Although the speed of the cold saw is not as fast as that of the friction saw, the result is a clean cut that does not require deburring. Eliminating the deburring step means saving a lot of raw materials. Moreover, since the cutting temperature is extremely low compared to the friction sawing, the material does not require quenching and is therefore not affected by the quenching effect.
High-speed steel (HSS) for the manufacture of cold saw blades and surface treatment techniques used on them are continuously improved, extending blade life and cutting time. Cold saws can be used to produce small diameter carbon steel tubes with a rolling mill running at speeds up to 180m/min. Tungsten carbide inserts (TCT) inserts are used to cut thick gauge materials (over 0.25 inches [6 mm] and high strength alloys). Work on thin-walled tubes. The choice of HSS or TCT on thin-walled tubes depends on factors such as material hardness, production speed and operator skill.
Single cold saw blades are used for tubes and tubes up to 5 inches (127 mm) in diameter. For sizes larger than this size, a dual saw blade system is advantageous in that it uses two blades for rapid cutting. The blades of such systems are smaller than single-blade systems and can be programmed to work simultaneously or alternately. The software performs the necessary calculations to determine the cutting path, maximizes the cutting rate, minimizes overlap and prevents collisions.Cold saw blade. Because there are two types of cold saw blades, HSS or TCT, and because HSS inserts can be reinforced with various coatings, such as titanium nitride (TiN), titanium carbonitride (TiCN) and titanium aluminum nitride (TiAlN), it An experienced saw operator is required to select the optimum blade for the application and determine the sawing speed and feed rate.As the workforce ages and retire, this valuable knowledge will be withdrawn from the workplace. To help knowledgeable workers, the role of software is becoming more and more important in cold saw control. For the flying saw equipment of the tube mill, the cold saw and the software system need to be more user-friendly.
Shenyang Contor's laser flying saw is used without saw blades, with smooth and burr-free tube cutting quality, which greatly saves the customer's production costs.
