Steady Rest Unclamp (ISNC M39)
After the spindle is stopped, M39 unclamps the optional Steady Rest device during
automatic cycle operation. The spindle MUST BE stopped when this M-Code executes or
an error will appear and the cycle will be halted.
The Steady Rest device can be manually hitched to the Z-Axis to assist with movement of
the Steady Rest to the proper location. The position of the Steady Rest device is tracked
in order to avoid colliding with the tailstock.
A safety switch located on a bracket under the way cover also protects against the Steady
Rest and Tailstock colliding. If the safety switch is tripped, the machine will enter the
Emergency Stop mode.
This optional device is used with turning centers to hold long pieces of stock in the center
while cutting.
Spindle Gear 1 (ISNC M41)
M41 sets the spindle to Gear 1, or the low gear range.
Low Gear Speed Range for TM18:
Minimum RPM = 5
Maximum RPM = 600
Spindle Gear 2 (ISNC M42)
M42 sets the spindle to Gear 2, or the high gear range.
High Gear Speed Range for TM18:
Minimum RPM = 15
Maximum RPM = 1600
The spindle must be stopped prior to executing the M39 Steady Rest
Unclamp.
The position of the Steady Rest can only be tracked when moving the
Steady Rest with the Z-Axis. If the Steady Rest is moved manually
without the use of the Z-Axis, then the control will not be aware of
this new position for the Steady Rest which will either allow the
tailstock to possibly collide with it or improperly limit the motion of
the Z-Axis when hitched to the Tailstock.
