The Bandsaw machine; No more Quality losses

It used for cutting metal, wood or even meat in food processing. It is made up of a continuous band of metal with cutting teeth similar to a wood work saw. The construction of the saw blade is such that it can with stand the rigors of cutting material and bending of the blade while in motion.

It has been developed in two main types of designs which are horizontal and the vertical types. In the horizontal types the work piece is held stationery while saw blade swings through the cut. These systems are best for very long work pieces such as pipes and bars. In the vertical types the path of the cutting blade is stationery while the work piece moves along this path. This type is good for cutting complex angle and lines on the work piece.

Operation of the bandsaw machine

The metal band which has the cutting teeth is powered by the bandsaw wheels which are in turn rotated by a powerful induction motor. Where the tool is used for cutting metal, they are equipped with brushes which remove off metal chippings which could clog the saw. Specialized metal cutting saws are also equipped with a liquid cooling system which sprays a jet of liquid at the point of contact between the band and the work piece. This fluid is re circulated by a pumping system.

Role of the bandsaw machine in industry

It has greatly contributed to the tools industry in metal and wood working. Manual cutting of metal is not possible in heavy engineering works therefore making the bandsaw machines critical in metal working.

Various types of the bandsaw machine

  • Swing type automatic; this is a horizontal type where the head is supported by bearings and the blade is guided by rollers. The blade moves in an oscillating motion generated by a hydraulic cylinder.
  • Automatic double column machines .they have a horizontal saw head with up down movement controlled by a hydraulic cylinder. They are fully automated and deliver more output.
  • Vertical bandsaw machines ; whereby the material being cut moves over the rotating bandsaw and is commonly used in cutting wood which has much less friction.
  • The pipe and neck cutting; generally used for quick cutting of cylindrical shapes.
  • Swing type manual; generally used for high speed cutting and have longer blade life.

Conclusion

The bandsaw is a tool used for metal cutting as well as wood cutting. It works by rotating a toothed band of metal at a high speed over the work piece thus cutting it to the required shape and sizes.

There are two main designs of these equipments are available which are the vertical and the horizontal types. The horizontal types hold the work piece firmly on a vice while the saw moves over it cutting to the required dimensions.

In vertical types, the saw rotates in a single path while the work piece is moves. This type is commonly used in wood working machine where friction is much lesser.

This machine has highly contributed to the metal working industry and is critical in a workshop.

Applications of a Horizontal Bandsaw Machine

Horizontal Bandsaw MachineA machine that is used for cutting wood, metal, plastic and a variety of materials into straight, curved or irregular shapes is called a horizontal bandsaw. A wide range of bandsaw equipments are available in the market. They are made from cast iron, steel or aluminum alloy.

The blade consists of a continuous band of metal which has teeth on one edge. These teeth are used to cut different pieces of work. The blade of the machine is held either by guide blocks or bearings. The saw blade is secured between two wheels or pulleys. One of the wheels called the driven wheel is fixed in place and it provides the power to the saw. The other wheel is the idler wheel which is used to make the blade in the saw tight or loose.

A horizontal bandsaw machine is a versatile power tool and a foundational tool in many workshops. The work piece is clamped in place and then the blade slides down through the work piece and cuts it. A sprayer and a pump keep the work piece covered in a cutting fluid so the metal does not overhead and it can be cut easily.

These are usually used for cutting the supply down to size. The exact finishing cuts are made on more precise equipment. Perfect cuts save a lot of time and stock removal cutting is made much faster. The horizontal bandsaw device is normally used to cut large pieces of work, wood or metal, and different blades make different cuts. They have higher cutting speed and better accuracy. These are very suitable for cutting long bars into different shapes.

Designed for smooth and vibration free functioning, the economical and low noise tools offer maximum output and minimum wastage. The horizontal bandsaw machines are extensively used in automobile, electronic, electrical, wood working etc.

Different types of blades are used for different materials. A diamond blade is used to cut glass, a segmented cold saw blade is used to cut structural tube, and a fabrication blade is used for aluminum, brass or copper. To cut steel tubes, angel cuts and decking, friction & hot saw blades are used. Ferrous applications, cutting extrusions, thin wall tubing, bar stock, angel iron and flat bars are cut with solid high speed steel saw blades. Circular knives are used to cut rubber, fiber glass and aluminum. Carbide tipped saw blades are used to cut aluminum, brass, copper and bronze.

Sparks fly during cutting so protect your eyes and face by wearing a facial safety guard orDouble Column Bandsaw Machine safety goggles. As soon as cutting work is over remove the blade from the saw and store it in a place where it will not get damaged or scratched.

Thus, while selecting a horizontal bandsaw machine, choose unit which gives superior accuracy and which is suitable for cutting long bars in different shapes. The model chosen must suite your requirements. These machines have really simplified and secured the production work, and has also allowed advanced productions at minimum energy consumption rates..
