Kampani yogulitsa zida zomangira yomwe yakhala ikupereka mayankho a makina omangira kwa zaka 30.
Kusankha tsamba la diamondi sikuti kungosankha kukula koyenera ndikuyembekeza kuti sokalo likukhululukirani. Tsambalo liyenera kufanana ndi zinthu zomwe zili mkati mwake, sokalo, kuya kwa kudula ndi momwe ntchito ilili. Konkire, phula ndi slabs zolimba zonse zingawoneke ngati "zinthu zolimba" patali, koma kwa tsamba la diamondi zimachita mosiyana kwambiri.
Lamulo loyambira ndi losavuta: zipangizo zolimba nthawi zambiri zimafuna mgwirizano wofewa, pomwe zipangizo zofewa komanso zokwawa zimafuna mgwirizano wolimba. Norton Abrasives akufotokoza za kusankha kwa chikole cha tsamba la diamondi ndi mfundo yofanana yotsutsana: zomangira zolimba zimayenderana ndi zinthu zofewa zokwawa monga phula, pomwe zomangira zofewa zimayenderana ndi konkire wolimba. Poyamba zimamveka ngati zachikale, koma zimakhala zomveka mukakumbukira kuti chomangira chachitsulocho chiyenera kuwonongeka pa liwiro loyenera kuti chiwonetse diamondi zatsopano.
Lamulo lachangu: sankhani tsamba potengera zinthu kaye, kenako tsimikizirani mtundu wa chigwirizano, kapangidwe ka magawo, kukula kwa macheka, kuya kwa kudula ndi kugwiritsa ntchito konyowa kapena kouma.

Gwiritsani ntchito tchati ichi ngati fyuluta yoyamba. Ngati mukufuna kufananiza mozama pakati pa zinthu zoyendera panjira, werengani bukuli pa Kusankha tsamba la konkire motsutsana ndi la phula Kusankha tsamba lomaliza kumadalirabe kukula kwa tsamba, kukula kwa arbor, mphamvu ya macheka, kuya kwa kudula, RPM rating komanso ngati madzi alipo.
Konkire yokonzedwa bwino ndi yolimba, makamaka ikakhala ndi aggregate yokhuthala. Imafooketsa ma diamondi omwe amawonekera, kotero chigwirizanocho chiyenera kuvala mokwanira kuti chiwonetse ma diamondi atsopano odulidwa. Ma guides a diamondi nthawi zambiri amagwiritsa ntchito konkire pa 3,000 psi kapena pansi ngati chinthu chofewa ndipo konkire pa 6,000 psi kapena pamwamba ngati chinthu cholimba. Zimenezi zimapatsa mainjiniya ndi ogula malo abwino oyambira asanayang'ane mtundu wa aggregate ndi chowonjezera.
Asphalt ndi yofewa kuposa konkire wokonzedwa, koma imakhala yolimba kwambiri. Mchenga ndi zinthu zina zomwe zili mu phula zimatha kudya pakati pa tsamba ngati tsamba lolakwika lagwiritsidwa ntchito. Ichi ndichifukwa chake tsamba la diamondi la phula nthawi zambiri limagwiritsa ntchito chomangira cholimba komanso chitetezo chochepetsedwa. M'mawu osavuta, phula si "konkire yosavuta." Ndi chopukusira tsamba chomwe chimavala zovala zogwirira ntchito.
Ma slab olimbikitsidwa amawonjezera vuto lina: chitsulo. Tsamba la diamondi la konkire yokhala ndi mipiringidzo yokhazikika limafuna zigawo zolimba, kupanikizika kosalekeza kwa chakudya komanso kuziziritsa bwino. Kudula konyowa nthawi zambiri kumakhala chisankho chanzeru chifukwa kukhudzana ndi chitsulo kumapangitsa kutentha mwachangu.
| Mtundu wa Chigwirizano | Zabwino Kwambiri | Ngati Zagwiritsidwa Ntchito Molakwika |
|---|---|---|
| Chigwirizano chofewa | Konkire yolimba, konkire yolimba, konkire yolimbikitsidwa | Amavala mofulumira kwambiri mu phula |
| Chigwirizano chapakati | Ntchito za konkriti ndi ntchito zosakanikirana | Zovomerezeka, koma nthawi zonse si zabwino |
| Chigwirizano cholimba | Asphalt, konkire wobiriwira, chipika chokwezera | Kodi ingagwiritsidwe ntchito kukongoletsa konkire yolimba |
Chophatikizana chilinso chofunikira. Malangizo ena osankha masamba amagawa chophatikizana chachikulu kuposa mainchesi 3/4 ngati chophatikizana chachikulu, pomwe chophatikizana pansi pa mainchesi 3/8 chimakhala chosavuta kudula koma chingagwire tsamba mwachangu. Ichi ndichifukwa chake ma slabs awiri okhala ndi mphamvu yofanana yokakamiza amatha kudula mosiyana. Konkireti ili ndi nthabwala, ndipo nthawi zambiri imabisa mkati mwa chophatikizanacho.
Pa konkire yokonzedwa bwino, yambani ndi tsamba la diamondi logawika m'magulu. Ngati konkire ndi yolimba kapena tsamba layamba kukhuthala, pitani ku chomangira chofewa. Ngati konkire ndi yofewa komanso yokwawa, pitani ku chomangira cholimba. Kuti mudziwe zida zina zokhudzana nazo, mutha kuwonanso tsamba la simenti lodula tsamba.
Kusankha tsamba la konkire loti lizigwirizana ndi chochekacho. Mwachitsanzo, Mafotokozedwe a Husqvarna K 770 Lembani tsamba la mainchesi 14 , kuya kwakukulu kwa kudula kwa mainchesi 5 , kutulutsa kwa 5 hp ndi liwiro lalikulu la peripheral la 18,000 fpm . Manambala amenewo ndi chikumbutso chakuti kusankha tsamba sikukhudza zinthu zokha. Kukula kwa m'mimba mwake, kukula kwa arbor ndi liwiro lake ziyenera kugwirizana ndi makinawo.
Podula phula, gwiritsani ntchito tsamba la diamondi la phula lopangidwa ndi phula. Liyenera kukhala ndi chigwirizano cholimba, malo abwino otsetsereka komanso chitetezo chodulidwa. Norton akunena kuti kudula pansi kungayambitse kutayika kwa gawo, ndipo amalimbikitsa chitetezo chodulidwa pansi kapena kuchuluka kwa madzi komwe zinthu zokwawa zimagunda pakati pa chitsulo.
Tsamba lapadera la phula limasonyeza momwe zida zimenezi zilili zapadera. CMT imalemba tsamba la phula la 300 mm yokhala ndi gawo lotetezedwa ndi 8 mm losadulidwa bwino , chibowo cha 20 mm ndi liwiro lapamwamba la 6,400 rpm , ndipo imawonetsa kuti si yoyenera konkire kapena konkire yolimbikitsidwa. Pa ntchito zoyendera pamisewu ya phula, phatikizani tsamba ndi chodulira choyenera, monga chodulira chodulira konkire wa petulo chodulira phula ndi konkire .
Pa konkire yolimba, gwiritsani ntchito tsamba loyesedwa kuti ligwirizane ndi rebar. Chigwirizano chofewa mpaka chapakati chimathandiza tsamba kuti lipitirire kudula konkire yolimba, pomwe kapangidwe kamphamvu kamathandiza kuti lipulumuke kutentha ndi kugundana ndi chitsulo chikaonekera. Magawo olumikizidwa ndi laser nthawi zambiri amakondedwa podula kwambiri chifukwa kulumikizana kwa gawo kumakhala kolimba pakakhala zovuta.
Musakakamize tsamba likafika pa rebar. Sungani chakudya chili chokhazikika, gwiritsani ntchito madzi ngati n'kotheka ndipo pewani kupotoza soka lomwe lili mkati mwa chodulidwacho. Ngati tsambalo layamba kusuta, sokalo layamba kudumphadumpha, kapena wogwiritsa ntchito ayamba kukambirana ndi makinawo, imani ndikuyang'ana momwe makinawo alili.
Kudula konyowa sikungokhudza moyo wa tsamba lokha. Malangizo a silika yomanga ya OSHA imayika mulingo wa mphamvu ya silika yopumira pa 25 μg/m³ ndi malire ololedwa owonekera pa 50 μg/m³ , zonse ziwiri ngati avareji yolemera nthawi ya maola 8. Izi zimapangitsa kudula konyowa kukhala chisankho chowongolera fumbi komanso chisankho choziziritsa.
Kudula kouma n'kothandiza pa kudula kwachidule komanso ntchito yokonza, koma kokha ndi tsamba loyenera kugwiritsidwa ntchito louma. Musagwiritse ntchito tsamba lonyowa lokha louma. Si njira yofulumira yopititsira kutentha kwambiri, kuphimba ndi tsamba lomwe mwadzidzidzi limakhala chitsulo chodula kwambiri. Kuti muyerekezere bwino, werengani kudula konkire konyowa poyerekeza ndi konkire youma .
Tsamba labwino pa soka lolakwika silipereka zotsatira zabwino. Musanadule, tsimikizirani kukula kwa tsamba, kukula kwa arbor, RPM yayikulu, kuya kwa kudula, madzi ndi mphamvu ya soka. Ngati ntchitoyo ikuphatikizapo kudula misewu yayitali, kukonza misewu kapena kukonza ngalande, chitsogozo ichi chili pa momwe mungasankhire chodulira msewu choyenera cha konkire ndi phula ndiye sitepe yotsatira yabwino.
Kwa makontrakitala kuyerekeza makina, chitsogozo chachikulu cha odulira konkire ndi makina odulira misewu imapereka zambiri zokhudza mtundu wa makina, kuya kwa kudula ndi ntchito yoyenda pansi. Ngati mukufuna mawonekedwe ochulukirapo a momwe mungagwiritsire ntchito, nkhani yokhudza ubwino wa macheka a msewu pa kukonza konkire, phula ndi msewu ndi njira yothandiza yopezera chidziwitso chamkati.
Cholakwika choyamba ndi kugwiritsa ntchito tsamba limodzi pa konkire, phula ndi slabs zolimbikitsidwa. Chachiwiri ndi kunyalanyaza kuuma kwa bond. Chachitatu ndi kudzudzula soka pamene vuto lenileni ndi kunyezimira kwa tsamba, RPM yolakwika, kuzizira koyipa kapena kugwirizana kolakwika kwa zinthu.
Ngati tsamba la diamondi lasiya kudula, yang'anani mgwirizano, zinthu, liwiro la macheka ndi madzi musanakankhire mwamphamvu. Tsamba labwino liyenera kudula ndi mphamvu yokhazikika. Ngati muyenera kulimbana ndi macheka, tsambalo mwina likukuuzani zinazake. Pa vuto lenilenilo, gwiritsani ntchito malangizo awa pa Kuphimba tsamba la diamondi ndi chifukwa chake tsamba limasiya kudula .
Gwiritsani ntchito tchati chosankha tsamba la diamondi kuti muchepetse kusankha, kenako tsimikizirani zinthu zinayi: zipangizo, mgwirizano, machesi odulira ndi njira yodulira. Pa konkire, ganizirani za mphamvu ndi chivundikiro. Pa phula, ganizirani za kusweka ndi chitetezo chochepetsedwa. Pa slabs zolimba, ganizirani za chitsulo, kutentha ndi kuzizira.
Tsamba lolondola silimangodula mwachangu. Limayenda mozizira, limakhala nthawi yayitali, limachepetsa nthawi yogwira ntchito ndipo limapangitsa wogwiritsa ntchito kuwoneka ngati adakonzekera chilichonse kuyambira kale.
