Abstract
Der im Patentanspruch angegebenen Erfindung liegt das Problem zugrunde, Spiralbohrer Typ N in der Größe von 1,00 - 10,00 mm in kurzer Zeit mit einer Doppelschleifmaschine / einem Schleifbock jeglicher Art, ohne besondere Vorkenntnisse der auszuführenden Person und aus Gründen der Nachhaltigkeit nachzuschleifen.Die mit der Vorrichtung zur Montage an eine Doppelschleifmaschine / Schleifbock zum manuellen Scharfschleifen von Spiralbohrern Typ N in der Größe von 1,00 - 10,00 mm erzielten Vorteile bestehen darin, dass man mit Hilfe jeder Doppelschleifmaschine / jedes Schleifbockes und dieser Vorrichtung Spiralbohrer Typ N in der Größe von 1,00 - 10,00 mm in weniger als fünf Minuten unter Einhaltung der Winkel zwischen den Hauptschneiden und dem Querschneidenwinkel nachschleifen kann. Des Weiteren muss die auszuführende Person nicht aus der Metallbranche kommen.The invention specified in the claim is based on the problem of regrinding type N twist drills in the size of 1.00 - 10.00 mm in a short time with a bench grinder / bench grinder of any kind, without special prior knowledge of the person to be performed and for reasons of sustainability. The advantages achieved with the device for mounting on a bench grinder / bench grinder for manual sharpening of type N twist drills in the size of 1.00 - 10.00 mm are that with the help of each bench grinder / bench grinder and this device, type N twist drills can regrind in a size of 1.00 - 10.00 mm in less than five minutes while observing the angle between the main cutting edges and the cross cutting edge angle. Furthermore, the person to be carried out does not have to come from the metal industry.
Description
Es ist bekannt:
- Das Nachschleifen von Spiralbohrern wird erforderlich, wenn Schneiden stumpf oder
- ausgebrochen sind.
- The regrinding of twist drills is necessary if the cutting edges are blunt or
- have broken out.
Dabei müssen:
- - Die Winkel zwischen den Hauptschneiden, die Spitzenwinkel eingehalten werden; ca. 118 Grad
- - Die Schneiden gerade sein
- - Die Schneiden die gleiche Länge haben
- - Die Schneiden mit der Bohrerachse gleiche Winkel bilden
- - Die Freiflächen richtig hinterschliffen werden
- - Die Querschneiden einen Winkel von ca. 55 Grad mit der Hauptschneide bilden.
- - The angles between the main cutting edges, the point angles are observed; approx. 118 degrees
- - The cutting edges will be straight
- - The cutting edges are the same length
- - The cutting edges form the same angle with the drill axis
- - The open areas are correctly relief-ground
- - The cross cutting edges form an angle of approx. 55 degrees with the main cutting edge.

Die Vorrichtung zum manuellen Scharfschleifen von Spiralbohrern Typ N in der Größe von 1,00 - 10,00 mm muss auf der Schleifmaschinenauflage / Schleifbockauflage montiert werden. Dabei muss die Abschlusskante der Vorrichtung
Der Spiralbohrer wird auf die Auflage
Die Auflage der Schleifmaschine / des Schleifbockes muss mittig zum Durchmesser der Schleifscheibe stehen und durch die Vorrichtung lt. Patentanspruch steht der Bohrer dann ca. 1,50 cm oberhalb der Schleifscheibenmitte.The support of the grinding machine / bench grinder must be in the middle of the diameter of the grinding wheel and, due to the device according to the patent claim, the drill is then approx. 1.50 cm above the center of the grinding wheel.
Der Spiralbohrer muss am Anschlag
Die erste Hauptschneide des Spiralbohrers muss nun horizontal ausgerichtet werden. Danach wird der Spiralbohrer nach vorne bis an die Schleifscheibe geschoben und im Anschluss der Spiralbohrerschaft ca. 10 - 30 Grad nach unten gedrückt zum Anschleifen des Freiwinkels.The first main cutting edge of the twist drill must now be aligned horizontally. Then the twist drill is pushed forward up to the grinding wheel and then the twist drill shaft is pushed down approx. 10 - 30 degrees to grind the clearance angle.
Nun wird der Spiralbohrer um 180 Grad gedreht. Am Anschlag der Vorrichtung anliegend, wird die zweite Hauptschneide nun horizontal ausgerichtet und der Spiralbohrer an die Schleifscheibe geschoben, parallel zur Auflage der Schleifmaschine / des Schleifbockes. Now the twist drill is rotated 180 degrees. Next to the stop of the device, the second main cutting edge is now aligned horizontally and the twist drill is pushed against the grinding wheel, parallel to the support of the grinding machine / bench grinder.
Danach muss der Spiralbohrerschaft wieder ca. 10 - 30 Grad nach unten gedrückt werden zum Anschleifen des Freiwinkels der zweiten Hauptschneide.Then the twist drill shaft has to be pressed down approx. 10 - 30 degrees again to grind the clearance angle of the second main cutting edge.
Der Winkel zwischen den beiden Bohrschneiden, ca. 118 Grad, entsteht dann automatisch durch den Anschlag der Vorrichtung.The angle between the two cutting edges, approx. 118 degrees, is then automatically created by the stop of the device.
Die beiden Hauptschneiden müssen gleich lang angeschliffen werden.The two main cutting edges must be ground to the same length.
Der Querschneidenwinkel von ca. 55 Grad ergibt sich automatisch nach der Ausführung der o. g. Arbeitsgänge.The cross-cutting angle of approx. 55 degrees results automatically after the execution of the above. Operations.
