Yintoni i-Dry-Cutting for Metal?

Ukuqonda iSetyhula iisarha zeMetal

Njengoko igama lisitsho, isarha yentsimbi esetyhula isebenzisa iincakuba ezimile okwedisk ukusika izinto. Olu hlobo lwesarha lulungele ukusika isinyithi ngenxa yokuba uyilo lwayo luvumela ukuba ihlale ihambisa izicucu ezichanekileyo. Ukongezelela, ukunyakaza kwesetyhula kwe-blade kudala isenzo esiqhubekayo sokusika, okwenza kube lula ukunqumla isinyithi esine-ferrous kunye ne-non-ferrous.I-Dry-cutting yindlela yokusika isinyithi ngaphandle kokusebenzisa ulwelo olupholileyo. Esikhundleni sokusebenzisa ulwelo ukunciphisa ubushushu kunye nokukhuhlana, ukusika okomileyo kuxhomekeke kwiincakuba ezenziwe okanye ezigqunywe ngaphakathi, izinto ezinokumelana nobushushu kunye nokukhuhlana kwesinyithi kudala. Ngokuqhelekileyo, ii-diamond blades zisetyenziselwa ukusika okomileyo ngenxa yobunzima kunye nokuqina.

I-circular saw blades esetyenziselwa enye i-metal sawing iya kuvelisa ubushushu obuninzi xa usika intsimbi ejikelezayo, i-aluminium kunye nezinye izinto ezikhethekileyo; kodwa ngamanye amaxesha kuyimfuneko ukugcina i-workpiece esarha kunye ne-blade epholileyo. Kule meko, okhethekileyo I-circular saw blade ye-blade yezinto eziphathekayo igqiba i-sawing, eyi-cold saw.

Imfihlelo yesakhono esibandayo sokukwazi ukugcina i-workpiece kunye ne-blade yabona ipholile yintloko ekhethekileyo yokusika: intloko ye-cermet cutter.

Iintloko ze-Cermet cutter zigcina iimpawu ze-ceramics ezifana nobunzima obuphezulu, amandla aphezulu, ukumelana nokunxiba, ukumelana nobushushu obuphezulu, ukuxhathisa kwe-oxidation kunye nokuzinza kweekhemikhali, kunye nokuqina kwentsimbi kunye neplastiki. I-Cermet ineenzuzo zombini zetsimbi kunye ne-ceramic. Inobunzima obuphantsi, ubunzima obuphezulu, ukuxhathisa ukunxiba kunye nokuhamba kakuhle kwe-thermal. Ayiyi kuba brittle ngenxa yokupholisa okanye ukufudumeza ngequbuliso. Ngexesha lokusika, i-serration ye-ceramic cutter head iya kuqhuba ubushushu kwiichips, ngaloo ndlela igcina i-saw blade kunye nezinto zokusika zipholile.

Izinto eziluncedo zokusarha ezibandayo

Iisarha ezibandayo zingasetyenziselwa ukusika iimilo ezininzi ezahlukeneyo, kubandakanywa iintonga, iityhubhu, kunye ne-extrusions. Iisarha ezizenzekelayo, ezivaliweyo ezijikelezayo ezibandayo zisebenza kakuhle kwiiprojekthi zemveliso kunye neeprojekthi eziphindaphindiweyo apho ukunyamezela kunye nokugqiba kubalulekile. Aba matshini banikezela ngesantya se-blade eguquguqukayo kunye namazinga okutya alungelelanisiweyo kwimveliso enesantya esiphezulu kunye ne-burr-free, ii-cuts ezichanekileyo. Izibonelelo ezongezelelweyo ziquka imveliso encinci ye-burr, iintlantsi ezimbalwa, ukuguga okuncinci kwaye akukho luthuli.

Inkqubo yokusarha ebandayo iyakwazi ukugqithisa okuphezulu kwiintsimbi ezinkulu kunye ezinzima - kwiimeko ezithile, nokuba ziqinile njenge-± 0.005" (0.127 mm) ukunyamezela. Iisarha ezibandayo zingasetyenziselwa ukunqunyulwa kweentsimbi zombini kunye nezingadibanisi, kunye nokusikwa okuthe tye kunye ne-angled. Ngokomzekelo, amabakala aqhelekileyo entsimbi abolekisa kwi-sawing ebandayo, kwaye anokunqunyulwa ngokukhawuleza ngaphandle kokuvelisa ubushushu obuninzi kunye nokuxubana.

Ezinye iiDownsides ukuya kwiisarha ezibandayo

Nangona kunjalo, ukubanda okubandayo akulunganga kubude obungaphantsi kwe-0.125" (3.175 mm). Ukongeza, le ndlela inokuvelisa i-burrs enzima. Ngokukodwa, ngumba apho une-ODs phantsi kwe-0.125 "(3.175 mm) kunye nakwii-ID ezincinci, apho ityhubhu iya kuvalwa yi-burr eveliswa yi-cold saw.

Enye into engathandekiyo kwiisarha ezibandayo kukuba ukuqina kwenza iincakuba zeesarha zibe brittle kwaye zixhomekeke kumothuko. Naliphi na inani lokungcangcazela - umzekelo, ukusuka ekubambeni okunganelanga kwenxalenye okanye izinga lokutya elingalunganga - linokonakalisa ngokulula amazinyo esarha. Ukongeza, iisarha ezibandayo zihlala zibangela ukulahleka okukhulu kwekerf, okuguqulela kwimveliso elahlekileyo kunye neendleko eziphezulu.
Nangona i-sawing ebandayo ingasetyenziselwa ukusika ezininzi i-alloys ene-ferrous kunye ne-non-ferrous, ayikhuthazwa kwiintsimbi ezinzima kakhulu-ngokukodwa, ezo zinzima kune-saw ngokwayo. Kwaye ngelixa iisarha ezibandayo zinokwenza ukusika okuhlanganisiweyo, kunokukwenza kuphela ngeengxenye ezincinci zedayamitha kunye nokulungiswa okukhethekileyo kuyafuneka.

Iintsimbi ezilukhuni zokusika ngokukhawuleza

I-cold sawing isebenzisa i-blade ejikelezayo ukususa izinto ngelixa uhambisa ubushushu obuveliswayo kwiitshiphu ezenziwe nge-saw blade. Isarha ebandayo isebenzisa nokuba yintsimbi eqinileyo enesantya esiphezulu (HSS) okanye iblade ye-tungsten carbide-tipped (TCT) ejika kwi-RPMs esezantsi.
Ngokuchaseneyo negama, ii-HSS blades azifane zisetyenziswe ngesantya esiphezulu. Kunoko, uphawu lwabo oluphambili lubunzima, olubanika ukuchasana okuphezulu nokushisa kunye nokugqoka. Iibhleyidi ze-TCT zibiza kakhulu kodwa zikwanzima kakhulu kwaye ziyakwazi ukusebenza kumaqondo obushushu aphezulu nangaphezulu kune-HSS. Oku kuvumela ii-TCT ii-saw blades ukuba zisebenze ngesantya esikhawulezayo kune-HSS blades, ukunciphisa kakhulu ixesha lokusika.

Ukusika ngokukhawuleza ngaphandle kokuvelisa ubushushu obugqithisileyo kunye nokukhuhlana, iileyidi zoomatshini ababandayo zixhathisa ukunxitywa kwangaphambi kwexesha ezinokuchaphazela ukugqitywa kweengxenye ezisikiweyo. Ukongeza, zombini iindidi zeencakuba zinokuphinda zilolwe kwaye zinokusetyenziswa amaxesha amaninzi ngaphambi kokuba zilahlwe. Obu bomi beblade bude bunceda ukwenza isarha ebandayo ibe yindlela eneendleko zokusikwa ngesantya esiphezulu kunye nokugqitywa komgangatho ophezulu.

Iimpazamo eziqhelekileyo zokuPhepha xa i-Metal-Cutting Dry

Njengoko usebenzisa i-blade enzima kunentsimbi, ukusika okomileyo kunokuba nzima kwizixhobo zakho. Ukuze uthintele umonakalo okanye iingozi ngelixa usika isinyithi, nazi iimpazamo eziqhelekileyo ekufuneka uziqwalasele:

Isantya seBlade esingalunganga: Xa usomile-ukusika ngesinyithi, kubalulekile ukunikela ingqalelo kwisantya se-blade. Ukuba i-blade yakho ihamba ngokukhawuleza, inokubangela ukuba isinyithi sigobe okanye siguquke kwaye siphule i-blade yakho. Kwelinye icala, ukuba ihamba kancinci kakhulu, ubushushu buya kukhula kwisarha yakho kwaye buyonakalise.

UkuBamba ngokungafanelekanga:Qinisekisa ukuba ucinezela ngokukhuselekileyo nayiphi na into yesinyithi oyisikayo. Izinto ezihambayo ziyingozi kwaye zinokubangela ingozi enkulu.

Xa usebenzisa nawuphi na umatshini wokusarha obandayo, kubalulekile ukukhetha iteyitshi efanelekileyo yezinyo kwizinto ezisikwayo.

Ukukhetha eyona pitch yezinyo kwiblade yakho ebandayo kuya kuxhomekeka:

* Ukuqina kwezinto

* Ubungakanani becandelo

* Ubukhulu bodonga

Amacandelo aqinileyo afuna iincakuba ezinepitshi yamazinyo erhabaxa, ngelixa iityhubhu ezinodonga olucekethekileyo okanye iimilo ezinamacandelwana amancinci anqamlezayo zifuna iincakuba ezinesandi esicolekileyo. Ukuba unamazinyo amaninzi kwizinto eziphathekayo ngexesha elinye, umphumo uya kukrazula kunokususwa kwe-chip. Oku kukhokelela ekunyukeni okuphezulu koxinzelelo lokucheba.

Kwelinye icala, xa usikwa iindonga ezinzima okanye izinto eziqinileyo usebenzisa i-pitch yamazinyo entle kakhulu, iitshiphusi ziya kujikeleza ngaphakathi kumgudu. Ekubeni i-pitches enamazinyo amancinci anemibhobho encinci, i-chips eziqokelelweyo ziya kudlula umthamo we-gullets kwaye zicinezele kwiindonga ze-workpieces ezibangela ukuba ii-chips jamming kwaye zibambeke. I-saw blade ebandayo iya kuqala ukwenza ngathi ayisiki, kodwa oko kungenxa yokuba ayikwazi ukuluma ngeegullets ezixineneyo. Ukuba unyanzelisa i-blade, uya kuba neengxaki zokusika kunye noxinzelelo olubaluleke kakhulu lokucheba, olunokuthi ekugqibeleni lukhokelele ekuqhekekeni kweblade yakho ebandayo.

Nceda uqaphele ukuba ngeli xesha ukukhetha ibala lokuwisa izinyo elililo kwisicelo sakho kubaluleke kakhulu, asiyiyo kuphela into emisela eyona blade isarha ebandayo kwisicelo sakho. Ngokufana nezinye izixhobo, ukusebenza kakuhle kwesarha ebandayo kunye nobomi obude buxhomekeke ubukhulu becala kumgangatho wesitshixo. amacandelo afana nencakuba. I-HERO ithengisa ezona blades zibanda kakhulu kuba sisebenzisa oomatshini bobuchwephesha abenziwe eJamani ukwenza iimveliso zethu. Iincakuba zethu ziya kukunceda usike isinyithi kwiiprojekthi ezingenakubalwa.Singakuvuyela ukuncedisa ngefowuni!
