Technical field
The present invention relates to a kind of polishing system of processing based on flexible controllable pressure emery wheel, relating in particular to the auxiliary polishing technology of a kind of and robot combines, be applicable to the polishing of high-quality surface requirement free form surface, especially to having the surface of high rigidity, high-wearing feature behind the laser reinforcing, good crudy of tool and efficient.
Background technology
Polishing processing is meant after fine finishining, does not excise or cut out metal level as thin as a wafer from workpiece to be processed, and in order to improve workpiece surface roughness or to strengthen its surperficial process, the method that adopts comprises polishing and grinds usually.Because the application of free form surface in industry is increasingly extensive, and constantly variation, complicated, make the difficulty of polishing processing also increase thereupon.
China mainly relies on its rich experiences to finish polishing by the experienced operator at present, this is not only very high to workman's specification requirement, not only time-consuming but also require great effort, and the difficult quality guarantee on surface, efficient is very low, especially hardness is higher, the surface of high-wearing feature at having behind the laser reinforcing, and its drawback is particularly outstanding.Except that artificial polishing, traditional finishing method generally is to utilize spring or flexible polishing material to obtain instrument to contact with flexibility between the burnishing surface, thereby reaches the purpose of polishing.Grinding then is to remove small allowance by the mobile generation mechanical friction and the chemical action of abrasive material between workpiece and hard lap tool or lapping liquid.Therefore, adopt polishing to carry out polishing processing and can effectively be applied to free form surface, obtain smooth surface and bright luster effect, and utilize the flexible polishing instrument often can not obtain desirable polishing efficiency as manufacturing process, material removing rate is lower.Grind then and can carry out polishing processing to difficult finished surfaces such as high rigidity, high-wearing features effectively, but traditional milling tool is relatively poor to the adaptability of curved surface, not high with the profiling degree of work surface, on using, be very restricted.
Summary of the invention
The efficient that exists in the existing polishing process technology is low, controllability is not high in order to overcome, the shortcoming of the deficiency of poor practicability, automation, the invention provides the auxiliary polishing technology of a kind of and robot and combine, have efficient height, self adaptation is good, technology is simple, controllability is strong polishing system of processing based on flexible controllable pressure emery wheel.
