Description

Die Erfindung betrifft einen Gewindebohrsr, der einen zentralen, axial verlaufenden Kanal zum Durchleiten von Schmier- und Kühlflüssigkeit aufweist.The invention relates to a threaded drill which has a central, axially extending channel for the passage of lubricating and cooling fluid.

Bsi bekannten Gewindebohrern dieser Art, die überwiegend maschinell verwendet werden, ist der Kanal zum Durchleiten der Schmier- und Kühlflüssigkeit als einfache Durchgangsbohrung ausgeführt. Die Schmier- und Kühlflüssigkeit kann aus dieser Bohrung lediglich an der unseren Stirnfläche desIn known taps of this type, which are mainly used in machines, the channel for the passage of the lubricant and coolant is designed as a simple through hole. The lubricant and coolant can only flow out of this hole at the front face of the Bohrers axial austreten, so daß in manchen Anwendungsfällen eine ausreichende Schmierung und Kühlung im schneidenden Gewindebereich fehlt. Dies führt dann zu unsauberen Gewinden, botifm Verschleiß des Gewindebohrers oder sogar zu dessen Bruch.drill, so that in some applications there is insufficient lubrication and cooling in the cutting thread area. This then leads to dirty threads, excessive wear of the tap or even to its breakage.

Der Erfindung liegt daher die Aufgabe zugrunde., einen Gewindebohrer der gattungsgemäßen Art so zu gestalten, daß einwandfreie Gewinde bei hoher Standzeit des Bohrers geschnitten werden können.The invention is therefore based on the object of designing a tap of the generic type in such a way that perfect threads can be cut with a long service life of the drill.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Kanal nach Art einer Sackbohrung ausgebildet ist und fiber zumindest eine radial angeordnete Bohrung in eine der Spannuten des Gewindebohrers mündet.This object is achieved according to the invention in that the channel is designed in the manner of a blind bore and opens into one of the chip grooves of the tap via at least one radially arranged bore.

Eine weitere. Verbesserung der Zufuhr von Schmier- und Kühlflüssigkeit ist gemäß einer bevorzugten AusfÜhrungsform der Erfindung dadurch gegeben, daß der Kanal über eine entsprechende Anzahl radialer Bohrungen zu jeder der spannuten hin offen ist.A further improvement in the supply of lubricant and cooling fluid is provided according to a preferred embodiment of the invention in that the channel is open to each of the chip grooves via a corresponding number of radial bores.

Die mit dem Gegenstand der Erfindung erzielbaren Vorteile* bestehen insbesondere darin, daß gerade in problematischen Anwendungsfällen eine gezielte Kühlung und Schmierung des Gewindebereiches erfolgt, wobei zugleich die dort anfallenden Späne beseitigt werden. Saubere Gewinde und hohe Standzeiten für den Gewindebohrer sind die günstigen Folgen.The advantages* that can be achieved with the subject matter of the invention consist in particular in the fact that, especially in problematic applications, targeted cooling and lubrication of the thread area takes place, while at the same time the chips that accumulate there are removed. Clean threads and a long service life for the tap are the beneficial consequences.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigenAn embodiment of the invention is shown in the drawing and is described in more detail below. They show

Fig. 1 einen Gewindebohrer, teils in Seitenansicht, teils im Längsschnitt,Fig. 1 a tap, partly in side view, partly in longitudinal section,

Fig. 2 einen Querschnitt durch den unteren Gewindeabschnitt des Gewindebohrers nach Fig. 1.Fig. 2 shows a cross section through the lower threaded section of the tap according to Fig. 1.

Der Gewindebohrer besteht im wesentlichen aus einem Schaft und einem Gewindeteil 5, die einen zentralen, axial verlaufenden Kanal 1 aufweisen. Dieser Kanal 1 dient dem Durchleiten von Schmier- und Kühlflüssigkeit. Wie ersichtlich, ist der Kanal 1 nach Art einer Sackbohrung ausgebildet und über jeweils eine radial angeordnete Bohrung 2 zu den Spannuten 3 des Gewindebohrers hin offen. Das Schmier- und Kühlmittel gelangt durch diese Bohrungen 2 unmittelbar zu den Schneiden des Gewindeteiles 5.The tap essentially consists of a shaft and a threaded part 5, which have a central, axially running channel 1. This channel 1 is used to conduct lubricant and coolant. As can be seen, the channel 1 is designed like a blind hole and is open to the chip grooves 3 of the tap via a radially arranged hole 2. The lubricant and coolant pass through these holes 2 directly to the cutting edges of the threaded part 5.
