Feinbohrer-Schleifvorrichtung mit einem Translations - und 3 Rotations-Fine drill grinding device with one translation and 3 rotation

Freiheitsgraden.degrees of freedom.

Die marktgängigen Bohrerschleifgerate enden bei 3.5 mm Durchmesser. Eine Vielzahl von Anwendungen verlangt jedoch 0.8 mm für die Platinenfertigung oder auch 1.6 mm für M2 Gewinde.The drill grinders available on the market end at 3.5 mm diameter. However, a large number of applications require 0.8 mm for circuit board production or 1.6 mm for M2 threads.

Es liegt also nahe, marktgängige Schleifgeräte mit einer Zusatzvorrichtung zu versehen, welche Bohrer unter 1 mm zu schleifen gestattet.It therefore makes sense to equip commercially available grinding machines with an additional device that allows drill bits under 1 mm to be ground.

Wegen der notwendigen Festigkeit ist die Bohrerseele bei den kleinen Durchmessern sehr dick gegenüber den verbleibenden Schneidphasen, weswegen die Symmetrie nur optisch bestimmt werden kann. Der Grundeinstellung auf der Vorrichtung verlangt demnach eine Lupe.Because of the necessary strength, the drill core is very thick in the small diameters compared to the remaining cutting phases, which is why the symmetry can only be determined visually. The basic setting on the device therefore requires a magnifying glass.

Der SchleifVorgang selbst erfolgt in 3 Achsen, nämlich 3 Rotationsbewegungen und einer Translationsbewegung, der Zustellung.The grinding process itself takes place in 3 axes, namely 3 rotational movements and one translational movement, the infeed.

Die Drehung um die Hochachse erzeugt den Freiwinkel der Bohrerschneide, der Spanwinkel ist immer gegeben.The rotation around the vertical axis creates the clearance angle of the drill cutting edge, the rake angle is always given.

Die Drehung um die Querachse erzeugt den Spitzenwinkel - gewöhnlich 90° - die Drehung um die Längsachse,mit den Endlagen 0° und 180°, die Symmetrie der Schneiden.The rotation around the transverse axis creates the tip angle - usually 90° - the rotation around the longitudinal axis, with the end positions 0° and 180°, the symmetry of the cutting edges.

Die Achsialverschiebung der Längsachse- Zustellung - bestimmt die Schleiftiefe, meist wenige zehntel Millimeter. Sie ist daher mittels Mikrometerschraube einzustellen.The axial displacement of the longitudinal axis - feed - determines the grinding depth, usually a few tenths of a millimeter. It must therefore be adjusted using a micrometer screw.

Erfindungsgemäss wird die Aufgabenstellung durch eine Vorrichtung gelöst, welche aus einem Adapter (3) , verbunden mit dem Systemträger (2) besteht. Der Systemträger (2) trägt die Gradierung, welche den Freiwinkel bestimmt. Der Systemträger (2) ist gleitend mit dem Längsverstellschlitten (4) verbunden, welcher die Mikrometerschraube (1), die Spitzenwinkeljustage (5) und das Spannzangenscharnier (6) trägt.
Das Spannzangenscharnier trägt die Spannzange (10), die SpannzangenwelleAccording to the invention, the problem is solved by a device which consists of an adapter (3) connected to the system carrier (2). The system carrier (2) carries the graduation which determines the clearance angle. The system carrier (2) is slidably connected to the longitudinal adjustment slide (4) which carries the micrometer screw (1), the tip angle adjustment (5) and the collet hinge (6).
The collet hinge carries the collet (10), the collet shaft

(8), das Spannzangenwellenlager (7) mit den Anschlägen 0° und 180 °.(8), the collet shaft bearing (7) with the stops 0° and 180 °.

Der Spielfreihaltung dient die Schraubenfeder (9).The coil spring (9) serves to keep the clearance free.

Der Drehgriff (11) bewirkt die Drehung um die Längsachse.The rotary handle (11) causes rotation around the longitudinal axis.

Der Fixierung der Schneidensymmetrie dient die Stecklupe (12), welche vor der Bearbeitung auf das abgeklappte Spannzangenscharnier (6) aufgesteckt wird. Dann wird der Bohrer so eingerichtet, dass die gemeinsame Schneidenverbindungslinie mit der Vertikalen fluchtet.The plug-in magnifying glass (12) is used to fix the cutting edge symmetry and is attached to the folded-down collet hinge (6) before machining. The drill is then set up so that the common cutting edge connecting line is aligned with the vertical.
