MAKHALIDWE ABWINO OPANDA MASOKA OTHANDIZA

Kulimba kwa fracture poyerekezera ndi kukula kwambewu ndi zomwe zili ndi cobalt.

Pamene zinthu zimakhudzidwa ndi kupsinjika kwakunja, izi zimabweretsa zovuta zamakina.Pazimenezi, mphamvu zonse ndi ductility za zinthu zimasonyeza maziko a lingaliro la kulimba.Mwa kuyankhula kwina, kulimba kumatanthauzidwa ngati mphamvu yokana kusweka kapena kuphulika."Palmqvist Method" nthawi zambiri amagwiritsidwa ntchito kuti adziwe kuchuluka kwamphamvu, KIC.

Chonde nenani motere poyitanitsa:

*Zinthu Zawaya,Chitsulo Chotsika Kaboni.Chitsulo Chapakati cha Carbon.Chitsulo Chapamwamba cha Carbon.Stainless Steel.Brass.Aluminium.Iron.Optimum with Code of Materials.

*Masitayelo amutu, chonde tchulani mutu ukakhala ndi washer.

* Hollow screw, chonde tchulani ikagwiritsidwa ntchito ngati screw.

* wononga katatu, chonde tchulani mainchesi a waya mukamagwiritsa ntchito wononga makona atatu.

* Non-standard screw, chonde phatikizani zojambula kapena zitsanzo zikagwiritsidwa ntchito pa screw screw.

Mafunso omwe amapezeka pakugwiritsa ntchito screw ndi nut mold:

1. Mphunzitsi waluso ali ndi chidziwitso cha nkhungu ndi mapangidwe apangidwe , kusanthula chifukwa cha kugawa kosamveka kwa chiŵerengero cha kufa kupsinjika ndi kusinthika.

2.Ukhondo wa nkhungu, kumaliza dzenje lamkati sikukwanira.

3.Kulimba kwa zida za manja a chipolopolo, kukana kutentha, komanso kuuma kwa chithandizo cha kutentha ndizosamveka.

4.Kuti apulumutse mtengo wopangira, adasankha chitsulo chosauka cha tungsten carbide ndi waya wa waya, mafotokozedwe a aloyi ndi kuba zinthu zokhomerera mawilo akulu ndizosamveka.

5.The collider si yoyenera, popanda kusintha mafuta ndi kufufuza makina kwa nthawi yaitali.

6.Mphunzitsi waluso wokonza ayenera kukhala ndi luso lapamwamba.
