Nyob rau hauv precision sib tsoo, lubvitrified sib tsoo logfeem ntau piav raws li "cov hniav ntawm kev lag luam." Tab sis xaiv lub log tsis raug tuaj yeem ua ntau dua li txo kev sib tsoo kom zoo. Nws tuaj yeem ua rau cov khoom ua haujlwm puas tsuaj, muab qhov tsis tsim nyog rau ntawm lub tshuab, thiab tseem tsim kev nyab xeeb. Qhov tseem ceeb yog xaiv lub log raws li qhov sib tsoo tiag tiag es tsis yog tsom rau ib qho tshwj xeeb.
5 Feem ntau yuam kev thaum xaiv lub Vitrified Sib Tsoo Log
Thawj qhov yuam kev: Tsuas saib ntawm nqe thiab tsis quav ntsej txog kev ua tau zoo
Dab tsi mus tsis ncaj ncees lawm:
Qee tus neeg yuav khoom tsuas yog tsom rau tus nqi qis tshaj plaws thaum saib xyuas kev sib tsoo, lub neej ntawm lub log, thiab kev ua haujlwm zoo. Qhov tshwm sim feem ntau yog ib rooj plaub ntawm "pheej yig mus yuav, kim siv." Kev tsim khoom tsawg, kev hloov lub log tsis tu ncua, thiab cov khoom seem ntau dua tuaj yeem thawb tus nqi tiag tiag.
Yuav zam tau li cas:
Xav txog cov nqi tag nrho, tsis yog nqi tsev xwb. Piv txwv li, lub log kim dua tuaj yeem muab 30% kev sib tsoo ntau dua thiab 50% kev pabcuam ntev dua. Txawm hais tias tus nqi pib yog siab dua, tus nqi ntawm ib qho workpiece yuav qis dua. Txuag ntawm tus nqi yuav khoom ib leeg tuaj yeem yooj yim ua rau cov nqi khiav lag luam ntau dua.
Thaum sib piv cov kev xaiv sib txawv vitrified sib tsoo log, cov neeg yuav khoom yuav tsum xav txog lub neej ntawm lub log, tus nqi tshem tawm cov khoom siv, kev hnav khaub ncaws ntau zaus, thiab qhov yuav tsum tau ua tiav ua ke tsis yog saib tus nqi ib leeg.
Qhov yuam kev thib ob: Xaiv qhov tsis ncaj ncees lawm abrasive
Dab tsi mus tsis ncaj ncees lawm:
Qhov no yog ib qho ntawm feem ntau xaiv yuam kev vim hais tias txawv abrasive hom muaj ntau yam sib txawv.
Brown aluminium oxide (A):Cov tawv tawv thiab kuj pheej yig, ua rau nws haum rau siab - tensile - lub zog hlau xws li carbon steel thiab hlau alloy. Txawm li cas los xij, nws tsis yog qhov kev xaiv zoo rau kev sib tsoo cemented carbide.
Dawb aluminium oxide (WA):Nyuaj tab sis me ntsis tawv dua li xim av aluminium oxide. Nws cov nplej ntse txiav tau yooj yim rau hauv qhov chaw ua haujlwm, ua rau nws tsim nyog rau cov hlau tawv tawv, siab - steel ceev, thiab cov ntawv thov yuav tsum tau ua kom tiav qhov zoo.
Pink aluminium oxide (PA):Tougher dua dawb aluminium oxide thiab zoo haum rau kev sib tsoo cov cuab yeej steel, gauges, thiab zoo sib xws precision Cheebtsam uas nto qhov tseem ceeb.
Silicon carbide (C / GC):Ib qho tawv thiab ntse abrasive haum rau qis- tensile- cov ntaub ntawv muaj zog xws li cam khwb cia hlau, tsis yog -ferrous hlau, cemented carbide, iav, thiab ceramics.
Yuav zam tau li cas:
Txuas lub abrasive rau cov khoom. Ib yam li koj yuav tsis siv rab riam los txiav cov pob txha, koj yuav tsum tsis txhob xaiv cov abrasive yam tsis xav txog cov khoom ua haujlwm. Yog tias koj tsis paub meej, sab laj nrog pab pawg kws tshaj lij ntawm koj lub chaw muag khoom sib tsoo.
Qhov yuam kev thib peb: Piv txwv tias "Zoo dua yog ib txwm zoo dua"
Dab tsi mus tsis ncaj ncees lawm:
Ntau tus neeg siv xav tias lub log nyuaj yuav kav ntev dua thiab yog li xaiv qib siab hardness yam tsis xav txog kev sib tsoo. Qhov no tuaj yeem ua rau muaj ntau yam teeb meem:
1. Nplej nplej tsis tso:Thaum cov nplej abrasive ua npub, lawv tseem tuav hauv daim ntawv cog lus. Sib tsoo swarf tuaj yeem txhaws lub log nto, txo cov peev xwm txiav thiab ua kom muaj cua sov.
2. Workpiece hlawv:Kev sib tsoo ntau dhau tuaj yeem ua rau saum npoo tempering, tawg, thiab poob ntawm qhov tseeb.
3. Kev sib tsoo ntau dhau:Kev sib tsoo ntau dua tuaj yeem ua rau muaj kev pheej hmoo ntawm lub log puas lossis tawg.
Yuav zam tau li cas:
Log hardness yog hais txog kev tuav lub zog ntawm daim ntawv cog lus ntawm cov nplej abrasive, tsis yog lub hardness ntawm abrasive nws tus kheej. Qhov zoo tshaj plaws, cov nplej npub yuav tsum tso tawm thaum lub sijhawm kom cov nplej tshiab thiab ntse raug nthuav tawm. Qhov no yog lub log ntawm tus kheej - ua kom ntse.
Rau cov ntaub ntawv mos xws li cov hlau tsis muaj zog thiab tsis yog{0}} cov hlau tsis muaj hlau, feem ntau siv lub log nyuaj los tiv thaiv cov hmoov nplej los ntawm kev tso tawm sai heev.
Rau cov ntaub ntawv nyuaj xws li cemented carbide thiab hardened steel, lub log softer feem ntau yog tsim nyog dua vim tias nws tuav nws tus kheej zoo dua -sharpening thiab pab tiv thaiv kev sib tsoo kub.
Rau kev sib tsoo precision, lub log nyuaj me ntsis tuaj yeem raug xaiv thaum muaj qhov tseeb ntau dua thiab qhov ua tiav saum npoo. Qib hardness yuav tsum nco ntsoov muab xam nrog rau hom abrasive thiab kev sib tsoo thaum qhia txog lub log vitrified sib tsoo.
Fourth yuam kev: Ib txwm xaiv ib nrab - ntawm - - Txoj Kev Grit Loj
Dab tsi mus tsis ncaj ncees lawm:
Txhawm rau kom yooj yim rau kev yuav khoom thiab kev tsim khoom, qee cov neeg siv cia siab rau tag nrho - lub hom phiaj grit xws li F80 lossis F100 rau yuav luag txhua qhov kev sib tsoo.
Rau kev sib tsoo ntxhib, siv cov grit zoo tuaj yeem ua rau cov khoom lag luam tsawg heev - tshem tawm cov nqi thiab ua rau muaj kev pheej hmoo ntawm kev sib tsoo kub.
Rau kev sib tsoo tiav, siv cov xuab zeb ntxhib tuaj yeem tawm ntawm qhov chaw ntxhib thiab ua rau nws nyuaj rau kev ua tiav qhov yuav tsum tau muaj qhov tseeb thiab qhov chaw tiav.
Yuav zam tau li cas:
Kev sib tsoo ntxhib thiab siab - tshem tawm cov khoom lag luam zoo:Xaiv ib qho ntxhib grit, xws li F24-F60, rau qhov tob ntawm kev txiav ntau dua thiab cov khoom tshem tawm ntau dua.
Ua kom tiav kev sib tsoo thiab qhov chaw siab - ua kom tiav:Xaiv cov grit zoo, xws li F120-F360 los yog finer, kom ua tau ib tug smoother, ntau refined nto.
General semi{0}}ua tiav: A nruab nrab grit, xws li F60-F100, yog tsim rau kev sib tsoo nruab nrab.
Qhov yuam kev thib tsib: Tsis quav ntsej lub log qauv
Dab tsi mus tsis ncaj ncees lawm:
Lub log tus qauv- qhov sib piv ntawm cov nplej abrasive, daim ntawv cog lus, thiab qhov pores- yog qee zaum saib tsis tau. Lub log nrog cov qauv uas tuab heev tuaj yeem muaj cov nti tshem tawm tsis zoo thiab ua kom yooj yim thauj khoom. Lub log uas qhib dhau yuav hnav sai heev thiab muaj teeb meem tswj nws qhov profile.
Yuav zam tau li cas:
Rau cov ntaub ntawv tawv nrog cov cheeb tsam loj, xws li stainless hlau thiab titanium alloys, xaiv cov qauv qhib dua. Qhov chaw pore loj dua txhim kho nti clearance thiab cua sov dissipation.
Rau daim ntawv sib tsoo thiab precision sib tsoo, tus qauv denser tuaj yeem pab tswj lub log profile thiab txhim kho qhov ntev.
Rau loj - cheeb tsam nto sib tsoo, ib qho qhib qauv feem ntau nyiam los txo cov cua sov tsim thiab txo cov thermal deformation. Kev xaiv cov qauv tsim nyog tuaj yeem cuam tshuam rau kev ua haujlwm thiab kev pabcuam lub neej ntawm vitrified sib tsoo log.
Cov Lus Qhia Qhov Kawg Rau Kev Zam Txim Kev Xaiv Qhov yuam kev
Cia siab rau cov kws tshaj lij.
Hloov chaw ntawm kev xaiv raws li kev xav, muab koj tus neeg muag khoom sib tsoo nrog cov ntsiab lus tseem ceeb ntawm koj daim ntawv thov:
Dab tsi yog cov khoom koj sib tsoo?
Koj siv lub tshuab dab tsi?(Lub cev muaj zog, tshuab rigidity, spindle ceev)
Koj ua haujlwm dabtsi?(Rough sib tsoo, tiav kev sib tsoo, daim ntawv sib tsoo)
Koj qhov kev xav tau yog dab tsi?(Productivity, nto tiav, qhov tseeb qhov tseeb)
Lub luag haujlwm sib tsoo lub log xa khoom tuaj yeem pom zoo kom tsim nyog raws li cov xwm txheej no thiab tseem tuaj yeem muab kev sib tw sib tsoo. Tus nqi ntawm kev xaiv txoj cai los ntawm qhov pib tuaj yeem dhau qhov sib txawv me me ntawm tus nqi yuav khoom.
Xaiv txoj cai vitrified sib tsoo log zoo li muab lub tshuab muaj zog rau txoj cai txiav. Khaws tsib yam tseem ceeb no nyob rau hauv siab -abrasive, grit loj, lub log hardness, daim ntawv cog lus, thiab cov qauv- thiab phim lawv rau koj qhov kev sib tsoo tiag tiag. Nrog rau qhov kev qhia tshwj xeeb thiab kev txhawb nqa los ntawm cov kws tshaj lij, koj tuaj yeem zam cov teeb meem xaiv thiab tau txais txiaj ntsig zoo sib xws.
