3.3.2 Alignment
Important: Before proceeding with the alignment of the bar feed system,
ensure that the lathe is stable and preferably leveled.
The alignment may be carried out using a nylon string, an optical tool or other means. If you do
not have any alignment tools, contact LNS or their local representative. They may have
alignment tools available or recommend a tool or offer the installation by trained personnel.
For precise alignment, use a 1 or 2 mm diameter nylon string which passes through the back of
bar feeder to the lathe chuck. The string must be slightly under tension for precise alignment.
The purpose of this operation is to perfectly align the center of the bar feeder with the centerline
of the lathe spindle.
1. Clamp an alignment bushing into the chuck of the lathe.
2. Install a bushing at the rear of the bar feeder
3. Pull the string from the rear bushing in the bar feeder through the bushing clamped in the
chuck of the lathe.
(Please refer to 3.3.2 for bar feeder leveling)
4. Using an alignment tool (LNS or others) proceed to the alignment of the bar feeder so that
the nylon string is perfectly centered at the back of the lathe spindle and the front of the bar
feeder. Height adjustment are made using the lead screw in each stand,
5. Secure all screws, nuts and other components related to aligning the bar feeder
6. Remove bushings and nylon string
