Izindaba - Indlela Yokuthola Amazinyo Afanele E-Blade Yakho Yokusaha

Emkhakheni wokusika kwezimboni, ama-saw blades avame ukuphambaniswa nezinto ezisetshenziswayo ezivamile. Kodwa-ke, konjiniyela abanolwazi noma abaphathi bokukhiqiza, i-saw blade iyithuluzi eliklanywe kahle. Ikhwalithi yomphumela wokusika ivame ukuncika ekuphambukeni kwama-degree amabili kuya kwamathathu kuphela ku-geometry yephrofayili yamazinyo, okungaholela ekuqhekekeni okukhulu kwe-saw blade noma kuholele endaweni yokusika ebushelelezi njengesibuko.

Kulokhu sihlola izici zomzimba zama-engeli ezinyo le-saw, futhi sichaza ukuthi izimo ezithile zamazinyo zithinta kanjani ukwakheka kokushisa, umthwalo we-chip kanye nekhwalithi yokusika yezinhlobo ezintathu eziyinhloko zezinto zokwakha: izinsimbi zensimbi (ukusika okomile), ukhuni kanye nezinto zokwakha.

Ukwakheka Kwezinyo

Ngaphambi kokuhlaziya izinhlelo zokusebenza ezithile, kumele silinganise amagama ethu maqondana nezilinganiso ezintathu ezibalulekile ze-angular ezichaza ukusebenza kokusika.

I-Rake Angle iyi-engeli yobuso bezinyo uma iqhathaniswa nomugqa oqondile odwetshwe kusukela maphakathi ne-blade kuya esicongweni sezinyo.

Umsebenzi:Inquma "ubukhali" bokusika. Inquma i-engeli yendiza yokugunda—i-engeli lapho izinto ziguquguquka khona futhi zihlukaniswe nomsebenzi.

Umthetho Wesithupha:Ama-engeli aphezulu amahle adinga amandla amancane kodwa akhiqiza ukuqeda okuqinile kanye nokuqina konqenqema oluphansi. Ama-engeli angalungile adinga amandla ehhashi amaningi kodwa anikeza ukulawula okuphezulu kanye namandla onqenqema.

I-Angle Yokucacisa (I-Angle Yokusiza) —β

Lona ucezu oluphezulu lwezinyo olukude nonqenqema oluphambili.

Umsebenzi wayo ukuvimba ama-carbide ukuthi angakhuhliki ezintweni osanda kuzisika.

Nansi indlela yokushintshana:Uma i-engeli iqine kakhulu, izinyo lizophuka futhi lingasekeli, okuholela ekuqhekekeni. Uma lingajulile kakhulu, ukungqubuzana kuzodala ukushisa okweqile, okubangela ukwanda kokushisa futhi ekugcineni kushise ingxenye yokusebenza.

Isikhala Esiqondile (Eceleni)

Le engela inciphisa izinyo kusukela phambili kuya emuva emaceleni.

Inciphisa ukungqubuzana phakathi kwezinhlangothi zamazinyo nezindonga ze-kerf (indawo yokusika). Emisebenzini yokusika okomile lapho kungekho lubricant yokupholisa izinhlangothi zamazinyo, le engela ibaluleke kakhulu ekuvimbeleni ukushisa ukuthi kunganqwabelani.

Izinsimbi Eziyinsimbi (Umshini Owomile Oqoshiwe Obandayo)

Ukugxila: Ukuphathwa Kokushisa kanye Nokumelana Nomthelela

Amasaha abandayo asikiwe omisiwe (afakwe iziqongo ze-cermet noma ze-carbide ezimboziwe) ayisigaba esidinga kakhulu ubuchwepheshe ukuklanywa. Futhi nansi inhloso ephikisanayo: sifuna ukukhiqiza ukushisa, kodwa kufanele sikususe ngokushesha.

Ngesikhathi sokusika okomile, ukushisa kudalwa ukuguquka kwensimbi ngepulasitiki. I-geometry yaleli thuluzi kufanele idlulisele cishe u-80% kuya ku-90% walokho kushisa kuma-chips—ngale ndlela, kokubili i-blade kanye ne-workpiece kuhlala kupholile. Yileyo ndlela kanye isimiso "sokusika okubandayo" esisebenza ngayo.

Ijiyometri ye-"Cold Cut"

Uma sisika insimbi ethambile, sivame ukusebenzisa iphrofayili yokugaya enama-chip amathathu (TCG). Kodwa i-engeli izohluka kuye ngesakhiwo sensimbi.

Izicelo Zodonga Oluncane (Amapayipi, Insimbi Engange, Iziteshi)

I-Angle ye-Rake: Okuhle (+5° kuya ku-+10°)

I-engeli yokuvula: 10° kuya ku-$12°

Ukubonisana:Ukuphakama okuncane kusiza izinyo ukuthi liphume kahle esikiwe ngaphandle kokudonsa i-burr evame ukwakheka ngaphakathi kwepayipi.

Izicelo Eziqinile (Isitokwe Sebha, Ipuleti Eliqinile)

I-Angle ye-Rake: Kusuka ku-zero kuya ku-low Okuhle 0° kuya ku-+3°

Ifiziksi:Uma usika insimbi eqinile, izinyo libambana nezinto zokwakha isikhathi eside, okudala umthwalo oqhubekayo, onomthelela omkhulu. I-engeli ebukhali eqondile ishiya isihloko se-carbide singasekelwa futhi sibuthakathaka.I-angle ye-Zero Rakeiqondisa amandla okusika emuva emzimbeni we-blade, isebenzisa amandla okucindezela e-carbide (aphezulu) kunokuba isebenzise amandla ayo okusika (aphansi).

I-engeli yokuvula: 8°

Ukubonisana:I-engeli ephansi yokuhlukanisa izikhala inezela "inyama" eyengeziwe ngemuva komphetho osezingeni eliphezulu, isebenza njengesinki sokushisa kanye nokusekelwa kwesakhiwo.

Insimbi Engagqwali (Inselele Yokuqinisa Umsebenzi)

I-Angle ye-Rake: 0°kuya ku-+5°
Ukucatshangelwa Okukhethekile:Insimbi engagqwali (njenge-SUS304) ivame "ukusebenza ngokuqinile" uma ikhuhlwa. I-bladekumelesike, ungasheleli. Nakuba i-zero rake inika amandla, sivame ukudinga i-reki enkulu kancaneI-Angle Yokucacisa (12)°)kunokuba kusetshenziswe ensimbini ethambile. Lokhu kuqinisekisa ukuthi ngemva kokusikwa, ingemuva lezinyo alithinti izinto, okuthi "liphinde liphume" kancane ngenxa yokuqina kwalo.

Izicelo Zokusebenza Ngokhuni

Ukugxila: Isiqondiso Sokusanhlamvu Nokunqunywa Kwefayibha

Izinkuni ziyinto e-anisotropic—izakhiwo zazo zomzimba ziyahlukahluka kuye ngokuthi amandla aqondiswa kanjani ngokusanhlamvu. Ngakho-ke, i-geometry ye-saw blade kumele ivumelane nokusanhlamvu.

A. Ukuklebhula (Ukusika Ngokusanhlamvu)

Ukuklebhula empeleni kuwumsebenzi wokusika. Umgomo uwukukhipha imicu emide yefayibha endleleni.
- I-Angle ye-Rake: Okuhle Kakhulu (+20)°kuya ku-+25°)
- Ijiyometri: I-Flat Top Grind (FTG)
- Ifiziksi:I-engeli ephezulu ye-hook isebenza njenge-hand plane, ikhipha izinto ngokushesha. Le engeli enamandla idonsela ukhuni ensikeni. Nakuba lokhu kuvumela amazinga okuphakela okusheshayo kakhulu (okubalulekile kuma-sawmill), ishiya ukuqeda okuqinile.
- Isici Semiphunga:"I-Gullet" (isigodi esiphakathi kwamazinyo) kumele ibe nkulu futhi ijule. Imicu emide yokusanhlamvu idala ama-chips amakhulu; uma i-gullet incane kakhulu, uthuli lwe-sawdust luyacindezeleka, ludale ukungqubuzana futhi lushise ukhuni (kanye ne-blade).
B. Ukusika Okuhlanganisiwe (Ukusika Okuphelele)

Ukunquma ngentambo kudinga ukunqamula imicu eqondile lapho kunqunyiwe. Uma usebenzisa i-ripping blade (FTG) lapha, "izoqhuma" noma iqhekeze ukhuni ohlangothini lokuphuma.
- I-Angle ye-Rake: Okuhle Okumaphakathi (+10)°kuya ku-+15°)
- Ijiyometri: I-Alternate Top Bevel (ATB) noma i-Hi-ATB
- Ifiziksi:Amazinyo ahlungwe ukuze akhe amaphuzu afana nommese ezinhlangothini ezishintshanayo. Ashaya imicu ngakwesobunxele nangakwesokudla kwe-kerfngaphambiukususa izinto eziphakathi. I-engeli yerekhi engezansi (10°uma kuqhathaniswa no-20°) yehlisa ijubane "lokubamba" kwe-blade, okuvumela isenzo sokugunda esibushelelezi esishiya uhlamvu olucwebezelayo.

Okungewona ama-ferrous nama-composites

Ukugxila: Ukuphepha Nokumelana Nokuguguleka

A. I-Aluminium kanye nezinsimbi ezingezona i-ferrous

I-Aluminium ithambile, ithambile, futhi inezinga eliphansi lokuncibilika. Iyaziwa ngokuthi "i-gummy" futhi ivame ukuvimba amazinyo e-blade.
- I-Angle ye-Rake: Okubi (-5)°kuya ku-6°)
- Ijiyometri: I-TCG
- I-Fiziksi Yokuphepha:Uma usebenzisa i-angle ye-hook enhle (njenge-blade yokhuni) ku-aluminium, i-blade "izokhuphukela" ezintweni. Ku-chop saw ngesandla, lokhu kungadonsa ngesihluthulelo isibambo se-saw phansi noma kuphonse umsebenzi.I-Rake Engalungilei-engeli ishintsha i-vector yamandla: isunduza izintokudekusukela ensikeni nangaseceleni kocingo lwangemuva, okuqinisekisa ukuthi ukusika kuphephile futhi kulawulwa.
- Ukugcotshwa:Ngokungafani nokusika okomile kwensimbi, i-aluminium ngokuvamile idinga ukugcotshwa ngenkungu ukuvimbela ama-chips ukuthi angashiselwe emgodini.
B. Izinhlanganisela Zokwakha (Ama-Laminate, i-Melamine, i-Fiber Cement)
- I-Angle ye-Rake: Okubi (-2)°kuya ku--5°)
- Ifiziksi:Izinto ezifana ne-Melamine zinophahla oluqinile, oluqinile njengengilazi phezu kwenhliziyo yebhodi lezinhlayiya elithambile. I-hook enhle iphakamisa izinto phezulu, okwenza ukuthi indawo ephukile iphume.I-Negative Hookucindezela izinto phansi ngesikhathi sokusika, ucindezela ungqimba olungaphezulu futhi uvimbele ukuqhekeka.
- Inothi Lezinto Ezibalulekile:Uma kukhulunywa nge-fibre cement (okuqukethwe kwe-silica okunamandla kakhulu), i-engeli ayibalulekanga kangako kune-tip material.Idayimane yePolycrystalline (PCD)amathiphu ayimpoqo ukuze umuntu aphile isikhathi eside, ngokuvamile anezingqimba ezinhle eziphansi (+5)°) ukuphatha umthwalo osindayo wothuli.
