Disc thiab sib xyaw grinders
Disc grinders tuaj yeem nrog ob lub vertically tso sib tsoo daim hlau los yog nrog ib qho kab rov tav tso sib tsoo phaj.
Duab 2: Ua ke phaj-cov menyuam grinder hom Š1 DB.
Disc sander nrog ib lub phaj yog siv rau angular sanding thiab sanding cov khoom me me nrog qhov chaw me me. Disc grinders nrog ob daim hlau siv tsawg dua.
Rau kev sib tsoo tiaj tus, profiled thiab cov ntsiab lus nrog nkhaus nto, sib xyaw grinders thiab profile grinders yog siv. Ib hom kev sib xyaw ua ke yog Š1 DB phaj-cov menyuam hom (daim duab 2), uas muaj cov phaj ntsug thiab cov menyuam.
Ib daim ntaub xuab zeb yog rub mus rau lub tshuab phaj thiab lub tog raj kheej (bobbin). Lub phaj thiab cov menyuam yog tsau rau ntawm lub shafts ntawm lub tshuab hluav taws xob. Los ntawm txoj kev tshwj xeeb eccentric mechanism, cov menyuam txav mus rau qhov sib npaug mus rau lub ncej, rov qab thiab tawm, nrog lub amplitude ntawm 0 rau 40 mm. Ntawm lub phaj ntsug, ib lub rooj yog muab tso rau cov khoom lossis cov khoom me me uas yuav tsum tau xuab zeb; lub rooj kuj tuaj yeem muab tso rau ntawm lub kaum sab xis rau lub phaj sib tsoo.

Profile thiab cylindrical grinders
Profile grinders yog siv rau kev sib tsoo profiled ntsiab. Lawv muaj ib tug spindle nrog lub taub hau ua hauj lwm nyob rau hauv uas inserts nrog sanding ntaub yog tsau nyob ib ncig ntawm lub perimeter. Thaum lub sij hawm ua hauj lwm, cov inserts elastically adhere lub sanding daim ntaub mus rau lub profile ntawm lub caij.
Cylindrical grinders tau muab faib ua ib lub tog raj kheej, ob-lub tog raj kheej, peb lub tog raj kheej thiab rau-lub tog raj kheej, nrog rau phau ntawv thiab cov tshuab hloov pauv. Kev taw qhia txav yog ua rau ntawm ib lub tog raj kheej grinders, uas feem ntau yog siv rau cov ntsiab lus nrog nkhaus, xws li arched profiles.
Multi-lub tog raj kheej grinders nrog txhua yam hloov pauv yog siv rau kev sib tsoo boards, veneers thiab thav ntawv. Qhov kev txav tuaj yeem ua tau los ntawm kev siv cov menyuam los yog roj hmab conveyor siv. Kev tshem tawm siv cov menyuam yog siv thaum xuab zeb veneers, thiab tshem tawm los ntawm txoj siv conveyor thaum sanding panels, qhov rooj thiab thav ntawv.
Lub tog raj kheej ntawm cov tshuab xuab zeb yog cov raj steel nrog cov khoom siv rau kev sib npaug thiab tensioning cov ntaub xuab zeb. Lawv tuaj yeem ua tag nrho lossis txiav. Cov ntaub xuab zeb yog qhov txhab ntawm tag nrho lub tog raj kheej nyob rau hauv ib tug kauv thiab tsau rau pem hauv ntej ntawm lub tog raj kheej nrog ib tug tshwj xeeb zawm cuab yeej. Ntawm cov cylinders txiav, cov ntaub xuab zeb yog clamped nyob rau hauv lub qhov nrog lub tog raj kheej bearing.
Tag nrho cov thooj voos kheej kheej yog tsim nyog rau zawm cov ntaub xuab zeb thiab yooj yim sib npaug. Lawv tuaj yeem nyob rau saum toj lossis hauv qab lub caij yog hauv av, nrog rau txoj haujlwm sab saud raug suav tias yog qhov zoo dua. Ntxiv nrog rau cov lus tsa suab, cov thooj voos kheej kheej kuj txav mus rau qhov sib npaug rau lawv cov axis, kwv yees100ntawm ob zaug strokes ib feeb thaum taug kev los ntawm10 mm. Lub tog raj kheej tuaj yeem pib los ntawm kev siv lub tshuab xa hluav taws xob lossis lub tshuab hluav taws xob ua ke.
Sanders nrog tsuas yog sab sauv lossis tsuas yog qhov chaw qis ntawm lub tog raj kheej xav tau cov ntsiab lus kom dhau ob zaug thaum sib tsoo ob sab. Rau-lub tog raj kheej grinders nrog rau sab sauv thiab qis lub tog raj kheej txoj hauj lwm zom ob sab ntawm lub caij nyob rau hauv ib tug pass.

Raws li cov khoom siv uas cov nplej txuas nrog rau lub substrate, cov ntaub xuab zeb yog tsim rau cov xuab zeb qhuav thiab ntub dej. Cov ntaub ntawv khi siv rau cov xuab zeb qhuav yog xav tau, thiab cov nplaum hluavtaws rau cov xuab zeb ntub. Sanding ntaub nrog dej-resistant hluavtaws adhesives yog siv rau sanding nitrocellulose varnishes nrog muab tshuaj txhuam los yog lwm yam ntaub ntawv sanding.
