8.3.2. REPLACEMENT AND MAINTENANCE OF THE FORMING PINS
Remove the tool holder cone.
1. Loosen both collaring head locking screws of the cone by 1 - 2 turns.
2. Hold the collaring head in your hand by the break drum or the shank.
3. Rotate the cone clockwise with the other hand until the forming pin lugs reach the end
of the cone groove.
4. Pull the forming pins out.
5. Insert new forming pins into the holes and put the pin lugs into the groove of the cone.
Rotate the cone counterclockwise to retract the forming pins into the head.
6. Carry out the adjustment of the head as described in chapter “The adjustment of the
head”.
¨NOTE!
¨
If the forming pins are caked with residue material, remove
the material carefully by polishing the pins. Any material caked to the
pins reduces the surface quality and the precision of the collar, which
increases the strain on the head and the pins, thus shortening the tool’s
life expectancy.
