Hauv kev lag luam zeb zeb,ultra-thin multi hlau saw tshuabs yog cov khoom siv tseem ceeb rau kev ua haujlwm zoo ntawm cov tawv thiab nkig slabs xws li marble, granite, thiab quartz. Txhim kho kev txiav ceev yog qhov tseem ceeb ntawm kev lag luam xav tau; Txawm li cas los xij, cov yam ntxwv ntawm pob zeb-Mohs hardness ntawm 5-7, hmoov av siab thaum lub sij hawm ua, thiab susceptibility rau chipping thiab breakage- ua kom yooj yim nce kev khiav hauj lwm tsis muaj kev cuam tshuam ntawm kev ua tau zoo thiab zoo. Kab lus no, raws li lub tswv yim ntawm kev hloov kho kom raug thiab kev ua kom zoo dua qub, tsim cov kev daws teeb meem nrawm uas sib npaug txiav qhov tseeb, xaim pom lub neej, thiab kev ua haujlwm ntawm plaub qhov ntev:pob zeb diamond hlau saw, cov txheej txheem tsis, cov qauv khoom siv, thiab kev saib xyuas txhua hnub.
I. Txhim khu kev ua tau zoo ntawm pob zeb diamond hlau saws
Kev ua tau zoo ntawm cov pob zeb diamond hlau pom ncaj qha txiav txim siab lub siab ntawm kev txiav ceev. Lub hauv paus ntawm optimization yog nyob rau hauv adapting rau cov yam ntxwv ntawm lub pob zeb kom ua tiav ceev txiav thiab ruaj khov sib tsoo.
Pob zeb diamond, nrog Mohs hardness ntawm 10, yog ib qho zoo tagnrho rau kev txiav pob zeb. Kev xaiv meej raws li hom slab yog qhov tseem ceeb:
☆ Txiav marble (nruab nrab- nyuaj, nkig): Siv 80-120 mesh electroplated pob zeb diamond hlau. Lub txheej ruaj khov tuav lub abrasive, suppressing chipping thiab nce txiav efficiency li ntawm 30%.
☆ Txiav granite (siab-hardness, hnav-} tiv taus): Siv 60-80 mesh resin-bonded pob zeb diamond hlau. Nws tus kheej zoo heev -ntxhiab cov khoom ncua sij hawm abrasive dulling, thiab ua ke nrog ntau- txheej txheej txheej ua kom abrasive bonding ceev los ntawm 40%, tus naj npawb ntawm cov hniav txiav zoo ib lub sij hawm tau nce zuj zus, ua rau muaj kev nce ceev heev.
Cov hlau pom lub cev siv siab - carbon steel hlau nrog zinc -nickel alloy txheej. Nrog lub zog tensile Ntau dua lossis sib npaug ntawm 2800MPa, nws tuaj yeem tiv taus siab - ceev txiav cov khoom, txo qhov kev pheej hmoo ntawm cov hlau tawg. Cov txheej zoo tiv thaiv plua plav abrasion, txuas ntxiv lub pob zeb diamond hlau lub neej los ntawm 20% thiab txo qis sijhawm rau kev hloov hlau.
Qhov zoo tshaj plaws hlau txoj kab uas hla yog 0.3-0.8 hli kom tsis txhob khoov thiab deflection teeb meem tshwm sim nrog hlau diameters<0.3 mm, balancing cutting efficiency and tension stability to ensure simultaneous high-speed operation of multiple wires.
II. Optimizing Core Process Parameters kom txo tau qhov tsis kam, noj, thiab txhim kho kev ua haujlwm
Cov txheej txheem parameter optimization aims kom txo tau tej yam kuj thiab tsis tsim nyog losses, ua kom tiav ib tug sib npaug ntawm ceev thiab stability.
1. Optimized linear ceev
☆ Marble / Limestone: 12-18 m / s, kev txhim kho ntawm 40% -80% piv rau cov tsoos 8-10 m / s;
☆ Granite / Basalt: 8-12 m / s, kev txhim kho ntawm 33% - 50% piv rau cov tsoos 6-8 m / s.
Ib tug 0.3-thib ob tsis yog ntxiv thaum lub sij hawm xaim hloov pauv, txo cov kab ceev mus rau 5 m / s kom txo tau qhov cuam tshuam thiab xyuas kom tsis tu ncua kev kub ceev txiav.
2. Pub tus nqi sib tw
☆Brittle Stone (Marble): 0.8–1.5 mm/min, nrog ib tug elastic feed mechanism uas yuav txo tau ceev raws li ntsib tsis kam thiab tsub kom ceev yam tsis muaj kev tiv thaiv, ua rau ib tug 50% nce nyob rau hauv efficiency piv rau ib tug tsis tu ncua - ceev pub.
☆ Pob zeb tawv (Granite): 1.5-2.5 mm / min, nce kev noj zaub mov zoo los ntawm 50% -67%, thaum txhim kho nti tshem tawm kom tsis txhob muaj plua plav thiab ua kom muaj zog ntxiv.
3. Txiav kua thiab nti tshem tawm qhov system
Siv dej-raws li kev txiav cov kua, txiav tsis kam yog txo los ntawm kwv yees li 30%. Ib tug polyethylene glycol nti tshem tawm tus neeg sawv cev yog ntxiv kom tsis txhob muaj cov sludge buildup txuam nrog roj -raws li txiav kua.
Ua ke nrog lub siab -siab annular spray, inclined nti sau trough, thiab tsis zoo siab plua plav collect system, tshem tawm plua plav sai sai, tiv thaiv abrasive clogging thiab ua kom ruaj khov thiab ruaj khov siab - ceev txiav.
III. Txhim kho cov cuab yeej hloov kho kom ntseeg tau siab -Kev nrawm txiav raug thiab ruaj khov
1. Optimized Tensioning thiab Guide System
Lub kaw lus kaw servo tas li tensioning yog saws, nrog rau qhov tseeb nro ntawm ± 0.2N. Qhov no cais cov plua plav cuam tshuam, kom ntseeg tau tias tsis sib xws ntawm ntau cov xov hlau thiab tiv thaiv kev quab yuam txawv txav ntawm ib lub xaim los ntawm kev rub tawm tag nrho cov txiaj ntsig.
Kev tsis sib haum yog teem raws li pob zeb hom: marble 12–15N, granite 15–18N, ua tau raws li qhov yuav tsum tau muaj ntawm siab - txiav ceev.
Cov log tsheb yog tsim los ntawm cov khoom siv ceramic nrog cov kabmob kaw, muab 8 npaug ntawm kev hnav tsis kam ntawm cov hlau qhia log, nrog radial runout Tsawg dua lossis sib npaug li 0.01mm. Qhov no zoo txo cov hlau pom kev co thiab kev khiav hauj lwm, kom ntseeg tau tias txiav raug.
2. Txhim kho lub rooj ua haujlwm kho thiab cov qauv
Lub tshuab nqus tsev ob lub tshuab nqus tsev adsorption (suction force Ntau dua lossis sib npaug ntawm 0.08MPa) + kev siv tshuab clamping yog siv los tiv thaiv cov ntaub ntawv xa tawm thaum lub sij hawm siab - txiav ceev, txo cov nqi rov ua haujlwm.
Lub rooj ua haujlwm siv lub hauv paus hlau cam khwb cia nrog silicon nitride hnav- tiv thaiv txheej, sib txuas ua haujlwm siab thiab tsis tshua muaj kev sib txhuam. Qhov no shortens clamping pab lub sij hawm thiab indirectly txhim kho tag nrho cov tshuab ua hauj lwm efficiency.
IV. Standardize Kev Kho Txhua Hnub kom txo qis kev poob qis
Kev ua haujlwm tsis tu ncua ntawm cov cuab yeej siv yog qhov tseem ceeb rau kev txhim kho kev ua haujlwm tag nrho. Kev saib xyuas tus qauv tuaj yeem tiv thaiv tag nrho cov khoom lag luam poob qis vim kev poob qis los ntawm kev ua haujlwm tsis zoo.
Txhua lub lis piam kuaj xyuas cov pob zeb diamond hlau abrasive shedding tus nqi; Yog tias nws siab tshaj 25%, cov hlau yuav tsum tau hloov tam sim ntawd los tiv thaiv kev poob qis los ntawm qhov tsis txaus abrasive thiab tsis txhob poob siab ntawm kev txiav ntawm 50%.
Thaum lub txiav quab yuam dheev nce los ntawm 12N mus rau 18N, nws yog suav tias yog abrasive dulling, thiab cov hlau pom yuav tsum tau hloov tam sim ntawd.
Tsis tu ncua ntxuav cov plua plav los ntawm cov khoom tseem ceeb xws li lub tensioning mechanism thiab coj lub log nrog 0.6MPa siab - rab phom cua siab, thiab yaug lub rooj ua haujlwm thiab cov chips sau lub thawv nrog dej huv kom tsis txhob muaj plua plav thiab txhaws.
Kev txiav cov kua dej yuav tsum dhau peb- theem pom: 100μm hlau mesh los lim cov khoom loj → 20μm daim ntawv lim kom lim cov plua plav nruab nrab → 5μm ceramic membrane kom lim cov plua plav zoo, ua kom muaj kev huv huv tsawg dua lossis sib npaug li 5mg / L, tiv thaiv nozzle clogging, thiab ua kom muaj kev sib tw siab 5.
