Proper adjustment of the Anti-Vibration Device (AVD) and Movable Anti-Vibration Device
(MAVD) is important for proper machine operation. Proper adjustment will help support the bar
and possibly reduce vibrations during production.
Warning lathe and bar feeder must be in a manual mode during the
adjustment of the Anti-Vibration Device/Movable. Only operators properly
trained should adjust the AVD/MAVD.
Warning proper improper adjustment of the AVD/MAVD may cause
Follow the steps below to adjust material to the AVD/MAVD
Caution when loading a bar for the first time make sure the Movable
Anti-Vibration Device rollers are open. Roller damage may occur when
material or pusher is moved into the rollers.
The AVD/MAVD is normally adjusted at the same time. Follow the adjustment process for both
devices. Note- If the devices open when the bar feeder hood is open the hood switch will be
need to be deactivated for the duration of the adjustment process. Once adjustment has been
completed reactivating the hood switch is required.
1. Load a bar using the bar feeder into the lathe and close lathe collet.
2. Open the bar feeder hood
3. Loosen nut (A) and back screw (B) off counterclockwise until no tension is felt on the
screw. Rollers will be open from material centerline.
4. Press the Pre-Auto button , both Anti-vibration devices will close.
