Dab tsi yog qhov seem haum rau precision machining

Peb paub tias precision machining muaj siab yuav tsum tau ua precision, precision machining tau zoo rigidity, siab ua qhov cuab yeej raug, thiab qhov cuab yeej teev, yog li nws tuaj yeem ua cov khoom siv nrog cov siab precision. Yog li dab tsi yog qhov chaw haum rau precision machining? Hauv qab no yog qhia los ntawm Xiaobian:

Ua ntej txhua yam, piv rau cov lathes zoo tib yam, CNC lathes muaj cov kab sib nrawm txiav txiav muaj nuj nqi, tsis hais lub tshuab dhos lub ntsej muag kawg lossis sab nraud ntawm cov diameters sib txawv tuaj yeem ua tiav ntawm tib kab ceev, uas yog kom ntseeg tau tus nqi saum npoo tsis zoo. thiab kuj me me. Lub tshuab dhos dog dig muaj qhov ceev ceev, thiab qhov txiav ceev txawv nrog lub taub. Thaum cov khoom ntawm lub workpiece thiab cov cuab yeej, qhov kawg pub nyiaj thiab lub cuab tam lub kaum ntse ntse tas li, qhov saum npoo ntawm qhov sib txawv yog nyob ntawm qhov txiav ceev thiab pub nrawm.

Thaum ua cov txheej txheem nrog cov nplaim sib txawv hauv pem teb, qhov kev pub zaub mov me yog siv rau ib qho chaw nrog qhov me me, thiab qhov kev pub noj ntau dua yog siv rau saum npoo nrog qhov loj ntawm qhov loj, uas muaj qhov hloov pauv zoo, uas nyuaj rau qhov ua tiav ntawm lathes dog dig Cov. Comoured ntu qhov chaw. Lub dav hlau nkhaus tuaj yeem kwv yees tau los ntawm txoj kab ncaj nraim lossis lub xov ncig. CNC precision machining muaj kev ua haujlwm ntawm txoj kev txhais, uas tuaj yeem ua cov txheej txheem ntau ntawm cov khoom sib txawv. Kev siv cnc precision machining yuav tsum tau tus neeg teb xov tooj kom siv ceev faj.

CNC precision machining mas suav nrog zoo tig, nplua tho, zoo milling, zoo sib tsoo thiab sib tsoo cov txheej txheem:

(1) Kev ua kom zoo thiab ua kom zoo nkauj: Feem ntau qhov tseeb lub teeb pom kev zoo (aluminium lossis magnesium alloy) seem ntawm cov dav hlau tau ua los ntawm hom no. Lub ntuj pob zeb diamond siv cov cuab yeej feem ntau siv, thiab cov xov tooj hluav taws xob npoo ntawm cov hniav plooj yog tsawg dua 0.1 micron. Machining ntawm lub tshuab dhos ua hauj lwm siab tuaj yeem ua tiav 1 micron qhov tseeb thiab qhov tsis ncaj saum npoo nrog qhov nruab nrab qhov siab sib txawv ntawm tsawg dua 0.2 micron, thiab kev koom ua ke raug qhov tseeb tuaj yeem ncav cuag ± 2 micron.

(2) Zoo milling: siv rau kev siv tshuab txhuas lossis beryllium alloy cov yam ntxwv nrog cov qauv duab. Ua raws li qhov tseeb ntawm cov lus qhia thiab ntxaiv ntawm lub tshuab cuab yeej kom tau txais kev sib nrig dua txoj hauj lwm ua haujlwm raug. Kev kub ceev milling nrog cov lus qhia txog pob zeb diamond nrum ntsej muag rau cov iav ncaj iav.

(3) Kev sib tsoo zoo: siv rau kev siv lub tshuab ua haujlwm lossis ua lub qhov. Feem ntau ntawm cov seem yog ua los ntawm cov tawv tawv tawv thiab muaj lub siab tawv. Feem ntau high-precision sib tsoo tshuab ntxaiv siv hydrostatic lossis dynamic siab ua kua bearings kom ntseeg tau tias ruaj khov. Ntxiv nrog rau qhov cuam tshuam ntawm kev nruj ntawm lub tshuab cuab yeej ntxaiv thiab lub txaj, qhov kawg qhov tseeb ntawm kev sib tsoo tseem muaj feem xyuam nrog kev xaiv thiab sib npaug ntawm lub sib tsoo thiab cov machining qhov tseeb ntawm qhov chaw ntawm lub chaw ua haujlwm. Kev sib tsoo zoo tuaj yeem ua tiav qhov tseeb ntawm 1 micron thiab sab nraud ntawm 0.5 micron.

(4) Kev Sib Tsoo: Xaiv thiab ua cov tsis tu ncua tsa cov seem nyob rau saum npoo kom tau ua tiav siv cov cai ntawm kev sib nrig sib tshawb ntawm cov ntu. Abrasive particle inch, txiav quab yuam thiab txiav cov khoom cua sov tuaj yeem tswj tau qhov tseeb, yog li nws yog cov kev ua haujlwm tshaj plaws hauv kev ua haujlwm hauv qhov tseeb machining tshuab. Cov chaw nres tsheb hydraulic lossis pneumatic mating ua qhov tshwj xeeb servo qhov chaw ntawm lub dav hlau thiab cov kabmob qhov chaw ntawm lub zog siab gyro tsav tau tag nrho cov txheej txheem nyob rau hauv txoj kev no kom ua tiav qhov tseeb ntawm 0.1 lossis 0.01 micron thiab micro tsis sib luag ntawm 0.005 micron.
