Xaiv Txoj Cai Rotary Table
Xaiv qhov zoo CNC rotary rooj yuav tsum sib piv lub rooj lub peev xwm rau cov khoom tshwj xeeb thiab cov txheej txheem, tsis yog tsuas yog yuav lub rooj loj tshaj plaws lossis kim tshaj plaws. Thawj lo lus nug yog hom kev ua hauj lwm lub rooj yuav ua li cas: ntshiab indexing (rotating rau tsau cov ces kaum thiab ces clamping rau txiav) yuav tsum tau ib tug nruj, yog lub rooj nrog ib tug muaj zog clamp, tab sis siab rotational ceev thiab dynamic teb tsis tseem ceeb - ib tug zoo worm iav rooj yog zoo tagnrho thiab tus nqi - zoo. Ib txhij contouring (rotating thaum txiav, tshwj xeeb tshaj yog rau 3D nto) yuav tsum tau du, backlash -dawb suab, siab dynamic teb, thiab raug txoj hauj lwm tawm tswv yim - ib tug ncaj- lub rooj tsav tsheb feem ntau yog txoj cai xaiv, los yog ib tug siab -precision preloaded cab iav rooj rau tsawg demanding contouring. Lo lus nug thib ob yog axis suav: puas yuav 4 axis tuav cov khoom, lossis puas yog 5-axis muaj peev xwm xav tau? Ntau lub khw tshaj -yuav tsib-axis muaj peev xwm thaum lub 4th axis yuav lis 80% ntawm lawv cov hauj lwm ntawm ib nrab tus nqi, thaum lwm tus nyob rau hauv-yuav thiab tom qab ntawd pom lawv tus kheej tsis tuaj yeem ua haujlwm 3D nyuaj - qhov kev txiav txim siab yuav tsum yog raws li qhov sib xyaw ua ke, tsis yog nyob rau yav tom ntej speculation.
Qhov loj thiab lub peev xwm thauj khoom yuav tsum tau muab sib xyaw rau qhov loj tshaj plaws workpiece thiab fixture lub rooj yuav nqa, nrog ib tug 20-30% kev nyab xeeb margin rau dynamic loads thaum lub sij hawm acceleration. Cov kab lus kab yuav tsum haum rau qhov chaw thiab qhov khoom siv tsis tas yuav overhanging ntau dhau, thiab qhov siab nruab nrab yuav tsum haum rau hauv lub tshuab Z-axis mus ncig nrog lub cuab yeej siv ntev tshaj plaws. Qhov yuav tsum tau ua kom raug yuav tsum tau tsav los ntawm qhov nruj tshaj plaws angular kam rau ua ntawm qhov chaw, nrog rau lub rooj qhov tseeb tsawg kawg yog 3-5 npaug zoo dua qhov kam rau ua (tus qauv ntsuas ntsuas). Kev tswj hwm kev sib raug zoo yuav tsum raug txheeb xyuas ua ntej yuav khoom: lub rooj yuav tsum tau txais kev txhawb nqa los ntawm lub tshuab CNC tswj, nrog rau qhov tseeb axis tsav, lub teeb liab tawm tswv yim, thiab M-code functions rau clamp/unclamp, thiab lub tshuab yuav tsum muaj ib tug muaj axis tsav thiab txaus nco thiab saib - ua ntej muaj peev xwm rau ib txhij multi{10}}axis cov kev pab cuam. Kev txiav txim siab txog kev teeb tsa - cable tswj, kev tiv thaiv coolant, nti khiav tawm, thiab seb lub rooj yuav txuas mus tas li lossis txav ntawm cov tshuab - kuj cuam tshuam rau kev xaiv. Thaum kawg, tom qab- kev txhawb nqa muag, muaj cov khoom seem, cov kev pabcuam calibration, thiab cov chaw tsim khoom lub koob npe nrov rau kev ua tau zoo thiab kav ntev yuav tsum hnyav hnyav, vim hais tias lub rooj rotary yog ib qho cuab yeej precision uas yuav xav tau kev saib xyuas ib ntus thiab rov kho dua nws lub neej kev pabcuam.
Xaus
CNC rotary rooj yog ntau tshaj li ib qho yooj yim accessory uas spin ib workpiece - nws yog cov khoom uas hloov ib tug peb -axis tshuab los ntawm ib tug txwv, ib tug -lub ntsej muag machining platform rau hauv ib tug saj zawg zog multi-axis manufacturing system muaj peev xwm ua complex, siab - precision qhov chaw nyob rau hauv ib tug yooj yim teeb. Los ntawm kev ntxiv cov axis tswj kev sib hloov, nws tshem tawm qhov yuam kev ntawm kev rov ua dua - kho, khaws cov duab geometric raug ntawm cov yam ntxwv thoob plaws ntau lub ntsej muag, ua kom lub tshuab ua haujlwm ntawm 3D qhov chaw nyuaj thiab cov yam ntxwv helical uas yuav ua tsis tau lwm yam, thiab txo qis qhov tsis yog - sijhawm ua haujlwm. Txawm hais tias nws yog lub rooj iav cab uas muab cov khoom nruj, tus nqi - ua kom zoo indexing rau hnyav prismatic qhov chaw, ncaj qha -tsav torque lub rooj xa khoom arcsecond raug thiab siab -ceev ib txhij contouring rau aerospace thiab kev kho mob Cheebtsam, los yog ib tug tsib{{13}5 axis qhib lub rooj{13}axis ntawm lub tshuab uas twb muaj lawm, lub rooj teb yog ib qho ntawm qhov siab tshaj - rov qab nqis peev uas cov chaw tsim khoom tuaj yeem ua. Nws nce kev siv tshuab, txo cov neeg ua haujlwm thiab cov khoom seem, ua kom automation thiab teeb pom kev zoo - tawm ntau lawm, thiab nthuav dav ntau yam kev ua haujlwm hauv lub khw tuaj yeem tau txais txiaj ntsig zoo. Rau txhua lub khw tab tom nrhiav kom txav mus dhau qhov yooj yim peb -axis machining, txhim kho qhov raug thiab sib xws, thiab sib tw rau ntau dua thiab siab dua -tus nqi ua haujlwm, ntxiv qhov zoo CNC rotary rooj feem ntau yog ib qho kev hloov kho muaj txiaj ntsig tshaj plaws.
