Setting wiper die

Just as the setting of the mandrel is important for successful bending, so is the setting of the wiper die, the basic steps for correct setting of the wiper die:

1. Fix the tube into the jaws of the clamp die and the pressure die.
2. Make sure that the tube is really gripped in the clamp and die.
3. Gently position the wiper die, so that the tip touches the clamp die and the tube (do not use unnecessary force)..
4. Position the base of the wiper die about 1 degree from the tube.
5. Move the wiper die to the holder. Check the position of the wiper die and check that machine is moving freely, especially during large angle bends.

Release the tube, measure the distance between the end and the axis of the Clamp die and compare with the table of recommended distances (You will receive the table with the wiper die) The actual measurement can differ from the value on the table, but this shouldn't affect the quality of the bend.

Just as with the mandrel this setting is only basic and it is necessary to fine-tune it, until the optical check of the bend. Never set the end of the wiper die at the axis of the clamp die = broken wiper die.
