.. SIEMENS 15 13F-1 PN


1. General Description
The draw-oil preparation system is designed for the optimal treatment of un-drawn tubes prior to the drawing process. A large-volume draw-oil bath ensures homogeneous wetting of the tube surface, providing uniform lubrication, reducing friction during drawing, improving the tube surface quality, and increasing tool lifetime.
A constant material flow as well as stable bath temperature and bath quality make this system a critical process step in efficient tube production.
