Description
Technical field
The present invention relates to precise machine machining field, particularly relate to a kind of adamantine grinding and polishing method.
Background technology
Diamond is with the physical and mechanical properties of its uniqueness, and especially its high hardness, has in industry manufacture and scientific and technical research field the application being difficult to substitute.The U.S. in the 50's Mos of eighties of last century, for the demand for development adapting to ultra precision cutting technology develops SPDT(Single Point Diamond Turning) technology.In this technology, diamond is as cutting tool manufactured materials, and this also makes diamond cutter manufacturing technology become key technology in ultraprecise field of machining.Diamond itself has strong anisotropy.Most typical in the present frictional behavior of this property list is exactly that the material removal efficiency in the different crystal face crystal orientation of diamond presents significant difference under same mechanical lapping condition.In reality when to adamantine some crystal face attrition process, in order to raise the efficiency, always will adjustment gradually, the grinding direction finding material removing rate high, and the parameter values in concrete sign grinding direction is difficult to obtain.
Given this, Chinese patent literature CN 103616394 A discloses a kind of method determining diamond lap crystal orientation, by providing an abradant surface and the rib needing attrition process surface to be formed as the way with reference to crystal orientation in advance, only need to do initial demarcation to crystal face crystal orientation, laser confocal microscope just can be adopted in follow-up attrition process to measure the characterization parameter in concrete grinding direction, do not need the locus and the attitude that record the placement of diamond workpiece, convenient and swift.But, before grinding and polishing is carried out to diamond, first to determine this step in diamond lap crystal orientation, inherently greatly reduce diamond grinding polishing operating efficiency.Therefore, be necessary to design a kind of novel polished machine and adamantine grinding and polishing method to overcome above-mentioned defect of the prior art, accomplish real effective raising operating efficiency.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of adamantine grinding and polishing method that can increase substantially efficiency.
To achieve these goals, the adamantine grinding and polishing method of one of the present invention, while mill High Rotation Speed carries out grinding and polishing to diamond particle surfaces, drive the clamping device of clamping diamond particles with the vertical line in described mill grinding and polishing face for axis rotates by drive unit.
When carrying out grinding and polishing to diamond particles, the spring mechanism being positioned at clamping device is used to be withstood on the grinding and polishing face of mill by described diamond particles.
The multiple diamond particles of described gripping apparatus grips, described drive unit drives multiple clamping device to rotate by planetary gear mechanism simultaneously.
Adopt technique scheme, adamantine grinding and polishing method of the present invention, after changing the grinding crystal orientation first determining diamond particles in traditional grinding and polishing method, again single or two diamond particles are fixed and ground by the direction of mill according to this crystal orientation simultaneously, and on mill, move reciprocatingly the method guaranteeing diamond disk surface opposed flattened, but in grinding and polishing process, make the vertical line of many diamond particles around mill grinding and polishing face carry out 360 ° of rotations, thus mill can grind in each crystal orientation of diamond particles, eliminate in prior art the step needing to determine diamond particles grinding crystal orientation on the one hand, effectively improve operating efficiency, mill can be kept evenly to consume on the other hand, thus without the need to finishing, extend the service life of instrument.
