Ulwazi lweTungsten Carbide End Mills kunye neeMeko zayo ezinokuthi zingaphumeleli

Ngaba ii-end Mills zenziwe nge-carbide?

Uninzi lwezixhobo zokugqibela zenziwa ukusuka kwi-cobalt steel alloys - ebizwa ngokuba yi-HSS (i-Speed ​​​​Speed ​​Steel), okanye ukusuka kwi-tungsten carbide. Ukhetho lwemathiriyeli yesixhobo sakho sokusila esikhethiweyo siya kuxhomekeka kubunzima bomsebenzi wakho kunye nesantya esiphezulu sokusonta kumatshini wakho.

Yeyiphi eyona mill inzima?

Carbide end Mills.

I-Carbide end Mills yenye yezona zixhobo ezinzima zokusika ezikhoyo. Ecaleni kwedayimani zimbalwa kakhulu ezinye izinto ezilukhuni kune-carbide. Oku kwenza i-carbide ikwazi ukwenza i-machining phantse nayiphi na isinyithi ukuba yenziwe ngokuchanekileyo. I-Tungsten Carbide iwela phakathi kwe-8.5 kunye ne-9.0 kwisikali sobulukhuni buka-Moh, iyenza iphantse iqine njengedayimane.

Yintoni eyona nto ilungileyo yokusila yentsimbi?

Ngokukodwa, i-carbide end mills isebenza kakuhle kwintsimbi kunye ne-alloys yayo kuba ine-conductivity ephezulu ye-thermal kwaye isebenza kakuhle kwiintsimbi ezinzima. ICarbide ikwasebenza ngesantya esiphezulu, okuthetha ukuba umsiki wakho unokumelana namaqondo obushushu aphezulu kwaye unokuthintela ukuguga okugqithisileyo kunye nokukrazula. Xa ugqiba iinxalenye zensimbi ezingenasici, ukubalwa kweflute ephezulu kunye / okanye i-helix ephezulu iyadingeka kwiziphumo ezilungileyo. Ukugqiba i-mills yokugqiba insimbi engenasici iya kuba ne-helix angle phezu kwama-degrees angama-40, kunye nenani le-flute ye-5 okanye ngaphezulu. Ukufumana iindlela zokugqiba izixhobo ezinobundlobongela, ukubalwa kweflute kunokuqala ukusuka kwi-7 flutes ukuya phezulu njenge-14.

Yiyiphi eyona nto ingcono, i-HSS okanye i-carbide end Mills?

I-Solid Carbide ibonelela ngobungqongqo obungcono kunentsimbi yesantya esiphezulu (HSS). Iyamelana nobushushu ngokugqithisileyo kwaye isetyenziselwa usetyenziso lwesantya esiphezulu kwintsimbi ekhandiweyo, izinto ezingezizo, iiplastiki kunye nezinye izinto ezinzima ukuya kumatshini. Iintsimbi zokuphela kweCarbide zibonelela ngobungqongqo obungcono kwaye zinokuqhutywa nge-2-3X ngokukhawuleza kuneHSS.

Kutheni oomatshini bokugqibela bengaphumeleli?

1. Ukuyiqhuba ngokukhawuleza okanye ngokucotha kakhuluInokuchaphazela uBomi besixhobo.

Ukuqhuba isixhobo ngokukhawuleza kakhulu kunokubangela ubungakanani betshiphu enganeno kakhulu okanye ukusilela kwesixhobo esiyingozi. Ngokwahlukileyo, i-RPM ephantsi inokubangela ukuphambuka, ukugqiba kakubi, okanye ukunciphisa amaxabiso okususwa kwesinyithi.

2. Ukuyondla Kancinane Kakhulu okanye Kakhulu.

Omnye umba obalulekileyo wezantya kunye nokutya, elona nqanaba lokutya elingcono lomsebenzi liyahluka kakhulu ngohlobo lwesixhobo kunye nesixhobo somsebenzi. Ukuba usebenzisa isixhobo sakho ngokucotha kakhulu kwireyithi yokutya, ubeka umngcipheko wokuphinda usikwe iitshiphusi kunye nokukhawulezisa ukunxiba kwesixhobo. Ukuba usebenzisa isixhobo sakho ngokukhawuleza kakhulu kwireyithi yokutya, unokubangela ukwaphuka kwesixhobo. Oku kuyinyani ngakumbi ngesixhobo esincinci.

3. Ukusebenzisa i-Traditional Rughing.

Ngelixa urhabaxa lwemveli luyimfuneko ngamaxesha athile okanye lugqibelele, lungaphantsi koLuhlulo oluPhezulu lokuSebenza (HEM). I-HEM yindlela yokuqhankqalaza esebenzisa i-Radial Depth Depth of Cut (RDOC) kunye ne-Axial Depth of Cut (ADOC). Oku kusasazeka ukunxiba ngokulinganayo kuwo wonke umphetho wokusika, kuchitha ubushushu, kwaye kunciphisa ithuba lokusilela kwesixhobo. Ngaphandle kokunyusa ngokumangalisayo ubomi besixhobo, i-HEM inokuvelisa ukugqiba okungcono kunye nenqanaba eliphezulu lokususa isinyithi, iyenze ibe yinto eyomeleza yonke indawo kwivenkile yakho.

4. Ukusebenzisa iSixhobo sokubamba esingafanelekanga kunye nesiphumo saso kuBomi beSixhobo.

Iiparamitha ezifanelekileyo zokuqhuba zinempembelelo encinci kwiimeko zokubamba isixhobo esisezantsi. Uqhagamshelo olungalunganga lomatshini ukuya kwisixhobo lunokubangela ukuphuma kwesixhobo, ukutsalwa, kunye neendawo ezilahliweyo. Ngokuqhelekileyo, amanqaku amaninzi oqhagamshelwano umnikazi wesixhobo enawo ne-shank ye-l, kokukhona unxibelelwano lukhuselekile. I-Hydraulic kunye ne-shrink fit toolholders zibonelela ngokusebenza okwandisiweyo ngaphezulu kweendlela zokuqinisa oomatshini, njengoko kusenziwa uhlengahlengiso oluthile lwe-shank.

5. Ukungasebenzisi i-Various Helix/Pitch Geometry.

Isici kwiindidi zemill yokugqibela yokusebenza okuphezulu, i-helix eguquguqukayo, okanye i-pitch eguquguqukayo, ijometri lutshintsho olufihlakeleyo kwijometri yokuphela komgangatho. Olu phawu lwejometri luqinisekisa ukuba amaxesha exesha phakathi koqhagamshelwano olunqamlekileyo kunye nomsebenzi ahlukeneyo, kunokuba ngaxeshanye kunye nokujikeleza kwesixhobo ngasinye.Olu lwahluko lunciphisa incoko ngokunciphisa i-harmonics, eyandisa ubomi besixhobo kwaye ivelise iziphumo eziphezulu.

6. Ukukhetha i-Coating engalunganga inokunxiba kwi-Tool Life.

Ngaphandle kokuba kubiza kancinci, isixhobo esinokwaleka elungiselelwe imathiriyeli yakho yomsebenzi sinokwenza wonke umahluko. Iingubo ezininzi zokwaleka zinyusa i-lubricity, zicotha ukunxitywa kwezixhobo zendalo, ngelixa ezinye zinyusa ubulukhuni kunye nokuxhathisa kwe-abrasion. Nangona kunjalo, akuzona zonke iingubo ezifanelekileyo kuzo zonke izinto eziphathekayo, kwaye umehluko ubonakala kakhulu kwizinto ezinqabileyo kunye ne-non-ferrous. Ngokomzekelo, i-Aluminium Titanium Nitride (i-AlTiN) yokugubungela inyusa ubulukhuni kunye nokumelana nobushushu kwizinto ze-ferrous, kodwa inobudlelwane obuphezulu kunye ne-aluminium, ebangela ukunamathela komsebenzi kwisixhobo sokusika. Ingubo ye-Titanium Diboride (TiB2), kwelinye icala, inobudlelwane obuphantsi kakhulu kwi-aluminium, kwaye ithintela ukusika ukwakhiwa kunye nokupakishwa kwe-chip, kwaye yandisa ubomi besixhobo.

7. Ukusebenzisa ubude obude bokusika.

Ngelixa ubude obude bokusika (LOC) buyimfuneko ngokupheleleyo kwimisebenzi ethile, ngakumbi ekusebenzeni kokugqiba, kunciphisa ukuqina kunye namandla esixhobo sokusika. Njengomgaqo jikelele, i-LOC yesixhobo kufuneka ibe lixesha elide njengoko ifuneka ukuze kuqinisekiswe ukuba isixhobo sigcina ubuninzi be-substrate yaso yokuqala kangangoko kunokwenzeka. Okukhona i-LOC yesixhobo ithatha ixesha elide kokukhona sichanabeka ngakumbi ekuphambukeni, sinciphisa ubomi baso besixhobo esisebenzayo kunye nokwandisa ithuba lokwaphuka.

8. Ukukhetha ukubala kweFlute engalunganga.

Ngokulula njengoko kubonakala ngathi, ukubala kwefluti yesixhobo kunempembelelo ethe ngqo kwaye ephawulekayo ekusebenzeni kwayo kunye neeparamitha ezisebenzayo. Isixhobo esinefluti esezantsi (2 ukuya ku-3) sineentlambo ezinkulu zefleyiti kunye nombindi omncinci. Njengakwi-LOC, i-substrate encinci eseleyo kwisixhobo sokusika, ibuthathaka kwaye ingaphantsi kokuqina. Isixhobo esinembande ephezulu (5 okanye ngaphezulu) ngokwendalo sinondoqo omkhulu. Nangona kunjalo, ukubala kwefluti ephezulu akusoloko kubhetele. Ubalo lweflute esezantsi luqhele ukusetyenziswa kwi-aluminiyam kunye nezixhobo ezingenayo i-ferrous, ngokuyinxenye ngenxa yokuba ukuthamba kwezi zixhobo kuvumela ukuguquguquka okuthe kratya okunyuka kwamaxabiso okususwa kwesinyithi, kodwa nangenxa yeepropathi zeetshiphusi zazo. Izinto ezingezizo ezoni zihlala zivelisa ixesha elide, iitshiphusi zentambo kunye nenani elisezantsi lefleyiti linceda ukunciphisa ukusika itshiphu. Izixhobo zokubala zefleyiti eziphakamileyo zihlala ziyimfuneko kwimathiriyeli eyongeziweyo eyongeziweyo, zombini ngokwamandla azo andayo kwaye ngenxa yokuba ukusika itshiphu akuyongxaki kangako kuba ezi mathiriyeli zihlala zivelisa iitshiphusi ezincinci kakhulu.

Ukuba unomdla kwiimveliso ze-tungsten carbide kwaye ufuna ulwazi oluninzi kunye neenkcukacha, unakoQHAGAMSHELANA NATHIngefowuni okanye ngeposi ekhohlo, okanyeSITHUMELE imeyileemazantsi eli phepha.
