Abstract
The invention discloses a kind of cutting edge roundness magnetic powder passivation technologies, first on a robotic arm by cutter holding, it is rotated by manipulator main shaft band cutter, then it is placed between rotatable brush by manipulator clamping cutter, magnetic powder is had in the brush, magnetic powder forms abrasive grain brush under the influence of a magnetic field, is passivated by abrasive grain brush to cutting edge roundness.The present invention not only improves cutting edge roundness quality using magnetic powder passivation, improve machined surface quality and cutter life, and cutting edge roundness passivation efficiency is also improved, cutting edge passivation effect is significantly improved, to achieve the purpose that cutting edge roundness is efficient, high-quality passivation.
Description
Technical field
The present invention relates to a kind of cutting edge roundness magnetic powder passivation technologies, belong to cutter manufacture technical field.
Background technique
After grinding, often there is microdefect on surface in cutting edge with cutter, such as flash, sawtooth, micro- notch, residual
Residue stress and the leaching of edge surface cobalt etc., this slight imperfections can cause cutting process unstable, influence machined surface quality, drop
Low cutter life.It not only can change tool in cutting sword geometry by passivation technology, improve cutting edge microscopic appearance,
But also the finish of cutting edge can be improved, thus reach improve cutter cutting stability, increase the reliability of cutter with
And improve the purpose of the surface quality of work piece.However not only the time is long, low efficiency for existing common passivation technology, but also sword
Mouthful finish is poor, effect is not significant, especially the cutter of difficult-to-machine material, not only needs cutting edge finishing good, but also need to be compared with
Big cutting edge radius of corner, common passivation are then difficult to be satisfied with requirement.
Summary of the invention
The purpose of the present invention is to provide a kind of cutting edge roundness magnetic powder passivation technology, which can not only improve tool blade
Mouth quality, improves machined surface quality and cutter life, but also cutting edge roundness passivation efficiency can be improved, significantly changes
Kind cutting edge passivation effect.
To achieve the above object, the invention provides the following technical scheme: a kind of cutting edge roundness magnetic powder passivation technology, first will
Cutter holding on a robotic arm, is rotated, being then placed in by manipulator clamping cutter can revolve by manipulator main shaft band cutter
Between the brush turned, magnetic powder is had in the brush, magnetic powder forms abrasive grain brush under the influence of a magnetic field, by abrasive grain brush to knife
Tool cutting edge is passivated.
In the above method, when passivation, the operating distance of brush is set as 2~4mm, is passivated 8~12 seconds, can be completed blunt
Change.There is a reference position inside machine for inactivating, the distance of brush deviation reference position is the operating distance of brush when passivation.
In the above method, cutting edge radius of corner value is not more than 12 μm after the cutting tool dulling.
In the above method, cutter cutting edge before passivation is regular, consistency is good, without obvious notch and sawtooth, and cutting edge
Radius of corner value is not more than 4 μm.
Compared with prior art, the beneficial effects of the present invention are: the present invention not only improves tool blade using magnetic powder passivation
Mouth quality, improves machined surface quality and cutter life, and also improve cutting edge roundness passivation efficiency, significantly changes
Cutting edge passivation effect has been apt to it, to achieve the purpose that cutting edge roundness is efficient, high-quality passivation.
Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, below with reference to embodiment to the present invention make into
The detailed description of one step.
A kind of cutting edge roundness magnetic powder passivation technology of the invention, this method first by cutter holding on a robotic arm, pass through
Manipulator main shaft band cutter rotates, and is then placed between rotatable brush by manipulator clamping cutter, the brush
Upper to have magnetic powder, magnetic powder forms abrasive grain brush under the influence of a magnetic field, is passivated by abrasive grain brush to cutting edge roundness.When passivation,
The operating distance of brush is set as 2~4mm, is passivated 8~12 seconds, passivation can be completed.Cutting edge fillet half after the cutting tool dulling
Diameter value is not more than 12 μm.Cutter cutting edge before passivation is regular, consistency is good, without obvious notch and sawtooth, and cutting edge fillet
Radius value is not more than 4 μm.
Embodiment 1
The present embodiment by sword diameter for 8mm, for the slotting cutter of machining titanium alloy for illustrate.Cutting edge roundness rule before being passivated
Whole, without obvious notch and sawtooth, cutting edge radius of corner is 1.6 μm, first on a robotic arm by cutter holding, then passes through machinery
Hand clamping cutter is placed between rotatable brush, magnetic powder is had in the brush, magnetic powder forms mill under the influence of a magnetic field
Grain brush, is passivated cutting edge roundness by abrasive grain brush.When passivation, the operating distance of brush is set as 3mm, is passivated 8 seconds, passivation
Cutting edge roundness finishing afterwards, cutting edge radius of corner are 8 μm, and the slotting cutter of cutting titanium alloy is passivated using above-mentioned technique, is not only passivated
It is high-efficient, and it is good to be passivated cutting edge quality.
Embodiment 2
The present embodiment illustrates for the slotting cutter by sword diameter for 12mm, for processing high temperature alloy.Cutting edge roundness before being passivated
Regular, without obvious notch and sawtooth, cutting edge radius of corner is 1.6 μm, first on a robotic arm by cutter holding, then passes through machine
Tool hand clamping cutter is placed between rotatable brush, magnetic powder is had in the brush, magnetic powder is formed under the influence of a magnetic field
Abrasive grain brush is passivated cutting edge roundness by abrasive grain brush.When passivation, the operating distance of brush is set as 3mm, is passivated 12 seconds,
Cutting edge roundness finishing after passivation, cutting edge radius of corner are 10 μm, the slotting cutter of cutting high temperature alloy are passivated using above-mentioned technique, no
Only passivation efficiency is high, and it is good to be passivated cutting edge quality.
