Abstract
Description
Die Erfindung betrifft ein Verfahren zur Reinigung von Schleifscheiben nach dem Oberbegriff von Anspruch 1.The invention relates to a method for cleaning Grinding wheels according to the preamble of claim 1.
Es ist bekannt, daß in Schleifprozessen verwendete Schleifscheiben während des Prozesses durch Abriebmateria lien zugesetzt werden. Diese Materialien können einerseits aus dem abgeschliffenen Material des bearbeiteten Werkstüc kes bestehen und andererseits auch Material der Schleif scheibe selbst umfassen. Die Abriebmaterialien setzen die Poren der Oberfläche der Schleifscheibe zu und verringern die Schleifleistung der Scheibe, weil die Scheibe stumpf wird. Gleichzeitig wird mit einer stumpfen Schleifscheibe die Gefahr des Schleifbrandes erhöht.It is known to be used in grinding processes Grinding wheels during the process due to abrasion material lien be added. On the one hand, these materials can from the ground material of the machined workpiece kes exist and on the other hand also material of the grinding embrace the disc itself. The abrasion materials set the Pores on the surface of the grinding wheel and reduce the grinding performance of the disc because the disc is dull becomes. At the same time with a blunt grinding wheel the risk of grinding burn increases.
Der Erfindung liegt die Aufgabe zugrunde, eine stumpf gewordene Schleifscheibe derart zu reinigen, daß eine Wei terverwendung möglich ist.The invention has for its object a blunt cleaned grinding wheel so that a Wei reuse is possible.
Die Aufgabe wird gelöst durch ein Verfahren mit den Merkmalen nach Anspruch 1.The task is solved by a procedure with the Features according to claim 1.
Ausgestaltungen sind Gegenstand von Unteransprüchen.Refinements are the subject of subclaims.
Erfindungsgemäß wird vorgeschlagen, eine stumpfe Schleifscheibe mit einem Pulverhochdruckreiniger mit einem Pulver mit sanfter Körnung zu bestrahlen. Das Profil der Schleifscheibe und die Rauhtiefe wird dadurch nicht verän dert.According to the invention, a blunt is proposed Grinding wheel with a powder pressure washer with a Irradiate powder with a gentle grit. The profile of the This does not change the grinding wheel and the surface roughness different.
Im Gegensatz zu einem Abrichten der Schleifscheibe mit einem beispielsweise diamantbesetzen Abrichtwerkzeug, läßt sich eine derart gereinigte Scheibe sofort wieder einset zen, ohne daß ein neues Einrichten der Schleifscheibe er forderlich ist. Rüstzeiten für die Maschineneinrichtung können dadurch verringert bzw. vermieden werden. Wenn der Pulverhochdruckreiniger in direkter Nähe der Schleifscheibe vorgesehen ist, kann die Schleifscheibe ohne Demontage ge reinigt werden. Entsprechende Abdichtungen zur Vermeidung von Verunreinigungen durch Pulver sind vorzusehen.In contrast to dressing the grinding wheel with a diamond-trued dressing tool, for example a disk cleaned in this way immediately resumes zen without having to set up the grinding wheel again is required. Set-up times for the machine setup can be reduced or avoided. If the Powder pressure washer in the immediate vicinity of the grinding wheel is provided, the grinding wheel can ge without disassembly be cleaned. Appropriate seals to avoid contamination by powder must be provided.
Vorzugsweise ist die Körnung des einzusetzenden Pul vers auf die Rauhtiefe der Schleifscheibe einzustellen. Eine vorteilhafte Körnung weist eine Korngröße von 0.07 bis 0.15 mm auf. Das Verfahren eignet sich insbesondere zur Reinigung von CBN-Schleifscheiben.The grain size of the pulp to be used is preferred verse to the roughness of the grinding wheel. An advantageous grain size has a grain size of 0.07 to 0.15 mm. The method is particularly suitable for Cleaning of CBN grinding wheels.
Als besonders vorteilhaft hat sich ein Glasperlenpul ver/Strahlsand herausgestellt, der üblicherweise zur Ent gratung von Zahnrädern verwendet wird. Dieses Pulver wird unter der Bezeichnung VG-620 150-250 M9 vertrieben.A glass bead pulp has proven to be particularly advantageous ver / blasting sand, which is usually used for ent burring of gears is used. This powder will sold under the name VG-620 150-250 M9.
Bei einem aus der DE-A1 43 18 102 bekannt gewordenen Schleifprozeß mit Schleifbrandvermeidung kann die Reini gung der Schleifscheiben automatisiert erfolgen, wenn der Schleifbrandvermeidungsprozeß eine zunehmende Schleif brandgefährdung erkennt. Bei einer Anordnung des Pulver hochdruckreinigers in der Nähe der Schleifscheibe wird die Scheibe gereinigt, ohne daß diese demontiert werden muß. Der Schleifprozeß läßt sich anschließend ohne Korrektur der Schleifscheibeneinstellung unter erneuter Erhöhung des Vorschubes fortsetzen.In one known from DE-A1 43 18 102 The Reini The grinding wheels are automated when the Grinding fire prevention process an increasing grinding recognizes fire hazard. With an arrangement of the powder pressure washer near the grinding wheel Glass cleaned without having to dismantle it. The grinding process can then be done without correction the grinding wheel setting while increasing the Continue feed.
Durch das erfindungsgemäße Verfahren lassen sich die Nutzungszeiten von Schleifscheiben deutlich verlängern. With the method according to the invention, the Significantly increase the useful life of grinding wheels.
Gleichzeitig sind die Maschinenkosten in Bezug auf Schei benwechsel wesentlich reduziert oder können vermieden wer den. Weiterhin ist das vorgeschlagene Verfahren umweltscho nend.At the same time, the machine costs in relation to shit benwechsel significantly reduced or avoided the. Furthermore, the proposed method is environmentally friendly named.
