Menene End Mill?

Babban yanki na ƙarshen niƙa shine farfajiyar silinda, kuma yankan gefen ƙarshen ƙarshen shine ƙarshen yankan na biyu.Ƙarshen niƙa ba tare da gefen tsakiya ba ba zai iya yin motsin ciyarwa tare da axial direction na mai yankan niƙa ba.Bisa ga ma'auni na ƙasa, diamita na ƙarshen niƙa shine 2-50 mm, wanda za'a iya raba shi zuwa nau'i biyu: ƙananan hakora da hakora masu kyau.Diamita na 2-20 shine kewayon madaidaiciyar shank, kuma diamita na 14-50 shine kewayon ƙwanƙwasa.
Ana samun daidaitattun injina na ƙarshen zamani tare da m da lallausan hakora.Adadin haƙoran haƙoran haƙora na ƙarshen niƙa shine 3 zuwa 4, kuma kusurwar helix β ya fi girma;Adadin haƙoran haƙoran haƙori na ƙarshen niƙa shine 5 zuwa 8, kuma kusurwar helix β ya fi karami.Kayan kayan yankan shine karfe mai sauri, kuma shank shine karfe 45.

Akwai nau'i-nau'i da yawa na masu yankan niƙa, waɗanda ake amfani da su don injunan niƙa na yau da kullun da injinan niƙa CNC don aiwatar da ramuka da madaidaiciyar kwane-kwane, da aiwatar da cavities, cores, da sifofi / kwane-kwane akan wuraren niƙa da cibiyoyi masu ban sha'awa.
Gabaɗaya an kasu masu yankan niƙa zuwa:
1. Flat karshen milling abun yanka, don niƙa mai kyau ko m, niƙa ragi, cire adadi mai yawa, niƙa mai kyau na ƙananan jiragen sama a kwance ko kwane-kwane;

2. Ball hanci milling abun yankadon kammala rabin-karewa da gama niƙa na filaye masu lanƙwasa;ƙananan masu yankan za su iya gama niƙa ƙananan hammata a kan tudu masu tsayi/ganuwar madaidaiciya.

3. The lebur karshen milling abun yanka yana dachamfering, wanda za'a iya amfani dashi don niƙa mai ƙazanta don cire adadi mai yawa, kuma yana iya ƙulla ƙananan ƙuƙumma a kan filaye masu kyau (dangane da saman tudu).

4. Samar da masu yankan niƙa, ciki har da masu yankan ƙwanƙwasa, masu yankan niƙa mai siffar T ko masu yankan ganga, masu yankan hakori, da masu yankan R na ciki.

5. Chamfering abun yanka, Siffar mai yankan tambari iri ɗaya ce da ta ƙawance, kuma an raba ta zuwa masu yankan niƙa don yin zagaye da ƙwanƙwasa.

6. Abun yanka T-dimbin yawa, iya niƙa T-dimbin yawa tsagi;

7. Mai yankan hakori, yana nika sifofin hakori iri-iri, kamar gears.

8. M abin yankan fata, mai yankan niƙa mai ƙaƙƙarfan ƙira wanda aka tsara don yankan aluminium da tagulla, waɗanda za a iya sarrafa su da sauri.

Akwai kayan gama gari guda biyu don masu yankan niƙa: ƙarfe mai sauri da siminti carbide.Idan aka kwatanta da na farko, na karshen yana da babban tauri da ƙarfi mai ƙarfi, wanda zai iya ƙara saurin gudu da ƙimar abinci, inganta yawan aiki, sa mai yankewa ya zama ƙasa da bayyane, da aiwatar da kayan aiki mai wuyar gaske kamar bakin karfe / titanium gami, amma farashin ya fi girma, kuma ƙarfin yanke yana canzawa da sauri.A cikin yanayin sauƙi don karya mai yanke.
