The rotation directions on benders can be confusing.  Many bender controls use the opposite directions from others.  Here are few guidelines to help understand rotation directions:


# Regardless of which way a bender bends (left or right), the direction of the negative and positive rotations stay the same when the controls are the same type.  A control that changes direction based on bend-hand does not follow the standard approach (nor is it the most logical - See Note 1 below).  So the "hand" shouldn't matter.<br><br>
# The direction of rotation can be safely indicated with a CW or CCW direction of rotation from a common viewpoint relative to the bender.  The most common viewpoint is from standing in front of the bender and looking into the collet.<br><br>
# If a bender rotates (+) positive in the CCW direction, then it uses the industry standard and the CNC Bender software standard.<br><br>

CNC Bender Software can be setup with POSITIVE rotating either CW or CCW.  However, by default, all CNC Benders leave SMT setup with CCW the positive direction.


Note 1: It isn't logical because the bend programs written on either hand bender would then be incompatible with the opposite handed bender.
