Description
Die Erfindung betrifft ein Verfahren zum streifenfreien Schleifen ebenflächiger Werkstücke mittels eines schmalen, durch eine Kontaktrolle od. dgl. gegen das Werkstück angedrückten endlos umlaufenden Schleifbandes, bei dem die Werkstückvorschubrichtung quer zur Umlaufrichtung des Schleifbandes gerichtet ist und der Vorschub des Werkstückes schrittweise erfolgt.The invention relates to a method for streak-free grinding of flat workpieces by means of a narrow endless grinding belt pressed against the workpiece by a contact roller or the like, in which the workpiece feed direction is directed transversely to the direction of rotation of the grinding belt and the workpiece is fed step-by-step.
Dieses Verfahren entspricht dem allgemein bekannten Stand der Technik beim Schleifen ebenflächiger Werkstücke mittels eines endlos umlaufenden, schmalen und durch eine Kontaktrolle od. dgl. gegen das Werkstück angedrückten Schleifbandes bzw. mittels sogenannter Langbandschleifmasrhinen. Wird das Werkstück entsprechend der Schleifbandbreite schrittweise durch die Maschine vorgeschoben, kann dabei jedoch ein unerwünschtes, streifenförmiges Schleifmuster auf der Werkstückoberfläche entstehen.This method corresponds to the generally known state of the art for grinding flat surfaces Workpieces by means of an endlessly rotating, narrow and od by a contact roller. The like. Against the Workpiece pressed on sanding belt or by means of so-called long-belt sanding machines. It will The workpiece can be advanced gradually through the machine according to the width of the sanding belt however, an undesirable, stripe-shaped grinding pattern is created on the workpiece surface.
Aufgabe der vorliegenden Erfindung ist es daher, das Auftreten dieses Streifenmusters auf der Werkstückoberfläche zu vermeiden.The object of the present invention is therefore to prevent this stripe pattern from occurring on the workpiece surface to avoid.
Dies wird dadurch erreicht, daß die Vorschubschritte abwechselnd unterschiedlich groß und entgegengesetzt gerichtet sind.This is achieved in that the feed steps are alternately different in size and directed in opposite directions.
Die Ausbildung eines Streifenmusters wird sonach also dadurch vermieden, daß sich infolge des pilgerschrittartigen Vorschubs des Werkstückes die Schleifspuren in bestimmter Weise überlappen und dadurch besser ineinander verlaufen bzw. sich gegenseitig verwischen und aufheben.The formation of a stripe pattern is therefore avoided in that as a result of the pilgrim step-like Advance of the workpiece overlap the grinding marks in a certain way and thereby merge better or blur and cancel each other out.
Anhand einer Zeichnung wird nachfolgend noch eine Langbandschieifmaschine beschrieben, mittels der sich das erfindungsgemäße Verfahren durchführen läßt. In der Zeichnung zeigtWith the aid of a drawing, a long belt sanding machine is described below, by means of which the method according to the invention can be carried out. In the drawing shows
F i g. 1 den Grundriß einer im Hinblick auf das erfindungsgemäße Verfahren ausgestalteten Langbandschieifmaschine undF i g. 1 shows the plan of a long belt sanding machine designed with a view to the method according to the invention and
Fig.2 den Weg der Kontaktrolle gegenüber dem Werkstück.Fig.2 shows the path of the contact roller compared to the Workpiece.
Auf einem zwischen zwei Ständern angeordneten Tisch 1 liegt das Werkstück 2. Der Tisch 1 mit dem Werkstück 2 wird schrittweise mit unterschiedlich großen und entgegengesetzt gerichteten Vorschubschritten unter dem endlos umlaufenden Schleifband 3 hindurchgeschoben, wobei das Schleifband 3 mittels einer Kontaktrolle 4 gegen das Werkstück 2 angedrückt wird. Die Kontaktrolle 4 ist an einem Schlitten 5 angeordnet, der sich auf einer Führung 6 horizontal quer zur Vorschubrichtung des Tisches 1 verfahren läßt und in seinen Endstellungen jeweils mittels eines Schalters 7 umgesteuert wird.The workpiece 2 lies on a table 1 arranged between two stands. The table 1 with the Workpiece 2 is moved step by step with differently sized and oppositely directed feed steps pushed under the endlessly rotating sanding belt 3, the sanding belt 3 by means of a contact roller 4 is pressed against the workpiece 2. The contact roller 4 is on a slide 5 arranged, which can be moved horizontally on a guide 6 transversely to the feed direction of the table 1 and is reversed in each of its end positions by means of a switch 7.
Die Fig.2 zeigt den Ablauf des Schleifvorganges angefangen vom Punkt A bis Punkt B. Das Schleifband 3 erzeugt aufgrund verschiedener Ursachen im Bereich seiner Außenkanten auf dem Werkstück Streifen. Um die bei einer Schleifbahn entstehenden Streifen zu entfernen, werden daher die jeweiligen Schleifbahnen durch unterschiedlich große und entgegengesetzte Vorschubschritte überlappt, wodurch beim Durchlauf des Werkstückes 2 eine streifenfreie Oberfläche erzielt wird.2 shows the sequence of the grinding process starting from point A to point B. Due to various causes, the grinding belt 3 produces strips in the area of its outer edges on the workpiece. In order to remove the stripes that arise in a grinding path, the respective grinding paths are therefore overlapped by differently sized and opposing feed steps, as a result of which a streak-free surface is achieved when the workpiece 2 passes through.
