Kubvisa Microburrs kubva Diki-Diameter Threads | Brush Research Mfg.

Kana iwe ukaverenga maforamu epamhepo unoziva kuti pane gakava rakawanda pamusoro pekuzivisa iyo yakanakisa nzira yekubvisa iyo isingadzivisike maburrs akagadzirwa panguva yekugadzira yezvikamu zvakarukwa. Shinda dzemukati – angave akachekwa, akakunguruswa kana kuti akatonhora – kazhinji ane maburi pamaburi ekupinda nekubuda napo, pashinda dzeshinda, uye pamakona mazhinji. Tambo dzekunze pamabhaudhi, sikuruu, uye zvirukwa zvine nyaya dzakafanana – kunyanya panotangira shinda.

Kune zvikamu zvakakura zvakasungwa, maburrs anogona kubviswa nekutsvaga zvakare nzira yekucheka, asi izvi zvinowedzera nguva yekutenderera kwechikamu chimwe nechimwe. Kushanda kwechipiri, senge inorema naironi yekubvisa maturusi kana butterfly mabhurashi zvakare anogona kushandiswa.cnc machining chikamu

Zvisineyi, matambudziko anowedzera zvakanyanya kana dhayamita yechikamu chakasungwa kana maburi akachekwa akayera isingasviki 0.125 mukati. Muzviitiko izvi, ma microburrs achiri kugadzirwa asi ari madiki zvekuti kubviswa inyaya yekupukuta pane hutsinye deburring.

Panguva ino, mudiki diki, sarudzo yekubvisa zvigadziriso inoderera zvakanyanya. Maitiro ekupedzisa misa anogona kushandiswa, sekudonha, electrochemical polishing uye thermal deburring, asi izvi zvinoda kuti zvikamu zvitumirwe kunze nekuwedzera mutengo uye kurasikirwa kwenguva.

Kune akawanda mashopu emuchina zviri nani kuchengetedza sekondari mashandiro mukati-mumba, kusanganisira kubvisa, kungave nekutora otomatiki uchishandisa CNC muchina, kana kushandisa madhiri nemaoko, kana hunyanzvi hwemaoko.chikamu chepurasitiki

Panyaya idzi pane mabhurashi madiki ayo — zvisinei nedzinde diki, filaments uye mativi ese - anogona kutenderedzwa pachishandiswa zvibooreso zvemaoko uye kunyange kushandisa maadapter pamidziyo yeCNC. Iye zvino inowanikwa neabrasive nylon, carbon steel, simbi isina tsvina uye diamond-abrasive filaments, zvishandiso izvi zvinowanikwa zviduku se 0.014 mukati, zvichienderana nemhando yefilament.

Tichifunga mukana wekuti maburrs akanganisa chimiro, kukwana kana kushanda kwechigadzirwa, matanda akakwira kune zvigadzirwa zvine tambo diki, zvinosanganisira zvikamu zvewachi, magirazi emaziso, nharembozha, makamera edhijitari, mabhodhi edunhu akadhindwa, midziyo yekurapa chaiyo, uye. Zvikamu zvemuchadenga. Njodzi dzinosanganisira kusarongeka kwezvikamu zvakabatanidzwa, kuomerwa mukuungana, maburrs anogona kusununguka uye kusvibisa hutsanana masisitimu, uye kunyange kumhanyisa kutadza mumunda.

Misa yekupedzisa matekiniki — Misa yekupedzisa matekiniki akadai sekudonha, kupisa kwemafuta uye electrochemical polishing inogona kushanda pakubvisa mamwe maburrs emwenje pazvikamu zvidiki. Kudonha, semuenzaniso, kunogona kushandiswa kubvisa mamwe maburrs asi hazviwanzo kushanda pamagumo eshinda. Uyezve, kutarisirwa kunodiwa kudzivirira mashing burrs mumipata yeshinda, izvo zvinogona kukanganisa kusangana.

Kana maburrs ari pashinda dzemukati, misa yekupedzisa matekiniki anofanirwa kukwanisa kusvika pakadzika mukati mezvimiro zvemukati.chikamu chendarira

Thermal deburring, semuenzaniso, inoshandisa simba rekupisa rinosvika zviuru zvemadhigirii Fahrenheit kurwisa maburrs kubva kumativi ese. Nekuda kwekuti kupisa hakugone kutamisa kubva paburr kuenda kuchinhu chemubereki, burr rinongopiswa kusvika kune chinhu chemubereki. Saka nekudaro, kupisa kwemafuta hakukanganise chero zviyero, kupera kwepamusoro, kana zvinhu zvechikamu chemubereki.

Electrochemical polishing inoshandiswawo kubvisa uye inoshanda nekuyera chero diki-peaks kana burrs. Kunyangwe iyo tekinoroji inoshanda, pachine kumwe kunetseka kuti inogona kukanganisa tambo. Zvakadaro, kazhinji kutaura, kubviswa kwezvinhu kunopindirana nechimiro chechikamu.

Kunyangwe paine zvingangoitika, mutengo wakaderera wekupedzisa kwakawanda uchiri kuita kuti ive nzira inofadza kune mamwe zvitoro zvemichina. Nekudaro, sezvatocherechedzwa, zvitoro zvemuchina zvinosarudza kuchengeta sekondari maoperation mumba kana zvichibvira.

Miniature deburring brushes — Pazvikamu zvakarukwa uye maburi emuchina asingasviki 0.125 mukati, mabhurashi esimbi madiki chinhu chinokwanisika kubvisa mabhururu madiki uye kukwenenzvera mukati. Miniature mabhurashi anouya akasiyana siyana madiki (kusanganisira kits), contours uye zvinhu. Zvishandiso izvi zvakanyatsokodzera kugadzirisa kushivirira kwakasimba, kusanganiswa kwemupendero, kubvisa uye zvimwe zvinodiwa zvekupedzisa.

"Zvitoro zvemuchina zvinouya kwatiri kuzotsvaga mabhurashi madiki nekuti havachada kuendesa kunze uye vanoda kuita basa iri mumba," akadaro Jonathan Borden, maneja wezvekutengesa weBrush Research Manufacturing. “Nebhurashi diki, havachafanira kunetseka nezve nguva dzekutungamira uye kumwe kurongeka kutumira zvikamu kunze nekuzvidzosa mukati.

Semupi wemutsetse wakazara wepamusoro ekupedzisa mhinduro, BRM inopa madiki ekubvisa mabhurashi mumhando dzakasiyana dzefilament uye tipi masitaera. Iyo kambani diki dhayamita bhurashi inoyera chete 0.014 mukati.

Iyo miniature deburring brushes inogona kushandiswa nemaoko. Nekudaro, nekuti waya dzebhurashi stem dzakanyanya kunaka uye dzinogona kukotama, mugadziri anokurudzira kushandisa pini-vise. BRM inopa mbiri-yekupedzisira pini vise mumakiti ane anosvika gumi nemaviri mabhurashi mune ese madhisimali (0.032 kusvika 0.189 mukati) uye metric hole saizi (1 mm kusvika 6.5 mm).

Mapini mavhisi zvakare anogona kushandiswa kubata madiki mabhurashi edhayamita kuti atenderedze kutenderedzwa pasi pesimba pachibooreso cheruoko uye kunyangwe pamushini weCNC.

Mabhurashi madiki anogonawo kushandiswa pashinda dzekunze, kubvisa mabhururu madiki anogona kuumba panotangira shinda. Aya maburrs anogona kukonzera matambudziko uye anofanirwa kubviswa, nekuti chero simbi inodzingwa inogona kukonzera yakakomba uye inogona kuve nengozi mamiriro mumaindasitiri maapplication ayo anoda kurongeka uye kuchena.

Kuti udzivise kutsauka kwewaya yakamonyoroka hunde yebhurashi, CNC michina inogona kurongwa kuti ishandise iyo chaiyo kudzvanywa uye kumhanya kwekutenderera.

“Idzi mhando dzemabasa ekubvisa – kunyangwe nemabhurashi madiki madiki – anogona kuve otomatiki,†akadaro Borden. “Unogona kushandisa maturusi emuchina weCNC uchishandisa pini vise kana kugadzira adapta.

Kune akati wandei marudzi emadiki mabhurashi aripo nhasi ayo anosiyana kwete muhukuru chete, asiwo filament mhando. Carbon simbi, Stainless simbi, ndarira, naironi uye abrasive yakazadzwa naironi inowanzoshandiswa. Naironi izere-abrasive inogona kunge iine silicon carbide, aluminium oxide, kana diamond abrasive.

Sekureva kwaBorden, naironi inobvongodza inonyanya kushanda pakubvisa mabhura nekuposhesa shinda dzepamusoro uye makona ekumaflank mumakomba ealuminium akatekwa. “Kana ukacheka shinda ine poindi imwe chete muaruminiyamu kana kuti chikamu chakarukwa uchishandisa madhaimondi, pachange paine "fuzz" yakawanda uye rough angle angles dzinoda kukwenenzverwa," akatsanangura kudaro.

Miniature Stainless-Simbi mabhurashi akakurumbira pakubvisa zvine hukasha kwezvinhu zvakaita sesimbi yakakandwa kana simbi, kubvisa machipisi kana kujeka-kuburikidza nemaburrs. Kunyangwe abrasive naironi madiki mabhurashi achiwanikwa ari madiki se0.032 mukati., nekuda kwechimiro chesimbi isina tsvina BRM ikozvino inopa matatu madiki mabhurashi saizi: 0.014, 0.018, uye 0.020 mukati.

Inopawo mabhurashi madiki ekubvisa ane dhaimondi-abrasive filaments yezvinhu zvakaomarara, senge simbi yakaoma, ceramic, girazi, uye aerospace alloys.

“Sarudzo yefilament inoenderana nepamusoro pezvinotsanangurwa, kana paine kudiwa kwesimba rekubvisa zvine hukasha,†akadaro Borden.

Akawedzera kuti zvimwe zvinhu zvinoshanda kumabhurashi madiki anoshandiswa mune otomatiki maapplication anosanganisira RPM yemuchina wemuchina, mitengo yekudyisa, uye optima; kupfeka-hupenyu.

Kunyangwe kudhiraivha kwemukati nekunze tambo diki kunogona kunetsa, kushandisa maturusi akanyatsokodzera kune yakapihwa application kunogona kurerutsa basa uye kuvimbisa maburrs ese anogara achibviswa pachikamu chese. Mukuwedzera, nekudzivisa kubudiswa kwemabasa ekugadzirisa kwechipiri, zvitoro zvemichina zvinogona kuderedza nguva yekushandura uye mutengo pane chikamu.Jeff Elliott is a Torrance, Calif.-based technical writer.
