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.
- 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.
- If a bender rotates (+) positive in the CCW direction, then it uses the industry standard and the CNC Bender software standard.
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 hand benders (left to right and right to left).
