  • Mano Enanso:Zotsatira zake zimakhala zofewa, zomaliza koma zocheperako. Zabwino kwa zida zokhala ndi mipanda yopyapyala kapena zosalimba.
  • Mano Ochepa:Imalola kudulidwa mwachangu, mwamakani kwambiri ndikuchotsa bwino kwa chip. Zabwino pazida zolimba, zolimba.
• Bore (bowo la Arbor):Bowo lapakati liyenera kufananiza ndendende ndi spindle ya makina ocheka kuti zitsimikizire kuti zikuyenda bwino komanso kuzungulira kokhazikika.

4. Sayansi Yosankha: Blade ndi Parameter Application

Kufananiza bwino tsamba ndi magawo odulira kuzinthu ndi chinthu chimodzi chofunikira kwambiri kuti tipeze zotsatira zabwino.

(1) Kusankha Mafotokozedwe a Tsamba Loyenera

Kusankhidwa kwa masamba ndi kuchuluka kwa dzino kumalumikizidwa mwachindunji ndi mainchesi azinthu ndi mtundu wa makina ocheka. Kuphatikizika kosayenera kumabweretsa kusachita bwino, kudulidwa bwino, komanso kuwonongeka kwa tsamba kapena makina.

Zotsatirazi zimapereka chiwongolero chogwiritsa ntchito potengera miyezo yamakampani:

Kugwiritsa Ntchito Logic:Kugwiritsira ntchito tsamba lomwe ndi laling'ono kwambiri kuti likhale logwiritsira ntchito kusokoneza makina ndi tsamba, pamene tsamba lokulirapo silingatheke ndipo lingayambitse kugwedezeka. Mtundu wa makinawo umafanana ndi mphamvu, kulimba, ndi mphamvu zomwe zimafunikira kuyendetsa bwino kukula kwa tsamba.

(2) Kukometsa Magawo Odula

Kusankha zoyeneraliwiro lozungulira (RPM)ndimlingo wa chakudyandikofunikira kukulitsa moyo wa zida ndikukwaniritsa kudula kwabwino. Magawo awa amadalira kwathunthu zinthu zomwe zimadulidwa. Zida zolimba, zonyezimira zimafunikira kuthamanga pang'onopang'ono komanso kutsika kwa chakudya.

Gome lotsatirali, lochokera ku data yamakampani ya masamba a 285mm ndi 360mm, limapereka chidziwitso chaLiniya LiwirondiDyetsani Pa Dzino.

Mfundo Zazikulu:

• Liniya Liwiro (Liwiro la Pamwamba):Izi ndizokhazikika zomwe zimagwirizana ndi RPM ndi diameter ya tsamba. Kuti tsamba lokulirapo likhalebe ndi liwiro lofananira, RPM yake iyenera kukhala yotsika. Ichi ndichifukwa chake tsamba la 360mm lili ndi malingaliro otsika a RPM.
• Chakudya pa Dzino:Izi zimayesa kuchuluka kwa zinthu zomwe dzino lililonse limachotsa. Pazinthu zolimba monga chitsulo chachitsulo (SKD11), chakudya chochepa kwambiri ndichofunikira kuti nsonga za carbide zisagwedezeke ndi kupanikizika kwambiri. Pazitsulo zofewa za carbon low (Q235), mlingo wapamwamba wa chakudya ungagwiritsidwe ntchito kupititsa patsogolo kudula bwino.
• Chitsulo chosapanga dzimbiri:Izi ndi "gummy" komanso chowongolera kutentha kosakwanira. Kuthamanga pang'onopang'ono kwa mzere ndikofunikira kuti mupewe kuuma kwa ntchito komanso kutentha kwambiri pamphepete, komwe kumatha kuwononga tsamba.

5. Kugwira ndi Kusamalira: Kulemba Chilemba, Kuyika, ndi Kusunga

Kutalika kwa nthawi komanso kugwira ntchito kwa tsamba la macheka kumadaliranso kagwiridwe kake ndi kasungidwe kake, komwe kamayenera kutsatira mfundo ngati GB/T 191.

• Kulemba:Tsamba lililonse liyenera kukhala lodziwika bwino ndi zofunikira zake: miyeso (m'mimba mwake x makulidwe x bore), kuchuluka kwa mano, wopanga, ndi RPM yotetezeka kwambiri. Izi zimatsimikizira chizindikiritso cholondola komanso kugwiritsa ntchito moyenera.
• Kuyika:Masamba ayenera kupakidwa bwino kuti ateteze mano osalimba a carbide kuti asakhudzidwe panthawi yoyendetsa. Izi nthawi zambiri zimaphatikizapo mabokosi olimba, zolekanitsa masamba, ndi zokutira zoteteza kapena zophimba mano.
• Posungira:Kusungirako moyenera ndikofunikira kuti zisawonongeke komanso dzimbiri.
  • Chilengedwe:Sungani masamba pamalo aukhondo, owuma, komanso osagwirizana ndi nyengo (kutentha kovomerezeka: 5-35°C, chinyezi chachifupi:<75%).
  • Kuyika:Masamba amayenera kusungidwa chopingasa (chophwatalala) kapena kupachikidwa pazingwe zoyenera. Osaunjika masamba pamwamba pa wina ndi mzake, chifukwa izi zingayambitse kumenyana ndi kuwonongeka kwa mano.
  • Chitetezo:Sungani masamba kutali ndi zinthu zowononga komanso kutentha komwe kumachokera.
