Description
Technical field
The utility model is related to field of machining, more particularly to a kind of imitating milling cutter Sharpening device.
Background technology
Milling cutter belongs to processing consumption product, and the processing of mechanical processing industry spare and accessory parts has 30% work to be completed by milling.Due to milling
Knife complex geometry brings great difficulty to milling cutter edge grinding, it is therefore desirable to its blade is sharpened after its abrasion, increases its cutting edge of a knife or a sword
Sharp degree is so that it can put back into, and so as to improve the entire life of cutter, reduces processing cost.
And milling cutter generates the main reason for wearing and includes：(1) wear and tear in machines：By chip and cutter rake face, work pieces process
Abrasion caused by severe friction after the flexible deformation and cutter of appearance between knife face, is known as wear and tear in machines.In cutting temperature
When less high, the machine scratch as caused by this friction be tool wear important because.(2) thermal wear：During cutting, due to gold
Cutting heat caused by the severe plastic deformation of category and friction makes the hardness of blade low and loses toward the mill caused by cutting ability
Damage is known as thermal wear.In addition to above two is worn, separately there are following several abrasions：(3) under high temperature and pressure, cutter and workpiece matter
It is present with cohesive presentation between material, and has a local tool material to be taken away by chip, cutter is made to generate bonding abrasion；(4) in higher
At a temperature of, some elements (such as tungsten, cobalt, titanium) that cutter matter is guessed right will be spread into workpiece material, so that Tool in Cutting
The chemical factor variation on local surface layer, also low tool strength and wearability make cutter generate diffusive wear；(5) height is tackled
Fast steel cutter, under higher cutting temperature, the metallographic construction of tool surface can generate variation, make hardness and wearability low,
Phase transition wear will be present with.Each cutter tooth of milling cutter be it is periodic stop cutting, cutter tooth by idle running to being cut, temperature
Amplitude of variation it is very big, it may be said that every time cut all be subject to once heat strike.Hard alloy cutter, in heat into forcibly occupying, knife
Very big stress can be generated inside piece, and causes cracking, cutter hot tearing is caused to wear.
But since milling cutter is cut with being off, so that cutting temperature is high unlike turning, therefore cutter is caused to grind
The major reason of damage is wear and tear in machines caused by machine friction usually.
Just existing sharpening milling cutter technology at present, after old cutter wear, generally by knife sharpener or hand grinding milling cutter
Side edge outer circle increases its sharpness.Either craft or machine inevitably changes the outer circle geometry of milling cutter, ruler
Very little to become smaller, circularity is lower.In addition, this method also has many drawbacks：(1) cutter material, milling cutter surface are the hard layer of cutter,
The hardness of cutter is assigned, it is more softer to the material of inner layer cutter, therefore the hardness of cutter constantly declines, and can not meet machining
Primary condition.(2) tooling allowance, by the milling cutter side edge of sharpening, not only diameter tolerance is uncontrollable, but also the concentricity of cutter
It can not ensure, be easy to cause processed cut or quality is bad, it is difficult to ensure normal process requirements.
Processing will not only consider the precision of cutter, the hardness of cutter and cutting wear, but also consider that cutter is assigned
The efficiency of processing is given, sharpening milling cutter side edge cannot not only reduce processing cost, but also reduce processing efficiency, reduce processing essence
Degree, while the basic principle of processing has also been run counter to, it is a kind of cacodoxy to lose more than gain.
