Chidziwitso choyambirira cha zida za NC, chidziwitso chachitsanzo cha tsamba la NC

Zofunikira za zida zamakina a CNC pazida zida

High kuuma ndi kuvala kukana
Kuuma kwa gawo lodula la chida kuyenera kukhala kokulirapo kuposa kuuma kwa zida zogwirira ntchito.Kuchuluka kwa kuuma kwa zida za zida, kumapangitsanso kukana kwake kuvala.Kuuma kwa zida za chipangizo kutentha kutentha kuzikhala pamwamba pa HRC62.Kuuma kumatha kukhala kokwera kuposa kwa wambaCNC Machining magawo.
Mphamvu zokwanira ndi kulimba
Chidacho chimanyamula kupanikizika kwakukulu m'kati mwa kudula kwambiri.Nthawi zina, zimagwira ntchito pansi pa zovuta komanso kugwedezeka.Kuti chida chitha kusweka ndi kusweka, chidacho chiyenera kukhala ndi mphamvu zokwanira komanso zolimba.Nthawi zambiri, mphamvu yopindika imagwiritsidwa ntchito kuyimira mphamvu ya chidacho, ndipo phindu lamphamvu limagwiritsidwa ntchito kuyimira kulimba kwa chidacho.
kukana kutentha kwambiri
Kukana kutentha kumatanthawuza kugwira ntchito kwa zida zothandizira kuti zikhalebe zolimba, kukana kuvala, mphamvu ndi kulimba pansi pa kutentha kwakukulu.Ndilo chizindikiro chachikulu kuyeza ntchito kudula zida zida.Ntchitoyi imatchedwanso kuuma kofiira kwa zida za zida.
Zabwino matenthedwe madutsidwe
Kuchuluka kwa kutentha kwa chipangizocho kumakhala kotentha kwambiri, kumapangitsanso kutentha kwa chipangizocho, zomwe zimathandiza kuchepetsa kutentha kwa chida ndikuwongolera kulimba kwa chidacho.
Good processability
Kuti atsogolere pokonza ndi kupanga zida, zida zida zimayenera kukhala zabwino processing katundu, monga forging, anagubuduza, kuwotcherera, kudula ndi grindability, katundu kutentha kutentha ndi mkulu-kutentha pulasitiki mapindikidwe katundu wa zipangizo chida.Pazida zokhala ndi simenti ya carbide ndi zida za ceramic, ma sintering abwino komanso opangira mphamvu amafunikiranso.

Mtundu wa zida zothandizira

zitsulo zothamanga kwambiri
Chitsulo chothamanga kwambiri ndi chitsulo cha alloy chopangidwa ndi W, Cr, Mo ndi zinthu zina za alloy.Imakhala ndi kukhazikika kwamafuta ambiri, mphamvu yayikulu komanso kulimba, komanso kulimba kwina ndi kukana kuvala, kotero ndiyoyenera kukonza zitsulo zopanda chitsulo ndi zida zosiyanasiyana zachitsulo.Komanso, chifukwa cha luso processing bwino, ndi oyenera kupanga zida zovuta kupanga, makamaka ufa zitsulo mkulu liwiro zitsulo, amene ali anisotropic mawotchi katundu ndi kuchepetsa quenching mapindikidwe, Ndi oyenera kupanga mwatsatanetsatane ndi zovuta kupanga zida.
Chitsulo cholimba
Carbide yokhala ndi simenti imakhala yolimba kwambiri komanso kukana kuvala.Pamene kudulaCNC kutembenuza magawo, ntchito yake ndi yabwino kuposa yachitsulo chothamanga kwambiri.Kulimba kwake kumakhala kangapo mpaka kambirimbiri kuposa chitsulo chothamanga kwambiri, koma kulimba kwake ndikosavuta.Chifukwa cha ntchito yake yabwino yodulira, imagwiritsidwa ntchito kwambiri ngati zida.

Kugawa ndi kuyika chizindikiro cha ma carbides opangidwa ndi simenti pazida zodulira

Chokutidwa ndi tsamba
1) Zida zokutira za njira ya CVD ndi TiC, yomwe imawonjezera kulimba kwa zida za carbide zokhala ndi simenti nthawi 1-3.Kupaka makulidwe;Mphepo yamkuntho ndi yobiriwira;Ndizothandiza kuwongolera moyo wothamanga.
2) Zida zokutira za njira ya PVD yoyika nthunzi ndi TiN, TiAlN ndi Ti (C, N), zomwe zimathandizira kulimba kwa zida za carbide zokhala ndi simenti nthawi 2-10.Chophimba chochepa;Mphepete yakuthwa;Ndizopindulitsa kuchepetsa mphamvu yocheka.
★ makulidwe apamwamba a zokutira ≤ 16um
CBN ndi PCD
Cubic boron nitride (CBN) Kulimba ndi kutenthetsa kwa machubiki boron nitride (CBN) ndizotsika kwambiri kuposa diamondi, ndipo zimakhala ndi kukhazikika kwamafuta komanso kukhazikika kwamankhwala abwino.Choncho, ndi oyenera Machining zitsulo zolimba, chitsulo cholimba, superalloy ndi simenti carbide.
Polycrystalline diamondi (PCD) PCD ikagwiritsidwa ntchito ngati chida chodulira, imayikidwa pagawo la simenti ya carbide, ndipo imatha kumaliza kusamva, kuuma kwakukulu kwazinthu zopanda zitsulo komanso zopanda chitsulo monga carbide, zoumba, aluminiyamu yapamwamba ya silicon.
★ ISO machine clamp blade material classification ★
Zigawo zachitsulo: P05 P25 P40
Chitsulo chosapanga dzimbiri: M05 M25 M40
Chitsulo chachitsulo: K05 K25 K30
★ Chiwerengerocho ndi chaching'ono, tsamba limakhala lolimba kwambiri, kukana kuvala kwa chida kumakhala bwino, ndipo kumapangitsanso kukana kwambiri.
★ Kukula kwa chiwerengerocho, tsambalo limakhala lofewa, ndiye kuti kukana kwamphamvu komanso kusamva bwino kwa chida kumasokonekera.
Imasinthidwa kukhala blade model ndi malamulo oyimira ISO

1. Khodi yoyimira mawonekedwe a tsamba

2. Khodi yoyimira mbali yakumbuyo ya m'mphepete mwawo

3. Code yoyimira kulolerana kwa tsamba

4. Khodi yoyimira kuthyoka kwa chip ndi kutsekereza mawonekedwe a tsamba

5. Kuyimiridwa ndi kutalika kwa kudula

6. Khodi yoyimira makulidwe a tsamba

7. Khodi yoyimira m'mphepete mwa kupukuta ndi ngodya ya R

Tanthauzo la ziwerengero zina
8 amatanthauza malamulo osonyeza zosowa zapadera;
9 imayimira mayendedwe a chakudya, mwachitsanzo, nambala R imayimira chakudya chakumanja, code L imayimira chakudya chakumanzere, ndipo N imayimira chakudya chapakati;
10 imayimira mtundu wa chip breaking groove;

kudula liwiro
Kuwerengera liwiro la kudula Vc:

Mu formula:
D - kuzungulira kozungulira kwa workpiece kapena nsonga ya chida, unit: mm
N - liwiro lozungulira la chogwirira ntchito kapena chida, gawo: r/min
Kuthamanga kwa Machining Thread ndi Ordinary Lathe
Liwiro la spindle n potembenuza ulusi.Podula ulusi, liwiro la spindle la lathe limakhudzidwa ndi zinthu zambiri, monga kukula kwa ulusi (kapena lead) wa chogwirira ntchito, kukweza ndi kutsitsa kwa injini yoyendetsa, komanso kuthamanga kwa kumasulira kwa ulusi.Chifukwa chake, pamakina osiyanasiyana a CNC, pali kusiyana kwina mu liwiro la spindle n pakutembenuza ulusi.Zotsatirazi ndi njira yowerengera liwiro la spindle potembenuza ulusi pazitsulo za CNC:

Mu formula:
P - phula kapena ulusi wa ulusi wa workpiece, unit: mm.
K - inshuwaransi coefficient, nthawi zambiri 80.
Kuwerengera kwa kuya kwa chakudya chilichonse pakupanga ulusi

Chiwerengero cha njira zopangira ulusi

1) Makina osavuta

Njira yowerengera mozama ya chakudya cha makina ochapira: f rough=0.5 R
Kumene: R -- nsonga ya chida arc radius mm
F -- akhakula Machining chida chakudya mm
2) Kumaliza

Mu chilinganizo: Rt —— kuya kwa mizere µ m
F —— Mlingo wa chakudya mm/r
r ε -- Radius ya chida nsonga arc mm
Siyanitsani kutembenuka kwaukali ndi kumaliza molingana ndi kuchuluka kwa chakudya ndi chip breaking groove
F ≥ 0,36 makina ovuta
0.36 ＞ f ≥ 0.17 theka kumaliza
F ＜ 0.17 kumaliza kukonza
Sizinthu za tsamba koma chip breaking groove yomwe imakhudza kukonza ndi kutsiriza kwa tsamba.Mphepete mwake ndi yakuthwa ngati chamfer ndi yosakwana 40um.
