Relate to a kind of new burnishing device, belong to the polishing manufacture field.
Background technology
It is a kind of novel polishing process technology of utilizing the electric rheological effect of ER fluid to polish that electric current becomes polishing.ER fluid is a kind of suspension, and it is made up of the decentralized photo and the good continuous phase of insulating properties of big dielectric constant.Under electric field action, it is big that the viscosity of ER fluid becomes, and type of becoming solid has tangible anti-shearing surrender ability, and this phenomenon is called electric rheological effect.
The principle that electric current becomes polishing is to sneak into abrasive material in the ER fluid, and under electric field action, can condense is the rubbing head of a flexibility, uses this flexible polishing head that workpiece is polished, and rubbing head hardness is relevant with the electric-field intensity at contact point place.
In general, for specific polishing tool, it removes model is changeless, in order to obtain higher surface quality, needs to carry out trajectory planning according to the curved surface information of removing model and polish.In this technology path, most critical, the most complicated work is exactly trajectory planning.Because at the clearance skewness of polish, so surface of the work is removed irregularly behind the stock removal polishing, has than mistake during the polishing of conventional polishing tool.Solution commonly used is repeatedly to polish repeatedly, relies on probability to obtain more excellent face shape and surface quality.But this method causes polishing time long, and weak effect is difficult to obtain the superhigh precision surface.The main path that improves the polishing precision at present is the research to polishing locus planning, but because the limitation on the principle is difficult to obtain controlled high-precision surface quality.
Electric current becomes the employed rubbing head of polishing technology and is made up of intellectual material-ER fluid.The hardness of rubbing head can be through changing electric-field intensity control, and the change voltage method is convenient regulates and electric-field intensity can be passed through.Owing to this character of ER fluid, can in polishing process, initiatively change the Electric Field Distribution of polish, make rubbing head in polish, have uniform removal model.Based on this thought, the electric current of having invented a kind of contrary structure electrode becomes the uniform polish device.
