Zambiri za Tungsten Carbide End Mills ndi Zomwe Zingalephereke

Kodi mphero zomaliza zimapangidwa kuchokera ku carbide?

Mapeyo ambiri amapangidwa kuchokera ku cobalt steel alloys - amatchedwa HSS (High Speed ​​Steel), kapena kuchokera ku tungsten carbide. Kusankhidwa kwa zinthu za mphero yomwe mwasankha kumatengera kuuma kwa chogwirira ntchito chanu komanso liwiro lalikulu la spindle la makina anu.

Kodi mphero yolimba kwambiri ndi iti?

Carbide mapeto mphero.

Carbide end Mills ndi imodzi mwa zida zovuta kwambiri zodulira zomwe zilipo. Pafupi ndi diamondi pali zida zina zochepa zolimba kuposa carbide. Izi zimapangitsa kuti carbide ikhale yokhoza kupanga pafupifupi chitsulo chilichonse ngati ichita bwino. Tungsten Carbide imagwera pakati pa 8.5 ndi 9.0 pa Moh's hardness sikelo, ndikupangitsa kuti ikhale yolimba ngati diamondi.

Kodi mphero yabwino kwambiri yachitsulo ndi iti?

Makamaka, mphero zomaliza za carbide zimagwira ntchito bwino pazitsulo ndi ma alloys ake chifukwa zimakhala ndi matenthedwe ambiri ndipo zimagwira ntchito bwino pazitsulo zolimba. Carbide imagwiranso ntchito mothamanga kwambiri, zomwe zikutanthauza kuti chodulira chanu chimatha kupirira kutentha kwambiri ndipo chingalepheretse kuwonongeka ndi kung'ambika kwambiri. Mukamaliza zitsulo zosapanga dzimbiri, chiwerengero cha chitoliro chachikulu ndi / kapena helix yapamwamba imafunika kuti pakhale zotsatira zabwino. Kumaliza mphero zazitsulo zosapanga dzimbiri kudzakhala ndi ngodya ya helix yopitilira madigiri 40, ndi chitoliro chowerengera 5 kapena kupitilira apo. Kuti mupeze njira zomalizitsira mwamphamvu, kuchuluka kwa zitoliro kumatha kuchoka pa zitoliro 7 mpaka 14.

Chabwino n'chiti, HSS kapena carbide mapeto mphero?

Solid Carbide imapereka kukhazikika bwino kuposa chitsulo chothamanga kwambiri (HSS). Ndiwopanda kutentha kwambiri ndipo amagwiritsidwa ntchito pothamanga kwambiri pazitsulo zotayira, zinthu zopanda ferrous, mapulasitiki ndi zida zina zolimba kumakina. Makina omaliza a Carbide amapereka kukhazikika bwino ndipo amatha kuthamanga 2-3X mwachangu kuposa HSS.

Chifukwa chiyani mphero zomaliza zimalephera?

1. Kuthamanga Mothamanga Kwambiri Kapena Mochedwa KwambiriIngakhudze Moyo wa Chida.

Kuthamangitsa chida mwachangu kwambiri kungayambitse kukula kwa chip kapena kulephera kwa zida zowopsa. Mosiyana ndi zimenezi, kutsika kwa RPM kungayambitse kutembenuka, kutsirizitsa koyipa, kapena kutsika mtengo kuchotsa zitsulo.

2. Kudyetsa Pang'ono Kapena Kwambiri.

Chinthu chinanso chovuta kwambiri cha liwiro ndi chakudya, kuchuluka kwa chakudya chabwino kwa ntchito kumasiyana kwambiri ndi mtundu wa zida ndi zida zogwirira ntchito. Ngati mugwiritsa ntchito chida chanu mochedwa kwambiri, mumakhala pachiwopsezo chodula tchipisi ndikuwonjezera kuvala kwa zida. Ngati mugwiritsa ntchito chida chanu mwachangu kwambiri, mutha kuyambitsa kusweka kwa chida. Izi ndizowona makamaka ndi zida zazing'ono.

3. Kugwiritsa Ntchito Chikhalidwe Chachikale.

Ngakhale kukakamiza kwachikhalidwe kumakhala kofunikira nthawi zina kapena koyenera, nthawi zambiri kumakhala kotsika poyerekeza ndi High Efficiency Milling (HEM). HEM ndi njira yowonongeka yomwe imagwiritsa ntchito Radial Depth of Cut (RDOC) ndi Axial Depth of Cut (ADOC). Izi zimafalitsa kuvala molingana m'mphepete mwake, zimachotsa kutentha, komanso zimachepetsa mwayi wolephera kwa zida. Kupatula kuchulukirachulukira kwa moyo wa zida, HEM imatha kupanganso kutha kwabwinoko komanso kutsika kwachitsulo chokwera, ndikupangitsa kuti shopu yanu ikhale yabwino kwambiri.

4. Kugwiritsa Ntchito Molakwika Chida Chogwira ndi Mmene Zimakhalira pa Zida Zamoyo.

Ma parameter oyendetsa bwino amakhala ndi mphamvu zochepa pazida zosakwanira. Kusalumikizana bwino kwa makina ndi chida kungayambitse kutha kwa zida, kutulutsa, ndi zida zowonongeka. Nthawi zambiri, malo ochulukirachulukira omwe ali ndi chida ali ndi shank ya l, ndiye kuti kulumikizanako kumakhala kotetezeka kwambiri. Zida zogwiritsira ntchito ma hydraulic ndi shrink fit fitness zimapereka ntchito yowonjezera pa njira zomangirira zamakina, monganso kusintha kwa shank.

5. Osagwiritsa Ntchito Zosiyanasiyana za Helix/Pitch Geometry.

Mawonekedwe amitundu yosiyanasiyana yama mphero apamwamba, helix yosinthika, kapena phula losinthika, geometry ndikusintha kosawoneka bwino kwa geometry yomaliza ya mphero. Mawonekedwe a geometrical amatsimikizira kuti nthawi yapakati pakati pa kulumikizana kwapang'onopang'ono ndi gawo logwirira ntchito ndi yosiyanasiyana, osati nthawi imodzi ndi kasinthasintha wa chida chilichonse.Kusiyanasiyana kumeneku kumachepetsa macheza pochepetsa ma harmonics, omwe amawonjezera moyo wa zida ndikupanga zotsatira zabwino kwambiri.

6. Kusankha Chophimba Cholakwika Chikhoza Kuvala pa Zida Moyo.

Ngakhale ndizokwera mtengo kwambiri, chida chokhala ndi zokutira chokongoletsedwa ndi zida zanu zogwirira ntchito chingapangitse kusiyana konse. Zopaka zambiri zimawonjezera mafuta, kuchepetsa kuvala kwa zida zachilengedwe, pomwe zina zimawonjezera kuuma komanso kukana abrasion. Komabe, si zokutira zonse zomwe zili zoyenera ku zipangizo zonse, ndipo kusiyana kumawonekera kwambiri muzinthu zachitsulo komanso zopanda chitsulo. Mwachitsanzo, zokutira za Aluminium Titanium Nitride (AlTiN) zimawonjezera kuuma ndi kukana kutentha muzinthu zachitsulo, koma zimakhala zogwirizana kwambiri ndi aluminiyamu, zomwe zimapangitsa kuti ntchitoyo igwirizane ndi chida chodulira. Chophimba cha Titanium Diboride (TiB2), kumbali ina, chimakhala chochepa kwambiri chogwirizana ndi aluminiyamu, ndipo chimalepheretsa kumanga m'mphepete ndi kulongedza chip, ndikuwonjezera moyo wa zida.

7. Kugwiritsa Ntchito Utali Wautali Wodula.

Ngakhale kutalika kwa kudula (LOC) ndikofunikira kwambiri pa ntchito zina, makamaka pomaliza ntchito, kumachepetsa kulimba ndi mphamvu ya chida chodulira. Monga lamulo, LOC ya chida iyenera kukhala yayitali momwe ingafunikire kuonetsetsa kuti chidacho chimasunga gawo lake loyambirira momwe zingathere. Chida chotalikirapo LOC chimapangitsa kuti chisokonezeke kwambiri, kumachepetsa moyo wake wa chida ndikuwonjezera mwayi wosweka.

8. Kusankha Kuwerengera Kolakwika kwa Chitoliro.

Zosavuta momwe zikuwonekera, kuchuluka kwa chitoliro cha chida kumakhala ndi chiwopsezo chachindunji komanso chodziwika bwino pamachitidwe ake komanso magawo ake. Chida chokhala ndi chitoliro chochepa (2 mpaka 3) chimakhala ndi zigwa zazikulu za zitoliro ndi phata laling'ono. Monga ndi LOC, gawo locheperako lomwe limatsalira pachida chodulira, ndilofooka komanso lolimba kwambiri. Chida chokhala ndi zitoliro zambiri (5 kapena kupitilira apo) mwachilengedwe chimakhala ndi pachimake chokulirapo. Komabe, zitoliro zapamwamba sizikhala bwino nthawi zonse. Kuwerengera kwa zitoliro zotsika nthawi zambiri kumagwiritsidwa ntchito mu aluminiyamu komanso zinthu zopanda chitsulo, mwina chifukwa kufewa kwa zidazi kumathandizira kusinthasintha kwachulukidwe kochotsa zitsulo, komanso chifukwa cha tchipisi tawo. Zida zopanda chitsulo nthawi zambiri zimatulutsa nthawi yayitali, tchipisi tating'onoting'ono komanso kuchuluka kwa chitoliro chochepa kumathandiza kuchepetsa kudulidwa kwa chip. Zida zowerengera zitoliro zapamwamba nthawi zambiri zimakhala zofunikira pazida zolimba zolimba, chifukwa champhamvu komanso chifukwa kudula kwa chip sikudetsa nkhawa chifukwa zidazi nthawi zambiri zimatulutsa tchipisi tating'ono.

Ngati mukufuna zinthu za tungsten carbide ndipo mukufuna zambiri ndi zambiri, mungatheLUMIKIZANANI NAFEpa foni kapena makalata kumanzere, kapenaTITUMIZENI MAIpansi pa tsamba ili.
