Kuyini Ukusika Okungashisi Kwensimbi?

Ukuqonda Ama-Circular Metal Saws

Njengoba igama lisho, isaha lensimbi eliyindilinga lisebenzisa ama-blade amise okwediski ukusika izinto. Lolu hlobo lwesaha lufanelekela ukusika insimbi ngoba ukwakheka kwalo kuyivumela ukuthi ikwazi ukusika ngokunembile njalo. Ngaphezu kwalokho, ukunyakaza okujikelezayo kwe-blade kudala isenzo sokusika esiqhubekayo, okwenza ukuthi ikwazi ukusika izinsimbi zensimbi nezingezona ezensimbi. Ukusika okomile kuyindlela yokusika insimbi ngaphandle kokusebenzisa uketshezi olupholile. Esikhundleni sokusebenzisa uketshezi ukunciphisa ukushisa nokungqubuzana, ukusika okomile kuncike kuma-blade enziwe noma ambozwe, into engamelana nokushisa nokungqubuzana okwenziwa yinsimbi. Ngokuvamile, ama-blade edayimane asetshenziselwa ukusika okomile ngenxa yobunzima nokuqina kwawo.

Ama-blade esaha ajikelezayo asetshenziselwa ukusaha insimbi azokhiqiza ukushisa okukhulu lapho kusikwa insimbi eyindilinga, i-aluminium nezinye izinto ezikhethekile; kodwa ngezinye izikhathi kuyadingeka ukugcina umsebenzi osikiwe kanye ne-blade yesaha kupholile. Kulokhu, i-blade yesaha ejikelezayo ye-blade yezinto ezibonakalayo iqedela ukusaha, okuyi-cold saw.

Imfihlo yekhono lokusika ngokubandayo lokugcina umsebenzi kanye ne-saw blade kupholile yikhanda lokusika elikhethekile: ikhanda lokusika le-cermet.

Amakhanda okusika e-Cermet agcina izici ze-ceramics njengokuqina okuphezulu, amandla aphezulu, ukumelana nokuguguleka, ukumelana nokushisa okuphezulu, ukumelana nokushiswa kwe-oxidation kanye nokuqina kwamakhemikhali, futhi anokuqina okuhle kwensimbi kanye ne-plasticity. I-Cermet inezinzuzo zensimbi kanye ne-ceramic. Inobukhulu obuphansi, ubunzima obukhulu, ukumelana nokuguguleka kanye nokuqhuba kahle kokushisa. Ngeke iphuke ngenxa yokupholisa noma ukushisa okungazelelwe. Ngesikhathi sokusika, ukugoba kwekhanda lokusika le-ceramic kuzohambisa ukushisa kuma-chips, ngaleyo ndlela kugcine i-saw blade kanye nezinto zokusika zipholile.

Izinzuzo Zokusika Okubandayo

Ama-cold saw angasetshenziswa ukusika izimo eziningi ezahlukene, kufaka phakathi izinduku, amashubhu, kanye ne-extrusions. Ama-cold saw azenzakalelayo, avaliwe asebenza kahle ekukhiqizeni kanye namaphrojekthi aphindaphindwayo lapho ukubekezelelana nokuqeda kubalulekile khona. Le mishini inikeza isivinini se-blade esiguquguqukayo kanye namazinga okuphakelayo alungisekayo ukuze kukhiqizwe ngesivinini esikhulu kanye nokusika okungenama-burr, okunembile. Ama-cold saw ayakwazi ukugaya ama-alloy amaningi e-ferrous kanye ne-non-ferrous. Izinzuzo ezengeziwe zifaka phakathi ukukhiqizwa kwe-burr okuncane, izinhlansi ezimbalwa, ukushintsha kombala okuncane kanye nokungabi nothuli.

Inqubo yokusaha okubandayo iyakwazi ukukhiqiza kakhulu izinsimbi ezinkulu nezisindayo — ezimweni ezithile, ngisho noma ziqine njengo-±0.005” (0.127 mm). Amasaha abandayo angasetshenziswa ekunqumeni izinsimbi zensimbi neze-non-ferrous, kanye nokusika okuqondile nokuqondile. Isibonelo, amazinga avamile ensimbi avumela ukusaha okubandayo, futhi angasikwa ngokushesha ngaphandle kokudala ukushisa okukhulu nokungqubuzana.

Ezinye Izinzuzo Zokusaha Okubandayo

Kodwa-ke, ukusaha okubandayo akulungele ubude obungaphansi kuka-0.125” (3.175 mm). Ngaphezu kwalokho, le ndlela ingakhiqiza ama-burrs asindayo. Ngokukhethekile, kuyinkinga lapho une-ODs engaphansi kuka-0.125” (3.175 mm) kanye nama-ID amancane kakhulu, lapho ithubhu lizovalwa yi-burr ekhiqizwa yi-cold saw.

Enye inkinga ngama-cold saw ukuthi ubulukhuni benza ama-saw blades aqhekeke futhi ashaqeke. Noma yikuphi ukudlidliza — isibonelo, ngenxa yokungabambeki kahle kwengxenye noma izinga lokuphakelwa elingalungile — kungalimaza kalula amazinyo e-saw. Ngaphezu kwalokho, ama-cold saw ngokuvamile abangela ukulahlekelwa okukhulu kwe-kerf, okuholela ekulahlekelweni komkhiqizo kanye nezindleko eziphakeme.
Nakuba ukusaha okubandayo kungasetshenziswa ukusika iningi lama-alloy e-ferrous kanye ne-non-ferrous, akukhuthazwa ngezinsimbi eziqinile kakhulu — ikakhulukazi lezo eziqinile kunesaha ngokwalo. Futhi yize ama-cold saw engenza ukusika okuhlanganisiwe, angakwenza lokho kuphela ngezingxenye ezincane kakhulu zobubanzi futhi kudingeka i-fixturing ekhethekile.

Ama-Hard Blades Okusika Okusheshayo

Ukusaha okubandayo kusebenzisa i-blade eyindilinga ukususa izinto ngenkathi kudluliselwa ukushisa okukhiqizwayo kuma-chips adalwe yi-blade yokusaha. I-cold saw isebenzisa i-blade eqinile yensimbi enesivinini esikhulu (i-HSS) noma i-tungsten carbide-tipped (i-TCT) ephenduka ngama-RPM aphansi.
Ngokuphambene negama, ama-HSS blades awavamile ukusetshenziswa ngesivinini esikhulu kakhulu. Esikhundleni salokho, isici sawo esiyinhloko ubulukhuni, obuwenza amelane nokushisa nokuguguleka okuphezulu. Ama-TCT blades ayabiza kakhulu kodwa futhi aqinile kakhulu futhi ayakwazi ukusebenza emazingeni okushisa aphezulu kakhulu kune-HSS. Lokhu kuvumela ama-TCT saw blades ukuthi asebenze ngesivinini esisheshayo kune-HSS blades, okunciphisa kakhulu isikhathi sokusika.

Ukusika ngokushesha ngaphandle kokudala ukushisa okukhulu nokungqubuzana, ama-blade omshini wokusaha abandayo amelana nokuguguleka kwangaphambi kwesikhathi okungathinta ukuqeda kwezingxenye ezisikiwe. Ngaphezu kwalokho, zombili izinhlobo zama-blade zingalolwa kabusha futhi zingasetshenziswa izikhathi eziningi ngaphambi kokuba zilahlwe. Lokhu kuphila isikhathi eside kwama-blade kusiza ukwenza ukusaha okubandayo kube yindlela engabizi kakhulu yokusika ngesivinini esikhulu kanye nokuqeda kwekhwalithi ephezulu.

Amaphutha Avamile Okufanele Uwagweme Lapho Usika Insimbi Omile

Njengoba usebenzisa i-blade eqinile kunensimbi, ukusika okomile kungaba nzima kumathuluzi akho. Ukuze ugweme umonakalo noma izingozi ngenkathi usika insimbi, nanka amaphutha avamile okufanele uwaqaphele:

Isivinini Se-Blade Esingalungile: Uma usika insimbi, kubalulekile ukunaka isivinini se-blade. Uma i-blade yakho ihamba ngokushesha kakhulu, ingabangela ukuthi insimbi igobe noma igobe futhi iphule i-blade yakho. Ngakolunye uhlangothi, uma ihamba kancane kakhulu, ukushisa kuzokwanda kusaha lakho futhi kungase kulimaze.

Ukubopha Okungalungile: Qinisekisa ukuthi ubamba ngokuqinile noma iyiphi into yensimbi oyisikayo. Izinto ezinyakazayo ziyingozi futhi zingadala umonakalo omkhulu.

Uma usebenzisa noma yimuphi umshini wokusika obandayo, kubalulekile ukukhetha i-toothpitch efanele yezinto ezisikiwe.

Ukukhetha i-toothpitch efanele ye-blade yakho ye-cold saw kuzoncika ku:

* Ubulukhuni bezinto ezibonakalayo

* Usayizi wesigaba

* Ubukhulu bodonga

Izingxenye eziqinile zidinga ama-blade ane-tooth pitch eqinile, kuyilapho amashubhu noma izimo zodonga oluncane ezinezingxenyana ezincane zidinga ama-blade ane-pitch encane. Uma unamazinyo amaningi kakhulu entweni ngesikhathi esisodwa, umphumela uzoba ukudabuka kunokususwa kwama-chip. Lokhu kuholela ekwandeni okukhulu kokucindezeleka kokucheba.

Ngakolunye uhlangothi, uma usika izindonga ezisindayo noma izinto eziqinile usebenzisa i-tooth pitch encane kakhulu, ama-chips azojikeleza ngaphakathi kwe-gullet. Njengoba ama-pitch amancane anama-gullet amancane, ama-chips aqoqiwe azodlula umthamo wama-gullet futhi acindezele ezindongeni zezinto zokusebenza okuholela ekutheni ama-chips aqhekeke futhi abhajwe. I-cold saw blade izoqala ukusebenza sengathi ayisiki, kodwa lokho kungenxa yokuthi ayikwazi ukuluma ngama-gullet avinjiwe. Uma uphoqa i-blade ukuthi idlule, uzobhekana nokusikwa okubi kanye nokucindezeleka okukhulu kokucheba, okuzogcina kuholele ekuphukeni kwe-cold saw blade yakho.

Sicela uqaphele ukuthi nakuba ukukhetha i-toothpitch efanele yokufaka kwakho kubaluleke kakhulu, akuyona yodwa into enquma i-cold saw blade engcono kakhulu yokufaka kwakho.Njengoba kunjalo nakwamanye amathuluzi, ukusebenza kahle kwe-cold saw kanye nobude bayo kuncike kakhulu kwikhwalithi yezingxenye ezibalulekile njenge-blade. I-HERO ithengisa ama-cold saw blade amahle kakhulu njengoba sisebenzisa imishini yobuchwepheshe eyenziwe eJalimane ukudala imikhiqizo yethu. Ama-blade ethu azokusiza ukusika insimbi kumaphrojekthi amaningi. Singajabula ukukusiza ngocingo!
