Abstract
Description
Die Erfindung betrifft eine Werkzeugmaschine und ein Verfahren zur Umfangsprofilierung eines Werkstückes.The invention relates to a machine tool and a method for the circumferential profiling of a workpiece.
Schleifmaschinen weisen für die schleifende Bearbeitung von Werkstücken ein durch eine Schleifspindel rotierend angetriebenes Schleifwerkzeug, die Schleifscheibe, auf. Erfolgt eine schleifende Bearbeitung, so muss während dessen ein Kühlmittel zugeführt werden, das neben der kühlenden und damit Wärme abführenden Wirkung als Schmiermittel dient.Grinding machines have a grinding tool driven by a grinding spindle, the grinding wheel, for the grinding of workpieces. If a grinding processing, so must be supplied during which a coolant, which serves as a lubricant in addition to the cooling and thus heat dissipating effect.

Nachteilig bei all diesen Offenbarungen ist die unflexible Bearbeitungsweise des Werkstücks durch die Schleifscheibe bei gleichzeitigem präzisen Bearbeiten. Die Möglichkeiten der Formgebung können nicht ausgeschöpft werden, aufgrund des Mangels an räumlichem Bedarf und der Bewegungsfreiheit der Werkzeugspindel. Wobei die Werkzeugspindel und auch die Lagerung des Werkzeuges entweder sehr steif gelagert ist, um eine präzise Bearbeitung zu ermöglichen, oder die Lagerung des Werkstücks und/oder des Werkzeuges sind weniger exakt, um damit eine flexible Bearbeitung zu realisieren.A disadvantage of all these disclosures is the inflexible processing of the workpiece by the grinding wheel with simultaneous precise machining. The possibilities of shaping can not be exhausted, due to the lack of space requirements and the freedom of movement of the tool spindle. Wherein the tool spindle and the bearing of the tool is either very stiff stored to allow precise machining, or the storage of the workpiece and / or the tool are less accurate, so as to realize a flexible machining.
Der Erfindung liegt die Aufgabe zugrunde, eine Werkzeugmaschine zur Verfügung zu stellen, die bei geringem Raumbedarf, präzis arbeitet und eine hohe Flexibilität bezüglich des Bearbeitungsraumes ermöglicht.The invention has for its object to provide a machine tool that works precisely with low space requirements, and allows high flexibility with respect to the processing space.
Erfindungsgemäß wird diese Aufgabe durch eine Werkzeugmaschine entsprechend dem Patentanspruch 1 und einem Verfahren zur Umfangsprofilierung von Werkstücken gemäß Anspruch 7 gelöst.According to the invention this object is achieved by a machine tool according to the patent claim 1 and a method for the circumferential profiling of workpieces according to
Die Unteransprüche 2 bis 6 und 8 erläutern vorteilhafte Ausführungsformen der Erfindung.The
Die Erfindung besteht in der Angabe einer Werkzeugmaschine, insbesondere einer Präzisionswerkzeugmaschine, die mindestens aus einer Werkzeugspindel, einer Werkzeugaufnahme und einer Spannvorrichtung besteht. Dabei ist die Werkzeugspindel derart angeordnet, dass ein vertikales und horizontales Bearbeiten des Werkstückes in einem Bearbeitungsbereich von bis zu 110° von einer vertikalen Achse ausgehend in verschiedene Richtungen verschwenkbar ist. Eine Verbindung zwischen Werkzeugspindel und Werkzeugaufnahme ermöglicht einen Wechsel der Drehrichtung des Werkzeuges. In einer bevorzugten Ausgestaltung ist die Werkzeugmaschine eine Präzisionsschleifmaschine.The invention consists in specifying a machine tool, in particular a precision machine tool, which consists of at least one tool spindle, a tool holder and a clamping device. In this case, the tool spindle is arranged such that a vertical and horizontal machining of the workpiece in a processing range of up to 110 ° from a vertical axis starting in different directions is pivotal. A connection between tool spindle and tool holder allows a change of the direction of rotation of the tool. In a preferred embodiment, the machine tool is a precision grinding machine.
In einer weiteren bevorzugten Ausgestaltung ist bei der Werkzeugmaschine das Werkstück zwischen zwei Reitstockspitzen gespannt.In a further preferred embodiment, the workpiece is tensioned between two tailstock tips in the machine tool.
Weiter kann bei der Werkzeugmaschine bevorzugt der Bearbeitungsablauf am Werkstück über eine Messsensorik kontrolliert werden.Furthermore, in the case of the machine tool, the machining sequence on the workpiece can preferably be controlled via a measuring sensor system.
Als weitere bevorzugte Ausgestaltung ist das Werkstück zwischen den Reitstockspitzen mit maschinell eingestelltem Spannwert gespannt oder das Werkstück ist zwischen den Reitstockspitzen manuell positioniert gespannt.As a further preferred embodiment, the workpiece is clamped between the tailstock tips with machine-set tension value or the workpiece is clamped manually positioned between the tailstock tips.
Das erfindungsgemäße Verfahren soll nachstehend an einem Ausführungsbeispiel näher erläutert werden:The method according to the invention will be explained in more detail below using an exemplary embodiment:
Dabei zeigt:Showing:
Diese Schleifmaschine weist eine schwenkbare Schleifspindel
Beim Schwenken der Schleifspindel
Das oben beschriebene Schwenkteil
Der große Schwenkwinkelbereich ermöglicht zum einen die bereits beschriebenen Konturen gegenüber dem rotierenden Werkstück
Die wechselbaren Schleifscheiben
Durch das Weiterdrehen des Werkzeugmagazins
Eine größere Anzahl von Speicherplätzen wird durch den Einsatz eines Kettenspeichers mit Kettenglied parallel zu den Spannzangenöffnungen realisiert. Die Übergabe zur Spindelaufnahme erfolgt auf dem geraden Teilstück der Kette. Abstandsbedingt und längen- oder umfangsabhängig ist die Anzahl der Speicherplätze variabel.A larger number of memory locations is realized by the use of a chain memory with chain link parallel to the collet openings. The transfer to the spindle takes place on the straight part of the chain. Depending on the distance and the length or circumference, the number of memory locations is variable.
Ein Auswechseln des bereits verwendeten Schleifwerkzeuges
Weiter weist die Schleifmaschine einen Reitstock
Die Verfahrensweise des Reitstockeinrichtens erfolgt durch Eingabe des Spannbereiches für das zum Spannen vorgesehene Werkstück
Damit ist dem Betreiber der Maschine ein technologiegestützter Spannwert angeboten. Dieser Wert kann verwendet oder durch Eigenerfahrung verändert werden. Die zu bearbeitenden Werkstücke
Falsches oder nicht korrektes Spannen wird durch das Überschreiten der Wertvorgabe durch die Kraftmessdose erkannt und signalisiert.Incorrect or incorrect clamping is detected and signaled by the value being exceeded by the load cell.
