Definitions
- the invention relates to a diamond form dressing roller for dressing grinding wheels with a ceramic, Bakelite or metallic bond, which carries a coating of diamonds on a surface of a base body, which is limited to the outside by the large diameter of the roller.
- Grinding disks with geometrically defined profiles on their grinding surface are used to grind profiles into workpiece surfaces. These profiles must first be worked into the new wheel by dressing and then reworked from time to time due to grinding wheel wear.
- a profile grinding wheel is dressed either with a profile dressing roller bearing the workpiece contour on its surrounding surface or with a diamond form roller.
- a form roller is also laterally guided by suitable controls during dressing so that the required grinding wheel profile stored in the control is created.
- the smallest concave radius to be dressed on the grinding wheel corresponds to the convex radius R on the diamond roller.
- Radii with R % 0.2 mm are often required.
- Suitable form rollers can either only be made with small grain diamonds or the radius R must be created on the form roller by grinding with diamond grinding wheels. With small radius sizes, however, the wear of the diamond form roller is correspondingly higher, so that the use of such dressing tools proves to be uneconomical.
- diamond form rollers have been developed, the circumferential surface of which is cylindrical.
- the diamonds lie in a layer next to one another on the cylindrical circumferential surface parallel to the axis of rotation of the tool.
- Known (DE-A 1 093 692) is a dressing tool with a diamond layer which is aligned radially to the axis of the grinding wheel. It is a fixed honing tool for dressing, which is not suitable for form dressing in the precision process, because with continuous wear the effective surface area of the diamond grit increases, so that the operating conditions change depending on wear.
- the object of the invention is therefore to make diamond shaped rollers usable for small radii over a longer service life than was previously economically possible.
- a form dressing roller according to the preamble of claim 1 which is provided only with a single coating of diamonds of narrow size, which is single-layered in the direction of the axis of rotation and multi-layered perpendicular to the axis of rotation.
- Such a form roller allows the processing of profiles with very small radii without the effective width being reduced when worn changes.
- a long service life can be used for this, because after the outer diamonds wear out, the diamonds underneath are to be used continuously until the diamond layers are completely used up under the same conditions.
- the base parts 1 and 2 with the diameter D are preferably made of steel. Between the base body parts 1 and 2 is the single layer in the direction of the axis of rotation 3 and perpendicular to the axis of rotation 3 multilayer diamond coating 4 with the thickness D 1 with the diamonds 5 located on the outermost circumference generate, be closely classified by sieving.
- a sieve fraction can be used which has passed a sieve with a mesh size of 330 ⁇ m, but remains on a sieve with a mesh size of 290 4 m.
- the sieve fraction can be grain-size classified in a known manner and only the predominantly round or blocky grains can be used.
- the steel base bodies 1 and 2 are simultaneously ground down by contact with the grinding wheel, so that the diamonds available on the outer circumference always protrude beyond the base body because the diamonds wear less because of their hardness as the steel base bodies 1 and 2 and the bond 6 arranged between the diamonds.
- a state of wear 7 is shown in dashed lines as an example because of the successively engaging, diamond-tipped circumferences up to the dash-dotted line 8, but with the pointed shape of the diamond form roller remains, the lifespan of this dressing tool is far longer than the lifespan of known diamond form rollers, in which the wear after usually only half a diamond coating layer brings about the end of the lifespan due to an impermissibly large form deviation.
- the diamonds are advantageously bound to the base part 1 by means of an electrodeposited nickel coating, the thickness of which is smaller than the diamond grain size.
- other types of binding such as bronze, steel, synthetic resin and the like can also be used.
- a double bond can preferably also be carried out, the single-layer diamond coating being bonded to one base part by galvanic precipitation, but the other base part is sintered, for example, with a bronze, which can optionally be filled with wear-reducing fillers such as cobalt.
- a further embodiment consists in that the base body part 2 is made of sintered bronze, the sintered bronze being sintered directly onto the base body part 1 equipped with the diamond coating.

Abstract
Description
Die Erfindung betrifft eine Diamant-Formabrichtrolle zum Abrichten von Schleifscheiben mit keramischer, bakelitischer oder metallischer Bindung, die auf einer Fläche eines Grundkörpers, welche nach außen durch den Größtdurchmesser der Rolle begrenzt ist, einen Belag aus Diamanten trägt.The invention relates to a diamond form dressing roller for dressing grinding wheels with a ceramic, Bakelite or metallic bond, which carries a coating of diamonds on a surface of a base body, which is limited to the outside by the large diameter of the roller.
Zum Einschleifen von Profilen in Werkstückoberflächen werden Schleifscheiben verwendet, die auf ihrer Schleiffläche geometrisch definierte Profile aufweisen. Diese Profile müssen durch ein Abrichten zunächst in die neue Scheibe eingearbeitet und danach wegen eines Schleifscheibenverschleißes von Zeit zu Zeit nachbearbeitet werden.Grinding disks with geometrically defined profiles on their grinding surface are used to grind profiles into workpiece surfaces. These profiles must first be worked into the new wheel by dressing and then reworked from time to time due to grinding wheel wear.
Das Abrichten einer Profilschleifscheibe erfolgt entweder mit einer Profilabrichtrolle, die auf ihrer Umfläche die Werkstück-Kontur trägt, oder mit einer Diamant-Formrolle. Eine Formrolle wird durch geeignete Steuerungen beim Abrichten auch seitlich so geführt, daß das erforderliche in der Steuerung gespeicherte Schleifscheibenprofil entsteht.A profile grinding wheel is dressed either with a profile dressing roller bearing the workpiece contour on its surrounding surface or with a diamond form roller. A form roller is also laterally guided by suitable controls during dressing so that the required grinding wheel profile stored in the control is created.
Der kleinste abzurichtende konkave Radius an der Schleifscheibe entspricht dem konvexen Radius R an der Diamant-Formrolle. Häufig werden Radien mit R % 0,2 mm gefordert. Dafür geeignete Formrollen können entweder nur mit Diamanten von kleiner Körnungsgröße hergestellt sein oder der Radius R muß an der Formrolle durch Schleifen mit Diamant-Schleifscheiben erzeugt werden. Bei kleinen Radiusgrößen ist der Verschleiß der Diamant-Formrolle jedoch entsprechend höher, so daß sich der Einsatz solcher Abrichtwerkzeuge als unwirtschaftlich erweist.The smallest concave radius to be dressed on the grinding wheel corresponds to the convex radius R on the diamond roller. Radii with R % 0.2 mm are often required. Suitable form rollers can either only be made with small grain diamonds or the radius R must be created on the form roller by grinding with diamond grinding wheels. With small radius sizes, however, the wear of the diamond form roller is correspondingly higher, so that the use of such dressing tools proves to be uneconomical.
Deshalb sind Diamant-Formrollen entwickelt worden, deren Umfläche zylinderförmig ist. Der Zylinderteil wird an beiden Seiten durch Radien begrenzt, die wiederum tangential in z. B. unter einem Winkel a = 30° geneigte Stirnflächen übergehen. Bei diesen Formrollen liegen die Diamanten auf der zylindrischen Umfangsfläche parallel zu der Drehachse des Werkzeuges in einer Schicht nebeneinander.That is why diamond form rollers have been developed, the circumferential surface of which is cylindrical. The cylinder part is delimited on both sides by radii, which in turn are tangential in z. B. pass at an angle a = 30 ° inclined end faces. With these form rollers, the diamonds lie in a layer next to one another on the cylindrical circumferential surface parallel to the axis of rotation of the tool.
Für diese können bei gleichem Radius R wegen ihrer geometrischen Form größere Körnungsgrö- ßen verwendet werden als bei der vorher beschriebenen Ausführungsform. Wegen der zusätzlichen geraden Abrichtzonen kommen gleichzeitig mehrere Diamanten zum Einsatz. Dadurch wird die Lebensdauer verlängert. Die Verwendung derartiger Rollen ist jedoch durch ihre geometrische Form eingeschränkt, weil nur konkave Radien mit eingeschlossenem Winkel -- 90° bzw . 90° + a abgerichtet werden können. Außerdem sind derartige Diamant-Formrollen durch den am Radius auftretenden Verschleiß noch mit unzureichender Lebensdauer behaftet, weil beim Profilabrichten im Dereich des Radius R der häufigste Kontakt und damit die größte Belastung auftritt. Alle diese bekannten Formrollen haben den Nachteil, daß ihre Lebensdauer spätestens dann erreicht ist, wenn eine Schicht Diamanten verschlissen ist.Larger grain sizes can be used for these at the same radius R because of their geometric shape than in the previously described embodiment. Because of the additional straight dressing zones, several diamonds are used at the same time. This extends the lifespan. However, the use of such rollers is limited by their geometric shape, because only concave radii with an included angle - 90 ° or. 90 ° + a can be dressed. In addition, such diamond form rollers are still subject to an inadequate service life due to the wear occurring on the radius, because the most frequent contact and thus the greatest stress occurs during profile dressing in the area of the radius R. All these known form rollers have the disadvantage that their service life is at the latest when a layer of diamonds is worn out.
Bekannt (DE-A 1 093 692) ist ein Abrichtwerkzeug mit einer Diamantschicht, die radial zu der Achse der Schleifscheibe ausgerichtet ist. Dabei handelt es sich um ein feststehendes Abziehwerkzeug zum Abrichten, das für ein Formabrichten im Präzisionsverfahren nicht geeignet ist, weil sich mit fortlaufendem Verschleiß auch die wirksame Angriffsfläche der Diamantkörnung vergrößert, so daß sich die Einsatzbedingungen in Abhängigkeit vom Verschleiß fortlaufend ändern.Known (DE-A 1 093 692) is a dressing tool with a diamond layer which is aligned radially to the axis of the grinding wheel. It is a fixed honing tool for dressing, which is not suitable for form dressing in the precision process, because with continuous wear the effective surface area of the diamond grit increases, so that the operating conditions change depending on wear.
Der Nachteil einer nur geringen Lebensdauer einer Formabrichtrolle ist auch gegeben bei einer bekannten Ausführung entsprechend der DE-A 2 510 558 welche den nächstkommenden Stand der Technik beschreibt. Eine solche Abrichtrolle trägt auf zwei nach außen hin konvergierenden ebenen Flächen sowie auf ihrer Konvex gekrümmten Scheibenumfangsfläche einen Diamantbelag, der einschichtig ausgebildet ist. Wenn mit einer derartigen Formrolle das Abrichten einer Schleifscheibe mit ihrer Umfangsfläche erfolgt, ist die Lebensdauer bzw. der Erhalt genauer Abrichtergebnisse beschränkt auf den Erhalt der an der Umfangsfläche liegenden äußersten Diamantschicht, die einschichtig ist. Nach einem Verbrauch der außen am Umfang liegenden Diamantschicht würden zwar die beiden sich außen anschließenden und nach außen hin divergierenden Diamantschichten noch zum Einsatz kommen, obwohl diese ansich dafür bestimmt sind, durch ein Schwenken der Formrolle am abzurichtenden Werkzeug Schultern frei zu arbeiten. Aufgrund der mit dem fortschreitenden Verbrauch der außenliegenden Schichten zunehmenden Divergenz können aber nicht fortlaufend Radien gleicher Größe genutzt werden, weil die Größe der wirksamen Radien fortlaufend zunehmen würde, da sich der ursprünglich vorhandene kleine Außenradius der Formabrichtrolle fortlaufend vergrößert in Folge der gegenseitigen Schrägstellung der beiden außenliegenden Diamantschichten. Nach einem Verschleiß der ursprünglich am Umfang außen liegenden Diamantkornschicht ist es demzufolge nicht möglich, weiterhin gleichbleibend kleine Radien auf der Schleifscheibe zu erzeugen unter einer weiterhin langzeitigen Ausnutzung der Formabrichtrolle.The disadvantage of only a short life of a form dressing roll is also given in a known embodiment according to DE-A 2 510 558 which describes the closest prior art. Such a dressing roller has a diamond coating on two outwardly converging flat surfaces and on its convexly curved peripheral surface, which is formed in one layer. If such a form roller is used to dress a grinding wheel with its peripheral surface, the service life or the obtaining of precise dressing results is limited to the preservation of the outermost diamond layer on the peripheral surface, which is a single layer. After the diamond layer lying on the outside of the circumference has been used up, the two diamond layers adjoining on the outside and diverging towards the outside would still be used, although these are in themselves intended to work freely by swiveling the shaping roller on the tool to be dressed. However, due to the increasing divergence with the increasing consumption of the outer layers, radii of the same size cannot be used continuously, because the size of the effective radii would increase continuously, since the originally small outer radius of the dressing roll increases continuously as a result of the mutual inclination of the two outer ones Layers of diamond. After the diamond grain layer, which was originally on the circumference, has worn out, it is consequently not possible to continue to produce constantly small radii on the grinding wheel while the form dressing roller is still used for a long time.
Der Erfindung liegt von daher die Aufgabe zugrunde, Diamant-Formrollen für kleine Radien über eine längere Lebensdauer verwendbar zu machen, als es bisher wirtschaftlich möglich erschien. Erfindungsgemäß ist dafür eine Formabrichtrolle nach dem Oberbegriff des Anspruches 1 vorgesehen, die nur mit einem einzigen Belag von Diamanten engklassierter Grösse versehen ist, der in Richtung der Drehachse einschichtig und senkrecht zu der Drehachse mehrschichtig ist.The object of the invention is therefore to make diamond shaped rollers usable for small radii over a longer service life than was previously economically possible. According to the invention there is provided a form dressing roller according to the preamble of claim 1, which is provided only with a single coating of diamonds of narrow size, which is single-layered in the direction of the axis of rotation and multi-layered perpendicular to the axis of rotation.
Eine derartige Formrolle erlaubt die Bearbeitung von Profilen mit sehr kleinen Radien, ohne daß sich bei ihrem Verschleiß die wirksame Breite ändert. Dazu kann eine lange Lebensdauer ausgenutzt werden, weil nach einem Verschleiß der außenliegenden Diamanten fortlaufend die darunterliegenden Diamanten bis zum vollständigen Aufgebrauch der Diamantschichten unter gleich bleibenden Bedingungen auszunutzen sind.Such a form roller allows the processing of profiles with very small radii without the effective width being reduced when worn changes. A long service life can be used for this, because after the outer diamonds wear out, the diamonds underneath are to be used continuously until the diamond layers are completely used up under the same conditions.
Ein Ausfuhrungsbeispiel einer solchen Diamant-Formrolle ist in einer Zeichnung wiedergegeben und nachstehend erläutert.An exemplary embodiment of such a diamond form roller is shown in a drawing and explained below.
Die Grundkörperteile 1 und 2 mit dem Durchmesser D bestehen vorzugsweise aus Stahl. Zwischen den Grundkörperteilen 1 und 2 liegt der in Richtung der Drehachse 3 einschichtige und senkrecht zur Drehachse 3 mehrschichtige Diamantbelag 4 von der Stärke D1 mit den auf dem äußersten Umkreis befindlichen Diamanten 5. Die Diamanten können, um einen definierten Radius R mit enger Toleranz zu erzeugen, durch Sieben eng klassiert sein. Zum Beispiel kann eine Siebfraktion Verwendung finden, die ein Sieb mit der Maschenöffnungsweite 330 µm passiert hat, jedoch auf einem Sieb mit einer Maschenöffnungsweite von 290 4m liegen bleibt. Darüberhinaus kann zur weiteren Einengung der Toleranz die Siebfraktion in bekannter Weise kornformklassiert und nur die überwiegend runden oder blockigen Körner verwendet werden. Verschleißt die äußerste Diamantschicht 5 beim Abrichten, dann werden die Stahlgrundkörper 1 und 2 durch den Kontakt mit der Schleifscheibe gleichzeitig abgeschliffen, so daß die jeweils auf dem äußersten Umfang zur Verfügung stehenden Diamanten immer über den Grundkörper hinausragen, weil die Diamanten wegen ihrer Härte weniger verschleißen als die Stahlgrundkörper 1 und 2 und die zwischen den Diamanten angeordnete Bindung 6. Ein Verschleißzustand 7 ist als Beispiel gestrichelt eingezeichnet Aufgrund der nacheinander zum Eingriff gelangenden, diamantbestückten Umkreise bis zur gestricht-punktierten Linie 8, wobei jedoch die spitze Form der Diamant-Formrolle erhalten bleibt, ist die Lebensdauer dieses Abrichtwerkzeuges weit größer als die Lebensdauer bekannter Diamant-Formrollen, bei denen der Verschleiß nach meist nur einer halben Diamantbelagschicht bereits das Ende der Lebensdauer durch unzulässig große Formabweichung herbeiführt.The base parts 1 and 2 with the diameter D are preferably made of steel. Between the base body parts 1 and 2 is the single layer in the direction of the axis of
Die Bindung der Diamanten an den Grundkörperteil 1 erfolgt vorteilhaft durch einen galvanisch abgeschiedenen Nickelbelag, dessen Dicke kleiner ist als die Diamantkörnungsgröße. Verwendbar sind jedoch ebenfalls andere Bindungsarten wie Bronze, Stahl, Kunstharz und ähnliche. Vorzugsweise kann auch eine doppelte Bindung erfolgen, wobei der einschichtige Diamantbelag auf den einen Grundkörperteil durch einen galvanischen Niederschlag gebunden ist, der andere Grundkörperteil jedoch zum Beispiel mit einer Bronze, die gegebenenfalls mit verschleißmindernden Füllstoffen wie Kobalt aufgefüllt werden kann, aufgesintert wird. Eine weitere Ausführungsform besteht darin, daß der Grundkörperteil 2 aus Sinterbronze gefertigt ist, wobei die Sinterbronze direkt auf den mit dem Diamantbelag bestückten Grundkörperteil 1 aufgesintert wird.The diamonds are advantageously bound to the base part 1 by means of an electrodeposited nickel coating, the thickness of which is smaller than the diamond grain size. However, other types of binding such as bronze, steel, synthetic resin and the like can also be used. A double bond can preferably also be carried out, the single-layer diamond coating being bonded to one base part by galvanic precipitation, but the other base part is sintered, for example, with a bronze, which can optionally be filled with wear-reducing fillers such as cobalt. A further embodiment consists in that the base body part 2 is made of sintered bronze, the sintered bronze being sintered directly onto the base body part 1 equipped with the diamond coating.
