How it works

Equipment description

In the finishing stage the threading machine performs precision shaping of the aluminium tube blanks. The main procedures are thread rolling on the tube mouth, facing the tube ends, trimming excess material at the tube tail with an additional 45° adjustable chamfering tool, and polishing the tube shoulders.

Where it sits in the line
