Advantages of cutting devices:•simple change of cutting dies
•mechanical specimen rejectingsystem (reducing the risk to get
injured by the sharp cutting
edges)•possibility to sharpen the cuttingdie several times•cutting die and rejector are twomodular parts so that the cutting
die is available as spare part for
later changement
