Die Herstellung kunstharzgebundener Schleifkörper in einer zunächst nur mit Schleifkorn gefüllten Form, in die anschließend das flüssige Harzbindemittel zugegeben wird, erfolgt nach dem Verfahren der Patentanmeldung O3080Ib/67c in der Weise, daß das Schleifkorn einer an sich bekannten Verdichtung, z. B. durch Vibrationen und nachfolgende Pressung, unterzogen und dann das Kunstharzbindemittel aus Düsen der mit Entlüftungskanälen versehenen Form in die Hohlräume des Kornskelettes eingespritzt wird. Nach diesem Verfahren werden Schleifkörper mit einem sehr festen Gefüge erhalten; die Schleif körner liegen so dicht aneinander, daß sie sich nicht gegeneinander verschieben können. Um einen solchen Körper trotz des dichten Schleifkornskelettes ein poröses Gefüge zu geben, wird gemäß der Erfindung als Kunstharzbindemittel ein Schaumkunststoff verwendet und gegebenenfalls das bei Schaumkunststoffen übliche Treibmittel bereits mit dem Schleifkorn in die Form gegeben.The production of synthetic resin-bonded abrasives in a form initially only filled with abrasive grain, into which the liquid resin binder is then added, takes place according to the method of the patent application O3080Ib / 67c in such a way that the abrasive grain of a per se known compaction, e.g. B. by vibration and subsequent pressing, subjected and then the resin binder from nozzles the mold provided with ventilation channels is injected into the cavities of the grain skeleton. To This process produces abrasive articles with a very firm structure; the abrasive grains are lying so close to each other that they cannot move against each other. To such a body in spite of To give the dense abrasive grain skeleton a porous structure is used according to the invention as a synthetic resin binder a foam plastic is used and optionally the propellant customary for foam plastics already put into the mold with the abrasive grain.

Starre Schleifkörper mit künstlich erzeugter Porosität sind an sich bekannt. So erhält man einen umlaufenden Schleifkörper von starrer Beschaffenheit mit künstlicher Porosität, bestehend aus Schleifmaterial und Bindemittel, dadurch, daß eine Preßform mit z. B. kugeligen, durch Maßnahmen wieLösen, Schmelzen, Verdampfen od. dgl. wieder entfernbaren Körpern gefüllt, die Zwischenräume mit einem Gemisch von Schleifmaterial und Bindemitteln ausgefüllt, das Ganze verfestigt und nach Verfestigung die Kugeln entfernt werden. Nach einer anderen Methode erfolgt die Herstellung von umlaufenden Schleifkörpern starrer Beschaffenheit mit künstlicher Porosität durch Anwendung des für die Herstellung poröser Kunststeine bekannten Gastreibeverfahrens in der Weise, daß man aus Schleifmaterial, Bindemitteln und zur Gasentwicklung befähigten Stoffen plastische formbare Massen herstellt, diese durch Entwickeln von Gasblasen mit Hohlräumen gewünschter Größenordnung durchsetzt und die Formkörper alsdann durch A^erfestigung in Schleifkörper von zellförmiger Struktür überführt.Rigid grinding bodies with artificially created porosity are known per se. So you get a revolving one Rigid abrasive articles with artificial porosity, consisting of abrasive material and binders, in that a mold with e.g. B. spherical, by measures such as loosening, melting, Evaporation od. The like. Removable bodies filled, the interstices with a mixture filled with abrasive material and binding agents, the whole solidified and after solidification the balls removed. Another method is used to manufacture rotating grinding tools rigid nature with artificial porosity by using the for the production of porous artificial stones known gas driving process in such a way that one of abrasive material, binders and for Gas development-capable substances produces plastic, malleable masses, these by developing Gas bubbles interspersed with cavities of the desired size and the shaped bodies then through A ^ hardening transferred to abrasive bodies with a cellular structure.

Nach einem weiteren bekannten Vorschlag werden zur Bindung der Schleifkörner Kunststoffe in Mischung mit Weichmachern in Form von Lösungen und Emulsionen verwendet und diese nur in solchen Mengen mit den Schleifkörnern vermischt, daß bei der formgebenden Pressung zwischen den Körnern noch Poren frei bleiben und die Preßlinge vorübergehend auf diejenigen Temperaturen gebracht werden, bei denen die gegenseitige Lösung der Weichmacher und der Kunststoffe eintritt. Nach dem Abkühlen sind hochelastische, poröse Schleifkörper entstanden, deren Schleifkörner ganz oder teilweise mit Kunstharz überzogen und aneinander gebunden sind.According to another known proposal, a mixture of plastics is used to bond the abrasive grains used with plasticizers in the form of solutions and emulsions and these only in such Amounts mixed with the abrasive grains that during the shaping pressing between the grains pores still remain free and the compacts are temporarily brought to the temperatures in which the mutual dissolution of the plasticizers and the plastics occurs. After cooling down are Highly elastic, porous abrasive bodies were created, the abrasive grains of which were completely or partially coated with synthetic resin and are bound to each other.

Ferner ist eine Schleifscheibe bekanntgeworden, deren Schleifkörper in ein schwammiges Material gebunden sind. Zum Stand der Technik gehören demnach kunstharzgebundene Schleifkörper, die nach Art eines Schwammgefüges vielporig sind. Die bekannten Schleifkörper haben indes nicht das dichte Schleifkornskelett wie die nach dem Verfahren der Patentanmeldung O 3080 Ib/67c hergestellten Schleifkörper, so daß die Anwendung eines Schaumkunststoffes für dieses Verfahren ein besonders einfaches Mittel ist, um einen Schleifkörper zu erhalten, der trotz seines starren Gefüges auch porös ist.Furthermore, a grinding wheel has become known, the grinding body of which is bound in a spongy material are. The state of the art therefore includes synthetic resin-bonded grinding tools, which, according to Art of a sponge structure are multi-pored. The known abrasive bodies, however, do not have the dense abrasive grain skeleton like those according to the method of the patent application O 3080 Ib / 67c manufactured abrasive, so that the application of a foam plastic for this method is a particularly simple means of obtaining an abrasive which, in spite of its rigid structure is also porous.
