the cutter body and timely tempering, grinding the front edge of the finger shaped milling cutter in a cutter grinding machine, and wire electrode cutting the tooth form in high precision wire electrode cutting equipment. The finger shaped hard alloy milling cutter has high cutting hardness and high wear resistance, and may be applied for finish machining great modulus gear with medium hardness tooth surface.

Description

technical field [0001] The invention relates to the technical field of metal material processing, and relates to a hard alloy finishing finger milling cutter and a processing method. Background technique [0002] At present, the production of finger-shaped milling cutters is to use the overall high-speed steel material as the cutting material, which becomes a tool for processing gear teeth after forging and machining; high-speed steel finger-shaped milling cutters can only process materials with a hardness below HB300. When working with uneven modulus and quenched and tempered hardness, the tool wear will be accelerated, and even the processing will not stop, and the tool will be regrinded frequently, so the machining accuracy of the gear is low. Some use carbide finger milling cutters, but basically they are used for roughing. Since the precision of the finished tooth profile is difficult or impossible to guarantee, there is no tool available for the finishing of the gear ...
