Abstract

The invention discloses a method for machining a hard alloy cutter. The method comprises the steps that blanking is carried out through a grinding wheel or a wire cutting machine according to a drawing size firstly, and the length of materials is reserved for 0.5 mm to 1 mm in the blanking process; the end faces at the two ends of the materials are ground flush, then the end faces ground flush are adopted as a datum, the end faces of the materials are ground flush through a numerical control tool grinding machine, the end faces of the materials continue to be ground off by at least 0.3 mm, the other end of the materials is ground till the reserved size in the step 1 is ground out, and the cutter is machine-shaped according to a design drawing at this moment. Therefore, the strength of a cutter head of the machine-shaped cutter can be effectively guaranteed, especially the strength of an edge of the cutter head, the phenomenon of tipping is prevented from happening to the cutter in the use process, and the service life of the cutter is prolonged.

Description

A kind of hard alloy cutter processing method
Technical field
The present invention relates to a kind of hard alloy cutter processing method, belong to tooling cost field.
Background technology
Carbide alloy is made up through the method for powder metallurgy of refractory carbide (as WC, TiC, TaC, NbC etc.) and metal adhesive (as Co, Ni etc.) powder.Owing to all containing a large amount of metal carbides in carbide alloy, these carbide have the features such as fusing point is high, hardness is high, chemically stable is good, Heat stability is good, and therefore, the hardness of Hardmetal materials, wearability, heat resistance are all very high.Cobalt content in hard alloy substrate directly affects cross-breaking strength (TRS) and the hardness of material, cobalt is binding agent element main in carbide alloy, increase the toughness (TRS) that cobalt content can improve matrix material, but the wearability of material can be reduced because hardness declines simultaneously, otherwise, as reduced cobalt content, the hardness of material and wearability will improve, and toughness then can decline.Bending strength, the fracture toughness of conventional carbide alloy are more much lower than high-speed steel, and the cutting vibration therefore can born and impact load do not have the strong of high-speed steel yet.
In hard alloy cutter process, first need to adopt emery wheel or wire cutting machine to carry out blanking, but when blanking, the high temperature of the generation of wheel grinding material is easy to material end to burn, and equally, can produce electric discharge corrosion during wire cutting machine blanking to material end, material end is made to produce galvano-cautery layer, the burn layer of material end or corrosion layer produce de-cobalt or decarburizing reaction, cause alloy material to go bad, reduce materials'use performance.Because material end normally processes the position of cutter head, therefore the burn layer of material end or corrosion layer will have a strong impact on the intensity of cutter head, and during use, the cutting edge of cutter head easily produces tipping phenomenon, greatly reduces cutter life.
Summary of the invention
The object of the invention is to, a kind of hard alloy cutter processing method is provided, effectively can ensure the intensity at the cutter head position of cutter, improve its service life, to overcome prior art deficiency.
Technical scheme of the present invention: a kind of hard alloy cutter processing method, comprises the following steps:
Step one, first adopt emery wheel or wire cutting machine to carry out blanking according to figure paper size, during blanking, the length of material reserves 0.5 ~ 1mm;
The end face at step 2, abrasive material two ends, then using the end face after polishing as benchmark, numerical control tool grinder removing material end face is adopted to polish again, material cross grinding is continued to fall at least 0.3mm, then the removing material other end, until the reserved size in step one has been ground, now according to design drawing, tool sharpening is shaping; During grinding, the rotating speed of emery wheel is 1500 ~ 2000rpm, and the amount of feeding is 0.001 ~ 0.005mm, and constantly adopts cooling fluid cooling in grinding process;
Step 3, to the process of cutter surface coating.
The emery wheel of described numerical control tool grinder adopts skive, and the grain size number of emery wheel is 60 ~ 80.
Owing to adopting technique scheme, the invention has the advantages that: the present invention adopts numerical control tool grinder the burn layer produced during material end blanking or corrosion layer grinding to be removed, and then carries out tool sharpening is shaping again.Prove after deliberation, the thickness of above-mentioned burn layer or corrosion layer is greatly about 0.3mm, therefore, by the cutter that processing method of the present invention makes, to burn after layer or corrosion layer remove in advance, effectively can ensure the intensity of the intensity, particularly cutter edge of cutting tool insert after machine-shaping, prevent cutter from producing tipping phenomenon in use, improve cutting-tool's used life.
Detailed description of the invention
In order to make the object of the invention, technical scheme and advantage clearly, be 80mm below with processing length, diameter is the carbide-tipped milling cutter of 10mm is example, and the present invention is described in further detail.
Embodiment
The processing method of above-mentioned carbide-tipped milling cutter, can adopt following steps:
Step one, first according to figure paper size adopt wire cutting machine carry out blanking, the length of blanking is 80.5 ~ 81mm;
The end face at step 2, abrasive material two ends, then using the end face after polishing as benchmark, numerical control tool grinder removing material end face is adopted to polish again, material cross grinding is continued to fall at least 0.3mm, then the removing material other end, until material overall length is 80mm, now according to design drawing, tool sharpening is shaping; During grinding, the rotating speed of emery wheel is 1500 ~ 2000rpm, and the amount of feeding is 0.001 ~ 0.005mm, and constantly adopts cooling fluid cooling in grinding process; The emery wheel of described numerical control tool grinder adopts white fused alumina emery wheel, and the grain size number of emery wheel is 60 ~ 80;
Step 3, to the process of cutter surface coating, complete tool sharpening.
