SIRIO ZIEH ÖL STATION

CONTROL SYSTEM
.. SIEMENS 1513F-1 PN

1. General Description
The drawing oil preparation unit is designed for the optimal pre-treatment of raw, undrawn tubes prior to the drawing process. A large-volume drawing oil bath ensures homogeneous wetting of the tube surfaces. This guarantees uniform lubrication, reduces friction during drawing, improves tube surface quality, and extends tool life.

A consistent material flow as well as stable bath temperature and quality make the system an essential process step for efficient tube production.
