Titanium alloy TC4 machining zais cia

I. Kev Taw Qhia
Titanium alloy yog dav siv hauv aerospace, kev kho mob thiab lwm yam kev lag luam rau nws cov kev ua tau zoo heev. Txawm li cas los xij, titanium alloys nyuaj rau tshuab, tshwj xeeb tshaj yog thaum machining nyias-walled kab noj hniav, ntsib cov teeb meem xws li kev sib tham thiab deformation. Nyob rau hauv daim ntawv no, peb yuav coj ib feem ntawm titanium alloy TC4 cov ntaub ntawv nrog 2 hli nyias-walled kab noj hniav ua piv txwv los tham txog nws cov machining nyuaj thiab hais txog cov kev daws teeb meem.
Thib ob, titanium alloy nyias-walled kab noj hniav seem tsom xam
Titanium alloy nyias-walled kab noj hniav npog qhov chaw muaj cov yam ntxwv nram qab no: tag nrho cov tsos ntawm ib tug loj arc nto nyias-walled kab noj hniav kab noj hniav, arc nto kab noj hniav phab ntsa thickness ntawm 2 hli, ob kawg ntawm lub sib txuas lub xub pwg thickness ntawm 6 hli. txhawm rau xyuas kom meej tias lub sealing ntawm lub npog phaj thiab lub thawv tom qab kev teeb tsa, qhov yuav tsum tau ua ntawm lub npog phaj qhov chaw mounting nto flatness ntawm 0.1mm.
Thib peb, kev soj ntsuam thev naus laus zis

1. Kev ua haujlwm nyuaj:
◆ Cov teeb meem sib tham: Vim lub hardness siab thiab tsis zoo thermal conductivity ntawm titanium alloy khoom, chattering yog ib qho yooj yim tshwm sim thaum lub sij hawm machining txheej txheem, cuam tshuam qhov machining raug thiab nto zoo.
◆ teeb meem Deformation: nyias-walled qauv yog ib qho yooj yim deformed thaum lub sij hawm machining, uas yuav tsum tau zam los ntawm kev siv cov txheej txheem machining tsim nyog thiab cov cuab yeej tsim.
2. Machining cov kauj ruam:
◆ Convex kab noj hniav ntxhib milling, tiav milling thiab mounting qhov machining: ua ntej, txheej txheem sab nraud qhov ntev ntawm lub npog qhov chaw kom ntseeg tau tias qhov roughness ntawm qhov chaw ua tau raws li qhov yuav tsum tau ua, thiab ua lub qhov mounting.
◆ Concave kab noj hniav ntxhib thiab ua tiav milling ua tiav: siv cov cuab yeej ua haujlwm kom paub meej qhov chaw, txais yuav txoj kev khawb qhov zawj rau kev ua haujlwm ntxhib, thiab tom qab ntawd ua tiav machining.
◆ Tiav machining ntawm mounting nto: xyuas kom meej qhov flatness thiab nto zoo ntawm mounting nto los ntawm xov milling, zoo sib tsoo thiab lapping thiab lwm yam machining txoj kev.
Plaub, kev siv thev naus laus zis thiab kev tsim cov cuab yeej siv
1. Convex kab noj hniav machining:
◆ Xaiv plaub-flute kawg zeb nrog cov ntsiab lus cobalt siab rau kev ua haujlwm ntxhib, khaws cov kua dej txaus kom ntev lub cuab yeej.
◆ Siv polycrystalline cubic boron nitride pob kawg milling cutter kom tiav, txais yuav streamline nto tiav txoj kev, thiab tswj qhov yuam kev nyob rau hauv 0.012mm.
2. Concave kab noj hniav machining:
◆ Siv workpiece kom paub meej qhov chaw ntawm lub hau npog thiab workpiece kom tsis txhob chattering thiab deformation.
◆ Kev kho tsis ua haujlwm ntuj yuav tsum tau ua tom qab siv lub tshuab ntxhib los tso cov kev ntxhov siab sab hauv thiab tiv thaiv machining deformation.
◆ Nws yog ib qho tsim nyog yuav tsum tau hloov lub mating nto ntawm lub hau npog thiab workpiece ob peb zaug thaum lub sij hawm ua tiav machining kom paub tseeb tias qhov chaw raug.
3. Mounting nto finishing:
◆ Xaiv qhov chaw tsim nyog siv thiab mounting kho qhov chaw, ua ntej ua tiav kev ua tiav milling, tom qab ntawd ua tiav kev sib tsoo thiab lapping ua tiav.
◆ Kev tshuaj xyuas tas li yuav tsum tau ua nyob rau hauv cov txheej txheem kom ntseeg tau tias qhov flatness thiab nto zoo raws li qhov yuav tsum tau ua.
V. Xaus
Los ntawm kev tshuaj xyuas thiab xyaum ua cov txheej txheem machining ntawm titanium alloy TC4 cov khoom, 2 hli nyias-walled kab noj hniav npog qhov chaw, peb tau ua tiav cov teeb meem machining xws li chattering thiab deformation. Tsim nyog machining txheej txheem thiab cuab yeej tsim yog ib qho tseem ceeb los xyuas kom meej machining raug thiab nto zoo. Hauv kev ua haujlwm tiag tiag, peb yuav tsum siv tag nrho lub luag haujlwm ntawm cov cuab yeej los txo cov nqi, ua haujlwm yooj yim, txuag sijhawm thiab ua haujlwm siab.
