8. AIR BLAST RING
The air blast ring is mounted over the bar feed system exit which is driven by solenoid valve YV5. It
serves to build an air curtain which creates forceful air pressure on the bar stock surface when the bar
stock pass through it. The pressure functions as a virtual seal which keeps the hydraulic oil inside the air
curtain.
The air blast right blows at 2 situations below:
1. Anytime when the pusher is moving forward either manually or automatically.
2. While the bar feeder is doing FIRST FEED.
