Cov hom kev xyaum xyaum uas tuaj yeem siv tauCNC drilling thiab milling tshuabsuav nrog kev xyaum twist, U xyaum xyaum, ua nruj ua tsiv, thiab cov tub ntxhais xyaum xyaum.
Twist xyaum yog feem ntau yog siv nyob rau hauv ib lub taub hau xyaum presses rau xyaum yooj yim ib panels.Tam sim no lawv tsis tshua pom nyob hauv cov tuam txhab loj hauv Circuit Court, thiab lawv qhov tob tob tuaj yeem ncav cuag 10 npaug ntawm txoj kab uas hla ntawm qhov xyaum.
Thaum lub substrate pawg tsis siab, kev siv lub tes tsho tho tuaj yeem zam qhov sib txawv ntawm qhov drilling.CovCNC drilling tshuabsiv cov cemented carbide tsau shank laum, uas yog tus cwj pwm los ntawm lub peev xwm los hloov qhov xyaum.High positioning raug, tsis tas yuav siv lub tes tsho tho.Loj helix lub kaum sab xis, ceev nti tshem tawm ceev, haum rau high-ceev txiav.Nyob rau hauv tag nrho ntev ntawm lub nti flute, txoj kab uas hla ntawm lub laum yog ib tug inverted cone, thiab kev sib txhuam nrog lub qhov phab ntsa thaum lub sij hawm drilling yog me me, thiab qhov drilling zoo yog siab.Kev xyaum shank diameters yog 3.00mm thiab 3.175mm.
Lub laum me ntsis rau lub raj xa ntawv drilling feem ntau siv cov cemented carbide, vim tias epoxy iav daim ntaub coated tooj liab ntawv phaj hnav lub cuab yeej sai heev.Lub thiaj li hu ua cemented carbide yog ua los ntawm tungsten carbide hmoov raws li ib tug matrix thiab cobalt hmoov raws li ib tug binder los ntawm siab thiab sintering.Nws feem ntau muaj 94% tungsten carbide thiab 6% cobalt.Vim nws cov hardness siab, nws yog hnav-resistant, muaj ib tug tej yam lub zog, thiab yog haum rau high-ceev txiav.
Tsis toughness thiab nkig heev.Txhawm rau txhim kho kev ua haujlwm ntawm cemented carbide, qee qhov siv txheej txheej ntawm 5-7 microns ntawm cov tawv tawv titanium carbide (TIC) lossis titanium nitride (TIN) ntawm cov carbide substrate los ntawm cov tshuaj vapor deposition kom nws muaj zog dua.Ib txhia siv ion implantation technology los cog titanium, nitrogen, thiab carbon rau hauv lub matrix rau ib tug tej yam tob, uas tsis tsuas yog txhim kho lub hardness thiab lub zog, tab sis kuj cov implanted Cheebtsam yuav tsiv mus nyob rau hauv thaum lub laum me ntsis reground.Ib txhia siv lub cev txoj kev los tsim ib txheej ntawm pob zeb diamond zaj duab xis nyob rau sab saum toj ntawm lubxyaum me ntsis, uas zoo heev txhim kho lub hardness thiab hnav tsis kam ntawm laum ntsis.Lub hardness thiab lub zog ntawm cemented carbide tsis tsuas yog cuam tshuam rau qhov piv ntawm tungsten carbide thiab cobalt, tab sis kuj rau cov khoom ntawm cov hmoov.
Rau cov khoom zoo heev ntawm cemented carbide laum khoom, qhov nruab nrab qhov loj ntawm tungsten carbide theem nplej yog qis dua 1 micron.Hom kev xyaum no tsis tsuas yog siab hardness tab sis kuj txhim kho compressive thiab flexural zog.Yuav kom txuag tau tus nqi, ntau cov khoom xyaum siv tam sim no siv welded shank qauv.Tus thawj laum me ntsis yog ua los ntawm hard alloy tag nrho.Tam sim no lub laum rov qab shank yog ua los ntawm stainless hlau, uas zoo heev txo tus nqi.Txawm li cas los xij, vim yog siv cov khoom sib txawv, qhov sib txawv ntawm qhov sib txawv tsis zoo li qhov nyuaj tag nrho.Alloy laum khoom, tshwj xeeb tshaj yog rau me me diameters.
