For a diameter-length-ratio from 15xD one generally refers to gun drilling. Gun drills are for example applied for the machining of camshafts, crankshafts, drive shafts, injectors, drill pipes for oil production, in the medical and the food industry. Dependent on the requirements of the hole, the machine conditions, the batch size and the drilling depth Guhring determines the most economically efficient tool option.

Thanks for the informative video. I'd like to know more about drilling depth limitations for conventional gun drilling on a MC, as it's mentioned that generally a 40D length is the limit per drill diameter, but two additional 40D steps can be taken if using a slightly smaller drill. So the following questions: 1) What is the technical reason for the limit? If the drilling depth shaft can "whip", why is the slightly smaller following drill stable? 2) What are the usual methods for following a three-step depth hole to make it uniform in diameter for the full lenght? 3) What is the expected straightness and uniformity of diameter for a stationary work/rotating gun drilled hole at maximum depth? Thanks for your time!

Hi David, Thank you very much for your interest and for this enquiry. We have given answers to your questions: 1) What is the technical reason for the limit? If the drilling depth shaft can "whip", why is the slightly smaller following drill stable? 👉The steel tube is physically limited in stability for a free tube length of 45/47xD means 40xD drill depth. The solid carbide deep hole drills are able to drill up to 80xD. 2) What are the usual methods for following a three-step depth hole to make it uniform in diameter for the full lenght? 👉Our standard is to use 0,05mm steps smaller diameters for the following drills. If the hole tolerance allows it you can do this procedure up to maximum available tool length in 40xD steps. For specials several times we use a 0,03mm step. 3) What is the expected straightness and uniformity of diameter for a stationary work/rotating gun drilled hole at maximum depth? 👉The major rule for runout of the deep hole drills is 0,1/100mm. While using the above mentioned procedure the runout values could be up to 0,1-0,15 depending of work piece form and position of the hole and kind of material. If you require any further information, please feel free to contact us.

No mention of high pressure cutting oil feed down the center for chip removal back down the outer "v" slot being critical to the maintenance of centering. Too high a pressure and the oil coming out the rear of cutter head grind relief-land forces the drill off center while too little pressure allows the drill to harmonically vibrate and drill off-size.

But how is the hole in the gun drill is drilled? Or do you just extrude a tube and machine it to shape?

eine reibahle in einer handbohrmaschine einspannen und rotieren lassen und mit einen Winkelschleifer die Reibahle rund abschleifen auf 5.56mm oder . Dann rotglühend durcherhitzen (brenner) und per Zange und schraubstock torsieren/verdrehen . Dann ein gut Torsiertes Stück rausflexen , so 4-5cm + ein wenig hals von der Reibahlenaufnahme (durchmesser) dran lassen , weil man es mit einen Durchschlag und Hammer später schlägt, um es durch den Lauf zu treiben . . Das teil per Hammer und Durchschlag durch den 5,56 mm Lauf treiben . Die Reibahle ist Härter als Dein Lauf und durch die Torrsion räumt die Reibahle die Züge und Felder in den Lauf und zwar gedreht - eine 7mm oder 8mm Reibahle sollte gut sein oder eine 9mm - die aufnahme der Reibahle Durchmesser sollte unter 5.56mm , damit es später durch den Lauf paßt. beachten muß man , das das Projektil 5.56mm Durchmesser hat . Vielleicht sollte die Reibahle daher auf 5.56mm geschliffen werden , das geht mit Bohrmaschine und Flex gut , wenn man Null Grad Winkel verwendet und die Reibahle gleichmäßig rund abschleift . Der Kernbohrdurchmesser im Lauf vielleicht 5,5mm . dann haste Felder mit 0,03mm Tiefe - aber Du willst ja sicherlich knapp 1/10mm tiefe Felder , also mußte entsprechend die Bohrung 5.3mm oder 5,4 und die Reibahle 5.56 . Ohne Züge hatte Ich 5.56mm Bohrung ,ungeschliffen und die Kugel jagte gut durch den Lauf .
