Hauv kev ua haujlwm siab -kawg cov cuab yeej tsim khoom, hnyav- cov cuab yeej siv tshuab ua haujlwm ua haujlwm tseem ceeb ntawm kev ua kom zoo ntawm cov khoom loj thiab cov khoom siv. Tag nrho cov kev ua tau zoo ntawm cov tshuab no feem ntau nyob ntawm kev ntseeg siab thiab kev ruaj ntseg ntawm lawv cov khoom siv yooj yim.Cov khoom no tsis tsuas yog muab kev txhawb nqa rau tag nrho lub tshuab, tab sis kuj tseem ua lub luag haujlwm rau kev tswj xyuas precision, dynamic rigidity, thiab kev pab lub neej. Lawv qhov zoo ncaj qha txiav txim siab seb lub tshuab cuab yeej tuaj yeem ua tau raws li qhov xav tau ntawm machining nruj.
Cov khoom tseem ceeb ntawm cov khoom hnyav- cov cuab yeej siv lub tshuab ua haujlwm feem ntau suav nrog lub txaj, kem, crossbeam, thiab lub rooj ua haujlwm, thiab feem ntau yog ua los ntawm cov hlau cam khwb cia lossis welded steel qauv. Cam khwb cia hlau qhov chaw, vim lawv zoo heev damping zog, hnav tsis kam, thiab mature casting txheej txheem, yog dav siv nyob rau hauv lub ntsiab load - bearing thiab vibration -resistant qhov chaw. Lawv uniformity ntawm cov qauv, graphite morphology, thiab kev ntxhov siab nyob rau hauv lub xeev txiav txim cov khoom damping yam ntxwv thiab seem stability. Yog hais tias shrinkage porosity, huab cua qhov, los yog residual stress concentration nyob rau hauv casting, microscopic deformation tau yooj yim tshwm sim thaum lub sij hawm ntev - siv, ua rau drift nyob rau hauv precision indicators, As guideway straightness thiab worktable flatness, heev cuam tshuam rau machining sib xws.
Rau welded steel structural foundation Cheebtsam, deformation yuav tsum tau tswj los ntawm tsim nyog weld tsim thiab post-weld kev kho mob los xyuas kom meej tag nrho rigidity. Tsis hais txog ntawm cov khoom, qhov tseeb geometric thiab daim ntawv thiab txoj hauj lwm tolerances ntawm lub hauv paus Cheebtsam yuav tsum nruj me ntsis tswj vim hais tias lawv tsim cov qauv siv ntawm lub tshuab cuab yeej tswj system tom qab sib dhos. Txhua qhov sib txawv yuav raug nthuav dav thaum lub sijhawm ua haujlwm, ua rau cov khoom ua haujlwm tsis zoo lossis cov qauv tsis zoo thiab qhov tseeb ntawm txoj haujlwm.
Tsis tas li ntawd, qhov dynamic rigidity ntawm lub hauv paus Cheebtsam yog qhov tseem ceeb rau lub tshuab cuab yeej kev co kuj. Thaum lub sij hawm siab -kev ceev txiav los yog hnyav- load machining, tsis txaus rigidity ntawm lub hauv paus Cheebtsam yuav yooj yim ua rau resonance, tsis tsuas yog txo cov nto tiav tab sis kuj ua rau kom cov cuab yeej hnav thiab spindle bearing qaug zog. Yog li ntawd, siab -cov hauv paus ntsiab lus zoo yuav tsum tau ua kom zoo dua qub los ntawm kev txheeb xyuas cov ntsiab lus finite kom ua kom muaj zog ntxiv thaum ua kom lub teeb yuag, ua ke nrog kev laus kev kho mob kom tshem tawm cov kev ntxhov siab sab hauv thiab ua kom muaj kev ruaj ntseg thaum lub sij hawm ua haujlwm ntev -.
Kev xyaum qhia tau hais tias tsis saib xyuas qhov zoo ntawm lub hauv paus Cheebtsam yuav ua rau kom ntxov ntxov degradation ntawm tag nrho cov tshuab raug, tsis tu ncua tsis ua hauj lwm, thiab ho nce nqi txij nkawm thiab ntau lawm poob. Tsuas yog los ntawm kev tso qhov zoo ntawm cov khoom tseem ceeb ntawm cov cuab yeej siv tshuab tshawb fawb thiab kev tsim kho thiab tsim khoom, thiab los ntawm kev tswj cov ntaub ntawv nruj me ntsis, txhim kho cov txheej txheem, thiab ntxiv dag zog rau kev sim, peb tuaj yeem tsim lub hauv paus ruaj khov rau qhov siab -kev ua tau zoo ntawm cov cuab yeej siv hnyav{2}} lub luag haujlwm ntawm cov cuab yeej siv tshuab, yog li txhawb nqa lub siab - kev txhim kho zoo ntawm kev lag luam siab -.
