Hauv qab no yog cov lus qhia ntxaws ntxaws los siv 12.9-QibTorx ScrewsThiab coj tus xov tooj CNC Toolholder Screws (M2.5-M8), nthuav tawm Tiered los ntawm kev thov yuav tsum tau ua.
I. Cov yam ntxwv ntawm12.9-Qib Torx Screws
Cov Khoom Siv thiab Lub Zog: Qib 12.9 yog cov tawv tawv tawv hlau nrog lub zog tensile ntawm ntau dua los yog sib npaug rau 1220 MPA. Nws yog qhov haum rau cov kev siv hluav taws xob siab, cov ntawv thov siab tshaj plaws (xws li cov cuab yeej ruaj khov hauv cov cuab yeej cnc).
Rust-ntawv pov thawj: Cov kev kho mob xws li muaj cov xim dub, Nickel plating, lossis dacromet txheej. Zam cov kua qaub thiab alkali corrosion.
Torque rhiab: ultra-siab lub zog ua rau nce ntxiv brittleness, uas yuav tsum tau nruj raws li lub zog kom tiv thaiv tawg.
Ii. Cov kauj ruam tseem ceeb
Kev npaj lub qhov
Lub xov uas koj phim cov ntsia hlau tsis taus (qib 6H), thiab lub qhov ntug yuav tsum tau ua kom tsis txhob muaj burrs.
Ntxuav lub qhov xov (siv cua compressed lossis cov kais dej siab kom tshem tawm cov khib nyiab).
Ntsia Hlau Installation
Los ntawm txhais tes ua kom nruj: manually zawm cov xov 2-3 zaug kom ntseeg tau smoothness. Tsis txhob yuam cov ntsia hlau hauv.
Zawm nyob rau hauv cov kauj ruam: Screws M6 thiab loj dua xav tau nce lub zog hauv 2-3 nce ntxiv.
Lubrication thiab kev sib txhuam sib txhuam: Thov molybdenum disulfide grease nyob rau hauv cov kev mob siab kom txo cov kev txhuamricient los ntawm 20% -30%.
Torque tswj: Siv preset torque wrench nrog a ± 5% kev kam.
Dynamic loads (xws li milling) yuav tsum muaj ntxiv 10% -15% kev tiv thaiv kev tiv thaiv kev nyab xeeb.
IV. Raug tsis ua tiav thiab kev tiv thaiv
Xov slippage: tshwm sim los ntawm threaded lub qhov, uas tuaj yeem kho tau los ntawm kev hloov cov xov ntxig nrog ib cov xov hlau ntxig.
Lub taub hau tawg:
Cause: Ntau lub zog los yog hnav cov hexagon ntsaws (t-wrenen mismatch).
Kev daws: Hloov nrog cov hexagon ntswj tsim rau kev cuam tshuam cov ciaj ntswj (nrog rau qhov hluav taws xob ntxiv).
Txo: Nyob rau hauv kev corating mob, nws raug nquahu kom ntxiv lub caij nplooj ntoo hlav thiab xov rau kev tiv thaiv ob npaug.
V. kev pom zoo
Kev soj ntsuam tsis tu ncua: rov ua kom lub zog ntawm Screws M6 thiab loj dua tom qab txhua 8 teev ntawm machining. Hloov yog lub zog txo qis dua 15%.
Cov kev tsis lees paub tsis lees paub: Xov deformation ntau dua los yog sib npaug rau 5% lossis pom indentation ntawm cov xov.
Cia: Ib tug zuj zus uas tau ntim los tiv thaiv kev cuam tshuam, ua kom cov av noo<60% to avoid hydrogen embrittlement.
IV. Raug tsis ua tiav thiab kev tiv thaiv
Slippage: tshwm sim los ntawm threaded lub qhov xoob (feem ntau hauv M2.5-M3 Screws). Hloov nrog hlau hlau ntxig ntxig rau kev kho.
Lub taub hau tawg:
Cause: ntau dhau torque lossis hnav xov yothing (t-wrenen mismatch).
Kev daws: Hloov nrog lub taub hau xov rau lub taub hau tsim rau kev cuam tshuam cov ciaj ntswj (nrog rau qhov hluav taws xob ntxiv).
Txo: Nyob rau hauv kev corating mob, nws raug nquahu kom ntxiv lub caij nplooj ntoo hlav thiab xov rau kev tiv thaiv ob npaug.
V. kev pom zoo
Kev soj ntsuam tsis tu ncua: Rov ua kom cov ntsia hlau loj dua M6 txhua 8 teev tom qab machining (hloov yog tias poob ntau dua 15%).
Cov kev tsis lees paub tsis lees paub: Xov deformation ntau dua los yog sib npaug rau 5% lossis pom indentation ntawm cov xov.
Cia: Ib tug zuj zus uas tau ntim los tiv thaiv kev cuam tshuam, ua kom cov av noo<60% to avoid hydrogen embrittlement.
Through standardized operation and regular maintenance, Grade 12.9 screws can significantly improve the rigidity and lifespan of CNC tool systems, making them particularly suitable for high-speed machining (>8000 rpm). Nws raug nquahu kom tsim ib lub khawm khawm "tseem ceeb ceev nrawm hloov cav" kom taug qab cov kev siv tsheb mus.
Cov tub ntxhais ntawm cov cuab yeej ntawm cov cuab yeej no nyob hauv kev sib koom ua ke ntawm cov ntaub ntawv, thiab CNC tsim nyog kom ua tiav cov khoom siv high-tshuab, ua rau nws haum rau high-ntim kev tsim khoom.
