Description

Schneidesüssigkeit für die spanabhebende Verformung von Aluminium und dessen Legierungen Gegenstand der Erfindung ist eigie Schneidflüssigkeit für Verfahren zur spanabhebenden Verformung von Aluminium und dessen Le= gierungen. Es hat sich nämlich gezeigt, daß man durch geeignete Wahl der Schneidflüssigkeit beim spanabhebenden Bearbeiten, wie Drehen und Bohren, von Aluminium oder dessen Legierungen überraschende Verbesserungen erzielen kann.Cutting fluid for the metal-cutting deformation of aluminum and its alloys. The subject of the invention is cutting fluid for Process for the metal-cutting deformation of aluminum and its alloys. It has been shown that by a suitable choice of the cutting fluid when machining, such as turning and drilling, of aluminum or its Alloys can achieve surprising improvements.

Versuche haben ergeben, daß als Schneidflüssigkeiten wäßrige alkalische Chromatlösungen, wie sie für die chemische Oberflächenbehandlung von '.Metallen verwendet werden, besonders gute Ergebnisse zeitigen. Diese Lösungen können, als solche oder in Gemischen mit Ölen angewandt werden.Tests have shown that aqueous alkaline cutting fluids are used Chromate solutions such as those used for the chemical surface treatment of metals used, produce particularly good results. These solutions can, as such or in mixtures with oils.

Die Vorteile, die mit solchen Schneidflüssigkeiten zu erzielen sind, sind mehrfacher Art.-Bei dem Verfahren gemäß Erfindung ist die Haltbarkeit des Werkzeuges verlängert, die Verbesserung der Schneidhaltigkeit hat eine bessere Maßhaltigkeit des Werkstückes zur Folge. Ein Nachschleifen des Stahles ist viel seltener nötig bei gleicher Güte des abgedrehten Werkstückes.The advantages that can be achieved with such cutting fluids are multiple art. In the method according to the invention, the durability of the tool extended, the improvement in edge retention has better dimensional accuracy of the workpiece. A regrinding of the steel is required much less often with the same quality of the machined workpiece.

Außerdem ist eine höhere Schnittgeschwindigkeit ohne Überbeanspruchung des Stahles möglich bzw. größerer Vorschub oder größere Spantiefe.In addition, a higher cutting speed is without overuse of the steel possible or greater feed rate or greater depth of cut.

Folgende Beispiele mögen die durch die Erfindung erzielten Vorteile dartun. Bearbeitet wurde ein Block aus einer Aluminium-Silicium-Legierung mit 13 % Silicium und o,3 0!o Magnesium, wobei als Drehstahl ein solcher aus gehärtetem Kohlenstoffstahl benutzt--wurde. Die Versuche wurden bei. Drehgeschwindigkeiten, die infolge- der Durchmesserabnahme zwischen 140 und 128m je Minute schwankten; durchgeführt. Der Vorschub betrug., o,25 nim je Umdrehung, die Spanti@fe 2 min. Die nachstehend angegebenen Drehlängen be-, zeichnen die Gesamtverschiebung des Sup- -ports während eines Versuches, also nicht die Spanlängen.The following examples like the advantages achieved by the invention to show. A block made of an aluminum-silicon alloy with 13 was machined % Silicon and o, 3 0! O magnesium, the turning steel being a hardened one Carbon steel used - was. The trials were at. Rotation speeds, which fluctuated between 140 and 128 m per minute as a result of the decrease in diameter; carried out. The advance was .0.25 nim per revolution, the Spanti @ fe 2 min. The turning lengths given below denote the total displacement of the Sup- -ports during an attempt, so not the chip lengths.

Zum Vergleich mit dem Verfahren der Erfindung wurden zwei Versuche mit dem üblichen Bohröl ausgeführt. Das erstemal versagte der Stahl nach 125 mm D,rehläng,e dadurch, daß sich ein Span an diefäshe4e angesetzt hatte; der Span wurde entfernt. Nach 5 mm versagte der Span schon wieder aus dem gleichen Grunde. Bei einem zweiten Versuch mußten bei 115, 18o, 235 und 265 mm Späne entfernt werden. Der Stahl lief jedoch jedesmal noch notdürftig. Im praktischen Betrieb hätte man ihn allerdings schon das erstemal geschliffen. Bei etwa 30o mm Drehlänge versagte er endgültig.For comparison with the method of the invention, two tests were carried out with the usual drilling oil. The first time the steel failed after a diameter of 125 mm, lengthwise, because a chip had attached itself to the barrel; the chip has been removed. After 5 mm, the chip failed again for the same reason. In a second attempt, chips had to be removed at 115, 18o, 235 and 265 mm. However, the steel still ran poorly every time. In practical operation, however, it would have been sharpened for the first time. At about 30o mm turning length it finally failed.

Diesen Beispielen gegenüber zeigt das folgende die gemäß Erfindung erzielten Vorteile Als Schneidflüssigkeit wurde eine wäßrige Lösung von 5 % calcinierter Soda und i, 5 0lo Natriumchromat in Wasser angewandt. Der Stahl lief ohne Schwierigkeiten i ioo mm lang. Die Späne liefen gut ab. Die bearbeitete Oberfläche war bei diesem Schmiermittel am glattesten. Dann wurde die Schneide allmählich stumpf. Bei - etwa i3oo mm zog die Maschine nicht mehr richtig durch, so daß man den Stahl hätte nachschleifen müssen. Immerhin wäre ein Weiterdrehen noch möglich gewesen.In contrast to these examples, the following shows those according to the invention Achieved advantages An aqueous solution of 5% calcined was used as the cutting fluid Soda and 1.5 0lo sodium chromate applied in water. The steel ran without difficulty ioo mm long. The chips ran off well. The machined surface was on this one Lubricants the smoothest. Then the edge gradually became blunt. At - about The machine no longer pulled through 300 mm so that the steel would have to be regrinded have to. At least it would have been possible to continue turning.

Während bei Bohröl die Schneide unregelmäßig abgenutzt war und die Schneidhaltigkeit anscheinend auch durch angeschweißte Aluminiumstückchen beeinträchtigt wurde, war bei dem Beispiel gemäß Erfindung zum _; Schluß des Versuches die Schneide ganz gleichmäßig abgenutzt, so daß sie gegen Ende 4es 'Versuches um einige Zehntelmillimeter tiefer und etwas vom Stück weg versetzt war. Sie war aber immer noch verhältnismäßig scharf und blank.While with drilling oil the cutting edge was worn irregularly and the Edge retention apparently also impaired by welded-on pieces of aluminum was, was in the example according to the invention to _; End of the attempt the cutting edge worn quite evenly, so that towards the end of the 4th attempt it was a few tenths of a millimeter was deeper and slightly offset from the piece. But it was still proportionate sharp and shiny.

Es können auch andere wäßrige alkalische Chromatlösungen verwendet werden, beispielsweise solche mit 15 g Natriumchromat und 5 g Ätznatron im Liter oder mit 15g Natriumchromat und 40 g Kaliumcarbonat im Liter.Other aqueous alkaline chromate solutions can also be used be, for example those with 15 g sodium chromate and 5 g caustic soda per liter or with 15g sodium chromate and 40 g potassium carbonate per liter.

Es ist schon vorgeschlagen worden, bei der Metallbearbeitung zur Kühlung und Schmierung wäßrige/ Sodalösu:ngen zu verwenden, und zwar ist dieses Mittel in erster Linie für die Bearbeitung von Eisen und Stahl vorgeschlagen. Diesem Bekannten gegenüber bringt die gemeinsame Venvendttng von Soda und Chromat eine überraschende Steigerung der Wirkung hinsichtlich der Schneiderleichterung.It has already been proposed in metalworking for cooling and lubrication aqueous / soda solutions to use, namely this agent is in suggested primarily for working iron and steel. This friend on the other hand, the joint use of soda and chromate is surprising Increasing the effect in terms of making it easier to cut.
