jewelers, motorists, manufacturers ntawm cov khoom muag feem ntau ntsib tib lo lus nug: yuav ua li cas kom zoo nkauj, ci ntsa iab ntawm ib yam khoom? rab riam los cawm. Nws yog dab tsi? Qhov no yog txheej txheem uas nyuaj ntawm ib feem yog ntxuav thiab machined.

Lub ntsiab ntawm txoj kev

Tumbling yog sib xyaw ntawm cov khoom siv abrasive thiab cov khoom ua haujlwm hauv lub thawv. Kev sib cuam tshuam ntawm cov khoom tshwm sim nyob rau hauv ob txoj kev txav:

• rotary (rotating);
• vibrating.

Tubmbling lub cev, vim kev sib txhuam, ntxuav qhov chaw rau qhov xav tau gloss lossis roughness los ntawm kev tshem tawm cov microparticles ntawm nws. Cov txheej txheem tuaj yeem siv sijhawm li 4 txog 80 teev.

Qhov kom zoo dua ntawm txoj kev yog qhov ua tau ntawm cov chaw ua haujlwm nrog cov duab tsis zoo thiab qhov ntau thiab tsawg. Qhov tsis zoo suav nroglub impossibility ntawm kev ua nyias-walled qhov chaw.

Nws tsim nyog sau cia tias kev tu ncua yog ib qho txheej txheem ntawm kev khiav hauv qhov chaw, uas tuaj yeem ua tau ob txoj hauv kev:

• dry;
• wet.

Txoj kev qhuav siv tshwj xeeb muab tshuaj txhuam, hmoov thiab cov khoom sib tsoo. Hauv txoj kev ntub dej, cov kua dej ua haujlwm, coagulants, thiab tumbling daws tau ntxiv rau lub nruas. Kev ntub dej feem ntau yog siv ua ntej siv ntau hom txheej: galvanized, enameled, thiab lwm yam.

Qhov twg muaj feem

Teb cov lus nug dab tsi yog tumbling, nws yuav tsum tau muab sau tseg tias ntxiv rau polishing, nws tso cai rau koj tshem tawm flash, burrs, xeb, nplai ntawm qhov chaw. Kev xaiv cov khoom siv abrasive xav tau yuav tso cai rau koj muab qhov xav tau roughness thiab specular nto. Cov ntawv thov:

• instrumentation;
• mechanical engineering;
• construction;
• jewellery.

Tsis tas li ntawd, tumbling yog siv rau cov khoom siv hauv tsev (riam, hniav, hniav), tsheb rims, cov khoom siv ntuj (pob zeb), cov khoom yas.

Mineral tumbling yog ua kom cov pob zeb zoo nkauj zoo nkauj, ci ntsa iab, zom cov npoo ntse, tsim cov kab du, tshem cov plaque thiab chips. Cov khoom zoo li no tuaj yeem raug txiav lossis siv los ua talismans, amulets. Tumbling yog ua rau pob zeb xws li:

• citrine;
• aquamarine;
• amethyst;
• shungite;
• jasper;
• quartz;
• obsidian;
• malachite;
• agate;
• carnelian;
• rhinestone;
• hematite;
• aventurine.

khoom siv

Rau tumbling, tshwj xeeb tumbling tshuab yog siv, uas yog tus qauv los ntawm GOST 10548-74. Qhov chaw ua haujlwm hauv ntu ntu yog lub voj voog lossis lub prism.

1. Hom khoom siv yooj yim tshaj plaws yog lub nruas nruas. Kev sib hloov yog nqa tawm los ntawm kev siv lub tshuab hluav taws xob, kev ua haujlwm tshwm sim vim kev sib xyaw dawb ntawm cov abrasive thiab qhov chaw. Siv rau cov khoom siv yooj yim, muaj kev ua haujlwm tsawg thiab kev ua haujlwm zoo, kev tswj xyuas qhov muag tsis pom nrog txoj kev no.



2. Cov khoom siv vibration - feem ntau niaj hnub no - yog chav da dej qhib nrog kev sib txuas nrog kev vibration, uas ua rau nws oscillatory txav. Abrasive lub cev pib siv micro-tshuaj lom rau ntawm qhov chaw, tshem tawm ib txheej nyias nyias. Cov cuab yeej ntawm hom no tso cai rau koj los ua ib txhij ua cov khoom loj ntawm qhov chaw.
3. Rotor khoom - yog lub nruas ruaj khov, nyob rau hauv qis qis uas muaj cov hniav tig. Qhov tsis zoo suav nrog kev hnav sai ntawm sab hauv ntawm lub nruas, tsis muaj peev xwm ua cov khoom loj. Qhov kom zoo dua ntawm txoj kev no yog kev tsim khoom siab thiab zoo ntawm qhov tshwm sim.
4. Spindle cov cuab yeej - ib feem yog tsau rau hauv spindle, txo qis rau hauv lub thawv nrog cov khoom siv abrasive thiab pib tig. Kev siv qeeb, unidirectional lossis lwm yam kev ua tshwj xeeb yog ua tau. Siv nyob rau hauv high-tech industries: aircraft tsim, kho mob prosthetics.

Tumbling khoom

Nws tuaj yeem hais tias tumbling yog xws li kev sib tsoo, zawv zawg thiab microcutting ntawm qhov chaw ntawm qhov chaw nrog cov khoom siv abrasive, uas qhov kawg tshwm sim yuav nyob ntawm seb hom thiab cov khoom siv ntawm lub cev lapping. Raws li cov cuab yeej stripping siv:

• pebbles;
• abrasive grain;
• granular abrasive;
• pob kws macerate;
• nutshell;
• steel polished spheres;
• ceramic thiab volcanic abrasive;
• quartz xuab zeb;
• limestone;
• ntoo cev.

Phase tumbling feem ntau yog siv, thaum muaj qhov txo qis hauv qhov loj ntawm cov khoom abrasive. Cov duab ntawm lub cev lapping tuaj yeem sib txawv:

• tetrahedron;
• parallelepiped;
• cube;
• ball;
• cylinder;
• cone;
• prism.

Qee zaum nws tuaj yeem siv sijhawm ntau thiab cov peev txheej los ua kom tiav dua li nws ua ib feem.
