Summary

[edit]
Description
Deutsch: Kupferfolien-Schneidemaschine der Firma Neumann, Berlin. Speziell entwickelt für das Direct-Metal-Mastering-Verfahren (DMM) der Firma TELDEC zum Herstellen der Press-Matrizen von Vinyl-Schallplatten. Das Glas unten rechts neben dem Gerät enthält den Span, der beim Schneiden des gezeigten Kupfer-Masters anfiel (ein einzelner, ungebrochener Span! DIE besondere technische Herausforderung beim DMM-Schneideverfahren). Eigenes Foto eines Gerätes im TELDEC-Museum, Nortorf.

English: An early disc cutting lathe, probably and AM131 made by Neumann, Berlin in the early 1930s, shown here with a DMM master disc. TheDirect Metal Mastering process (DMM) was developed by TELDEC for manufacturing the master disc of vinyl records. The glass at the bottom right of this photo contains the chip or "swarf", which was cut off during the cutting process of copper masters (normally unbroken, finally with the complete length of the cut groove- the particular challenge of this special dmm-process). Own photograph of a device in the TelDec Museum, Nortorf.
(Note: TelDec is a joint company of Telefunken and Decca founded in 1950)

Español: Uno de los primeros tornos de corte de discos, probablemente el modelo AM131 fabricado por Neumann, en Berlin al principio de los años 1930s, mostrado aquí con un disco maestro del tipo DMM.

El envase de vidrio al fondo a la derecha de esta fotografía contiene virutas que se originaban en el proceso de corte del disco maestro recubierto de cobre.
