CNC machining ntawm yas qhov chaw

Txawm tiasCNC machiningntawm cov khoom yas yog ib qho yooj yim los txiav, nws kuj muaj qee qhov teeb meem, xws li yooj yim deformation, tsis zoo thermal conductivity, thiab rhiab heev rau txiav quab yuam, nws cov neeg ua tiav tsis tau lees paub, vim tias nws yooj yim los cuam tshuam los ntawm qhov kub thiab txias, thiab nws kuj yog ib qho yooj yim los tsim deformation hauv kev ua, tab sis peb muaj txoj hauv kev los daws nws. Ceev faj rauCNC machining ntawm yas qhov chaw:

1. Cov cuab yeej xaiv:

• Raws li cov khoom siv yas yog mos, cov cuab yeej ntse yuav tsum tau xaiv. Piv txwv li, rau ABS yas prototypes, cov cuab yeej carbide nrog cov npoo ntse tuaj yeem txo cov kua muag thiab burrs thaum ua haujlwm.

• Xaiv cov cuab yeej raws li cov duab thiab nthuav dav qhov nyuaj ntawm tus qauv. Yog tias tus qauv tsim muaj cov qauv tsim los yog qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob.

2. Txiav parameter nqis:

• Txiav ceev: Lub melting point ntawm yas yog kuj tsawg. Txiav ceev heev tuaj yeem yooj yim ua rau cov yas overheat thiab yaj. Feem ntau hais lus, kev txiav ceev tuaj yeem nrawm dua li cov khoom siv hlau machining, tab sis yuav tsum tau hloov kho raws li hom yas tshwj xeeb thiab cov cuab yeej siv. Piv txwv li, thaum ua cov khoom siv polycarbonate (PC) cov qauv, kev txiav ceev tuaj yeem teem caij nyob ib ncig ntawm 300-600m / min.

•Feed ceev: Tsim nyog pub ceev tuaj yeem ua kom zoo. Kev pub noj ntau dhau yuav ua rau lub cuab yeej dais lub zog txiav ntau dhau, ua rau txo qis ntawm cov qauv saum npoo zoo; tus nqi pub me me dhau lawm yuav txo qis kev ua haujlwm. Rau cov qauv yas zoo tib yam, kev pub ceev tuaj yeem nyob nruab nrab ntawm 0.05 - 0.2 hli / hniav.

• Txiav qhov tob: qhov txiav qhov tob yuav tsum tsis txhob tob dhau; txwv tsis pub, loj txiav quab yuam yuav raug tsim, uas yuav deform los yog tawg tus qauv. Raws li ib txwm muaj, nws raug pom zoo tias qhov tob ntawm ib qho kev txiav yog tswj ntawm 0.5 - 2 hli.

3. Xaiv txoj kev clamping:

• Xaiv txoj kev clamping uas tsim nyog kom tsis txhob ua rau tus qauv tsim. Cov ntaub ntawv mos xws li cov ntaub qhwv roj hmab tuaj yeem siv los ua cov txheej txheem sib txuas ntawm cov clamp thiab cov qauv los tiv thaiv kev puas tsuaj ntawm clamping. Piv txwv li, thaum clamping tus qauv nyob rau hauv ib lub vise, muab cov roj hmab ncoo rau ntawm lub puab tsaig tsis tsuas yog clamps tus qauv kom ruaj ntseg tab sis kuj tiv thaiv nws nto.

• Thaum clamping, xyuas kom muaj kev ruaj ntseg ntawm tus qauv tiv thaiv kom tsis txhob txav chaw thaum ua haujlwm. Rau cov qauv tsis zoo li qub, kev cai fixtures lossis kev sib xyaw ua ke tuaj yeem siv los ua kom lawv txoj haujlwm ruaj khov thaum ua haujlwm.

4. Kev npaj ua ntu zus:

• Feem ntau hais lus, machining ntxhib yog ua ua ntej kom tshem tawm feem ntau ntawm cov nyiaj pub dawb, tawm ntawm 0.5 - 1 hli nyiaj rau kev ua tiav. Roughing tuaj yeem siv cov txiav loj dua los txhim kho kev ua haujlwm zoo.

• Thaum ua tiav, yuav tsum tau them nyiaj mloog kom ntseeg tau tias qhov tseeb qhov tseeb thiab qhov zoo ntawm tus qauv. Rau cov qauv uas muaj qhov zoo dua qhov yuav tsum tau ua, cov txheej txheem ua tiav kawg tuaj yeem npaj tau, xws li milling nrog me me pub ceev, qhov tob me me ntawm kev txiav, lossis siv cov cuab yeej polishing rau kev kho saum npoo.

5. Kev siv cov dej txias:

•Thaum ua cov qauv yas, ceev faj thaum siv cov dej txias. Qee cov yas yuav ua rau muaj tshuaj lom neeg nrog cov khoom ua kom txias, yog li xaiv cov khoom ua kom zoo. Piv txwv li, rau polystyrene (PS) prototypes, tsis txhob siv cov coolants uas muaj qee cov organic solvents.

•Lub luag haujlwm tseem ceeb ntawm cov dej txias yog txias thiab lubrication. Thaum lub sij hawm machining txheej txheem, qhov tsim nyog coolant tuaj yeem txo qhov kub thiab txias, txo cov cuab yeej hnav, thiab txhim kho machining zoo.
