The PCB ibhodi ngokuvamile inamathiselwe ndawonye izingqimba eziningana zezinto ze-resin, futhi ucwecwe lwethusi lwangaphakathi lusetshenziselwa ukuhlanganisa izintambo, futhi kukhona izingqimba ezi-4, 6, nezi-8. Phakathi kwazo, ukumba kuthatha u-30-40% wezindleko zamabhodi wesifunda aphrintiwe, futhi ukukhiqizwa ngobuningi kuvame ukudinga imishini ekhethekile kanye nezinsimbi zokubhoboza. Izingcezu ezinhle zokubhola ze-PCB zisebenzisa izinto ezisezingeni eliphezulu ze-carbide zikasimende, ezinokuqina okuphezulu, ukunemba kwesikhundla sembobo ephezulu, ikhwalithi enhle yodonga lwembobo, nempilo ende.

Kunezici eziningi ezithinta ukunemba kwesikhundla sembobo kanye nekhwalithi yodonga lwembobo yokumba. Lesi sihloko sizoxoxa ngezinto eziyinhloko ezithinta ukunemba kwesikhundla sembobo kanye nekhwalithi yodonga lwembobo yokumba, futhi siphakamise izixazululo ezihambisanayo zereferensi yakho.

3. Izizathu ezingenzeka: isivinini esinganele sokuphotha (RPM)

Izinyathelo zokulwa: lungisa izinga lokuphakelayo nesivinini sokuzungezisa sibe sesimweni esihle kakhulu, futhi uhlole ukuhluka kwesivinini sokuzungezisa.

4. Isizathu esingaba khona: izinga lokudla lishesha kakhulu

I-Countermeasure: Yehlisa izinga lokuphakelayo (IPM).

Kungani kunezindonga zembobo eRough?

1. Isizathu esingaba khona: inani lokuphakelayo lishintshe kakhulu.

I-Countermeasure: Gcina inani lokuphakelayo elingashintshi.

2. Isizathu esingaba khona: izinga lokudla lishesha kakhulu

Izinyathelo eziphikisanayo: Lungisa ubudlelwano phakathi kwezinga lokuphakelayo kanye nesivinini sokubhoboza kuya esimweni esihle kakhulu.

3. Isizathu esingaba khona: ukukhetha okungafanele kwesembozo

I-Countermeasure: Faka esikhundleni sekhava.

4. Isizathu esingaba khona: i-vacuum enganele esetshenziselwa i-drill engashintshi

Izinyathelo zokulwa: Hlola uhlelo lwe-vacuum lomshini wokumba, futhi uhlole ukuthi ijubane lokuphotha liyashintsha yini.

5. Izizathu ezingenzeka: izinga lokuhoxisa elingavamile

Izinyathelo eziphikisanayo: lungisa ubudlelwano phakathi kwezinga lokuhlehlisa kanye nesivinini sokubhoboza sibe sesimweni esihle kakhulu.

6. Izizathu ezingenzeka: unqenqema olungaphambili lwethiphu yenaliti lubonakala luphukile noma luphukile

Izinyathelo Zokulwa: Hlola isimo sebhithi yokubhoboza ngaphambi kokungena emshinini, futhi uthuthukise umkhuba wokubamba kanye nokuthatha i-drill bit.

Kungani ukuzungeza komumo wembobo kunganele?

1. Isizathu esingaba khona: i-spindle igobile kancane

I-Countermeasure: Faka esikhundleni i-bearing ku-shaft eyinhloko (Ukuthwala).

2. Izizathu ezingenzeka: ukugqama kwephuzu lokubhoboza noma ububanzi obuhlukile bonqenqema lokusika

Izinyathelo zokulwa: Hlola i-drill bit ngokukhulisa izikhathi ezingama-40 ngaphambi kokungena emshinini.

Kungani kukhona udoti oboshiwe onezimpande zelotus eziphukile ezitholakala endaweni yebhodi?

1. Isizathu esingaba khona: ikhava ayisetshenziswa

I-Countermeasure: engeza ipuleti lekhava.

2. Isizathu esingaba khona: imingcele yokumba engafanele

Izinyathelo zokulwa: yehlisa izinga lokuphakelayo (IPM) noma ukhuphule isivinini sokubhoboza (RPM).

Kungani iphini lokubhoboza kulula ukuliphuka?

1. Okungaba imbangela: ukuphela kwe-spindle ngokweqile

I-Countermeasure: Zama ukuchezukisa i-shaft eyinhloko.

2. Isizathu esingenzeka: ukusebenza okungalungile komshini wokumba

Izinyathelo Zokuphikisa:

1) Hlola ukuthi unyawo lokucindezela luvimbelwe yini (UKUGQUMA)

I-2) Lungisa ukucindezela konyawo lokucindezela ngokuvumelana nesimo sethiphu yokubhoboza.

3) Hlola ukuhluka kwejubane lokuphotha.

I-4) Isikhathi sokusebenza sokumba ukuze uhlole ukuzinza kwe-spindle.

3. Isizathu esingaba khona: ukukhetha okungalungile kwezingcezu zokubhoboza

Izinyathelo zokulwa: Hlola ijiyomethri ye-drill bit, hlola ukukhubazeka kwebhithi yokubhoboza, futhi usebenzise i-drill bit enobude obufanele be-chip recess.

4. Izizathu ezingenzeka: isivinini sokubhola esinganele kanye nezinga lokuphakela eliphezulu kakhulu

I-Countermeasure: Yehlisa izinga lokuphakelayo (IPM).

5. Izizathu ezingenzeka: inani lezingqimba ze-laminate landa

I-Countermeasure: Yehlisa inani lezendlalelo zebhodi elaminate (Stack Height).
