Choj saws muaj nyob rau hauv kev ua lag luam poob rau hauv ob pawg: cov pa infrared phau ntawv choj saws (nrog zaus converter + tswj vaj huam sib luag pob qhov rooj) thiab CNC 4/5-axis choj saws (ceev tswj ntawm touchscreen systems). Ob leeg cia siab rau spindle zaus converter los kho lub cev muaj zog ceev. Tsis txhob tshaj qhov siab tshaj plaws RPM cim rau ntawm lub saw saw.
I. Peb Txoj Cai Tswjhwm Ceev (Muab sib txawv tshuab qauv)
Hom 1: Pa Infrared Choj Pom ( Sab Nraud Potentiometer Knob, Feem ntau)
Kev Npaj Kev Nyab Xeeb: Kaw lub tshuab, tua lub spindle, thiab tos kom txog thaum lub saw hniav nres tag ua ntej hloov.
Nrhiav qhov spindle ceev hloov pob qhov rooj ntawm lub console ua haujlwm.
Ua kom me me zoo -tu, sim- txiav tom qab txhua qhov kev hloov kho ± 100 RPM.
Lub pob qhov rooj tsuas yog muab kev hloov kho ib ntus xwb. Lub Hoobkas- teem siab tshaj plaws ceev txwv yog xauv rau hauv lub zaus converter; tig lub pob qhov rooj rau txhua txoj kev yuav tsis pub tshaj qhov txwv ntawm lub cev muaj zog lossis saw hniav.
Kuaj-Txoj Cai Txiav: Txiav qhov chaw du yam tsis muaj ntug chipping, kev co hnyav, thiab dej txias txaus.
Hom 2: CNC Choj Pom
Cov kauj ruam ua haujlwm
Fais fab rau thiab hloov mus rau phau ntawv hom; tsis txhob kho ceev thaum lub sij hawm txiav tsis siv neeg. (Kev khiav hauj lwm sib txawv me ntsis los ntawm lub tshuab hom thiab qauv)
Txoj Kev 1: Spindle Interface → Spindle Speed S → Input target RPM thiab paub meej tias kev ua kom tiav.
Txoj Kev 2: Spindle multiplier knob ntawm lub vaj huam sib luag / multiplier slider ntawm qhov screen . 100% stands for the base setting; tiag -lub sij hawm ceev tuaj yeem ua tau zoo-tuned hauv 50%-120%.
Kev Ua Haujlwm: Hloov kho tus nqi S hauv G-code (xws li S2400, S3000), txuag qhov program thiab khiav nws.
Speed Limit Lock: Teem lub siab tshaj plaws spindle ceev nyob rau hauv qhov system tsis tiv thaiv overspeed los ntawm misoperation.
Hom 3: Internal Parameter hloov ntawm zaus Converter
Tsuas yog cov kws tshaj lij hluav taws xob tsim nyog tau tso cai los ua cov ntawv qhia zaub mov no; Nws yog qhov tsis tsim nyog rau kev ua haujlwm txiav txhua hnub.
Txiav tawm lub hwj chim thiab qhib lub txee tswj hluav taws xob kom nkag mus rau qhov hloov pauv zaus zaus (7.5/11/15kW raws li cov ntsiab lus tseem ceeb).
Cov yam ntxwv tseem ceeb (yuav tsum phim lub npe lub npe): P01: Rated lub cev muaj zog, voltage, tam sim no, 50Hz, ntsuas ceev
Upper Limit Frequency P01.06: Tswj qhov siab tshaj plaws rotating ceev. Standard teeb rau 350mm saw hniav: 60-65Hz
Acceleration & Deceleration Lub sij hawm: 1-2 vib nas this kom tsis txhob tripping tshwm sim los ntawm startup/shutdown cuam tshuam
Zaus-rau-Kev hloov pauv ceev (Universal rau 350mm Pom Hniav) 50Hz ≈ 2400RPM; 60Hz ≈ 2880RPM; 65Hz ≈ 3120RPM
Txuag cov kev txwv, lub zog rau thiab sim khiav. Kev ua haujlwm ib txwm tsis muaj suab nrov lossis lub tswb ceeb toom qhia tias kev teeb tsa tiav.
II. Standard Reference Speeds rau cov khoom siv pob zeb sib txawv (350mm / 14-nti Standard Pom Hniav)
Txoj Cai Kev Nyab Xeeb Tseem Ceeb: Nyob rau hauv tsis muaj qhov xwm txheej tshaj qhov siab tshaj plaws RPM stamped ntawm lub saw hniav. Overspeeding yuav ua rau cov hniav tawg thiab raug mob hnyav rau tus kheej.
Marble / Limestone (Soft Pob zeb): 2400-2800RPM Kev kub ceev heev kub hnyiab ntu thiab darkens slab nto; Tsis tshua muaj ceev ua rau ntug chipping thiab hnyav txiav kuj.
Granite / Grey Pob Zeb (Lub Pob Zeb Nruab Nrab Nruab Nrab): 2800-3200RPM Kev ua haujlwm zoo tshaj plaws xa cov chaw txiav tiaj tus thiab sib npaug ntu hnav.
Quartz Pob zeb / Sintered Pob zeb / Ultra-Hard Quartz: 1800-2200RPM Cov ntaub ntawv no muaj qhov tawv tawv heev. Kev kub ceev ua rau kub dhau heev uas melts resin thiab accelerates ntu puas. Tsawg ceev ntxiv nrog cov dej txias ntau yog yuav tsum tau ua.
Nyias Slabs (tsawg dua los yog sib npaug rau 10mm): Ua kom nrawm ntawm 200RPM raws li qhov txwv sab saud ntawm cov khoom siv; Thick Slabs (Ntau dua lossis sib npaug rau 50mm): Txo ceev los ntawm 200-400RPM.
III. Visual Judgement Criteria for Speed Adjustment
Cov cim qhia txog kev kub ceev heev (txo kom nrawm tam sim)
Darkened txiav kerf, burnt npoo, whitened annealed txiav ntu
Lub tshuab khaus vibration thiab hnyav suab nrov
Hnyav dawb pos huab los ntawm dej txias thiab kub kub nce
Ceev ceev saw hniav hnav thiab pob zeb diamond particle shedding
Cov cim qhia ntawm Tsawg Tshaj Lij Tshaj (Nyob nrawm nrawm)
Hnyav txiav tsis kam, tshuab stalling thiab qeeb pub mis
Loj kaum chipping thiab jagged ntxhib npoo ntawm pob zeb nto
Lub cev muaj zog overload thiab nquag overcurrent tswb ntawm lub zaus converter
IV. Txoj Cai Tswj Kev Nyab Xeeb yuav tsum tau ua
Nco ntsoov nres lub tshuab ua ntej hloov ceev; ceev tes kom deb ntawm cov saw saws.
Khiav cov saws tshiab ntawm qhov qis qis rau 3-feeb so hauv lub sijhawm ua ntej nce mus rau kev ua haujlwm ceev.
Siab - txiav ceev yog txwv tsis pub thaum cov dej txias tsis txaus.
Kev nrawm yuav tsum tau hloov kho thaum hloov cov saw hniav ntawm cov kab sib txawv: cov hniav loj dua tso cai qis tshaj qhov ceev. Piv txwv li: Max ceev Tsawg dua los yog sib npaug rau 2600RPM rau 400mm cov hniav; mus txog 3300RPM rau 300mm hniav.
Ntev- lub sijhawm ua haujlwm qis dua 1500RPM impairs spindle motor heat dissipation thiab tej zaum yuav hlawv windings. Tsis txhob ncua sij hawm qis - ceev txiav kom ntau li ntau tau.
V. Common Fault Troubleshooting
Kev nrawm tseem tsis hloov pauv tom qab tig lub pob qhov rooj: Qhov kev txwv siab tshaj ntawm qhov hloov pauv zaus raug kaw. Tus kws kho hluav taws xob yuav tsum tau kho qhov siab tshaj plaws ntawm cov khoom siv sab hauv.
Kev mus ncig hauv Circuit Court tam sim ntawd tom qab nce ceev: luv luv acceleration / deceleration lub sij hawm, mismatched lub cev muaj zog tsis, los yog hnyav load vim dej txias tsis txaus.
Kev ceev cov tswv yim ntawm CNC touchscreen tsis ua haujlwm: Multiplier xauv ntawm 0%, spindle pab kom hloov mus, lossis khawm ceev ceev.
Kev vibration ntawm qis ceev: Hnav spindle bearings, deformed flange phaj los yog warped saw hniav. Ua ntej qhov kev tshuaj xyuas txhua yam ua ntej kho qhov nrawm.
