What Is a Scroll Saw?

The saw blade is mounted on a sliding seat that can be moved along a sliding guide (or roller), and a sawing machine is realized by a feeding mechanism.

The saw blade is mounted on a sliding seat that can be moved along a sliding guide (or roller), and a sawing machine is realized by a feeding mechanism.

The material of the saw blade is steel and cemented carbide. The hacksaw blade is usually made of spring steel containing 1% Mn and is heat treated for cold and hot sawing of ordinary steel. The sawing process of the hacksaw blade is the saw blade to metal

Transverse cutting of the profile with a high-speed rotating saw blade (the linear speed of the general saw blade is 100 ~ 120m / s up to 140m / s). The end face of the cut profile is straight. Saw cutting is widely used for the cutting of profiled sections, pipes and alloy steels.

The sawing is divided into hot saw and cold saw according to the temperature of the metal being cut. The hot saw has high efficiency and less energy consumption, but the end of the sawed profile is easily bent when cutting. The cold saw is the opposite.

The sawing method can be divided into three types according to the kinematic relationship between the sawed part and the saw: (1) The sawing machine is not moving and the rolling part is fed. The saw operated in this way is called a fixed saw, and its structure is simple, but the cut is easily skewed. It is mostly used for simple small and medium-sized rolled products to be bunched for cutting; (2) The rolling material is not moved, and the saw is fed by the saw. The saws that work in this way include lever saws, slide saws, and four-link saws. The lever-type saw has a simple structure and convenient operation, but has low production efficiency. It is mostly used for sawing small cross-section samples or cutting away scrap parts of rolled materials. The most widely used in rolling mills are slide-type and four-link-type saws, which are characterized by high production efficiency, large strokes, reliable work, and straight cutting end faces; (3) the rolled products are sawed while making longitudinal movements. cut. A saw working in this way is called a flying saw. For example, after installing in a continuous pipe welding machine, the welded pipe in operation is cut into a saw with a fixed length. During the sawing process, the flying saw blade must not only rotate around the saw axis, but also move at the same speed as the steel. It must also cut the steel into different lengths according to requirements, and it should always be perpendicular to the steel axis and ensure that the cut is flat. ^[2]
