Abstract

Det er fremlagt en fremgangsmåte og anordning for en enkeltturs vindus- fresingssystem. Systemet er spesielt nyttig ved bruk av gjennomrørsformål der fresene (20) blir drevet på kveilet rør (10) i kombinasjon med en borekronemotor (12). Fortrinnsvis, er ledekilen (50) kjørt gjennom røret og satt i posisjon. Frese- sammenstillingen blir typisk kjørt inn etter at ledekilen (50) er orientert og satt på plass. Fresesammenstillingen er støttet av en borekronemotor (12) som i sin tur blir kjørt inn med kveilet rør (10). Pilotfresen eller ledefresen er av en spesiell form, slik at den minimaliserer dens dreiemoments behov for å starte fresingen av vindu. En sliteinnretning som tjener som føring (46) er plassert bak utgangsfresen (26) og tjener med en fleksibel sammenføyningsdel (14) over den etterfølgende fresen i orientering av den første fresen inn i foringsrøret og vekk fra ledekilen (50). Den etterfølgende fresen eller fresene omfatter en gradvis økning i tverrsnittsarealet langs den eller deres lengde, som også minimaliserer det nødvendige dreiemoment for borekronemotoren (12). Systemet er i stand til å penetrere tykke foringsrør, slik som et standardvekt 17,8 cm foringsrør i omtrent 3 timer eller mindre.
