General mechanical machining khoom siv dav siv hauv ntau qhov xwm txheej. Yog li, ib lo lus nug tsim nyog tshawb nrhiav tshwm sim: Cov cuab yeej siv tshuab machining tuaj yeem ua cov txheej txheem kev ua haujlwm zoo li cas?
I. Cov yam ntxwv thiab kev txwv ntawm General Mechanical Machining Equipment
(1) Precision
General mechanical machining cov cuab yeej, xws li cov tshuab dhos zoo tib yam, tshuab milling, thiab cov tshuab drilling, muaj qhov tsawg tsawg. Piv txwv li, ib lub tshuab dhos raug yuav muaj qhov tseeb ntawm ib puag ncig ± 0.05mm thiab rov ua dua ntawm ± 0.03mm. Qib no ntawm qhov tseeb yog txaus rau cov khoom siv sib xyaw ua ke, xws li cov shafts thiab disc - zoo li cov khoom, kom ua tau raws li qhov yuav tsum tau ua. Txawm li cas los xij, precision mechanical Cheebtsam feem ntau xav tau qhov tseeb qhov tseeb. Piv txwv li, nyob rau hauv aerospace teb, ib co Cheebtsam yuav tolerances tswj nyob rau hauv ± 0.01mm los yog txawm me me. Lub precision ntawm lub tshuab dhos dav dav tsis txaus kom ua tau raws li qhov yuav tsum tau ua nruj me ntsis, thiab cov khoom ua tiav nrog nws yuav muaj qhov sib txawv ntawm qhov loj me, ua tsis tau raws li cov qauv precision ntawm precision mechanical Cheebtsam.
(2) Kev ruaj ntseg
General mechanical machining cov cuab yeej tsis ruaj khov thaum lub sijhawm ua haujlwm piv rau cov cuab yeej tshwj xeeb precision machining. Tom qab lub sijhawm ua haujlwm ntev, yam xws li cov khoom siv coj los siv thiab rov qab rau hauv cov kab ke sib kis tuaj yeem maj mam degrade machining raug. Piv txwv li, tom qab ob peb teev ntawm kev ua haujlwm tas mus li, lub tshuab milling tuaj yeem ntsib qee qhov kev sib txawv ntawm cov cuab yeej. Qhov kev sib txawv no yuav tsis cuam tshuam rau qhov chaw nrog qis dua qhov yuav tsum tau ua, tab sis rau cov khoom siv tshuab ua kom zoo, txawm tias me me sib txawv tuaj yeem ua rau cov duab thiab qhov tseeb qhov tseeb tshaj qhov txwv.
(3) Automation Qib thiab Tswj Precision
General mechanical machining cov cuab yeej feem ntau muaj qib qis ntawm automation, nrog rau ntau yam kev ua haujlwm raws li kev tswj xyuas phau ntawv. Inconsistencies nyob rau hauv phau ntawv ua hauj lwm yuav qhia tau yuam kev. Txawm hais tias qee cov cuab yeej muaj qee yam kev ua haujlwm tsis siv neeg, qhov tseeb thiab cov lus teb ceev ntawm nws cov kev tswj hwm tseem ua rau cov khoom siv precision machining. Piv txwv li, thaum lub sij hawm complex contour machining hauj lwm, ib tug dav CNC machining chaw yuav tawm tsam kom raug raws li me me contour nkhaus vim nws txwv interpolation precision, tsis ua tau raws li siab -precision contour machining yuav tsum tau precision mechanical Cheebtsam.
II. Tshwj xeeb yuav tsum tau rau Precision Mechanical Cheebtsam Machining
(1) High Precision Requirements
Precision mechanical Cheebtsam machining xav tau siab heev nyob rau hauv cov nqe lus ntawm dimensional precision, zoo precision, thiab nto roughness. Raws li tau hais ua ntej, qee qhov tseem ceeb ntawm cov khoom muaj kev zam nruj heev. Nyob rau hauv cov nqe lus ntawm cov duab precision, lub Cheebtsam xws li precision pwm kab noj hniav thiab aircraft cav hniav yuav tsum tau cov duab tsis zoo (xws li, flatness, cylindricity, roundness) yuav tsum tau tswj nyob rau hauv lub micrometer theem. Hais txog qhov roughness ntawm qhov chaw, piv txwv li, nyob rau hauv lub machining ntawm optical lo ntsiab muag, qhov nto roughness Ra tus nqi feem ntau yuav tsum nyob nruab nrab ntawm 0.01μm thiab 0.02μm. Xws li qhov chaw du yog qhov nyuaj rau kev ua tiav nrog cov cuab yeej siv tshuab machining.
(2) Cov txheej txheem nyuaj
Precision mechanical Cheebtsam feem ntau xav tau cov txheej txheem machining. Piv txwv li, cov khoom uas muaj qhov me me, qhov tob, lossis cov qauv tsis sib xws yuav xav tau cov txheej txheem tshwj xeeb xws li hluav taws xob tawm machining (EDM), electrochemical machining (ECM), thiab laser machining. Cov txheej txheem tshwj xeeb no xav tau cov cuab yeej siv siab thiab kev txhawb nqa, uas cov cuab yeej siv tshuab machining feem ntau tsis muaj, ua rau nws tsis tuaj yeem ua tiav cov haujlwm machining sib xws. Ntxiv mus, txoj kev npaj ntawm machining txheej txheem txoj kev rau precision Cheebtsam yog ntau complex thiab meticulous, yuav tsum tau txiav txim siab ntawm qhov cuam tshuam ntawm machining sequence ntawm ib feem raug thiab residual stress. Qhov no yog lwm qhov kev sib tw uas cov cuab yeej siv tshuab machining feem ntau ntsib thaum ua cov khoom precision.
(3) Environmental Requirements
Precision mechanical Cheebtsam machining feem ntau muaj cov cai nruj rau qhov chaw machining. Cov yam ntxwv xws li kub, av noo, thiab kev co tuaj yeem cuam tshuam qhov tseeb ntawm machining. Piv txwv li, thaum lub sij hawm ultra- precision machining, txawm me me qhov kub thiab txias hloov tuaj yeem ua rau thermal expansion thiab contraction ntawm cov khoom thiab cov khoom, yog li cuam tshuam rau machining raug. Lub rhiav ib puag ncig uas cov cuab yeej siv tshuab machining feem ntau tsis muaj kev tswj qhov kub thiab txias, tswj cov av noo, thiab kev sib cais ntawm kev vibration, ua rau nws nyuaj rau ua kom tau raws li ib puag ncig cov kev cai rau precision mechanical Cheebtsam machining.
