Machining ntawm hlau: hom thiab cov hau kev

Machining - ib tug txheej txheem thaum lub sij hawm uas hloov qhov luaj li cas thiab configuration ntawm lub daim thiab qhov chaw. Yog hais tias peb tham txog cov hlau cov khoom, rau lawv cov ua siv tshwj xeeb tej cuab yeej, xws li cutters, broaches, hnyiab, cov kais dej, milling cutters, thiab lwm yam ... Tag nrho cov ua hauj lwm yog ua rau lub tshuab cov cuab yeej raws li lub routing. Nyob rau hauv no tsab xov xwm, peb yuav kawm tau dab tsi yog txoj kev thiab cov ntaub ntawv ntawm hlau machining.

ua txoj kev

Machining yog muab faib ua ob pawg loj. Tus thawj muaj cov neeg ua haujlwm uas tshwm sim tsis tshem hlau. Cov no muaj xws forging, stamping, nias, dov. Qhov no thiaj li hu ua cov neeg kho tshuab kev kho mob siv ib tug siab los yog poob siab. Nws yog siv los muab cov kev tsim nyog daim ntawv workpiece. Rau uas tsis yog-ferrous co feem ntau siv forging, thiab rau dub - stamping.

Qhov thib ob pab pawg neeg no muaj xws li lub lag luam nyob rau hauv uas lub preform yog muab tshem tawm nrog ib daim ntawm cov hlau. Qhov no yog tsim nyog los muab nws yuav tsum tau me me. Qhov no machining ntawm hlau tej no yog hu ua thiab tua nrog kev pab los ntawm lub tshuab cov cuab yeej. Feem ntau kev kho mob txoj kev muaj txoj siav, drilling, reaming, sib tsoo, milling, reaming, chiselling, planing thiab Broaching.

Yuav ua li cas txiav txim rau lub hom ntawm kev kho mob

Fabrication ntawm cov hlau ib feem ntawm lub workpiece - ib lub sij hawm siv thiab es nyuab txheej txheem. Nws muaj xws li ib tug plurality ntawm txawv ua hauj lwm. Ib tug ntawm lawv yog cov machining ntawm hlau. Ua ntej koj yuav pib mus rau nws, roos ib tug hauj daim ntawv qhia thiab ua ib qho ntawm lub tiav lawm ib feem uas qhia tag nrho yuav tsum tau ntev thiab raug cov chav kawm ntawv. Nyob rau hauv tej rooj plaub, raws li npaj rau intermediate cais duab ua hauj lwm.

Tsis tas li ntawd, muaj roughing, finishing thiab machining ntawm hlau. Rau txhua ntawm lawv laij tej yam kev mob thiab nyiaj. ib tug hlau ua hom feem ntau nyob rau cov kev kho mob nto raug chav kawm ntawv roughness tsis thiab ib feem qhov ntev. Piv txwv li, rau qhov ntawm H11 yog siv rau qib ntxhib drilling ntawm ib tug xyaum, thiab rau xa mus nyob rau hauv lub 3-ntshiab qib raug siv tau scan los yog Countersink. Tom ntej no, peb yuav kawm txog txoj kev rau cov neeg kho tshuab ua ntawm co nyob rau hauv ntau yam.

Raws thiab drilling

Raws yog ua rau lub tshuab cov cuab yeej ntawm tus raws pab pawg neeg los ntawm kev siv lub incisors. Lub preform yog mounted rau hauv ib lub ntxaiv uas yog rotated ntawm ib tug predetermined ceev. Ib tug cutter mounted nyob rau hauv ib tug them nyiaj yug, ua longitudinal transverse tsab ntawv tsa suab. Tus tshiab CNC-machines, tag nrho cov ntaub ntawv tsis muab ntaus rau hauv lub computer, thiab ntaus nws tus kheej yog ib tug tsim nyog lub lag luam. Nyob rau hauv cov laus ua qauv, xws li 16K20 longitudinal thiab transverse taw yog nqa tawm manually. Nyob rau lathes tau xa zoo li tus, conical thiab cylindrical chaw.

Boring - ib lub lag luam uas yog ua los ua tus qhov. Lub ntsiab ua hauj lwm cov cuab tam yog ib tug xyaum. Feem ntau, cov xyaum tsis muab ib tug high school cov qib ntawm cov neeg thiab yog tog twg los roughing los yog finishing. Rau qhov Qualitet hauv qab no H8 siv txiag, reaming, boring thiab reaming. Nyob rau hauv tas li ntawd, tom qab tus drilling kuj ua tapping. Qhov no cov neeg kho tshuab hlau ua yog ua siv tus kais thiab tej hom ntawm cutters.

Milling thiab sib tsoo

Milling - ib qho ntawm feem nthuav txoj kev ntawm cov zauv co. Qhov no lub lag luam yog ua los ntawm ib tug ntau yam ntawm cutters rau milling machine. Paub qhov txawv kawg, zoo li tus, kawg, thiab ib tug peripheral ua. Milling yuav ua tau ob qho tib si roughing thiab semi thiab finishing. Tsawg tshaj plaws Qualitet raug tau thaum tag - 6. Siv txawv cutters machined splines, grooves, qhov dej, undercuts, as profiles.

Sib Tsoo - phau ntawv lub lag luam siv rau koj ntxiv kom qhov zoo ntawm cov roughness, thiab kuj rau kev tshem tawm ntawm tshaj hlau txheej mus rau ib micron. Feem ntau, qhov no kev kho mob yog cov theem kawg rau qhov siv thiab ntawm qhov chaw thiab, li no, yog finishing. Rau tej ntawm sib tsoo log yog siv, rau ntawm qhov chaw uas yog ib tug lossis loj npaum li cov nplej muaj ib tug txawv cov duab ntawm tej ntug. Nyob rau hauv qhov kev kho no, qhov khoom no puas kub heev. Nyob rau hauv kev txiav txim hais tias tus hlau yuav tsis warp los yog nadkololsya siv coolants (Sorges). Machining uas tsis yog-ferrous co yog nqa tawm los ntawm txhais tau tias cov pob zeb diamond cov cuab yeej. Qhov no saib kuas qhov zoo tshaj plaws tau zoo ntawm manufactured qhov chaw.
