Cold Saw Machines

Cold Saw Machines
A cold saw is a sawing machine that uses a circular saw blade to cut metal. The name "cold saw" comes from the cutting process they employ. These sawing machines transfer the heat generated by cutting to the chips created by the saw blade. Therefore, the blade and material being cut remain cold. Cold saws use either a solid high speed steel (HSS) or tungsten carbide-tipped, resharpenable circular saw blade. They are equipped with an electric motor and a gear reduction unit to reduce the saw blade's rotational speed while maintaining constant torque. This allows the HSS saw blade to feed at a constant rate with a very high chip load per tooth. A cold saw cut produces minimal burr, no sparks, no discoloration and no dust. The material being cut must be mechanically clamped to prevent movement during the cutting process. Extra care should be taken to choose the appropriate number of teeth, saw blade type, cutting speed and feed rate. All of these variables are based on the type and size of material being cut. Cold saws are capable of machining most ferrous and non-ferrous alloys. Cold saws are intended to be used with a flood coolant system to keep the saw blade teeth cooled and lubricated.
