Tshem tawm Microburrs los ntawm cov xov me me | Txhuam Tshawb Fawb Mfg.

Yog tias koj nyeem cov rooj sib tham hauv online koj paub tias muaj ntau qhov kev sib cav txog kev txheeb xyuas cov txheej txheem zoo tshaj plaws rau kev tshem tawm cov burrs uas tsis tuaj yeem tsim thaum lub sij hawm machining ntawm threaded qhov chaw. Internal threads †"txawm txiav, dov los yog txias-tsim â€" feem ntau muaj burrs ntawm lub qhov nkag thiab tawm, ntawm cov xov crests, thiab ntawm feem ntau cov npoo. Cov xov sab nraud ntawm bolts, screws, thiab spindles muaj teeb meem zoo sib xws †"tshwj xeeb tshaj yog thaum pib ntawm cov xov.

Rau qhov loj threaded, burrs tuaj yeem raug tshem tawm los ntawm kev rov qab taug txoj kev txiav, tab sis qhov no ua rau lub sijhawm voj voog rau txhua qhov. Kev ua haujlwm thib ob, xws li hnyav nylon deburring cov cuab yeej lossis tus npauj npaim txhuam kuj siv tau.cnc machining qhov chaw

Txawm li cas los xij, cov kev sib tw nce ntau heev thaum txoj kab uas hla ntawm cov threaded ib feem los yog tapped qhov ntsuas tsawg dua 0.125 nyob rau hauv. Nyob rau hauv cov ntaub ntawv no, microburrs tseem tsim tab sis lawv yog me me txaus uas tshem tawm yog ib qho teeb meem ntawm polishing ntau dua aggressive deburring.

Nyob rau ntawm no, nyob rau hauv tej yam me me, kev xaiv ntawm deburring kev daws teeb meem nqaim heev. Cov txheej txheem txheej txheej yuav raug siv, xws li tumbling, electrochemical polishing thiab thermal deburring, tab sis cov no yuav tsum tau xa tawm ntawm tus nqi ntxiv thiab poob sijhawm.

Rau ntau lub khw muag khoom nws yog qhov zoo dua los ua kom muaj kev ua haujlwm thib ob hauv tsev, suav nrog kev deburring, los ntawm kev siv automation siv CNC tshuab, lossis los ntawm kev siv tes xyaum, lossis txawm tias phau ntawv qhia.yas ntu

Rau cov rooj plaub no muaj cov txhuam me me uas â € "txawm tias lub qia me me, filaments thiab tag nrho qhov ntev â €" tuaj yeem tig tau siv tes xyaum thiab txawm siv adapters ntawm CNC khoom. Tam sim no muaj cov nylon abrasive, carbon steel, stainless hlau thiab pob zeb diamond-abrasive filaments, cov cuab yeej no muaj me me li 0.014 nyob rau hauv., nyob ntawm seb hom filament.

Muab lub peev xwm rau burrs cuam tshuam rau daim ntawv, haum lossis kev ua haujlwm ntawm cov khoom lag luam, cov ceg txheem ntseeg siab yog cov khoom lag luam uas muaj cov xov micro, suav nrog cov khoom siv rau cov watches, tsom iav, xov tooj ntawm tes, digital koob yees duab, luam ntawv Circuit Court boards, precision kho mob cov cuab yeej, thiab aerospace qhov chaw. Cov kev pheej hmoo muaj xws li misalignment ntawm kev sib koom ua ke, teeb meem hauv kev sib dhos, burrs uas tuaj yeem dhau los ua xoob thiab kis kab mob hauv lub cev, thiab txawm tias fastener tsis ua haujlwm hauv thaj chaw.

Cov txheej txheem txheej txheej †"Cov txheej txheem ua tiav ntau yam xws li tumbling, thermal deburring thiab electrochemical polishing tuaj yeem ua tau zoo rau kev tshem tawm qee lub teeb burrs ntawm qhov me me. Tumbling, piv txwv li, tuaj yeem siv los tshem tawm qee qhov burrs tab sis nws tsis yog feem ntau siv rau qhov kawg ntawm cov xov. Tsis tas li ntawd, yuav tsum tau saib xyuas kom tsis txhob mashing burrs rau hauv xov kwj, uas tuaj yeem cuam tshuam nrog kev sib dhos.

Thaum burrs nyob rau hauv cov xov, cov txheej txheem ua tiav ntau yuav tsum muaj peev xwm ncav cuag tob rau hauv cov qauv sab hauv.tooj dag

Thermal deburring, piv txwv li, siv lub zog hluav taws xob uas nce mus txog ntau txhiab degrees Fahrenheit los tua burrs los ntawm txhua sab. Vim tias cov cua sov tsis tuaj yeem hloov los ntawm cov burr mus rau cov khoom siv niam txiv, cov burr tsuas yog hlawv mus rau cov khoom niam txiv. Yog li ntawd, thermal deburring tsis cuam tshuam rau qhov ntev, qhov chaw tiav, lossis cov khoom siv ntawm niam txiv.

Electrochemical polishing kuj tseem siv rau kev deburring thiab ua haujlwm los ntawm kev ua kom muaj qhov micro-peaks lossis burrs. Txawm hais tias cov txheej txheem ua haujlwm tau zoo, tseem muaj qee qhov kev txhawj xeeb tias nws tuaj yeem cuam tshuam cov xov. Tseem, feem ntau hais lus, cov khoom tshem tawm ua raws li cov duab ntawm ib feem.

Txawm hais tias muaj peev xwm muaj teeb meem, tus nqi qis ntawm kev ua tiav loj tseem ua rau nws muaj kev txaus siab rau qee lub khw muag khoom. Txawm li cas los xij, raws li twb tau hais lawm, cov khw muag khoom xav kom ua haujlwm thib ob hauv tsev yog tias ua tau.

Miniature deburring txhuam †"Rau cov xov xov thiab cov tshuab ua qhov tsawg dua 0.125 in., cov txhuam hniav me me yog cov cuab yeej pheej yig los tshem tawm cov burrs me me thiab ua polishing sab hauv. Cov txhuam hniav me me tuaj hauv ntau qhov me me (nrog rau cov khoom siv), contours thiab cov ntaub ntawv. Cov cuab yeej no yog qhov zoo tshaj plaws los daws qhov kev ua siab ntev, kev sib xyaw ntawm ntug, deburring thiab lwm yam uas yuav tsum tau ua tiav.

†"Lub khw muag khoom tuaj rau peb rau cov txhuam me me vim lawv tsis xav tawm cov khoom ntxiv lawm thiab xav ua haujlwm hauv tsev," Jonathan Borden, tus thawj coj muag khoom hauv tebchaws rau Kev Tshawb Fawb Txhuam Hniav. †œNrog cov txhuam me me, lawv tsis tas yuav txhawj txog lub sij hawm txhuas thiab kev sib koom tes ntxiv kom xa cov khoom tawm thiab coj lawv rov qab rau hauv.â€

Raws li tus neeg muag khoom tag nrho ntawm cov kev daws teeb meem saum npoo av, BRM muab cov txhuam hniav me me hauv ntau hom filament thiab cov ntsiab lus. Lub tuam txhab txoj kab uas hla tsawg tshaj plaws txhuam ntsuas tsuas yog 0.014 nyob rau hauv.

Cov txhuam hniav me me tuaj yeem siv los ntawm tes. Txawm li cas los xij, vim hais tias txhuam cov kav hlau zoo heev thiab tuaj yeem khoov, tus tsim tawm pom zoo siv tus pin-vise. BRM muaj ob-kawg tus pin vise hauv cov khoom siv nrog txog 12 txhuam hauv ob qhov zauv (0.032 txog 0.189 nyob rau hauv.) thiab metric qhov ntau thiab tsawg (1 mm txog 6.5 mm).

Cov pin vises kuj tuaj yeem siv los tuav lub taub me me txhuam kom tso cai rau lawv tig mus rau hauv lub zog ntawm lub xov tooj ntawm tes thiab txawm tias ntawm CNC tshuab.

Cov txhuam hniav me me kuj tuaj yeem siv rau ntawm cov xov sab nraud, kom tshem tawm cov burrs me me uas tuaj yeem tsim thaum pib ntawm cov xov. Cov burrs no tuaj yeem ua rau muaj teeb meem thiab yuav tsum tau muab tshem tawm, vim tias cov hlau uas tau hloov pauv yuav ua rau muaj teeb meem loj thiab muaj kev phom sij hauv kev lag luam uas yuav tsum tau muaj qhov tshwj xeeb thiab kev huv.

Txhawm rau tiv thaiv kom tsis txhob muaj kev cuam tshuam ntawm cov hlua khi ntawm cov txhuam hniav, cov cuab yeej CNC tuaj yeem ua haujlwm los siv lub siab thiab kev sib hloov ceev.

†œCov kev ua haujlwm deburring no â € "txawm tias muaj txoj kab uas hla me me txhuam â€" tuaj yeem ua haujlwm tau zoo," Borden hais. “Koj tuaj yeem siv cov cuab yeej ntawm CNC tshuab siv tus pin vise lossis los ntawm kev ua tus adapter.â€

Muaj ntau ntau hom txhuam hniav me me niaj hnub no uas sib txawv tsis yog qhov loj, tab sis kuj yog hom filament. Carbon steel, stainless hlau, tooj dag, nylon thiab abrasive ntim nylon feem ntau yog siv. Abrasive-filled nylon tuaj yeem muaj silicon carbide, aluminium oxide, lossis pob zeb diamond abrasive.

Raws li Borden, abrasive nylon yog tshwj xeeb tshaj yog zoo rau tshem tawm burrs thiab polishing xov peaks thiab flank cov ces kaum nyob rau hauv tapped aluminium qhov. †œYog tias koj txiav ib lub ntsiab lus hauv txhuas los yog ib feem yog threaded siv pob zeb diamond tooling, yuav muaj ntau ‘fuzz’ thiab ntxhib xov flank cov ces kaum uas yuav tsum tau polished,” nws piav qhia.

Miniature stainless-steel txhuam yog nrov rau kev txhoj puab heev deburring ntawm cov ntaub ntawv xws li cam khwb cia hlau los yog hlau, kom tshem tawm cov chips los yog clear break-los ntawm burrs. Txawm hais tias abrasive nylon me txhuam txhuam muaj me me li 0.032 nyob rau hauv., vim qhov xwm ntawm stainless hlau BRM tam sim no muaj peb txhuam me me: 0.014, 0.018, thiab 0.020 hauv.

Nws tseem muab cov txhuam hniav me me nrog pob zeb diamond-abrasive filaments rau cov ntaub ntawv nyuaj, xws li cov hlau tawv, ceramic, iav, thiab aerospace alloys.

†œKev xaiv ntawm filament nyob ntawm qhov chaw ua tiav qhov tshwj xeeb, lossis yog tias muaj kev xav tau rau lub zog ua kom muaj zog me ntsis ntxiv, Borden hais.

Nws hais ntxiv tias lwm yam uas siv rau cov txhuam hniav me me uas siv rau hauv cov ntawv siv automated muaj xws li RPM ntawm lub tshuab cuab yeej, tus nqi pub, thiab optima; hnav-lub neej.

Txawm hais tias deburring ntawm sab hauv thiab sab nraud micro threads tuaj yeem nyuaj, siv cov cuab yeej tsim nyog tshaj plaws rau daim ntawv thov tuaj yeem ua kom yooj yim rau txoj haujlwm thiab paub tseeb tias tag nrho cov burrs raug tshem tawm tas li ntawm txhua qhov. Tsis tas li ntawd, los ntawm kev zam kom tsis txhob muaj kev cuam tshuam ntawm kev ua haujlwm thib ob, cov khw muag khoom tuaj yeem txo lub sijhawm hloov pauv thiab tus nqi ib feem.Jeff Elliott yog Torrance, Calif.-based technical writer.
