Kuti mudule mwachangu komanso molimba kwambiri, gwiritsani ntchito mphero zazifupi zokhala ndi mainchesi akulu
Mitundu yosinthika ya helix kumapeto imachepetsa macheza ndi kugwedezeka
Gwiritsani ntchito cobalt, PM/Plus ndi carbide pazinthu zolimba komanso ntchito zopanga kwambiri
Ikani zokutira pazakudya zapamwamba, kuthamanga ndi moyo wa zida
Mitundu Yotsiriza:
Mapeyala a square endamagwiritsidwa ntchito ngati mphero wamba kuphatikiza slotting, profiling ndi kudulira.
Keyway mapeto mpheroamapangidwa ndi ma diameter ang'onoang'ono odula kuti apange zolimba pakati pa keyway slot yomwe amadula ndi kiyi ya woodruff kapena keystock.
Mipira yomaliza,Amatchedwanso mpira mphuno mapeto mphero, ntchito mphero contoured pamalo, slotting ndi pocketing.Mphero yomaliza ya mpira imapangidwa ndi m'mphepete mwake ndipo imagwiritsidwa ntchito popanga ma dies ndi nkhungu.
Zovuta zomaliza, omwe amadziwikanso kuti mphero za nkhumba, amagwiritsidwa ntchito kuchotsa mwamsanga zinthu zambiri panthawi yolemetsa.Mapangidwe a dzino amalola kuti asagwedezeke pang'ono, koma amasiya mapeto ovuta.
Mapeto a Corner radiuskukhala ndi m'mphepete mozungulira ndipo amagwiritsidwa ntchito pomwe utali wozungulira ukufunika.Mphero zapakona za chamfer zili ndi m'mphepete mwa ngodya ndipo zimagwiritsidwa ntchito pomwe kukula kwake sikofunikira.Mitundu yonse iwiriyi imapereka moyo wautali wa zida kuposa ma square end mphero.
Kumaliza ndi kumaliza mpheroamagwiritsidwa ntchito mumitundu yosiyanasiyana ya mphero.Amachotsa zinthu zolemetsa pamene akupereka mapeto osalala mu chiphaso chimodzi.
Pakona zozungulira mpheroamagwiritsidwa ntchito pogaya mphero zozungulira.Iwo ali ndi nsonga zodula pansi zomwe zimalimbitsa mapeto a chida ndi kuchepetsa kupukuta m'mphepete.
Mabowola mpherondi zida zamitundumitundu zomwe zimagwiritsidwa ntchito poyang'ana, kubowola, kuwerengera, kupukuta ndi ntchito zosiyanasiyana zamphero.
Mapeto a taperedamapangidwa ndi m'mphepete mwake omwe amawombera kumapeto.Amagwiritsidwa ntchito mumitundu ingapo yakufa komanso nkhungu.
Mitundu ya Chitoliro:
Zitoliro zimakhala ndi zigwa kapena zigwa zomwe zimadulidwa mu thupi la chidacho.Kuchuluka kwa zitoliro kumawonjezera mphamvu ya chida ndikuchepetsa malo kapena kuyenda kwa chip.Mapeto otsiriza okhala ndi zitoliro zochepa pamphepete adzakhala ndi malo ambiri a chip, pamene mphero zokhala ndi zitoliro zambiri zidzagwiritsidwa ntchito pazinthu zodula kwambiri.
Chitoliro Chokhamapangidwe amagwiritsidwa ntchito pa makina othamanga kwambiri komanso kuchotsa zinthu zambiri.
Zitoliro Zinayi/Zambirimapangidwe amalola kuti chakudya chikhale chofulumira, koma chifukwa cha kuchepa kwa chitoliro, kuchotsa chip kungakhale vuto.Amapanga mapeto abwino kwambiri kuposa zida ziwiri ndi zitatu za zitoliro.Oyenera mphero zotumphukira ndi zomaliza.
Zitoliro Awirimapangidwe ali ndi kuchuluka kwa malo a chitoliro.Amalola kuti chip chinyamule kwambiri ndipo amagwiritsidwa ntchito makamaka polowetsa ndi kuyika m'thumba zinthu zopanda ferrous.
Zitoliro Zitatumapangidwe ali ndi danga lofanana la chitoliro ngati zitoliro ziwiri, komanso amakhala ndi gawo lalikulu lamphamvu lamphamvu.Amagwiritsidwa ntchito poponyera m'thumba ndi slotting zinthu zachitsulo komanso zopanda ferrous.
Zida Zodulira:
Chitsulo Chothamanga Kwambiri (HSS)imapereka kukana kwabwino kwa kuvala ndipo imawononga ndalama zochepa kuposa cobalt kapena carbide end mphero.HSS imagwiritsidwa ntchito pogaya zinthu zonse zachitsulo komanso zopanda ferrous.
Vanadium High Speed Steel (HSSE)amapangidwa ndi chitsulo chothamanga kwambiri, kaboni, vanadium carbide ndi ma alloys ena opangidwa kuti awonjezere kukana kwa abrasive kuvala komanso kulimba.Amagwiritsidwa ntchito kwambiri pazitsulo zosapanga dzimbiri komanso ma aluminium apamwamba a silicon.
Kobalt (M-42: 8% Cobalt):Amapereka kukana kovala bwino, kuuma kotentha kwambiri komanso kulimba kuposa chitsulo chothamanga kwambiri (HSS).Pali kuchepa pang'ono kapena kutsika kwapang'onopang'ono pansi pamikhalidwe yodula kwambiri, kulola chidacho kuthamanga 10% mwachangu kuposa HSS, zomwe zimapangitsa kuti pakhale mitengo yabwino kwambiri yochotsa zitsulo ndikumaliza bwino.Ndi zotsika mtengo zinthu zabwino Machining kuponyedwa chitsulo, zitsulo ndi titaniyamu aloyi.
Chitsulo chaufa (PM)ndizovuta komanso zotsika mtengo kuposa carbide yolimba.Ndilolimba komanso silimakonda kusweka.PM imagwira ntchito bwino muzinthu <30RC ndipo imagwiritsidwa ntchito pazowopsa kwambiri komanso zochulukira monga roughing.
Carbide yolimbaimapereka kukhazikika bwino kuposa chitsulo chothamanga kwambiri (HSS).Ndiwopanda kutentha kwambiri ndipo amagwiritsidwa ntchito pa liwiro lalikulu pazitsulo zotayidwa, zinthu zopanda ferrous, mapulasitiki ndi zida zina zolimba kumakina.Carbide mapeto mphero amapereka kukhazikika bwino ndipo akhoza kuthamanga 2-3X mofulumira kuposa HSS.Komabe, mitengo yolemetsa ndiyoyenera kwambiri pazida za HSS ndi cobalt.
Carbide - Malangizoamamangidwa mpaka kumapeto kwa zida zachitsulo.Amadula mofulumira kuposa chitsulo chothamanga kwambiri ndipo amagwiritsidwa ntchito kwambiri pazinthu zachitsulo komanso zopanda chitsulo kuphatikizapo zitsulo zotayidwa, zitsulo ndi zitsulo.Zida zokhala ndi nsonga za Carbide ndi njira yotsika mtengo pazida zazikulu zokulirapo.
Polycrystalline Diamondi (PCD)ndi dayamondi yopangidwa yodabwitsa komanso yosamva kuvala yomwe imalola kudula mwachangu pazinthu zopanda ferrous, mapulasitiki, ndi ma aloyi ovuta kwambiri ku makina.
Zovala Zokhazikika / Zomaliza:
Titanium Nitride (TiN)ndi ❖ kuyanika kwanthawi zonse komwe kumapereka mafuta ambiri komanso kumawonjezera kutuluka kwa chip muzinthu zofewa.Kutentha ndi kuuma kukana kumapangitsa chida kuti chiziyenda pa liwiro lapamwamba la 25% mpaka 30% mu liwiro la machining vs.
Titanium Carbonitride (TiCN)Ndiwolimba komanso wosamva kuvala kuposa Titanium Nitride (TiN).Amagwiritsidwa ntchito kwambiri pazitsulo zosapanga dzimbiri, zitsulo zotayidwa ndi aluminiyamu.TiCN ikhoza kukupatsani mwayi woyendetsa mapulogalamu pa liwiro lalikulu la spindle.Samalani pazinthu zopanda ferrous chifukwa cha chizolowezi cha ndulu.Pamafunika chiwonjezeko cha 75-100% machining liwiro vs. unncoated zida.
Titanium Aluminium Nitride (TiAlN)ali ndi kuuma kwakukulu ndi kutentha kwa okosijeni poyerekeza ndi Titanium Nitride (TiN) ndi Titanium Carbonitride (TiCN).Zoyenera zitsulo zosapanga dzimbiri, zitsulo za carbon alloy high, nickel-based high-temperature alloys ndi titaniyamu.Samalani muzinthu zopanda ferrous chifukwa cha chizolowezi cha ndulu.Pamafunika chiwonjezeko cha 75% mpaka 100% pa liwiro la makina motsutsana ndi zida zosatsekedwa.
Aluminium Titanium Nitride (AlTiN)ndi imodzi mwa zokutira zolimba komanso zolimba kwambiri.Amagwiritsidwa ntchito popanga ndege ndi zinthu zakuthambo, aloyi ya faifi tambala, chitsulo chosapanga dzimbiri, titaniyamu, chitsulo choponyedwa ndi chitsulo cha carbon.
Zirconium Nitride (ZrN)ndi ofanana ndi Titanium Nitride (TiN), koma ali ndi kutentha kwa okosijeni kwapamwamba ndipo amakana kumamatira ndikulepheretsa kumanga m'mphepete.Amagwiritsidwa ntchito kwambiri pazinthu zopanda chitsulo kuphatikiza aluminium, mkuwa, mkuwa ndi titaniyamu.
Zida zosavalamusamawonetsere chithandizo chamankhwala pamlingo wocheperako.Amagwiritsidwa ntchito pa liwiro lochepetsedwa kuti agwiritsidwe ntchito pazitsulo zopanda chitsulo.
