Lub chaw machining feem ntau tuaj yeem muab faib ua ob ntu: cov cuab yeej siv tshuab (mechanical part) thiab tswj qhov system (qhov hluav taws xob). Lub tshuab cuab yeej yog lub cev tseem ceeb ntawm lub tshuab machining, thiab kev tswj xyuas yog lub hauv paus ntawm machining chaw. Lub chaw machining feem ntau muaj cov khoom siv yooj yim (txaj, workbench, kem), spindle Cheebtsam, CNC system, tsis siv neeg hloov cuab yeej thiab cov cuab yeej pabcuam.
(Cov kab lus no raug xaiv los ntawm Tshooj 2, Tshooj 2 ntawm "Machining Center Selection Guide" Basic Parts and Basic Components of the Machining Center)
2. Workbench thiab workbench Cheebtsam
Hauv GB / T 6477-2008, lub workbench txhais tau tias yog lub rooj zaum ua haujlwm uas muaj qhov chaw ua haujlwm thiab siv ncaj qha los yog tsis ncaj qha rau clamp workpieces lossis cov cuab yeej. Lub workbench yog qhov tseem ceeb tshaj plaws ntawm cov machining chaw. Nws yog qhov ntsuas rau kev teeb tsa ntawm workpieces thiab fixtures. Nws qhov tseeb thiab rigidity yuav cuam tshuam ncaj qha rau kev ua haujlwm zoo ntawm lub workpiece. Cov khoom no yuav tsum tiv taus lub zog clamping ntawm lub workpiece thiab txiav quab yuam, dabtsi yog khoov lub sij hawm thiab torques generated thaum lub sij hawm machining txheej txheem. Yog li ntawd, lub workbench thiab workbench Cheebtsam yuav tsum muaj high precision thiab rigidity.
1. Workbench loj thiab qauv
Qhov dav ntawm lub workbench yog lub ntsiab parameter ntawm lub tshuab cuab yeej. Peb lub teb chaws tau hais tias qhov dav series ntawm machining center workbench muaj rau qhov tshwj xeeb: 320mm, 400mm, 630mm, 800mm, 1000mm thiab 1250mm. Qhov sib txawv ntawm ntsug thiab kab rov tav machining center worktables yog tias yav tas los muaj ib lub rooj plaub sab saum toj, thaum lub tom kawg muaj ib lub square lossis round rooj.
1) Lub worktable ntawm ntsug machining chaw feem ntau yog cov duab plaub vim nws tsis ua indexing txav. Lub workbench muaj T-shaped slots rau nruab workpieces lossis fixtures. Qhov nruab nrab T-shaped slots yog qhov siv T-shaped slots, thiab nws qhov tseeb yog siab dua li ob qhov T-shaped slots. Yog hais tias tus naj npawb ntawm T-puab zawj ntawm qhov chaw ua haujlwm yog tus lej khib, qhov nruab nrab T-shaped zawj yuav tsum yog qhov siv T-puab zawj; Yog tias nws yog tus lej sib npaug, T-puab zawj ze rau ntawm txoj kab nruab nrab ntawm qhov chaw ua haujlwm feem ntau yog xaiv raws li qhov siv groove.
2) Kab rov tav machining chaw worktables feem ntau yog tsim nyob rau hauv ib tug square los yog voj voog vim indexing los yog rotary motion. Standard workbench saum yog nruab nrog T-shaped slots. Ntxiv nrog rau kev siv qhov nruab nrab T-shaped slot ua tus qauv ntsuas, qee cov tuam txhab lag luam yuav ntxiv qhov kev txiav txim siab siab dua nyob rau hauv nruab nrab ntawm lub rooj zaum ua haujlwm raws li tus qauv ntsuas rau kev sib koom ua haujlwm thiab cov cuab yeej siv tshuab. Qee qhov kab rov tav machining chaw worktables tsis machined nrog T-shaped slots, tab sis nrog ntau zoo-txheej txheem ntsia hlau qhov thiab lub hauv paus txheem qhov. Cov ntsia hlau qhov no tiv thaiv los ntawm lub tes tsho ntsia hlau. Thaum txhim kho workpieces lossis fixtures, ua raws li cov lus qhia. Unscrew lub tes tsho sib txuas tsuas yog thaum tsim nyog.
2. Hom qauv ntawm workbench Cheebtsam
1) Cov khoom ua haujlwm ntawm lub chaw ua haujlwm me me suav nrog lub rooj zaum ua haujlwm, lub eeb uas txhawb nqa lub rooj zaum ua haujlwm, lub pob ntsia hlau, lub zog txo qis, servo motors thiab kev taw qhia rail guards, thiab lwm yam. iav, thiab servo lub cev muaj zog thiab cov ntsia hlau txuas ncaj qha los ntawm kev sib txuas.
2) Cov qauv ntawm lub workbench Cheebtsam ntawm kab rov tav machining chaw yog ntau complex tshaj li ntawm ntsug machining chaw. Ntxiv nrog rau cov zawv zawg zawv zawg, pob ntsia hlau, txuas txuas, servo lub cev muaj zog thiab cov lus qhia kev tsheb nqaj hlau uas txhawb nqa lub rooj zaum ua haujlwm, nws yuav tsum tau ntxiv Ib txheej ntawm cov txheej txheem indexing los yog cov txheej txheem teb. Feem ntau pom yog ob qhov indexing worktable qauv uas siv nas toothed discs rau qhov chaw. Lub toothed disc nce thaum lub sij hawm indexing, thiab ntog thaum indexing xaus. Lub hydraulic lub tog raj kheej clamps lub indexing worktable, thiab qhov indexing raug tuaj yeem ncav cuag ± (2 "~ 3"). Daim duab 2-25 qhia txog cov qauv ntawm CNC indexing rooj. CNC worktables yuav siv tau rau angular machining los yog nruam rotational txiav uas tsis tuaj yeem ua tiav los ntawm indexing worktables.
