9 MATERIAL CLASSIFICATION AND CHOICE OF BLADE
Since the aim is to obtain excellent cutting quality, the various parameters such as hardness of the
material, shape and thickness, transverse cutting section of the part to be cut, choice of the type of
cutting blade, cutting speed and control of head descent, must be suitably combined. These specifi-
cations must therefore be harmoniously combined in a single operating condition according to prac-
tical consideration and common sense, so as to achieve an optimum condition that does not require
countless operations to prepare the machine when there are many variations in the job to be per-
formed. The various problems that crop up from time to time will be solved more easily if the op-
erator has a good knowledge of these specifications. We therefore advise you always to choose
original spare blades that guarantee superior quality and performance.
