Zambiri zamalonda
The Precision Matthews Mill, ya omwe amaphunzitsidwa pa Rong Fu Mill
Ngati mwatenga kalasi ya Manual Mill pogwiritsa ntchito Rong Fu Mill, ndiye kuti zonse zomwe muyenera kuchita kuti mugwiritse ntchito mphero yatsopano ya Precision Matthews ndikuwerenga chikalatachi kapena muwone kanema yomwe ikubwera. Afotokoza mwachidule kusiyana kwakukulu pakati pa mphero ya Precision Matthews ndi mphero ya Rong Fu yomwe mudaphunzitsidwa. (Kuyambira pano, izi zikhoza kutchulidwa ndi oyambirira awo, PM ndi RF.) Kwa mbali zambiri, mudzapeza kugwiritsa ntchito mphero ya Precision Matthews kukhala yowonjezera mwachilengedwe yogwiritsira ntchito mphero ya Rong Fu. Ndilolimba komanso lamphamvu kwambiri ndi tebulo lalikulu, koma kugwiritsa ntchito ndilofanana. Monga Rong Fu, makina a PM amakhala ndi zida zogwiritsira ntchito R8 collet, kuti athe kugawana zida zomwezo.
Monga Rong Fu, tidzasunga tebulo la Precision Matthew pamene silikugwiritsidwa ntchito.
Kuti mugwiritse ntchito mpheroyo, muyenera kuyatsa zida zowonjezerazi poyatsa mpheroyo, yomwe ili kumanzere kwa thupi lalikulu. Izi zipereka mphamvu ku ma motors atatu opangira ma auto-feed, DRO (malo owerengera), kuwala kozungulira, ndi mpope woziziritsa zomwe zidzayikidwe pambuyo pake. (Motor palokha ilibe master switch ndipo imakhala yokonzeka kuyatsa nthawi zonse.)
Kusiyana kwakukulu ndikuti PM ndi mphero ya mawondo, pamene Rong Fu ndi mphero ya mapewa. Pa Rong Fu, kulondola mu z-axis kumachokera ku quill. Pa PM, quill ili ndi zolembera zocheperako, popanda kuwerenga zikwizikwi. Kulondola mu Z kumachokera kukweza ndi kutsitsa tebulo lonse.
Chogwirizira cha Z-axis ndi chachikulu kuposa chinacho chifukwa mumafunika torque yambiri kuti mukweze tebulo osati kungoyigwedeza. Chogwiririracho chili ndi magawo awiri, opangidwa mopepuka ndi kasupe; Izi ndichifukwa choti chakudya chamagalimoto chisazungulire chogwirira chachikulu chozungulira. Kuti mukweze ndi kutsitsa tebulo pamanja, gwirizanitsani zogwirira ntchito ndikukankhira chogwiriracho mkati. Muyenera kukakamiza chogwirira kuti chikhale chogwira pochitembenuza. Ngati muli ndi vuto kuti mugwirizane, ndiye kuti mukukankhira pang'ono molunjika. Apa muli ndi zikwizikwi za inchi zolondola, pogwiritsa ntchito kuyimba kwa analogi kapena mwina DRO.
Ntchito zoyambira za DRO ndizofanana ndi za Rong Fu; ili ndi mawerengedwe atatu a axis kuposa awiri. Ngati DRO ikuwoneka kuti ikuvomereza kusindikiza, yesani kugunda batani la Chotsani (C) ndikuyesanso. (Monga Rong Fu's DRO, ili ndi ntchito zina zaudongo zomwe sindinavutikepo kuziphunzira. Yang'anani pa intaneti ngati mukufuna kudziwa zambiri.)
Rong Fu ili ndi chakudya chamagalimoto pamodzi ndi X; Precision Matthews ali ndi auto feeds motsatira X, Y, ndi Z. Zonsezi zimagwira ntchito mofanana ndi X-feed pa Rong Fu: sunthani lever kuti iyambe kuyenda (Ndalemba mayendedwe), tembenuzirani knob kuti musinthe liwiro, lomwe lingathe kupita mpaka zero, kapena gwirani batani kuti muyambe kuyenda mofulumira. (Izi zilinso ndi switch yozimitsa, yomwe iyenera kusiyidwa. Batani lofulumira limayatsidwa mphamvu ikayatsidwa.)
Monga chakudya cha Rong Fu, izi zimakhala ndi zoyimitsa mbali zonse ziwiri. Komabe, mosiyana ndi Rong Fu, awa siwovuta kuyimitsa patebulo. Mutha kupita patsogolo pang'ono pogwiritsa ntchito zogwirira ntchito, koma izi ziyenera kupewedwa. Choncho, chisamaliro chiyenera kutengedwa pogwiritsa ntchito chakudya chamanja pafupi ndi malire a tebulo. Makamaka, musakweze tebulo kupyola malo akumtunda a Z feed auto-stop point - kutero kutha kupindika njira yolondolera kuyimitsidwa! (Ndizochepa pang'ono; titha kuzikweza posachedwa.) Kuyimitsa uku kwakhazikitsidwa kotero kuti palibe kuthekera kobweretsa chopondera patebulo. (Izi sizingakulepheretseni kuyendetsa spindle mu chidutswa chanu, kuyendetsa chida chanu patebulo, ndi zina). Koma izi zikutanthauza kuti simungathe kufika pachidutswa chanu ngati mukupalasa pafupi ndi tebulo. Apanso, musakweze tebulo pamwamba kuposa mfundo iyi; m'malo mwake, tsegulani ndikutsitsa quill kuti mubweretse chida chanu pachidutswacho. Njira yoyenera ngati mukugwira ntchito pafupi ndi tebulo lomwe lili pamwamba pa tebulo: kwezani tebulo pogwiritsa ntchito Z auto-feed mpaka kuyimitsidwa kwamoto kuyambika. Kenaka tsitsani quill pansi kuti chidacho chikhale pansi pa kuya kwakuya chomwe chiyenera kufika. Kenako tsekani quill ndi kutsitsa tebulo. Pangani zosintha zonse za Z pogwiritsa ntchito tebulo kuyambira pamenepo.
Mutha kukweza ndi kutsitsa quill ngati makina osindikizira, ndi chogwirira ichi. Monga makina osindikizira, ndipo mosiyana ndi Rong Fu, ili ndi kasupe yemwe amachotsa nthawi iliyonse isanatseke. Nthawi zambiri, izi muzigwiritsa ntchito pobowola. Mudzafuna kuti ikhale yokhoma pamalo amodzi pochita mphero, chifukwa kuyisuntha kumalepheretsa ma Z omwe akuwonetsedwa mu DRO.
Njira zomwe zikuwonetsedwa pansipa ndi quill auto-feed. Ndizinthu zapamwamba zomwe sitikuphimba pano. Kugwiritsa ntchito sikuloledwa popanda malangizo ena. Ndizothandiza makamaka ngati muli ndi mabowo ambiri obwerezabwereza kuti mubowole. Lumikizanani ndi Ethan Moore, mphunzitsi wa kalasi ya mphero, mwachindunji kuti mudziwe zambiri ngati mukuwona kuti mungafunike kugwiritsa ntchito izi.
Kusintha Chida
Pamwamba kumanzere kwa mutu pali chotchingira chopota; kwezani kapena kutsitsa pang'ono kuti muchite. Koma mwina simugwiritsa ntchito izi pafupipafupi. Ngati PM ali ndi kolala yamanja ngati Rong Fu, mukadagwiritsa ntchito kuti spindle ikhale pamalo pomwe mukumangitsa makola. Koma ndizosafunikira chifukwa PM ali ndi chosinthira cha pneumatic automatic.
Kuti mugwiritse ntchito, muyenera kuwonetsetsa kuti quill ndi yotsekedwa kwathunthu. Ikani collet ndi chida chomwe chili mmenemo, kugwirizanitsa kagawo pa collet kotero kuti imayendayenda kwambiri. Musapitilize kukanikiza batani kupitirira pamenepo. Kuti muchotse koleti, ingodinani batani la OUT mpaka collet itamasulidwa. Izi zitenga nthawi yayitali. Dongosolo lonse ndi losavuta komanso lachangu. Mukayamba kuyika chida chokhala ndi quill osakhazikika kapena osatsekedwa, zinthu zitha kusuntha ndikukhala wopambana. Ngati ndi choncho, ingoyimani, kwezani ndi kutseka cholemberacho, ndi kuyesanso.
Pazida zina, mutha kuyika chala chanu pakati pa chida ndi collet. Sindikudziwa zomwe zingachitike mutakanikiza batani la IN. Sindikufuna kudziwa, ndipo ndikupangira kuti inunso musatero. Ingogwirani chirichonse kuchokera pansi.
Kusintha kwa zida kumafuna mpweya wa shopu kuti ugwire ntchito. Palibe njira ina yamanja ngati mulibe mpweya. Kuthamanga kwa olamulira kumayikidwa pa 90 psi ndipo sikuyenera kusinthidwa.
Kuthamanga Mgayo
Kuti muyambitse mphero, ingotembenuzani ndodo yamagetsi kuti muthamangitse spindle patsogolo (FWD) kapena mmbuyo (REV). Chodabwitsa chimodzi chofunikira: mayendedwe ozungulira omwe akuwonetsedwa amangogwira zida zapamwamba. Ngati mphero yasinthidwa kukhala zida zotsika (monga momwe tafotokozera m'munsimu), mayendedwe amatembenuzidwa; Zikatero, muyenera kutembenuza buno kuti REV kuyendetsa spindle patsogolo. Palibe master power switch kuti muthandizire; makina opangira mphero amakhala okonzeka kupita. Pakali pano palibe kuyimitsidwa mwadzidzidzi (ngakhale ndikukonzekera kuwonjezera imodzi).
Liwiro Lagalimoto
Chigayo cha Rong Fu chili ndi ma liwiro asanu ndi limodzi okha. The Precision Matthews ili ndi maulendo awiri osakanikirana; mkati mwamtundu uliwonse, mutha kusintha liwiro la spindle mosalekeza. Kuti tigwiritse ntchito, nthawi zonse tidzafuna kukhala mumtundu wa zida za HI, monga zikuwonekera.
Mutha kusintha makonzedwe a giya pamene injini yayimitsidwa.
Kuti musinthe ku gulu la zida za LO, kanikizani chotchinga mkati pang'ono, kenaka mutembenuzire lever kumbuyo. Tulutsani mphamvu yamkati ndipo pitirizani kutembenuzira lever mpaka chotsekereza chowoneka bwino chifikire. Kumbukirani kuti mayendedwe a spindle amasinthidwa mukamagwiritsa ntchito magiya apansi. Kuti mubwerere ku zida za HI, chitani zomwezo mobweza.
Malo aliwonse a lever pakati pa ma detens awiriwa salowerera ndale, zomwe zimakhala zothandiza ngati mukufuna kuti spindle iyende momasuka. (Pa Rong Fu, mukhoza kutembenuza ndodoyo ili mu giya; simungatero pano.) Ngati mumavutika kuti mulowetse chopingacho kuti chikhale giya chifukwa cha zinthu zopanda ndale, mungafunikire kutembenuza ntchentcheyo pang'ono kuti magiya agwirizane.
Pakati pa zida zilizonse, mutha kusankha kuchokera pa liwiro lopitilira, 70 - 500 rpm mumagetsi otsika ndi 600 - 4200 rpm pamagetsi apamwamba. Ntchito zathu zochepa zimafuna kuthamanga kwa spindle zosakwana 600 rpm, ndichifukwa chake makinawa amagwiritsidwa ntchito nthawi zambiri pamagiya apamwamba.
Mutha kusintha liwiro potembenuza gudumu kumtunda kumanja kwa mutu. Ndikofunikira kwambiri kuti mungosintha izi pomwe mota ikuyenda!
Mutha kuwerengera liwiro lokhazikika pawindo loyenera kuyika zida zamakono. Pachithunzichi, spindle idzatembenuka pafupifupi 800 rpm (chifukwa makina ali mu gear yapamwamba, monga mwachizolowezi).
Precision Matthews ndi yolimba kwambiri komanso yamphamvu kuposa Rong Fu, kotero mutha kugwiritsa ntchito liwiro pafupifupi 1.5 mpaka 2 mwachangu momwe mungagwiritsire ntchito pa Rong Fu. Padzakhala tchati cha liwiro loperekedwa pamakina. Izi ndi malangizo okhawo omwe ndikhoza kusintha pakapita nthawi. (Zolemba zam'mbali zokhudzana ndi Rong Fu: kuthamanga komwe ndaphunzitsa podula aluminiyamu mwina kwakhala kodziletsa; Ndayikanso tchati chowongolera chomwe chasinthidwa.)
Mfundo Zazikulu
Zingakhale zokopa kugwiritsa ntchito chododometsa panjira zakutsogolo za Y-axis kukhazikitsa zinthu. Kanizani chiyeso ichi. Osayika kalikonse pamenepo, ngakhale mwachidule! (Tidzawonjezera malo ogwirira ntchito pafupi posachedwa.)
Pali zingwe zambiri ndi mapaipi omwe amayenda mozungulira tebulo la makinawo. Izi sizingayendetsedwe mwamphamvu kwambiri, chifukwa ziyenera kukhala zaufulu kusuntha momwe zingafunikire kuti zifanane ndi kusuntha kwakukulu kwa tebulo. Yesetsani kudziwa mayendedwe awo ndikuwonetsetsa kuti sakugwira kapena kugwidwa pakati pa mbali zina pamene tebulo likuyenda.
Rong Fu ili ndi kusintha kumodzi, kupendekeka kwa mutu, komwe sikuyenera kusinthidwa popanda chilolezo kuchokera ku malo ogulitsa zitsulo. PM ndi yayikulunso m'gululi, ndi zosintha zinayi zoletsedwa: kupendekeka kwamutu, kugwedeza mutu, turret ram, ndi kuzungulira kwa turret. Zonsezi zimafuna chilolezo chifukwa makinawo amayenera kusinthidwa pambuyo pake. Chifukwa chake, muyenera kukhala ndi chosowa chachilendo kuti mulandire chilolezo ichi.
Tsekani:
Mukamaliza, yeretsani makinawo ndikubwezera zida zonse pamalo ake oyenera. Nthawi zambiri zimakhala bwino kusiya tebulo penapake pakati pamizere yopingasa (X ndi Y). Tebulo nthawi zambiri limasiyidwa lalitali, koma osayisiya molunjika pa Z stop yake yakumtunda. Onetsetsani kuti quill yatsekedwa pamalo ake apamwamba. Phimbani tebulo ndi nsalu ndikuzimitsa chingwe chamagetsi. Simuyenera kuchita chilichonse kuti mutseke mphamvu yayikulu kapena mzere wamphepo woponderezedwa.
Mfundo Zofunika Kuzikumbukira
Ndafotokozera kusiyana pakati pa makinawo bwinobwino, koma ngati mukusochera mwatsatanetsatane, kumbukirani makamaka zinthu izi:
- Ingosinthani liwiro la spindle pogwiritsa ntchito gudumu pomwe mota ikuyenda.
- Samalani pamene mukukweza tebulo pafupi ndi malo oima pamwamba.
- Kusuntha kwa Precision Z kumapangidwa ndikusuntha tebulo, osati quill.
- Chophimbacho chiyenera kukwezedwa bwino ndi kutsekedwa kuti mugwiritse ntchito chosinthira chida.
- Kuthamanga koyenera kwa zida ndi pafupifupi 1.5-2 kuthamanga komwe mungagwiritse ntchito pa Rong Fu.
