Replacing the holder box
The bit holders, which are arranged on the milling drum In a spiral shape, are welded
so solidly and reliably with the drum that they are torn off extremely rarely and in
extreme situations (for example, forgotten steel rails in the milling surface).
Each bit on one side of the milling drum (the right or left spiral, as seen from the middle
of the drum) has a counterpart bit on the other side that is in the same position, but
shifted by a few centimeters.
Use this bit to determine the specifications:
- height to bit tip
- distance between bit tip and drum edge.
- Smooth the break point.
- Position, attach, align and weld the bit holder.
The process always occurs with an inserted milling bit!
Ensure that you distinguish between the left and the right bit holder.
Observe the required safety measures during dismantling and welding!
The lateral cutters are normally not welded directly to the milling drum body, but rather to
a distance piece welded to the milling drum. The place where the break should occur
lies between the cutter and the distance piece so that the distance piece remaining on
the cylinder serves as a positioning guide for the new weld if a tear does occur.
