Description
Technical field
The invention belongs to optics and manufacture field, be specifically related to a kind of double-flexibility wheel head magnetic rheology buffing device, refer in particular to a kind of for heavy caliber, high precision position phase class optical element being carried out to the double-flexibility wheel head magnetic rheology buffing device of MRF.
Background technology
The continuous phase board of heavy caliber (Continuous Phase Plate, CPP) is a kind of novel position phase class optical element with continuous corrugated high relief topological structure, is mainly used in target surface focal spot shaping and the intensity control of large scale laser instrument.With traditional random order phase-plate (Random Phase Plate, RPP), cease mutually phase board (Kinoform Phase Plate, KPP) and distribution phase plate (Distribution Phase Plate, DPP) equipotential phase class component is compared, CPP has higher capacity usage ratio, more accurate focused spot control characteristic, is considered to realize the most effective solution of large scale laser instrument beam smoothing.It is 430mm * 430mm, strict continuous and face shape error RMS≤30nm, amplitude PV≤10 μ m, the period L≤5mm in corrugated that CPP adopts quartz material, size usually.This " bottom surface shape error, large profile depth and little space periodic " embossment corrugated structure of CPP makes its accurate manufacture extremely difficult, traditional phase part manufacturing technology, the manufacture demand that for example many masks alignment, maskless are directly write, gray-tone mask and etching forming technique all can't meet heavy caliber CPP.
MRF is closely to be able to during the last ten years footpath, a kind of certainty rim of the mouth polishing technology of fast development, it mainly utilizes the controllable rheology characteristic of Magnetorheologicai polishing liquid to be processed, the intensity by controlling magnetic field with distribute control " flexible bistrique " shape with hardness, by the movement locus of control " flexible bistrique " and the material removal that the residence time parameter is controlled ad-hoc location.With traditional polishing technology, compare, Technique of Magnetorheological Finishing has the distinguishing features such as high machining accuracy, high convergence efficiency and nearly free of surface defects, can high efficiency, solve plane, sphere, particularly an aspheric Ultraprecision Machining difficult problem at low cost, being described as is " revolutionary character " technology that optics is manufactured boundary.
Adopt the critical technological point of Technique of Magnetorheological Finishing processing heavy caliber CPP to be mainly manifested in following two aspects: the one, how to remove efficiently the thick optical mirror plane quality that reaches the metamorphic layer of several microns and obtain fast degree of precision that the prefix operation produces on the CPP element; The 2nd, the embossment corrugated how with high fidelity mint-mark goes out to have " bottom surface shape error, large profile depth and little space periodic " feature again on the optical mirror plane obtained.As can be seen here, the magnetorheological processing of heavy caliber CPP has proposed very stern challenge to traditional " single flexible bistrique " MRF equipment, that the removal function form that on the one hand high efficiency processing request equipment generates is wanted is large, efficiency wants high, and the high-fidelity mint-mark but requires to remove that the form of function is little, efficiency is low on the other hand.And traditional " large flexible bistrique " can't obtain and realize the necessary small removal function of CPP high-fidelity mint-mark although the MRF technological equipment can be removed metamorphic layer and most of processing capacity efficiently; And traditional " little flexible bistrique " can't remove metamorphic layer and most of processing capacity rapidly although the MRF technological equipment can obtain small removal function.Therefore, the magnetorheological processing of heavy caliber CPP must be combined the technological ability of " large and small flexible bistrique ".In addition, CPP processing also requires the main movement shaft of MRF technological equipment should have larger speed and acceleration responsive and regulating power.
Known according to pertinent literature and patent, existing magnetorheological finishing device is mainly in order to solve the high accuracy processing problems of plane class or lens class optical element, and single flexible bistrique configuration is the common trait of these devices.The Chinese patent that denomination of invention is " for the magnetorheological finishing device of aperture aspherical optical element " (application number: 200810030898.1) document, the vertical planer-type magnetorheological polishing machine of a kind of six axle of University of Science and Technology for National Defence's exploitation is disclosed, this device has only configured a flexible bistrique of larger specification, the removal function form generated is larger, can't meet the processing request of CPP; The Chinese patent that denomination of invention is " for the magnetorheological finishing device of high-steepness optical part " (application number: 200810031898.3) document, a kind of six shaft vertical structured magneto-rheological polishing machines of University of Science and Technology for National Defence's exploitation are disclosed, this device has only configured the flexible bistrique of a small dimension, does not possess the working ability of optical elements of large caliber.Current domestic two bistrique magnetic rheological polishing methods and the device that can be used for machining position phase class component (for example heavy caliber CPP) that there is no.
