TitaniumNws tuaj yeem raug drilled thiab tapped, tab sis nws lub cev thiab tshuaj lom neeg tshwj xeeb ua rau nws nyuaj rau tshuab ntau dua li cov hlau zoo tib yam (xws li 45 steel) lossis aluminium alloys. Yog tias siv cov txheej txheem tsis raug, nws yog qhov yooj yim rau cov cuab yeej txiav kom hnav sai sai, nti, lossis txawm tias ua rau lub workpiece hlawv.
I. Vim li cas Titanium nyuaj rau tshuab?
Cov thermal conductivity tsis zoo: Titanium muaj cov thermal conductivity tsawg heev (kwv yees li ib - plaub ntawm cov hlau). Feem ntau ntawm cov cua sov tsim thaum lub sij hawm drilling los yog tapping accumulates ntawm ntug txiav thiab ntawm lub workpiece nto, es tsis yog nqa tawm nrog cov chips.
Tsawg Modulus ntawm Elasticity: Titanium dhau los ua elastic deformation thaum raug quab yuam. Thaum lub sij hawm tapping, nws zoo li "caij nplooj ntoos hlav rov qab" thiab tuav tus kais kom nruj, ua rau muaj kev kub ntxhov hauv lub zog uas tuaj yeem snap tus kais.
Kev siv tshuaj lom neeg siab: Thaum qhov kub thiab txias, titanium tuaj yeem ua rau tshuaj lom neeg nrog cov khoom siv (xws li cobalt thiab tungsten), ua rau "stick- rau- cuab yeej" phenomena uas ua rau chipping ntawm txiav ntug.
II. Cov ntsiab lus tseem ceeb rau Drilling
Kev xaiv cuab yeej:
Koj yuav tsum siv carbide laum khoom tshwj xeeb tsim los rau kev ua haujlwm titanium alloys. Standard high -Speed steel laum khoom hnav tawm sai heev.
Kev xyaum me ntsis nrog lub kaum sab xis ntawm 130℃-140℃raug pom zoo (piv rau 118℃rau cov hlau zoo tib yam), vim qhov no muab lub zog ntau dua thiab pab txhawb kev tawg.
Txiav Parameters:
Tsis tshua muaj siab ceev: Ntau yam pom zoo yog 10-25 m / min. Rau ib qho 10 hli laum me ntsis, lub spindle ceev yuav tsum yog kwv yees li 300-800 rpm.
Siab pub tus nqi: 0.05-0.15 hli ib kiv puag ncig. Tsis txhob qhuav -txiav rau hauv qab ntawm lub qhov, vim qhov no ua rau kev ua haujlwm hnyav.
Cooling thiab lubrication:
Siab- ntws, siab- dej siab- raws li cov kua dej (emulsion lossis semi- cov kua hluavtaws). Tsis txhob cia siab rau ib rab phom cua rau tshuab, raws li cov cua sov tsim yuav kub hnyiab tam sim ntawd.
Cov txheej txheem tshwj xeeb:
Siab -Txoj kev Drilling ceev: Yog tias muaj qee yam txwv, tshem qhov xyaum tam sim ntawd thaum 0.5 hli tseem nyob ua ntej nkag mus rau cov khoom siv kom tshem tawm qhov rov qab compression, tom qab ntawd xyaum.
Tsis txhob siv -siab additives uas muaj chlorides, vim lawv yuav ua rau muaj kev ntxhov siab corrosion tawg hauv titanium.
III. Cov ntsiab lus tseem ceeb rau Tapping
Tapping yog qhov nyuaj tshaj li qhov drilling thiab sawv cev rau lub raj mis hauv titanium machining. Cov kais dej yog qhov yooj yim heev rau kev tawg thaum ua haujlwm nrog me me - txoj kab uas hla (xws li M3 thiab me dua).
Coj mus rhaub xaiv:
Ua ntej kais dej ua los ntawm cobalt-muaj siab- ceev steel lossis hmoov- metallurgy siab- ceev steel.
Hom Flute: Helical flutes (rau hauv qhov) lossis helical -lub kaum ntse ntse (rau qhov dig muag qhov) yuav tsum tau siv. Ncaj-flute kais feem ntau siv tsis tau ntawm titanium.
Cov kais dej yuav tsum tau tsim nrog lub kaum sab xis loj thiab dav, asymmetrical flank kom txo tau qhov kev sib txhuam springback.
Pilot Qhov Diameter:
Lub qhov pilot yuav tsum loj. Tsis txhob suav nws raws li tus qauv xov pilot qhov specifications.
Cov mis mos Empirical: Pilot qhov taub ≈ nominal xov txoj kab uas hla × 0.8. Piv txwv li, rau ib tug M6 × 1.0 xov, ib tug pilot qhov ntawm Ø5.0 mm yog pom zoo (tus qauv steel qhov chaw siv Ø5.0, tab sis rau titanium, siv Ø5.0–5.1).
Lub chamfer qhov tob ntawm lub qhov pilot yuav tsum tshaj ib lub suab.
Tapping txheej txheem:
Kev Taw Qhia Tapping: Tom qab tapping 1/2 mus rau 1 tag nrho tig, thim rov qab cov kev taw qhia los ntawm 1/4 tig kom tawg chips thiab tso tawm lub zog rov qab. Tsis txhob kov txhua txoj kev mus rau hauv qab hauv ib qho mus.
Tshuab Tapping: Siv lub tshuab hloov pauv hloov pauv (nrog kev tiv thaiv torque), thiab tswj cov ntxaiv ceev ntawm 5 txog 15 RPM.
Lubrication:
Siv cov roj ntxhia ntshiab, roj castor, lossis tshwj xeeb titanium alloy tapping compound. Tsis txhob siv lub tshuab roj zoo tib yam lossis emulsion, vim tias lawv tsis muaj lubrication txaus.
Cov ntsiab lus thiab cov lus pom zoo:
Yog hais tias koj tsuas muaj ib tug qauv tes xyaum los yog lub rooj zaum xyaum thiab tsis muaj coolant:
Drilling: Koj tuaj yeem sim qhov no, tab sis koj yuav tsum tau nqa lub laum me ntsis txhua 3-5 vib nas this thiab txias nws los ntawm dipping ib tug txhuam rau hauv roj av lossis tshuab xaws roj.
Tapping: Tsis pom zoo. Rau cov xov me dua M6, qhov tshwm sim ntawm tus kais tawg tshaj 80%. Rau me me -batch ntau lawm, peb xav kom siv xov milling (milling threads nrog CNC milling tshuab) es tsis txhob tapping.
