Lubricant/coolant

The lubricating/cooling fluid must ensure that the blade teeth and material in the
area of the cut do not overheat. Furthermore, the quantity and pressure must be
sufficient to remove the swarf from the cutting zone. The fluid must be an
excellent lubricant, such that prevents abrasion of the teeth and welding of the
swarf to the teeth themselves (seizing).

Blade structure

The circular blades most frequently used for cutting---off machines are HSS---
DMo5/M2 consisting of a single piece and characterised by a high level of
toughness and a good cutting resistance. With non---ferrous materials it is normal
to use circular blades with brazed hard metal (HM) cutting edges, which offer
excellent resistance to wear but low resistance to impact, which in any case is not
generally a problem with non---ferrous materials.
They consist in a disk made of alloy steel (71 Cr 1) with teeth and places for the
plates, made of Widia K10.
