Txhawm rau txhim kho qhov ua tau zoo ntawm CNC tig workpieces, nws yog ib qho tseem ceeb rau xaiv cov hniav, tshwj xeeb tshaj yog cov arc loj ntawm cov hniav ntug.
Raws li peb txhua tus paub, txiav lub sij hawm yog inversely proportional rau tus nqi ntawm cov cuab yeej pub. Txhawm rau kom txo lub sijhawm txiav, ib qho ntxig nrog lub txiav ntug loj yuav tsum tau siv thaum ua tau.
Nws raug nquahu kom siv cov khoom siv puag ncig thaum txiav cov chaw tiaj tus ntawm cov khoom ua haujlwm xws li sab hauv thiab sab nrauv yam tsis muaj kauj ruam.
Daim duab hauv qab no qhia tau hais tias φ12 ib leeg-sab ncig hniav.
duab
piv txwv. Ib qho chaw sab nrauv yuav tsum tau tig mus rau qhov roughness ntawm 6.4.
Yog tias R1.2 80-degree lossis 55-degree lossis daim duab peb sab yog siv los tig, lub cuab yeej pub yuav tsum tsis txhob siab tshaj 0.174mm ib kiv puag ncig (saib daim duab 1).
duab
Yog tias koj siv φ10 lub voj voog tig hloov, lub cuab yeej pub tus nqi yuav tsis ntau tshaj 0.452mm (saib daim duab 2).
duab
Piv nrog rau cov khoom siv R1.2, kev txiav ceev kom ua tiav tib yam roughness tuaj yeem nrawm mus rau 2.6 npaug, uas yog, qhov kev ua haujlwm tau nce mus rau 2.6 npaug.
Lwm qhov kom zoo dua ntawm kev siv cov hniav puag ncig yog tias nws muaj qhov txiav ntug tag nrho ib puag ncig thiab tuaj yeem ntsuas thiab rov siv dua tom qab hnav, uas tuaj yeem txuag tau tus nqi ntawm cov hniav noj.
Lub txiav quab yuam ntawm puag ncig inserts yog loj, uas yuav tsum tau siab rigidity ntawm lub tshuab cuab yeej thiab cov txheej txheem txheej txheem. Tsis muaj qhov tsis ntseeg tias CNC lathes, tshwj xeeb tshaj yog tag nrho-function CNC lathes, yog nruj heev.
Peb pom tias kev siv cov hniav puag ncig txawv teb chaws ntau dua li kev siv cov hniav qub hauv Suav teb.
Peb tau pom nyob rau hauv Japanese tuam txhab uas muag lawv kuj siv round hniav thaum ntxhib tig tiaj tiaj ntawm workpieces. Yog li ntawd yog vim li cas peb tsis txhob twv yuav tsum siv round inserts thaum ua tiav lub tiaj tiaj ntawm workpiece?
Thaum siv cov hniav puag ncig, kev saib xyuas yuav tsum tau them rau lub rigidity ntawm lub clamp. Tsis yog txhua qhov xwm txheej tuaj yeem siv cov hniav puag ncig. Piv txwv li, yog hais tias lub workpiece muaj ib tug stepped nto, koj yuav siv tsis tau ib tug round hniav. Round blades kuj tsis haum rau tig nyias-walled qhov chaw los yog slender shafts.
