Abstract
The utility model discloses a ring slot formed cutter for nickel-base superalloy manufacture, which comprises blades (1 and 2), a cuter seat (3), a cutter body (4) and a cutter handle (5), wherein a chip breaker groove (6) is arranged on a front cutter surface of each blade, the cutter body is provided with the chip breaker groove, the material matrix of each blade of the cutter is Y126 hard alloy coated with cubic boron nitride (CBN), the outer toothed cutting edge inclination of each blade is minus 3 degrees, and the inner toothed cutting edge inclination of each blade is 3 degrees. As the blades are made of the material, the hardness and durability of the blades is improved, especially the fatigue strength is improved; due to the arrangement of the angles, the blades are sharp, the strength of the cutting edges is guaranteed and the heat radiation condition is improved.
Description
Technical field
The present invention relates to a kind of machining of hard-cutting material, relate in particular to a kind of annular groove milling cutter that is applicable to nickel base superalloy processing.
Background technology
In prior art; Draw ratio is being added man-hour greater than 10 cannelure; Just under the situation to the processing of the cannelure of some big L/D ratios,, add the man-hour cutter and be in the semi-closed state cutting because cutter is enclosed in the part cannelure; Machining condition is abominable, heat in metal cutting is difficult for passing diffusing, smear metal eliminating difficulty, cutter cracky.Especially for some hard-cutting materials; For example nickel base superalloy carries out under the situation of machining, because cutting force is big, material thermal conductivity is poor, the work hardening tendency is big; Be prone to produce serious boundary wear; Be the machining of typical hard-cutting material, adopt existing process tool, be difficult to guarantee crudy and efficient especially these hard-cutting materials to cannelure processing such as the hard-cutting material of nickel base superalloy.
Summary of the invention
These problems to prior art; The goal of the invention of the utility model is to provide a kind of cannelure milling cutter that is applicable to nickel base superalloy processing; Thereby can realize that in to the process of material cutter life is long, guarantee that cutter is sharp and improve radiating condition.
The utility model provides a kind of annular groove profile milling cutter that is applicable to nickel base superalloy processing; Said milling cutter comprises blade, tool rest, cutter hub and tool shank, and said milling cutter is provided with chip-breaker at the rake face of said blade, and said cutter hub is provided with chip pocket; It is characterized in that; The material matrix of the said blade of said milling cutter is coated cubic boron nitride (CBN) for the Y126 carbide alloy adds, the external tooth cutting edge inclination of said blade is-3 °, and the internal tooth cutting edge inclination is 3 °.
Blade adopts above-mentioned material can improve hardness and the wearability of blade and its toughness that do not reduce has particularly improved fatigue strength; The external tooth cutting edge inclination of blade and the setting of internal tooth cutting edge inclination guarantee that cutter is sharp, guarantee cutting edge strength again and improve radiating condition.
The normal relief angle of the blade of milling cutter is 7 °, so setting can strengthen blade cutting edge intensity, improve radiating condition, avoid producing in the process tipping.
The chip pocket of the cutter hub of milling cutter is 15 ° of king bolt flute profile formulas.
The blade of milling cutter adopts the clip type structure, adopts screw that blade is fixed on the tool rest, with screw tool rest and blade assembly is installed on the cutter hub again.

Fig. 3 is the milling cutter body structural representation;
Fig. 4 is the enlarged diagram of I portion among Fig. 3;
Fig. 5 is a milling cutter tool work sketch map.
The specific embodiment
Shown in Fig. 1-4; Milling cutter comprises roughing blade 1, fine finishining blade 2, tool rest 3, cutter hub 4 and tool shank 5, and wherein the blade of milling cutter adopts the clip type structure, also can adopt other structures certainly; Adopt screw that roughing blade 1 or fine finishining blade 2 are fixed on the tool rest 3; With screw tool rest 3 and blade are installed on the cutter hub 4, as illustrated in fig. 1 and 2, cutting plate for milling cutters can be divided into slightly, two types of fine finishining again.Tool shank 5 can be according to using lathe to require to be designed to interior two kinds of forms of cold-peace external cooling.
For adapting to the cut requirement of nickel base superalloy, designed special blade material, material matrix is coated with cubic boron nitride (CBN) for the Y126 carbide alloy adds, and wherein the Y126 carbide alloy is a known materials, and its composition is a Ti content: 3%; Tantalum content 8%; Cobalt content 12%; All the other are tungsten carbide.Thereby improved hardness and the wearability of blade and its toughness that do not reduce has particularly improved fatigue strength, and cube boron nitride coating have very high hardness and young modulus; Good thermal conductivity; Very little thermal coefficient of expansion, less density, lower fracture toughness and good chemistry and heat endurance; More preferably, can be in matrix material the corresponding content that has increased TaC (ramet) and cobalt.
Some hard-cutting materials are being added man-hour; Under the situation of for example processing for nickel base superalloy,, alleviate work hardening in order to adapt to the cut requirement of this type material; Both guaranteed that cutter was sharp; Guarantee cutting edge strength again and improve radiating condition that external tooth cutting edge inclination λ is set is-3 °, internal tooth cutting edge inclination λ is 3 °; Simultaneously for the intensity that strengthens blade cutting edge, improve radiating condition, avoid producing in the process tipping, the cutting edge normal relief angle is set at 7 °; Further for the ease of chip removal, guarantee normally cutting, 15 ° of king bolt flute profile formulas that the cutter hub chip pocket is made.
In treating the process that processing parts 7 processes; At first roughing blade 1, tool rest 3 are installed to and carry out roughing on the cutter hub 4; Unload roughing blade 1 and tool rest 3 then, change fine finishining blade 2, tool rest 3 carries out fine finishining, add and to carry out the inner-cooled cutting according to the situation of using lathe man-hour and also can use the external-cooling type cutting way; Because the blade rake face is provided with chip-breaker 6, guaranteed that smear metal is with the smooth and easy discharge of spiral chip flute along 15 ° of the state of C shape bits.
