Description
Present patent application is that invention and created name is " medical titanium alloy small piece ultrasonic-magnetorheological compound finishing
The divisional application of the patent of invention of machine ", applying date of original application is September in 2013 28 days, the Application No. of original application
2013104674564。
Technical field
The present invention relates to a kind of milling tools, specially a kind of medical titanium alloy small piece ultrasonic-magnetorheological compound finishing
Machine.
Background technology
Conventional glossing has at present：Electrochemical polish, electrobrightening, ultrasonic polishing etc., can effectively solve the problem that titanium
The problem of polishing of alloy workpiece surface is difficult, but they each have insoluble technical disadvantages and deficiency.Electrochemical polish
Do not limited with electrobrightening by workpiece material hardness and toughness, but be difficult to obtain higher machining accuracy, and it is spuious during processing
Corrosion phenomenon is more serious.Ultrasonic polishing is adapted to the various hard brittle materials of polishing, and quality of finish is high, and surface roughness is up to Ra
0.63~0.08 μm, but ultrasonic polishing is only used for processing non-conducting material, and limited by ultrasonic amplitude and power, surpass
Sound wave polishing is only suitable to the partial operations such as narrow slot fillet, corner angle, and the polishing efficiency of large area is relatively low.
Magnetic flow liquid be by the magnetic-particle of micron-scale be scattered in insulation carrier fluid in formed have controllable rheology behavior
Suspension liquid, its rheological behavior with externally-applied magnetic field change and change.Magnetic flow liquid rheological behavior not plus during magnetic field with it is common
Newtonian fluid is similar, and when by some strength magnetic fields, obvious magnetic rheology effect can be produced under the influence of a magnetic field, its
Apparent viscosity coefficient increases more than two orders of magnitude, can become the state of similar " solid ", once removing behind magnetic field, becoming again can
With the liquid of flowing.Magnetic rheology effect under magnetic fields, makes magnetic rheological liquid be changed between liquid and solid-state, tool
There is reversible, controllable, willing advantage.The shear yield stress of magnetic flow liquid is more order of magnitude greater than ER fluid, and
Magnetic flow liquid has good dynamics and temperature stability, therefore, compared with ER fluid, the wider model of application.
Magnetic converting technique is applied to optical manufacturing by Kordonski of Byelorussia in 1992 et al. earliest.Nineteen ninety-five is beautiful
Optics manufacturing center of Rochester University of state cooperates with Kordonski, and Technique of Magnetorheological Finishing is applied in optical manufacturing, made
Fused quartz aspherical elements surface roughness is reduced to 0.8nm (RMS), 0.09 μm of face shape error, BK7 aspherical optical elements surface
Roughness is reduced to 0.86 μm of 1nm (RMS) face shape error.Kordonsk et al. is also by Jet Polishing technology and MRF skill
Art is combined, and has invented a kind of new polishing method, and magnetorheological Jet Polishing, this processing mode can effectively solve deep concave surface
Or the polishing of inner chamber.
China is also studied Technique of Magnetorheological Finishing in recent years, the unit pair such as Changchun optical precision optical machinery research institute
MRF theory is inquired into, and have developed MRF equipment, while they also go out with Fudan University's cooperation research and development
Oil base magnetic flow liquid, has carried out MRF experiment.Harbin Institute of Technology, which have developed, is suitable for the water base of MRF
Magnetic flow liquid, on homemade MRF experimental prototype, polishing has been carried out to materials such as optical glass, devitrified glasses real
Test, the Primary Study influence of each burnishing parameters have studied polishing removal behavior and Surface contral technology.Tsing-Hua University, national defence
University of Science and Technology have developed MRF equipment.But these all rest on the experimental study stage, not yet obtain practical application.
The research of the current polishing processes to titanium alloy, Xibei Inst. of Non-Ferrous Metals autonomous Design develops a kind of new
Biomedical β-type Ti alloys, and the electrochemical polish of bio-medical TLM titanium alloy capillaries is studied.Beijing Aviation space flight
The university research environmentally friendly electrochemical polishing process of titanium alloy.University Of Dalian draws during electrobrightening titanium alloy implant
Enter power ultrasonic, review and analyse effect of the power ultrasonic to electrobrightening process and the influence to polishing effect.With
These upper titanium alloy polishing processes are not applied also on a large scale at present also in theoretical research stage in production practices.
Although there is some to can be used for the conventional polishing process of medical titanium alloy (such as bone plate and bone screw) at present,
Desired processing effect is extremely difficult to, and it is less efficient.On the one hand because the size of polishing area is smaller, this requires polishing
Instrument is also sized to corresponding reduction, and the manufacture of miniature polishing tool has certain difficulty, and polishing area is limited in into very little
In the range of technically there is also difficulty；On the other hand, free abrasive as much as possible is gathered in for a long time as far as possible
Machining area to improve polishing efficiency be it is extremely important, it is smaller yet with polishing area, free abrasive be difficult to high-density,
Concentration of local is in polishing tool and aspherical smaller contact area for a long time, therefore is extremely difficult to expected Polishing machining effect
Really.In addition, the abrasion of instrument in polishing must also be overcome, polishing tool and the pasting property or compliance in aspherical region are improved,
To obtain high-quality polished surface.
The high-precision requirement of medical titanium alloy micro parts is met, and makes every effort to improve polishing efficiency on this basis
Compliance, just must find the method for processing titanium alloy using new principle while traditional precision machining method is improved.
