Xaiv qhov zoo twist laum me ntsis rau koj qhov project yuav nkag siab peb yam tseem ceeb: cov khoom, txheej, thiab geometric nta. Txhua yam ntawm cov khoom no ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm thiab ua haujlwm ntev ntawm lub laum me ntsis. Ntawm no yog saib ze dua ntawm yuav ua li cas txiav txim siab paub.
Khoom siv
1. High-Speed Steel (HSS):
High-Speed Steel (HSS) yog ib qho tseem ceeb hauv kev txiav cov cuab yeej rau ntau tshaj ib puas xyoo, muaj nuj nqis rau nws daim ntawv thov dav thiab pheej yig. HSS laum cov khoom paub txog lawv cov kev ua tau zoo, ua tau zoo nrog ob qho kev xyaum tes thiab cov platforms ruaj khov xws li laum presses. Ib qho txiaj ntsig tseem ceeb ntawm HSS yog nws lub peev xwm rov ua kom zoo dua qub, txhim kho lub neej ntev ntawm cov khoom siv laum thiab ua rau nws xaiv tus nqi zoo rau cov cuab yeej tshuab dhos ib yam. Tsis tas li ntawd, HSS muaj cov qib sib txawv, txhua qhov sib txawv ntawm cov ntsiab lus sib txawv los ua kom haum rau cov kev xav tau tshwj xeeb. Qhov no ntau yam hauv cov qib steel ntxiv rau kev hloov kho ntawm HSS, ua rau nws muaj ntau yam thiab tseem ceeb hauv kev ua haujlwm sib txawv.
2. Cobalt HSS (HSSE lossis HSSCO):
Piv nrog rau HSS tsoos, Cobalt HSS qhia superior hardness thiab kub endurance. Qhov kev txhim kho hauv cov khoom no ua rau muaj kev txhim kho kev puas tsuaj, ua rau HSSE laum cov khoom siv tau ntev dua thiab ua haujlwm tau zoo. Kev koom ua ke ntawm cobalt hauv HSSE tsis yog tsuas yog ua rau nws muaj zog tiv thaiv kev puas tsuaj, tab sis kuj txhim kho nws lub neej tag nrho. Ntau yam zoo li tus qauv HSS, HSSE cov khoom khaws cov txiaj ntsig ntawm kev rov ua kom pom tseeb, uas txuas ntxiv lawv lub neej siv tau. Lub xub ntiag ntawm cobalt hauv HSSE ua rau cov khoom no tshwj xeeb tshaj yog tsim nyog rau kev xav tau ntau dua qhov kev ua haujlwm drilling qhov chaw ua haujlwm ntev thiab ua haujlwm tsis zoo yog qhov tseem ceeb.
3. Carbide:
Carbide yog hlau matrix composite, feem ntau yog ua los ntawm tungsten carbide nrog ntau yam binders. Nws tseem ceeb tshaj HSS nyob rau hauv hardness, kub endurance, thiab abrasion kuj. Txawm tias kim dua, cov cuab yeej carbide ua tau zoo nyob rau hauv lifespan thiab machining ceev. Lawv xav tau cov cuab yeej tshwj xeeb rau kev rov ua dua.
Txheej
Laum txheej txheej sib txawv thiab raug xaiv raws li daim ntawv thov. Nov yog cov ntsiab lus luv luv rau qee cov txheej txheem:
1. Uncoated (Caj):
Nws yog xim ntau tshaj plaws rau HSS laum khoom. Zoo tagnrho rau cov ntaub ntawv mos xws li txhuas alloys thiab cov pa roj carbon tsawg, cov cuab yeej tsis muaj coated yog qhov pheej yig tshaj plaws.
2. Dub Oxide Txheej:
Muab cov roj lubrication zoo dua thiab ua haujlwm kub dua li cov cuab yeej tsis muaj coated, txhim kho lifespan ntau dua 50%.
3. Titanium Nitride (TiN) Txheej:
Titanium-coated laum khoom ua tau zoo nyob rau hauv ntau daim ntawv thov scenarios vim lawv cov yam ntxwv ua tau zoo. Ua ntej, Nws txhim kho hardness thiab abrasion tsis kam los ntawm txheej, cia me ntsis kom nyob twj ywm ntse thaum drilling los ntawm cov ntaub ntawv nyuaj, thiab muab lub neej ntev kev pab cuam. Cov khoom no txo cov kev sib txhuam thiab cov cua sov tsim, ua rau kev txiav kom zoo thaum tiv thaiv me ntsis los ntawm overheating. Titanium-plated khoom yog tsim rau siv ntau yam ntaub ntawv, xws li stainless hlau, txhuas thiab ntoo, ua rau lawv zoo tagnrho rau engineering thiab tsev neeg daim ntaub ntawv. Tsis tas li ntawd, cov khoom no nkag mus rau cov ntaub ntawv sai dua thiab huv dua, muab qhov chaw txiav zoo dua. Thaum titanium-plated xyaum xyaum yuav raug nqi ntau dua li kev xyaum ua haujlwm, lawv cov kev ua haujlwm siab thiab lub neej ntev ua rau lawv muaj txiaj ntsig zoo rau kev nqis peev rau cov ntawv thov uas xav tau kev ua haujlwm siab thiab kev txiav meej.
4. Aluminium Titanium Nitride (AlTiN) Txheej:
Ua ntej, AlTiN txheej yog cov cua sov uas tsis muaj zog, ua rau lawv ua tau zoo hauv kev txiav ceev thiab ua haujlwm ntawm cov hlau kub kub. Qhov thib ob, txheej txheej no ua rau muaj txiaj ntsig zoo dua qub thiab txhim kho lub neej ntawm cov cuab yeej, tshwj xeeb tshaj yog thaum siv cov ntaub ntawv nyuaj xws li stainless hlau, titanium alloys thiab npib tsib xee-raws li alloys. Tsis tas li ntawd, AlTiN txheej txo cov kev sib txhuam ntawm cov laum me ntsis thiab cov khoom ua haujlwm, txhim kho kev ua haujlwm zoo thiab pab kom ua tiav qhov kev txiav zoo dua. Nws kuj muaj qhov zoo oxidation tsis kam thiab tshuaj lom neeg ruaj khov, ua kom nws tswj tau qhov kev ua tau zoo hauv qhov chaw ua haujlwm hnyav. Nyob rau hauv tag nrho, AlTiN-coated xyaum yog zoo tagnrho rau high-speed, high-precision machining daim ntaub ntawv, thiab tshwj xeeb tshaj yog haum rau tuav cov ntaub ntawv nyuaj uas ua rau muaj kev sib tw rau cov pa xyaum ua tej yam.
Geometric nta
1. Ntev:
Qhov piv ntawm qhov ntev rau txoj kab uas hla cuam tshuam rigidity. Xaiv ib lub laum me ntsis nrog lub flute ntev txaus rau nti khiav tawm thiab qhov tsawg tshaj plaws tuaj yeem txhim kho rigidity thiab cuab yeej lub neej. Tsis txaus flute ntev yuav ua rau lub ntsis. Muaj ntau yam qauv ntev los xaiv hauv khw. Qee qhov ntev yog Jobber, stubby, DIN 340, DIN 338, thiab lwm yam.
2. Drill Point Angle:
Lub kaum sab xis 118 ° yog ib qho rau cov hlau mos xws li cov hlau tsis tshua muaj hlau thiab txhuas. Nws feem ntau tsis muaj peev xwm tswj hwm tus kheej, xav tau lub qhov pilot. Lub kaum sab xis 135 °, nrog rau nws tus kheej qhov chaw, tshem tawm qhov xav tau ntawm qhov chaw nruab nrab, txuag lub sijhawm tseem ceeb.
Hauv kev xaus, xaiv txoj cai twist laum me ntsis suav nrog ntsuas qhov xav tau ntawm cov khoom siv tho, qhov xav tau lifespan thiab kev ua tau zoo ntawm qhov me me, thiab cov kev cai tshwj xeeb ntawm koj qhov project. Kev nkag siab txog cov xwm txheej no yuav ua rau koj xaiv qhov zoo tshaj plaws thiab siv tau zoo rau koj cov kev xav tau.
