Blades
The blades are made of special steel. Each version is available in 5 standard widths. In order to prevent a jamming of the blade in the PCB, the blade should be at least 0.15 mm narrower than the milling slot. Intermediate sizes are manufactured according to customer's specifications.
The L-shaped blade is used if there are small off-cut distances.
Off-cuts right and left of the edge are punched out with the T-shaped blade. A turning of the PCB is not necessary.
