Raws li cov cuab yeej tseem ceeb rau kev ua tiav qib siab - cov khoom raug tshem tawm thiab tsim, tag nrho cov kev ua tau zoo thiab kev pabcuam lub neej ntawm lub tshuab machining feem ntau nyob ntawm cov ntaub ntawv tseem ceeb siv. Cov ntaub ntawv tsis tsuas yog txiav txim siab lub tshuab cuab yeej zoo li qub thiab dynamic rigidity, thermal stability, thiab kev co tsis kam, tab sis kuj cuam tshuam ncaj qha rau kev saib xyuas ntawm machining raug thiab ntev -lub sij hawm kev cia siab. Yog li ntawd, kev xaiv thiab kev ua tau zoo sib xws ntawm cov khoom siv rau cov khoom tseem ceeb ntawm lub tshuab machining yog ib qho teeb meem tseem ceeb hauv kev tsim thiab kev tsim khoom.
Basic load-cov kabmob xws li lub txaj, kem, thiab crossbeam feem ntau yog ua los ntawm siab - lub zog cam khwb cia hlau lossis granite. Grey cam khwb cia hlau, vim nws cov yam ntxwv zoo damping thiab casting machinability, tuaj yeem nqus tau kev co thaum lub sij hawm txiav, txhim kho machining stability; nws sab hauv flake graphite qauv tuaj yeem tsis cuam tshuam cov loads thiab ncua kev qaug zog tawg tawm. Qee cov qauv siab -precision qauv siv Meehanite cam khwb cia hlau los yog ductile hlau, nrog rau kev txhim kho ntxiv ntawm lub zog thiab hnav tsis kam los ntawm alloy muaj pes tsawg leeg thiab kev kho cua sov kom zoo. Granite, vim nws tsis tshua muaj coefficient ntawm thermal expansion thiab zoo heev dimension stability, yog siv nyob rau hauv ultra- precision machining chaw los yog kev sib koom tes ntsuas cov cuab yeej uas yog rhiab heev rau qhov kub thiab txias drift, tswj micron - theem geometric raug sab nraud ntawm qhov tsis tu ncua - qhov kub thiab txias.
Cov kev taw qhia thiab cov swb feem ntau yog ua los ntawm cov qib siab - zoo alloy steel nrog kev kho deg hardening. Cov khoom siv feem ntau muaj xws li carburized thiab quenched steel lossis nitrided steel. Cov ntaub ntawv no muab cov tawv tawv tawv nrog cov tub ntxhais toughness, tiv taus hnav thiab yas deformation ntawm txoj kev taw qhia saum npoo thiab ua kom ntseeg tau qhov ncaj thiab kev sib cuag rigidity ntawm cov khoom txav thaum lub sij hawm ntev - siv. Rau siab -ceev, lub teeb- qauv qauv, aluminium alloys thiab cov ntaub ntawv sib xyaw kuj siv los txo qhov txav mus los, tab sis kev txhawb nqa tav thiab siab - cov qauv kev txhawb nqa rigidity yuav tsum tau them nyiaj rau qhov tsis txaus rigidity.
Cov kev xav tau ntawm cov khoom siv hauv kev sib dhos spindle yog nruj tshwj xeeb, feem ntau siv siab -lub zog alloy steel lossis qib steel tshwj xeeb. Cov tub ntxhais spindle feem ntau yog ua los ntawm chromium-molybdenum alloy steel lossis carburized steel, tempered thiab nto siab- zaus quenched kom tau txais kev qaug zog thiab hnav tsis kam. Txhawm rau hloov mus rau lub zog centrifugal thiab thermal load thaum lub sij hawm siab -kev sib hloov ceev, qee qhov siab -kawg spindles siv siab- lub zog stainless hlau lossis titanium alloy los txo qhov hnyav thiab txhim kho corrosion. Cov kabmob vaj tse thiab lub tes tsho yog ua los ntawm cov hlau cam khwb cia hlau lossis lub tes tsho preloaded kom ntseeg tau tias cov kabmob sib dhos raug thiab txhawb nqa rigidity.
Cov khoom sib kis xws li cov ntsia hlau lead, racks, thiab cov iav feem ntau yog ua los ntawm chromium-molybdenum alloy steel los yog carburized steel, thiab dhau los ua kev sib tsoo thiab qhov tawv tawv kom ntseeg tau tias kev sib kis tau raug thiab hnav lub neej. Pob screws, vim lawv xav tau los tiv thaiv rov qab loads thiab siab - nrawm nrawm, xav tau cov khoom siv nrog qhov zoo ntawm qhov ruaj khov thiab qaug zog tiv thaiv kom tsis txhob muaj kev cuam tshuam rov qab thiab nce rov qab rov qab.
Nrog rau qhov sib txawv ntawm kev sib sib zog nqus thiab cov qauv sib xyaw, carbon fiber reinforced composite cov ntaub ntawv thiab honeycomb sandwich qauv tau pib siv rau hauv cov khoom tsis yog -load- cov kabmob xws li cov neeg tiv thaiv thiab cov rooj ua haujlwm. Qhov no tuaj yeem txo qhov loj ntawm qhov txav mus los thiab txhim kho cov lus teb zoo, tab sis cov teeb meem ntawm thermal expansion txuam nrog cov hlau ncej thiab kev sib txuas kev ntseeg siab yuav tsum tau hais txog.
Zuag qhia tag nrho, kev xaiv cov ntaub ntawv tseem ceeb rau cov chaw machining yog tsom rau kev nruj, damping, hnav tsis kam, thermal stability, thiab cov txheej txheem hloov tau. Cov khoom sib txawv tau teeb tsa txawv raws li lawv qhov kev ntxhov siab thiab kev ua haujlwm. Cov khoom siv sib xyaw ua ke tsis yog tsuas yog muab lub hauv paus ruaj khov rau cov cuab yeej siv tshuab, tab sis kuj tseem ua kom lawv tuaj yeem ua haujlwm tsis tu ncua siab -precision thiab siab- kev ntseeg tau ntawm machining peev xwm nyob rau hauv kev ua haujlwm nyuaj, txhawb kev lag luam niaj hnub tsim kev lag luam txuas ntxiv mus kom zoo thiab ua haujlwm tau zoo.
