Description

Bei der Vorrichtung mit umlaufendem Werkzeug zum Nachschleifen von Körnerspitzen nach Patent 323871 ist die Schleif-. scheibenwelle parallel zum Zentrierkonus ■ gelagert, und die Schleifscheibe arbeitet mit : einer konischen Mantelfläche.In the device with a rotating tool for regrinding grain tips according to patent 323871, the grinding. disk shaft parallel to the centering cone ■ and the grinding wheel works with : a conical outer surface.

Bei dieser Ausführung sind die Verhältnisse für das Arbeiten der Schleifscheibe inso- ; fern ungünstig, als von den Schleifflächen- ; In this version, the conditions for the work of the grinding wheel are inso-; far more unfavorable than from the grinding surface ;

" zonen der Schleifscheibe, die ungleiche
Umfangsgeschwindigkeit wegen ihrer Konus- \ form haben, gerade die langsamer bewegten ; Schleifflächenzonen, die also ein geringeres : Arbeitsvermögen als die Zonen mit der hö- i,"zones of the grinding wheel that are uneven
Circumferential speed have form because of their cone \, watching the moving slower; Grinding surface zones, which therefore have a lower work capacity than the zones with the

heren Umfangsgeschwindigkeit haben, die ' Körnerspitze an der Stelle zu - bearbeiten ; haben, wo das meiste Material wegzunehmen 1 ■ ist, nämlich an ihrer Basis, und umgekehrt die j Zonen der Schleifscheibe mit hohem Arbeits- j vermögen die schwächsten Stellen der Spitze.have higher peripheral speed to machine the 'center point at the point ; where most of the material has to be removed, namely at its base, and vice versa, the j zones of the grinding wheel with high working capacity j are the weakest points of the tip.

Dadurch wird der Schleifvorgang verlang- < samt und eine unverhältnismäßig schnelle und j ungleiche Abnutzung der Schleifscheife her- ; beigeführt. ■ 'Thus, the grinding operation is verlang- <together and forth a disproportionately fast and j uneven wear Schleifscheife; added. ■ '

Durch die neue Einrichtung soll dieser
Mangel vermieden werden.With the new facility this
Defects can be avoided.

Sie ist in der Zeichnung dargestellt. Die ■ Schleifscheibenwelle c ist an der Scheibe a ' schräg gelagert und rechtwinklig zum ; Schleif winkel. Das Schleifrad b bearbeitet \ daher, die Spitze mit seiner ebenen Stirn- j fläche tu. . \ It is shown in the drawing. The ■ grinding wheel shaft c is mounted obliquely on the wheel a ' and at right angles to the ; Grinding angle. The grinding wheel \ b edited, therefore, the top with its flat frontal surface j tu. . \

Wie aus der Zeichnung leicht ersichtlich ist, 'liegen nun die Verhältnisse für den Schleifvorgang umgekehrt. Die Zonen der Schleifscheibe mit großer Umfangsgeschwindigkeit bearbeiten die 'dicken Partien der Körnerspitze und die Zonen mit niedrigerer Umfangsgeschwindigkeit die dünnen Partien der Spitze. Hierdurch wird erreicht, daß der Schleif Vorgang rascher vonstatten geht und die Abnutzung der Schleifscheibe, gleichmäßiger erfolgt. Das Abrichten derselben braucht daher seltener zu geschehen und gestaltet sich einfacher als das Nacharbeiten einer konischen Schleifscheibe.As can be easily seen from the drawing, the conditions for the grinding process are now in place vice versa. The zones of the grinding wheel with high peripheral speed process the 'thick parts of the grain tip and the zones with lower peripheral speed are the thin parts of the Top. This ensures that the grinding process takes place more quickly and the wear of the grinding wheel occurs more evenly. The dressing of the same therefore needs to be done less often and is easier than reworking a conical grinding wheel.

Auch bei dieser Vorrichtung kann zur Erzielung genügend hoher Umdrehungszahlen ein Übersetzungsgetriebe zwischen dem An- ' triebszahnrade e und dem Rietzel d' eingeschaltet werden.With this device, too, a transmission gear can be switched on between the drive gear e and the belt d ' in order to achieve a sufficiently high number of revolutions.
