CHAPTER 3: SETTING INTO OPERATION 3-5
ALPHA 538/552
2. MOUNTING
The ALPHA 538/552 bar feeder is delivered completely assembled. Because of this, it is possible to
proceed directly to its alignment when in place behind the lathe.
2.1. Alignment
Before proceeding with the alignment of the bar feeder, ensure that the lathe is stable
and preferably levelled.
During the alignment, ensure that there is no reduction unit in the spindle (spindle
liner).
The alignment may be carried out using a nylon string, an optical tool, etc. If you do not have any
alignment tools, please contact LNS or their local representative so they may take care of the bar feeder
installation.
· On each foot, loosen the lock nuts (A) of the leveling screws (B). Then, make sure that the weight of
the bar feeder is evenly distributed over the 12 support points.
· Loosen the nuts and locking screw (D) and make sure that the central screws (C) of the front and rear
feet are supported.
· Open the guiding channel and place the level crosswise on
the lower part. Adjusting the screws (B), set the lateral level
of the bar feeder.
· Adjusting the central screws (C), set the height of the bar
feeder. Normally, when the reference point is known, this
adjustment is done at the factory.
· Together with the vertical alignment, proceed with the lateral
alignment, by shifting the apparatus. If you don't have the
needed material to perform this operation, please contact
LNS SA or your local representative.
· When the alignment is satisfactory, tighten all locking
screws (D). Check the alignment and, if necessary, correct it
with the screws (B).
The lock nuts of the leveling screws should only be tightened after the bar feeder is
anchored to the ground.
