Xaiv cov laum qhov zoo tshaj plaws rau drilling stainless hlau?

Stainless hlau tuaj yeem yog npau suav phem yog tias koj tsis muaj cov cuab yeej zoo. Kuv nco tag nrho cov ntawv ntawm nws ib zaug ua ntej kuv kawm zais cia. Xav kom zam txoj kev ntxhov siab ib yam nkaus?

Qhov zoo tshaj plaws laum cov khoom rau stainless hlau yog cobalt cov khoom siv nrog 135-degree faib taw tes. Lawv tiv thaiv tshav kub zoo dua, nyob ruaj khov dua, thiab txiav ntau dua li cov qauv hss lossis titanium-coated khoom.

Cia kuv qhia dab tsi uas kuv tau kawm tom qab xyoo ua haujlwm nrog hlau stainless. Cov kev pom no yuav txuag koj lub sijhawm, nyiaj, thiab mob taub hau ntau.

Puas yog nws zoo dua los laum stainless hlau ceev ceev lossis qeeb?

Tej zaum koj yuav xav nrawm nrawm txuag lub sijhawm, tab sis nrog stainless hlau, uas xav tuaj yeem thim rov qab. Kuv tau kawm cov lus qhia txoj kev nyuaj rau txoj haujlwm tseem ceeb. Dab tsi ceev cov haujlwm zoo tshaj?

Drilling stainless hlau yuav tsum tau ua qeeb nrog kev nyuaj siab. Qeeb qeeb (nyob ib ncig ntawm 300-400 rpm) tiv thaiv kev ua haujlwm ua haujlwm thiab cua sov ntau dhau uas ua rau cov khoom siv nyuaj rau txiav.

Qhov kev sib raug zoo ntawmDRILLING ceev¹Thiab kev vam meej nrog stainless hlau yog ib yam dab tsi kuv tau kawm ntau yam hauv kuv lub chaw tsim khoom. Thaum drilling sai sai, qhov kev sib txhuam tsim kev sib txhuam zoo kawg li thaum tsis tsuas yog dulls koj ntsis tab sis hloov tau cov khoom siv ntawm cov hlau stainless. Qhov tshwm sim no hu ua "Ua Haujlwm Hardening" ua rau cov steel nyuaj thiab tiv thaiv ntau yam li koj laum.

[1] Tshawb txoj cai drilling ceev yog qhov tseem ceeb rau kev ua tiav qhov tseeb thiab lub sijhawm ntev hauv lub neej hauv stainless hlau.

Kuv tau pom qhov chaw qab zib yog feem ntau yog ntawm 300-400 RPM rau feem ntau cov ntawv thov steel. Ntawm lub nrawm nrawm, cov txiav cov sij hawm kom tshem tawm cov khoom uas tsis muaj ntau lub cua sov ntau dhau. Siv cov roj txiav ntxiv txo kev sib txhuam, txuas ntxiv lub neej lub neej. Hauv peb cov kev ntsuam xyuas sib piv qeeb ceev ceev ceev ceev ceev ceev ceev ceev, thiab lub qhov ntev dua ntawm qhov nrawm dua nrog tsawg dua los ntawm cov npoo.

Nco ntsoov tias qhov kev ntsuas nruj yog qhov tseem ceeb raws li nrawm. Cia cov laum ua haujlwm tsis tau yuam nws, thiab koj yuav tau txais cov txiaj ntsig zoo dua.

Yog cobalt lossis titanium tho kev ua kom zoo dua rau cov hlau tsis muaj hlau?

Kuv twb tau siv ntau txhiab tus sib txawv tho cov khoom hauv lub xyoo, sim nrhiav qhov zoo meej phim rau stainless hlau. Nruab nrab ntawm Cobalt thiab Titanium, muaj tus yeej ntshiab, tab sis vim li cas thiaj xav tsis thoob.

Cobalt laum bits outperform titanium khoom rau stainless hlau. Cobalt cov khoom muaj 5-8% cobalt sib thoob thoob plaws hauv cov hlau, muab cov kub ua kom nce mus txog 1100℃F. Titanium khoom tsuas yog muaj cov hlau txuas tam sim ntawd ntawm cov hlau tawv stainless.

Qhov sib txawv ntawm kev cobalt thiab titanium bits tau pom meej tom qab kaw tsuas yog ob peb lub qhov hauv stainless hlau. Hauv peb cov chaw tsim khoom, peb tau tshawb ntsuam dav dav m35 cobalt cov khoom lag luam (muaj 52 khob (muaj 8% cobalt) tawm tsam titanium-coated hss.

Cov txiaj ntsig tau tawm tsam: lub titanium txheej, thaum xub thawj nyuaj, pib hnav tawm tom qab tsuas yog 5-7 qhov nyob rau hauv 304 qhov hauv 304 lub qhov hlau stainless. Thaum qhov no tshwm sim, qhov pib softer hss khoom siv dulls sai. Nyob rau hauv kev sib piv, txoj hlua cobalt tswj lawv txoj kev txiav kom ntev dua - hauv qee kis, ib qho m42 me me dhau 50 qhov ua ntej yuav tsum tau rov ua dua.

Tus yuam sij qhov sib txawv yog tias cobalt yog aloyed thoob plaws hauv tag nrho me ntsis, tsis yog coated rau saum npoo. Qhov no txhais tau txawm tias yog cov khoom siv me me, cov khoom cobalt tshiab tau nthuav tawm, tswj cov me ntsis ua kom tsis kam thiab tawv. Peb pom cov khoom m42, txawm tias ntau dua cov nqi pib, muab tus nqi qis tshaj plaws ib lub qhov thaum ua haujlwm nrog hlau stainless.

Uas tau hais tias, rau kev siv ntau zaus, cov khoom lag luam titanium yuav tsim nyog, tab sis rau ib qho kev ua haujlwm hnyav nrog stainless hlau, cobalt yog tus yeej ntshiab.

Dab tsi yog qhov dag kom drilling stainless hlau?

Muaj kev ua kom yuam kev yooj yim los drilling stainless hlau uas hloov txhua yam rau kuv. Ua ntej kuv tshawb pom nws, Kuv tau niaj hnub sib ntaus nrog cov khoom tsis muaj qab thiab cov qhov sib tw. Xav paub cov lus zais?

Qhov ua kom yuam kev kom drilling stainless hlau siv lub qhov tsav, siv cov kua tawm, tswj kom muaj kev ua kom muaj zog, thiab cov chips kom nruj heev. Cov kauj ruam no tiv thaiv ua haujlwm tawv thiab xyuas kom huv si, ua kom huv si yam tsis muaj kev ua phem koj cov khoom.

Los ntawm kuv kev ua si khiav lub tho kev lag luam tuam txhab, cov kev ua yuam kev tseem ceeb tshaj plaws yog cov kev ua kom ze rau cov txheej txheem drilling nws tus kheej. Pib nrog ib qho chaw puag ncig los kos qhov chaw txiav, tiv thaiv me ntsis los ntawm "taug kev" thoob plaws qhov nyuaj nto. Tom qab ntawd tho ib lub qhov tsav me me (li ib nrab ntawm txoj kab uas hla koj lub qhov kawg) uas txo qhov tsis kam rau qhov loj dua.

Kev txiav tawm cov kua yog qhov tseem ceeb kiag li - Kuv nyiam cov kua dej uas muaj cov txiv hmab uas tsis muaj zog rau cov hlau stainless, raws li lawv tsim cov nyom ntawm lub ntsis thiab cov khoom siv uas txo cov kev txhuam hniav. Thov nws dav thiab nquag thoob plaws lub drurring cov txheej txheem.

Lub siab uas koj thov teeb meem zoo kawg li. Tsawg heev thiab me ntsis rubs yam tsis muaj txiav, ua kom muaj cua sov. Ntau dhau thiab koj yuav pheej hmoo ua txhaum me ntsis. Qhov zoo tshaj plaws siab tso cai rau me ntsis los txiav txuas ntxiv tsis muaj stalling. Kuv qhia peb cov neeg yuav khoom mloog lub suab - lub suab zoo ib yam tsis muaj squealing qhia tau lub siab.

Thaum kawg, "PICH DRILLING"¹Cov txheej txheem tau txais kev cawm dim tsis muaj feem nyob rau hauv peb lub rhiav. Qhov no suav nrog rho tawm me ntsis kom pom cov chips thiab pub cov kua kom ncav cuag txoj kev txiav. Nrog stainless hlau, Kuv pom zoo kom tshem tawm txhua 3-4mm ntawm qhov tob rau ntshiab chips thiab txo cov cua sov thiab txo cov cua sov buildup.

[1] Kawm tau li cas txoj kev khib nyiab yuav cawm tau cov khoom thiab txhim kho qhov zoo ntawm koj qhov kev ua haujlwm drilling.

Los ntawm kev sib txuas cov txuj ci no, txawm tias tawv stainless ua rau tho, nrog qhov huv thiab txuas ntxiv lub neej.

Rau drilling stainless hlau ntse zoo, siv cov khoom cobalt, siv qeeb nrawm nrog kev ua kua dej nrawm, thiab ua kom muaj kev sib thooj. Cov kev coj ua no yuav ua rau koj huv, qhov zoo txhua lub sijhawm.
