Mawonekedwe a chodula mphero

Odula mpherozimabwera m'mawonekedwe angapo ndi makulidwe ambiri. Palinso kusankha kwa zokutira, komanso kangaude ngodya ndi chiwerengero cha kudula pamalo.

• Mawonekedwe:Maonekedwe angapo muyezo wawodula mpheroamagwiritsidwa ntchito m'makampani masiku ano, omwe akufotokozedwa mwatsatanetsatane pansipa.
• Zitoliro / mano:Zitoliro za mpheroyo ndi mizere yakuya ya helical yomwe imathamangira chodulira, pomwe mpeni wakuthwa m'mphepete mwa chitolirocho umadziwika kuti dzino. Dzino limadula zinthu, ndipo tchipisi tazinthu izi zimakokedwa ndi chitoliro ndi kuzungulira kwa wodulayo. Pafupifupi nthawi zonse pamakhala dzino limodzi pa chitoliro chilichonse, koma ocheka ena amakhala ndi mano awiri pa chitoliro chilichonse. Nthawi zambiri, mawuchitolirondidzinoamagwiritsidwa ntchito mosiyanasiyana. Odula mphero amatha kukhala ndi mano amodzi mpaka ambiri, awiri, atatu ndi anayi omwe amapezeka kwambiri. Nthawi zambiri, wodulayo akakhala ndi mano ambiri, m'pamenenso amatha kuchotsa zinthu mwachangu. Choncho, a4-odula manoakhoza kuchotsa zinthu pawiri mlingo wa awodula mano awiri.
• Helix angle:Zitoliro za chodulira mphero pafupifupi nthawi zonse zimakhala zozungulira. Ngati zitolirozo zinali zowongoka, dzino lonselo likhoza kukhudza zinthuzo nthawi imodzi, kuchititsa kunjenjemera ndi kuchepetsa kulondola ndi kukongola kwa pamwamba. Kuyika zitoliro pamakona kumalola dzino kuti lilowe muzinthu pang'onopang'ono, kuchepetsa kugwedezeka. Nthawi zambiri, odula omaliza amakhala ndi ngodya yapamwamba (yolimba helix) kuti athe kumaliza bwino.
• Kudula pakati:Ena odula mphero amatha kubowola molunjika pansi (kudumphira) kudzera muzinthuzo, pamene ena sangathe. Izi zili choncho chifukwa mano a ocheka ena sapita mpaka pakati pa nkhope yomaliza. Komabe, ochekawa amatha kudula pansi pakona ya madigiri 45 kapena kupitirira apo.
• Kuphatikiza kapena kumaliza:Mitundu yosiyanasiyana yodulira imapezeka podula zinthu zambiri, kusiya kutsika kosawoneka bwino (kovuta), kapena kuchotsa zinthu zocheperako, koma kusiya kutha bwino (kumaliza).Wocheka wowawaakhoza kukhala ndi mano opindika pothyola tinthu tating'onoting'ono. Manowa amasiya malo okhwima kumbuyo. Wodula womaliza akhoza kukhala ndi mano ambiri (anayi kapena kuposerapo) pochotsa zinthu mosamala. Komabe, kuchuluka kwa zitoliro kumasiya malo ochepa kuti achotsedwe bwino, motero sizoyenera kuchotsa zinthu zambiri.
• Zopaka:Zida zoyenera zopaka zida zimatha kukhala ndi chikoka chachikulu pakudula ndikuwonjezera liwiro lodulira ndi moyo wa zida, ndikuwongolera kumapeto kwa pamwamba. Polycrystalline diamondi (PCD) ndi zokutira zolimba kwambiri zomwe zimagwiritsidwa ntchitoochekazomwe ziyenera kupirira kuvala kwapamwamba kwambiri. Chida chophimbidwa ndi PCD chikhoza kukhala chotalika nthawi 100 kuposa chida chosatsekedwa. Komabe, zokutira sizingagwiritsidwe ntchito pa kutentha pamwamba pa madigiri 600 C, kapena pazitsulo zachitsulo. Zida zopangira aluminiyamu nthawi zina zimapatsidwa zokutira za TiAlN. Aluminiyamu ndi chitsulo chomata kwambiri, ndipo chimatha kudziwotchera m'mano a zida, zomwe zimapangitsa kuti ziwoneke zosamveka. Komabe, sizimamatira ku TiAlN, kulola chidacho kuti chigwiritsidwe ntchito kwa nthawi yayitali mu aluminiyamu.
• Shank:Shank ndi gawo la cylindrical (lopanda chitoliro) la chida chomwe chimagwiritsidwa ntchito kuti chigwire ndikuchiyika mu chotengera. Shank ikhoza kukhala yozungulira bwino, ndipo imagwiridwa ndi mikangano, kapena ikhoza kukhala ndi Weldon Flat, pomwe chopukutira, chomwe chimadziwikanso kuti grub screw, chimalumikizana ndi torque yowonjezereka popanda chida kutsetsereka. Kutalika kwa shank kumatha kukhala kosiyana ndi kukula kwa gawo lodulira la chida, kotero kuti chitha kugwiridwa ndi chogwirizira chokhazikika. diameter) yotchedwa "stub", yaitali (5x diameter), yaitali (8x diameter) ndi yowonjezera yowonjezera (12x diameter).
