Paipa Drill Taumaha
Ko te putorino putunga taumaha taumaha te waahi whakawhiti i waenga i te kara drill me te putorino drill.Kaore e taea e ia te whakaiti noa i te ahotea-hanga i roto i te hononga o te kara drill me te putorino drill, engari whakaiti hoki i te kakahu i runga i OD.
Ko te putorino putunga taumaha taumaha he mea hanga mai i tetahi waahanga o te pae totoka AISI 4145H, he mea whakamahana katoa, he rite nga ahuatanga tinana katoa ki te putanga hou o API spec7.
He paerewa te here a te HWDP i runga i nga hononga taputapu me te raruraru o te pokapū.Ko nga momo taapiri uaua ko Arnco 100XT me 100XT.Ko nga miro katoa he mea phosphated, he parahi, he mahi makariri ranei.Ko nga hononga katoa kua rite ki nga parepare miro maitai aki.Ko nga panui katoa he miihini me nga miihini CNC - he miro takirua me nga miro motuhake.
