That is there would be approx 66 square to cut out of 4m.The end result would look like someone with every second tooth missing.
It is essential that there be little or no dross as the finished bar has to fit into a slotted jig which is 3mm wide.
If there is too much dross we would need to clear it up. The time taken to do this would seriously impact on the cost, as we would be cutting 100’s meters.
Cost has to be considered, main issue is having the least possible dross .
Also the mechanised application needs to have an accuracy of +-0.3mm, Is this achievable ?
