  • Amazinyo engeziwe:Iphumela ekuqedeni okushelelayo, okucolekile kodwa isivinini sokusika esihamba kancane. Ilungele izinto ezinezindonga ezincane noma ezithambile.
  • Amazinyo Ambalwa:Ivumela ukusika okusheshayo, okunolaka ngokuphuma okungcono kwe-chip. Ilungele izinto eziwugqinsi, eziqinile.
• I-Bore (Arbor Hole):Imbobo emaphakathi kufanele ifane kahle nokuphotha komshini wamasaha ukuze kuqinisekiswe ukulingana okuvikelekile nokuzungezisayo okuzinzile.

4. Isayensi Yokukhetha: Isicelo se-Blade nepharamitha

Ukufanisa kahle i-blade kanye nemingcele yokusika kundaba yinto eyodwa ebaluleke kakhulu ekuzuzeni imiphumela emihle.

(1) Ukukhetha Ukucaciswa Kweblade Engakwesokudla

Ukukhethwa kobubanzi be-blade nokubala kwamazinyo kuxhumene ngokuqondile nobubanzi bezinto ezibonakalayo kanye nemodeli yomshini wokusaha. Ukufanisa okungalungile kuholela ekungasebenzi kahle, ikhwalithi yokusika engalungile, kanye nokulimala okungenzeka kwe-blade noma umshini.

Okulandelayo kunikeza umhlahlandlela wesicelo ojwayelekile osuselwe kumazinga womkhakha:

Uhlelo Lokusebenza:Ukusebenzisa i-blade encane kakhulu ku-workpiece kuzocindezela umshini ne-blade, kuyilapho i-blade enkulu ingasebenzi kahle futhi ingaholela ekudlidlizeni. Uhlobo lomshini luhambisana namandla, ukuqina, namandla adingekayo ukuze ushayele kahle usayizi weblade onikeziwe.

(2) Ukuthuthukisa Amapharamitha Wokusika

Ukukhetha okulungileisivinini sokujikeleza (RPM)futhiisilinganiso sokuphakelayokubalulekile ekwandiseni impilo yamathuluzi kanye nokuzuza ukusika kwekhwalithi. Lawa mapharamitha ancike ngokuphelele ezintweni ezisikwayo. Izinto eziqinile, ezilumayo zidinga isivinini esiphansi kanye namazinga okuphakela aphansi.

Ithebula elilandelayo, elisuselwa kudatha yemboni yama-blades angu-285mm no-360mm, lihlinzeka ngereferensiIsivinini SomugqafuthiOkuphakelayo Izinyo Ngalinye.

Izimiso Eziyinhloko:

• Isivinini Somugqa (Ijubane Lobuso):Lokhu kuhlala njalo okuhlotshaniswa ne-RPM nobubanzi be-blade. Ukuze i-blade enkulu igcine isivinini esifanayo somugqa, i-RPM yayo kufanele ibe ngaphansi. Yingakho i-360mm blade inezincomo eziphansi ze-RPM.
• Okuphakelayo Izinyo Ngalinye:Lokhu kulinganisa inani lempahla ekhishwa izinyo ngalinye. Okwezinto eziqinile njengensimbi yamathuluzi (SKD11), izinga lokuphakelayo eliphansi kakhulu libalulekile ukuvimbela amathiphu e-carbide ukuthi angaphuki ngaphansi kwengcindezi ephezulu. Ngensimbi enekhabhoni ephansi ethambile (Q235), izinga eliphezulu lokuphakela lingasetshenziswa ukukhulisa ukusebenza kahle kokusika.
• Insimbi engagqwali:Le nto "i-gummy" kanye ne-conductor empofu yokushisa. Izivinini zomugqa ezihamba kancane ziyadingeka ukuze kuvinjelwe ukuqina komsebenzi kanye nokwanda kokushisa okudlulele onqenqemeni lokusika, okungahle kwehlise ngokushesha i-blade.

5. Ukuphatha Nokunakekela: Ukumaka, Ukupakisha, kanye Nesitoreji

Ukuphila isikhathi eside nokusebenza kwensingo yesaha nakho kuncike ekuphathweni nasekugcinweni kwayo, okufanele kuhambisane namazinga afana ne-GB/T 191.

• Ukumaka:I-blade ngayinye kufanele imakwe ngokucacile ngezici zayo ezibalulekile: ubukhulu (ububanzi x ukujiya x bore), inani lamazinyo, umkhiqizi, kanye ne-RPM ephephile ephezulu. Lokhu kuqinisekisa ukuhlonza okulungile nokusetshenziswa okuphephile.
• Ukupakishwa:Ama-blades kufanele ahlanganiswe ngokuvikelekile ukuze kuvikelwe amazinyo e-carbide antekenteke ekushayeni ngesikhathi sokuthutha. Lokhu kuvame ukuhlanganisa amabhokisi aqinile, izihlukanisi ze-blade, nezingubo zokuvikela noma izembozo zamazinyo.
• Isitoreji:Ukugcinwa ngendlela efanele kubalulekile ukuze kuvinjwe umonakalo nokugqwala.
  • Imvelo:Gcina ama-blade endaweni ehlanzekile, eyomile, nelawulwa isimo sezulu (izinga lokushisa elinconywayo: 5-35°C, umswakama ohlobene:<75%).
  • Ukuma:Ama-blades kufanele ahlale egcinwe ngokuvundlile (flat) noma alengiswe ngokuqondile kuma-rack afanelekile. Ungalokothi ubeke ama-blade phezu kwamanye, njengoba lokhu kungabangela ukungqubuzana nokulimala kwamazinyo.
  • Ukuvikelwa:Gcina ama-blade kude nezinto ezonakalisayo kanye nemithombo yokushisa eqondile.

Isiphetho: Ikusasa Lokusika Okubandayo Okujwayelekile

Ukuqaliswa kwamazinga okusebenza aphelele kuyisinyathelo esibalulekile esiya phambili embonini yensimbi. Ngokuhlinzeka ngohlaka olucacile, lwesayensi lokuklama, ukukhethwa, kanye nokusetshenziswa kwama-saha ayindilinga esike ensimbi abandayo, le mihlahlandlela inika amabhizinisi amandla okuthuthukisa ukusika ukusebenza kahle, ukuthuthukisa ikhwalithi yomkhiqizo, nokunciphisa izindleko zokusebenza.
