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.
