Ho sututsa spindle ho feta moroalo o khothaletsoang kapa meeli ea RPM ke sesosa se tloaelehileng sa ho chesa haholo. Ho jara kapa ho potlaka ho feta tekano ho baka mocheso o feteletseng, ho hatella likarolo, 'me ho potlakisa ho roala.

l  Meeli ea Moroalo : Ho feta torque ea spindle kapa matla a ho fokotsa mojaro ho ka baka khatello ea motlakase, e lebisang ho ho feteletseng le ho senyeha ho ka bang teng ha shaft kapa ho senya libere.

l  Meeli ea Lebelo : Ho tsamaisa spindle ka holim'a RPM ea eona e lekantsoeng ho eketsa khohlano ka li-bearings le ho hlahisa mocheso o feteletseng, ho beha kotsing ea ho hlōleha ha motlakase kapa ho senyeha ha lubricant.

l  Lisebelisoa tsa Tlhokomelo : Sebelisa software ea hau ea CNC ho lekola mojaro oa spindle oa nako ea 'nete, lebelo le mocheso. Litsamaiso tse ngata li u lumella ho beha li-alarms bakeng sa ho feta menyako e sireletsehileng, ho thusa ho thibela ho chesa haholo.

Mekhoa e Metle:

l  Khomarela RPM e boletsoeng ke moetsi le meeli ea mojaro ho fokotsa tlhahiso ea mocheso.

l  Kamehla hlahloba lisebelisoa tsa ho pholisa (mohlala, moea kapa metsi) ho netefatsa hore li sebetsa ho latela litlhahiso tsa bukana.

l  Lekola likutu tsa mocheso ka li-sensors tsa boemo kapa setšoantšo sa mocheso ho fumana ho kheloha pele.

Ho latela melaoana ena ho fokotsa khatello ea maikutlo e amanang le mocheso, ho thibela mocheso o feteletseng, 'me ho lelefatsa bophelo ba spindle ea hau, ho boloka mochini oa hau oa CNC o sebetsa hantle le ka bokhabane.

Qetello

Ho chesa ho feta tekano ho CNC spindle ea hau ke lets'oao le hlakileng la temoso le hlokang tlhokomelo. Ebang e bakoa ke li-bearings tse tsofetseng, ho se tsamaisane hantle, mathata a motlakase, kapa maemo a tikoloho, mocheso o feteletseng o bontša mathata a ka mpefalang haeba a hlokomolohuoa. Ha ho sa laoloe, mocheso o feteletseng o ka lebisa ho se sebetseng ha likaroloana, ho lokisoa ho bitsang chelete e ngata, le ho fokotsa nako haholo.

Ka ho tseba lisebelisoa tsa ho hlahloba tse kang ho nka litšoantšo ka mocheso, lisebelisoa tsa ho thothomela, le li-stethoscope, le ho khomarela litataiso tsa moetsi bakeng sa tlhokomelo, mojaro, le lebelo, u ka tšoara mathata pele ho nako 'me ua boloka spindle ea hau e sebetsa hantle. Litaolo tsa tikoloho le ho beha mochine ka nepo ho fokotsa kotsi ea mathata a amanang le mocheso.

Spindle ea hau ke pelo ea mochini oa hau oa CNC. E sireletse ka tlhokomelo e matla, 'me e tla u putsa ka ts'ebetso e tšepahalang, e tšoarellang nako e telele.

Lipotso ka CNC Spindle

Mocheso o nepahetseng oa ho sebetsa bakeng sa spindle ea CNC ke ofe?
Li-spindle tse ngata li sebetsa hantle pakeng tsa 40°C le 60°C (104°F–140°F), empa sheba lintlha tsa moetsi.

Ke lokela ho tlotsa spindle eaka hangata hakae?
Khafetsa ea ho tlotsa e ipapisitse le litataiso tsa ts'ebeliso le moetsi, hangata lihora tse ling le tse ling tse 500-1,000 tsa ts'ebetso.

Na mocheso o feteletseng o ka baka tšenyo e sa feleng?
E, ho chesa ka nako e telele ho ka senya li-bearing, lienjene, kapa likarolo tse ling, e leng ho lebisang ho lokisoeng ha chelete e ngata kapa ho nkeloa sebaka.

Na ho pholisa metsi ho molemo ho feta ho pholile moea?
Pholiso ea metsi e sebetsa haholo bakeng sa lits'ebetso tsa lebelo le holimo kapa tse boima, empa ho pholisa moea ho bonolo ebile ho lekane bakeng sa mesebetsi e bobebe.

Kakaretso ea nako ea bophelo ea spindle ea CNC ke efe?
Ka tlhokomelo e nepahetseng, li-spindle li ka nka lihora tse 10,000-20,000 tsa ho sebetsa, ho itšetlehile ka tšebeliso le maemo.
