Description
Technical field
The present invention relates to polissoir and polishing technology field, the polissoir of especially a kind of precise thin-wall part and its
Polishing method.
Background technique
In vacuum coating equipment, ion source aperture plate is a kind of important component for generating high energy ion beam, this base part
Work in high voltage, the condition of high temperature.Its surface is not allow for any microcosmic burr, is also not allow for subtle deformation, otherwise can
Cause major accident due to point discharge.
Precision component this for ion source aperture plate can be with by good surface treatment in the final stage of processing
The abrasion for reducing product, improves the satisfaction and an indispensable important step of client, and especially there are also some applications
Metal parts in high temperature high voltage environment can have bright surface quality that can greatly reduce and draw because of point discharge
The sparking failure risen.
Polishing is current increase piece surface finish, reduces the main method of roughness, metal parts is common at present
Polishing method substantially has: (1) important part uses grinding-material and electric tool hand polish；(2) when burr is less
The microcosmic protrusion of material surface is corroded in the electrolytic solution using electric current；(3) part not being not easy to deform strictly is required
It is polished using vibration.
Aperture plate part is during hand polish at present, if due to the deficiency of worker's experience, be easy to cause it is some not
Good consequence, such as: (1) pressure that milling tool is applied to part can be such that part is deformed beyond the critical point of deformation；(2) it grinds
Bistrique pressure at various locations and grinding rate are inconsistent, and piece surface is caused piebald occur；(3) grinding head is in parts locally
Position overstays, and is easy that piece surface is made to cross thermal burn, or cross and cut influence size；(4) grinding head is in part boundary position
Easy bounce causes hand-held shakiness to cause waste product and tool damage to product with severe impact；(5) the fixed batch of hand polish
When product, there is a strong possibility, and property keeps the characteristic of product inconsistent；It (6) is all that part is totally immersed into electrolyte when electrobrightening
In, required electric current is too big, reaches tens amperes of intensity every square centimeter, and it is relatively high to power supply and fixture requirement, accordingly
Equipment investment is required also bigger；(7) it in the position of fixture and feature contacts, is easy to block impact effect because of fixture, also hold
Easily because of the too big generation ablation of contacting points position electric current；(8) precise thin-wall part may be deformed because high current overheats；(9) because leading
Electrical reason, the electrobrightening effect in the pit of product or hole are bad；(10) product surface with conductive plate distance because having far
Close point, causes the electric current of each position in surface inconsistent, easily product surface is made flaw occur.
Therefore, good to obtain in process for aperture plate part or other accurate thin-walled parts
Surface finish then cannot carry out polishing merely by the single process of tradition, and need the surface for part
Characteristic and architectural characteristic carry out specific aim and take polishing scheme.

9. a kind of polissoir of precise thin-wall part according to claim 1, it is characterised in that: the sliding block and guiding
The slide contact part of bar is equipped with sliding sleeve, and the sliding block is slidably connected by sliding sleeve and guide rod.
10. a kind of polishing method of the polissoir of precise thin-wall part, feature according to any of the above-described claim
Be: it includes the following steps:
(1) polished part is clamped in the tooling for being used for holding parts of mechanical polishing mechanism, then starting is slowed down electric
Machine rotates the shaft of decelerating motor with the speed of 60~600r/min with movable eccentric wheel, enables the connecting rod on eccentric wheel
It is drivingly connected block and then does linear reciprocating motion along guide rod with movable slider, make the polishing cloth of sliding block lower end surface to for clamping
Polished part in the tooling of part is polished, and it is primary so that the surface of polished part is at least polished emery cloth polishes；
(2) part after the polishing of mechanical polishing mechanism is placed in electrobrightening mechanism to the tooling for being used for retaining element,
The electrolyte mixed using phosphoric acid and sulfuric acid as main component is extracted with acid-proof pump, first passes through quartz ampoule to electrolyte
It is heated, wherein the heating temperature of quartz ampoule is 50~200 DEG C, will keep certain temperature by acid metal jet pipe later
Electrolyte is sprayed on polished part, and wherein part connects positive pole, and acid metal jet pipe connects power cathode, in acidproof gold
Belong to the voltage for keeping 9~24V between jet pipe and part, makes from conductive between the electrolyte and part that acid metal jet pipe comes out；
Acid metal jet pipe is mounted on numerical control triaxial slide unit, makes acid metal jet pipe confronting parts according to predetermined by host computer programming
Track it is mobile, therefore the electrolyte of electrification that comes out of acid metal jet pipe according to setting track equably with feature contacts,
To realize the oxide skin for uniformly removing subtle burr and surface with minimum electric current；
(3) part after electrobrightening is fixed on the slide unit of numerical control polishing mechanism, then in numerical control polishing mechanism
It is carried out on host computer with numerical control program control grinding head according to corresponding track on piece surface with the speed of 0.5~3m/min
It is mobile, while sprinkling has added the suspension of grounds travel between grinding head and part, reaches polishing purpose, in addition, by revolving
Turn pressure signal transmission that the pressure sensor between main shaft and main shaft fixture will test to host computer, so that real-time control is revolved
Turn the main shaft pressure value finely tuning and grinding head pressure is made to be maintained at setting up and down, go on smoothly polishing can, and will not allow zero
Part deformation, wherein the revolving speed of main shaft is 1000~10000r/min.
