Abstract

The process is intended for the manufacture of grinding discs in pulverised or granular material. Instead of pressing the disc, the material is compacted by applying vacuum. The vacuum may be of different values depending on the specific requirements. The process is esp. for non-profiled or one-sidedly profiled discs. This is a simpler process giving bette rhomogeneity, bette rbalance and less wear in use.

Description

Verfahren zur Herstellung von Schleifkörpern aus pulverförmigen bisProcess for the production of grinding tools from powdery to

körnigem Ausgangsmaterial Die Erfindung betrifft ein Verfahren für die Herstellung von Schleifkörpern aus pulverförmigen bis körnigen Ausgangsmaterial insbesondere für nicht- bzw. einseitig profilierte Schleifkörper.granular starting material The invention relates to a method for the production of grinding tools from powdery to granular raw material especially for non-profiled or one-sided profiled abrasives.

Der Zweck des Verfahrens liegt in einer Qualitätsverbesserung von Schleifkörpern und in der Material- und Raumersparnis bei der notwendigen Herstellungsapparatur gegenüber den bisher üblichen Schleifkörperpressen.The purpose of the process is to improve the quality of Abrasives and in the material and space savings in the necessary manufacturing equipment compared to the previously common grinding wheel presses.

In der Schleifkörperindustrie werden neben gegossenen nur gepreßte Formteile hergestellt. Die Maschinen zur Herstellung gepreßter Schleifkörper erfordern entsprechend des benötigten Preßdruckes einen hohen Material- und Energieaufwand.In the grinding wheel industry, besides cast, only pressed ones are used Molded parts manufactured. The machines for making pressed abrasive articles require corresponding to the required pressure, a high expenditure of material and energy.

Der gepreßte Schleifkörper unterliegt einer Qualitatsminderung durch unterschiedliche Dichte das Materials, durch unterschiedlichen Verschleiß langs und quer zum Schleifkörperumfang und durch Unwucht.The pressed grinding wheel is subject to a reduction in quality different density of the material, due to different wear and tear and across the grinding wheel circumference and due to imbalance.

Der Erfindung liest die rufgabe zugrunde, die Herstellung der Schleifkörper weniger aufwendig zu gestalten und die Qualität der Schleifkörper zu erhöhen.The invention is based on the task of producing the grinding wheel to make it less complex and to increase the quality of the grinding wheel.

Diese Aufgabe wird erfindungsgemaß dadurch gelöst, daß an die Stelle des Preßverfahrens ein Verfahren zur Herstellung von Schleifkörpern aus pulverförmigen bis körnigen Ausgangsmaterial tritt, das auf dem physikalischen Prinzip der Verdichtung der Schleifkörpermasse aurch Vakuum erzielt wird, Der Grad der Evakuierung der Luft iia Verdichtungsraum hangt von den Enforderungen des Anwendungsgebietes der Schleifkörper ab. Die Erzielung des angenäherten Vakuums erfolgt nach bekannten Methoden. Insbesondere gilt cias erfindungsgemaße Verfahren für die Herstellung nicht- oder nur einseitig vorprofilierter Schleifkörper.This object is achieved according to the invention in that the place des Pressververfahren a process for the production of grinding wheels from powdery until granular starting material occurs, based on the physical principle of compaction the grinding wheel mass is achieved by vacuum, the degree of evacuation of the air The compression space depends on the requirements of the field of application of the grinding wheel away. The approximate vacuum is achieved using known methods. In particular The method according to the invention for the production does not apply on one side or on one side only pre-profiled grinding wheel.

Die mit der erfindung erzielten Vorteile bestehen insbesondere in den raum- und materialsparenden Parametern uer Maschinen zur Herstellung von Schleifkörpern und in der Qualitätsverbesserung der Schleifkörper hinsichtlich Homogenität der Masserverteilung, geringer Unwucht und geringerer Abnutzung im Nutzungsfall.The advantages achieved with the invention consist in particular in the space and material saving parameters of machines for the production of grinding tools and in improving the quality of the grinding tools with regard to the homogeneity of the Mass distribution, low imbalance and less wear and tear when in use.
