Description

Herstellung von Schleifscheiben unter Verwendung eines aus Harzlösung bestehenden Bindemittels. Man bat bereits vorgeschlagen, das Schleifkorn bei Schleifscheiben in doppelter Weise dadurch zu binden, daß man das das Schleifkorn zusammenhaltende Gerippe aus einer Silikatbindung herstellt und dieses mit einer unschmelzbaren Harzlösung härtet. Die Tränkung mit der Harzlösung oder -flüssigkeit erfolgt hierbei aber unter Füllung der Öffnungen des Gerippes. Derartige Schleifscheiben sind daher für Hochleistungsarbeiten nicht verwendbar, weil sich der Span nicht leicht bilden und frei entwickeln kann.Manufacture of grinding wheels using a resin solution existing binder. It has already been suggested that the abrasive grain be used for grinding wheels to bind in a double way in that one holds the abrasive grain together Manufactures framework from a silicate bond and this with an infusible resin solution hardens. However, the impregnation with the resin solution or liquid takes place below Filling of the openings in the framework. Such grinding wheels are therefore for high-performance work not usable because the chip cannot easily form and develop freely.

Demgegenüber beruht das Wesen der Erfindung in einer derartigen Behandlung des aus einer Magnesit-, Silikatbindung o. dgl. des Schleifkornes gebildeten Gerippes der Schleifscheibe, daß das Gerippe mit der unschmelzbaren Harzlösung, wie Bakelite, derart überzogen wird, daß die Poren des Gerippes offen bleiben, was durch. deren Verwendung in beliebig dünner (Spiritus-)Lö ung erreicht wird. Danach wird die Scheibe zunächst an der Luft getrocknet und dann bei der erforderlichen Temperatur im Ofen fertig gehärtet. Auf diese Weise entstehen hochporöse Schleifscheiben von durch Verdünnung der Lösung oder die Zahl der Auftragungen genau regelbarer und durch die ganze Schleifschicht gleichbleibender Härte (Bindungsfestigkeit ) bei äußerst sparsamem Verbrauch an teuerem Harz.In contrast, the essence of the invention resides in such a treatment of the framework formed from a magnesite, silicate bond or the like of the abrasive grain the grinding wheel that the skeleton with the infusible resin solution, such as Bakelite, is coated in such a way that the pores of the skeleton remain open, which is through. whose Use in any thin (spirit) solution is achieved. After that the disc first air-dried and then in the oven at the required temperature hardened. In this way, highly porous grinding wheels are created by Dilution of the solution or the number of applications can be precisely controlled and through the entire abrasive layer of constant hardness (bond strength) with extremely economical consumption of expensive resin.
