Abstract
Description
Anwendung von flüssigen oder gasförmigen TiefkühimittelnUse of liquid or gaseous frozen foods
zur Kehlung bei mechanischer Bearbeitung durch Schleifen Die Erfindung betrifft ein Verfahren zur Kühlung der sehr hohen Schneidentemperaturen an der Schnittstelle eines Schleifkörpers beim Schleifen der verschiedensten Werkstoffe.for grooves in mechanical processing by grinding The invention relates to a method for cooling the very high cutting edge temperatures at the interface of a grinding tool when grinding a wide variety of materials.
Die bisher angewandten Kühiverfahren beim Schleifen bestehen in Kühlen mit Wasser, Ölen, Emulsionen. Diese Kühlmittel beinhalten den Nachteil, daß sie durch die hohen Temperaturen an der Schnittstelle nur noch im dampfförmigen Zustand vorliegen und dabei ein Temperaturniveau mit minderer KUhlwirkung erlangen. In Girenzfällen kommt es durch diese hohen Temperaturen zu unerwünschten Anlaßeffekten. Es kommt auch vor, daß durch die noch relativ hohen Temperaturen, die an der jeweiligen Stelle nur kurzzeitig auftreten, Spannungen entstehen, die zu Rissen im Werkstoff fUhren. Bei anderen Materialien entstehen Brandstellen oder Risse. Die bei den Schleifkörpern an der Schnittstelle entstehenden hohen Temperaturen wirken sich auf die Standzeit der Schleifkörper sehr negativ aus. Die SchleiF-körper stumpfen schnell ab, wodurch die Reibung erhöht wird und wiederum eine Terflperatursteigewng zur Folge hat.The cooling methods used to date in grinding consist of cooling with water, oils, emulsions. These coolants have the disadvantage that they due to the high temperatures at the interface only in the vaporous state are present and thereby achieve a temperature level with less cooling effect. In Girenz cases These high temperatures lead to undesirable tempering effects. It is coming also before that due to the still relatively high temperatures at the respective point occur only briefly, tensions arise that lead to cracks in the material. Other materials cause burns or cracks. The one with the grinding tools The high temperatures occurring at the interface affect the service life the grinding wheel looks very negative. The abrasive bodies quickly become blunt, causing the friction is increased and in turn leads to a rise in temperature.
Aufgabe der Erfindung ist es, eine Kühlung zu schaffen, welche die vorerwähnfen Nachteile nicht aufweist, sondern diese mit geringst möglichem Aufwand beseitigt und eine Leistungssteigerung durch Verlöngerung der Lebensdauer der Schleifkörper bringt.The object of the invention is to create a cooling system which the previously mentioned does not have disadvantages, but these with the least possible effort eliminated and an increase in performance by extending the service life of the grinding tools brings.
Die in Figur 1 dargestellte Erfindung besteht darin, daß flüssige oder gasförmige Tiefkühlmittel 4 so nahe wie möglich an die Schnittstelle gebracht werden.The invention shown in Figure 1 is that liquid or gaseous refrigerants 4 brought as close as possible to the interface will.
Die niedrige Verdampfunjs#temperatur, die bei ca. -70 0C liegt, ist damit um ca. 400 % tiefer als die Temperatur der herkömmlichen Küh!mittel.The low evaporation temperature, which is around -70 ° C, is to approx. 400% lower than the temperature of conventional coolants.
Das Tiefkühimittel 4 kann von außen an den Sckleifkörper herongefilhrf werden, wie auch durch diesen selbst. Das Tiefkühlrrlittel 4 wird so an die Schnittstelle geführt, daß diese im Bereich der niedrigsten Verdampfungstemperatur 2 liegt.The deep-freezing means 4 can be attached to the grinding body from the outside as well as by this itself. The deep-freeze means 4 is thus at the interface led that this is in the range of the lowest evaporation temperature 2.
Die Erfindung sieht vor, daß das Tiefkuhlmittel 4 auch von verschiedenen Seiten an die Schnittstelle gefuhrt werden kann, um diese in den Bereich der niedrigsten Verdampfungstemperatur 2 zu bringen.The invention provides that the refrigerant 4 also of different Pages to the interface can be brought to this in the area of the lowest Bring evaporation temperature 2.
Diese Erfindung bewirkt somit, daß keinerlei Anlaß-, Riß- oder Brennerscheinungen bei den verschiedenen Werkstoffen und Werkstücken 3 entstehen, die Lebensdauer der Schfeifkörper 1 sich erhöht und daß sich wesentlich hohere Schnittleistungen ergeben bzw. bei gleicher Schnitilektung für den Schleifk#rper 1 die Antriebsleistung erheblich gesenkt wird.This invention thus has the effect that no tempering, cracking or burning phenomena whatsoever arise in the various materials and workpieces 3, the service life of the Sharp body 1 increases and that there are much higher cutting capacities or with the same cutting effect for the grinding wheel 1, the drive power is considerable is lowered.
