Yadda ake zaɓar injin servo da injin stepper?

Yanayin tuƙi na injin yanke laser galibi yana tafiya ne ta hanyar injin. Wasu abokan ciniki suna fuskantar zaɓuɓɓuka yayin keɓance injin yanke laser na fiber. Shin don zaɓar injin servo ne ko injin stepper? Masana'antun injin yanke laser za su iya bincika bambance-bambancen da ke tsakanin hanyoyin tuƙi guda biyu daban-daban a gare ku, Da farko, ya kamata mu fahimci bambanci tsakanin injin servo da injin stepper da injin yanke laser ya zaɓa:

Ana iya amfani da injin servo da stepper don tuƙa injin yanke laser, kamfanoni da yawa suna siyan injin yanke laser don zaɓar na farko, me yasa? Injin servo yana da ƙarancin hayaniya da daidaito mai yawa. Ana amfani da injin servo na AC azaman na'urar tuƙi, wanda zai iya samar da madaidaicin madauki mai ƙarfi da aiki mai kyau ko tsarin sarrafa madauki mai rufewa kamar injin DC servo. Saboda tsarin babu goge na injin servo na AC, kusan babu kulawa, ƙaramin girma, wanda ke taimakawa wajen inganta gudu da ƙarfi. A halin yanzu, an maye gurbin injin DC servo a cikin babban tsarin servo na dijital ta amfani da babban microprocessor da na'urar sarrafa siginar dijital ta musamman (DSP), ainihin ikon sarrafa servo na hardware zuwa ikon sarrafa software. An cimma wasu algorithms na ci gaba a cikin ka'idar sarrafawa ta zamani, sannan kuma sun inganta aikin tsarin servo sosai, don haka sashin servo zai iya inganta inganci da daidaito na injin, amma farashin sashin servo drive shima yana da yawa. Tare da ci gaba a hankali na fasahar sarrafa servo, sashin servo drive yana zama babban ƙarfin sashin tuƙi a hankali, kuma farashin sashin servo drive yana raguwa a hankali.

Akwai nau'ikan direbobin servo guda biyu. Ɗaya yana amfani da sarrafa bugun jini. Wannan nau'in direba yana rufe madauki da injin, amma baya mayar da martani ga tsarin CNC. Ɗayan kuma yana amfani da yanayin sarrafa ƙarfin lantarki, ta hanyar ƙarfin wutar lantarki na sarrafa saurin motar, siginar amsawar motar ta hanyar martanin direba zuwa tsarin CNC don sarrafa matsayi.

Lokacin zabar na'urar tuƙi, ya zama dole a yi la'akari da rabon farashin na'urar tuƙi a cikin kayan aikin injin NC gaba ɗaya. Ƙananan farashin na'urar injin CNC gabaɗaya yana zaɓar na'urar tuƙi ta stepper, kuma mafi girman farashin na'urar injin yana zaɓar na'urar tuƙi ta servo. Koyaya, lokacin zaɓar na'urar tuƙi, ya kamata a yi la'akari da matsalar daidaitawa tsakanin na'urar tuƙi da tsarin CNC. Lokacin zaɓar tsarin kula da madauki mai rufewa, dole ne a zaɓi na'urar tuƙi ta servo mai rufewa. Tsarin servo na AC ya fi na'urar tuƙi a fannoni da yawa na aiki.
