Description
Technical field
The present invention relates to a kind ofly, especially relate to a kind of cup type grinding wheel trimming device with angle with online measuring ability to the aspherical mirror machining emery wheel.
Background technology
At present, skive is adopted in the grinding of optical material usually.Be used for the difference of the aspheric skive of grinding, can be divided into: four kinds on flat-faced wheel, inclined-plane (round platform) emery wheel, arc diamond wheel and spherical emery wheel according to its peripheral cross-section shape.Grinding not only requires grinding accuracy, and requires grinding efficiency simultaneously, and emery wheel is as the critical component of grinding, and except the structure of itself, the correction method of its finished surface also is the key factor that influences the wheel grinding performance.The purpose of correction of the flank shape is to eliminate the form error and the blemish of emery wheel, makes emery wheel have geometrical precision accurately, in order to avoid produce vibration in grinding, causes uneven unequal cutting.Therefore to any grinding machine, the height of the quality of grinding wheel dressing directly affects the machining accuracy of part, and it is a key technology in the precision grinding machining.Nowadays, the accurate correction of the flank shape technology of superhard ultra micron skive has obtained the technology expert's of various countries great attention, and has developed and multiple practical approach.
In order to reach the requirement on machining accuracy of high accuracy aspherical lens, the profiling mode of selection skive will directly have influence on the machining accuracy and the surface quality of workpiece.Table 1 has been enumerated the profiling mode of several skives commonly used.Indexs such as the form accuracy that various profiling modes can reach in the contrast table 1, surface roughness and correction of the flank shape efficient can obtain for the skive with high-precision requirement.
The profiling mode of table 1 skive relatively
| The correction of the flank shape type | The workpiece form accuracy | The workpiece roughness value | State of the abrasive grain | Correction of the flank shape efficient |
| Single-crystal diamond | High | Greatly | Fragmentation is many | High |
| The rotation diamond wheel | In | In | In the fragmentation | High |
| The comprehensive shaping | In | Little | Good | Low |
| The electric spark correction of the flank shape | In | In | In the fragmentation | In |
| ECD electrochemistry | High | Greatly | Good | High |
| The discharge correction of the flank shape | In | Little | Good | In |
| The cup-shaped emery wheel | High | Little | Good | Low |
| The laser correction of the flank shape | High | In | Good | In |
The laser correction of the flank shape is as a kind of noncontact correction of the flank shape method, the effect of avoiding power with contact firmly, fusing and gasification mechanism based on heat, be undoubtedly rising correction of the flank shape technology, but need further carry out multi-faceted research in a deep going way, when adopting laser correction of the flank shape super-abrasive grinding wheel simultaneously, also exist many problems.If the laser dressing parameter is improper, bond and abrasive material will be removed simultaneously, wheel face is destroyed because of zanjon occurring, and the carbonization phenomenon of the influence of Stimulated Light spot diameter and diamond abrasive, the dressing of laser correction method incompatibility fine-granularity diamond emery wheel.With present technology maturation degree, the employing cup type grinding wheel trimming device carries out correction of the flank shape, dressing is more satisfactory working method, its combination property the best is (referring to document: Y.Keunieda, H.Matsuura, S.Kodama, N.Yoshihara, J.Yan, T.Kuriyagawa.Development of New LaserConditioning Method for Micro Aspherical Grinding, Proceeding of Conference on Jspe.2006,499).
The correction of the flank shape mechanism of cup-shaped grinding wheel dressing method is as follows: in the correction of the flank shape process, the abrasive particle that splits away off from the cup-shaped emery wheel produces the correction of the flank shape effect to the impact and the abrasive action of diamond abrasive grain and bond.The abrasive particle that splits away off is big more, and correction of the flank shape efficient is high more, and diamond surface is coarse more.Owing to rely on from the come off abrasive action of abrasive material and skive of cup-shaped emery wheel, during therefore to the correction of the flank shape of compact-type skive, get final product shaping, also dressing simultaneously, but the consume of correction of the flank shape instrument is seriously.Because the resistance during shaping is very little, therefore can obtain higher plastic precision.Adopt cup type grinding wheel trimming device correction of the flank shape super hard abrasive formed grinding wheel, its correction of the flank shape efficient and correction of the flank shape precision all than traditional formed grinding wheel correction method height (referring to document: 1, W.Ling, H.Omori, T.Yamada, et al.Studies on manufacture of long dimension X radial mirror[C] .Proceedings of Jspe, 2000, (10): 296; 2, village department gram is male, Zhou Libo, Tang Jianshe. the shaping of super-abrasive grinding wheel and dressing, manufacturing technology and lathe [J], 1993 (5): 14-18).But the correction of the flank shape mechanism of cup-shaped emery wheel mainly depends on grind etching off the remove effect of abrasive material to bond, so just cause the loss of dresser bigger, need with complicated special-purpose correction of the flank shape device, be difficult to realize the online correction of the flank shape of emery wheel simultaneously, these effects limit its scope of application in precision and superfine grinding.
