Definition of band saw cutting machine
Today, cutting using a band saw blade is a special place in the industry. And it has been useful in cutting different materials in different shapes. Cutting in the band saw machine is done by a toothed steel belt. The two ends of this steel strip are welded together and are rotating around two (or more) plates of the device. The material of this belt saw blade is very diverse and depending on its application, it is produced in different ways. The specifications and teeth of this blade are varied and are selected according to the piece or material to be cut.
Types of band saw cutting machines have at least two blades. In some large or special devices, the number of these layers can be more. In the standard and general model of these devices, one plate is connected to the driving force of the device, and the second plate is on the other side of the device and is random. The band saw blade belt is installed around these two pieces. And with the movement of the first layer, a rotational movement is created in it. Depending on the type of machine, the piece to be cut is placed in the machine between the slices. With the movement of the saw blade, the cutting process takes place.
The driving forces of cutting machines have been in various types. In the old days, a steam engine or a diesel engine was used to move the saw blade. But today, mainly the power of the electric motor (electromotor) is the most important driving force of these devices.
Applications of band saw cutting machine
Band saw cutting machines are used to cut different types of materials. The scope of this application is so large that every day a new device and blade is introduced to the industry. In the following, we can mention the cases for which the band saw cutting machine is one of the preferred choices today:
Cutting all kinds of metals (such as iron, steel, steel, cast iron, aluminum, copper, brass, bronze, super alloy, etc.)
Cutting all kinds of meat food (such as fresh meat, frozen meat, fresh fish, frozen fish, chicken, bone, pen, etc.)
Cutting all kinds of food (such as bread, cake, sugar, vegetables, fruit, etc.)
Cutting all kinds of wood materials (such as soft wood, hardwood, fresh wood, dry wood, tree trunks, logs, sawdust, beech, alder, coal, etc.)
Cutting all kinds of cellulosic materials (such as paper, cardboard, cardboard, filter, tissue, etc.)
Cutting all kinds of polymer materials (such as rubber, plastic, glue, synthetic leather, polyca, composite, PVC, nylon, etc.)
Cutting all kinds of textile materials (such as fabric, yarn, denim, carpet, leather, etc.)
Cutting all kinds of artificial materials (such as cloud, foam, sponge, etc.)
Cutting all kinds of building materials (brick, stone, light concrete, gypsum block, asbestos, etc.)
The band saw blade and the band saw machine used to cut each of the aforementioned various materials (in different physical dimensions and geometric sections) are specially designed and manufactured. The high efficiency of these machines, as well as the unique capabilities of these devices and the blades used in them for various purposes, have turned band saw cutting technology into one of the most efficient and important equipment needed by industries, so that every workshop or a factory needs to use one of these types of these machines.
History of band saw cutting machine
The band saw idea dates back to at least 1809, when William Newberry received a British patent for the idea. At that time, it was not possible to produce an accurate and stable band saw blade, and most practical and industrial efforts always fail. The flexibility of the blades when moving on the flakes, along with the butt welding of the blades, was one of the most important factors that caused the failure of the tests.
Nearly forty years passed until a French lady named Anne Paulin Crepin invented a welding method to overcome these obstacles. He patented his innovative method in 1846 and immediately assigned the right to use it to the Perin factory in Paris. The combination of this method with new steel alloys and advanced tempering and heat treatment techniques allowed Perrin to produce the first modern band saw machine of those days.
