5-4
- The pusher will remain in its home position except for the loading of the new material into the
spindle.
- When the number of clamping device openings of the lathe equal Parameter No. 83 in continuous
cycle, the length of one part which is entered into Parameter "Input overall part length" is deducted
from the overall material length as was determined when the material was initially loaded or
calculated after a restart. This process continues until the barfeed has determined that not enough
material remains to make another part. At this point the End of Bar signal is output to the lathe
- If the lathe is removed from automatic cycle and the clamping device opened the barfeed will drop
out of automatic cycle. When the barfeed is restarted in automatic cycle the pusher will advance to
locate the back end of the material. Once the material is located the remaining length of the bar
stock is recalculated.
- The material is loaded to its pre-load position and will remain there until: clamping device is open,
output from lathe to barfeed confirming the headstock is in its home position and a M-Code output
from lathe to barfeed confirming its is safe to load the new material into the spindle.
Parameters enabled: 3=2, 6=2, 8A=3, 19=2, 25=2, 26=2, 28=2, and 83=1 (all other
"Application" type parameters set to =1)
7. ONE-SHOT SHAFT LOADING (High Speed Loading)
- This parameter is not visible by default, a password is required to unlock. Contact LNS America,
Inc. for more information.
- A pull-to-close type clamping system is required by this application for positioning accuracy. If a
push-to-close type system is used the turret must be used for positioning.
- Each piece of material is equal to one complete part
- NO pusher is to be installed on the barfeed.
- The headstock of the lathe can be either none sliding or sliding type (see point below for sliding
type).
- The loading flag must be configured to a specific length as to position the material to its desired
position inside the clamping device of the lathe ("Top-Cut Position").
- Parameter No. 69 "Loading flag position" must equal the physical length of the modified loading
flag.
- The material is loaded to its pre-load position and will remain there until: clamping device is open
and a M-Code output from lathe to barfeed confirming its is safe to load the new material into the
spindle.
- If using a sliding type headstock lathe parameter 26 "Headstock home confirmation signal
connected to PLC input A7" must be set to 2. For more information on how to do this please
contact LNS America, Inc.
8. CUSTOM
- Password required
- Allows the user to select any combination of parameters to accommodate special applications.
