Bandsaws are high-performance equipment for direct and shaped cutting of wood and direct cutting of metals. It is rational to use a band saw machine for wood for furniture production and construction – for quick sawing of bars, boards and especially sheets of wood derivatives of particleboard/fiberboard.

Thin closed steel tape (thickness varies from 0.9 to 5 mm), which the band saw has as a cutting element, allows you to perform very clean straight and curved cuts in large work pieces with a thickness of more than 200 mm.

According to the principle of operation, the band saw is similar to a jigsaw – only a closed, welded in a ring cloth in it does not move reciprocatingly, but in one direction along an endless closed contour on two pulleys, like in a conveyor. This contributes to a large resource of the long plane of the belt web (cutting tape), which, due to the large length, is slowly blunted and rarely needs to be replaced.

The cutting plane is obtained with a small roughness because in many cases, finishing the surface is not required. Another important advantage that any band saw machine has is the absence of chips, very little waste, this is light dust, as with grinding machines. In this, a band saw for wood compares favorably to a circular saw, which has discs thicker than saw blades.

The band saw history

In the first, a patent for the design of band sawing machine for wood processing was obtained in 1807 by the English engineer William Newberry. And only in 1866 the French company Panhard & Levassor created a band saw machine for cutting metal. Two years later, it was installed at the shipyards in Le Havre, and a year before the British tried to cut armor on it for their numerous battleships then built.

In the last third of the 19th century, quite a large number of models of woodworking machines were developed by various European firms, but only five types: Fugger, reysmusovye, milling with a vertical spindle, vertical drilling and band sawing machines.

The main disadvantages of all types of machine tools on https://www.luxuryhomestuff.com/woodworking-tools/ were that during this period of time, drives were used that operated due to high vapor pressure or water wheel rotation. Moreover, they were used only at fairly large enterprises and rotated the main shaft that passed through the entire workshop, from which power was supplied to individual machines by means of a belt drive.

The first band saw machine with an individual electric drive appeared only in 1911. Today, its analogs are used not only in woodworking, but also in lumbering, when cutting metal, plastic, leather, textiles, stone, and even frozen meat and fish briquettes. These are table sawing machines, horizontal and vertical for longitudinal cutting of logs, including dual (tandem), designed for cutting out non-rectangular blanks, machines for edge cutting slabs and boards, etc.

Definition band saw machine.

The band saw is a machine, the working body of which is a saw in the form of a closed tape, stretched over pulleys and continuously turning around them. The location of this saw machines is divided into horizontal and vertical.

In accordance with the national classification that was once in force, vertical woodworking machines with a cutting height of up to 80 mm belong to carpentry band sawing. They are designed for straight and curved sawing boards, shields and sheet materials on the workpiece.

Used in sawmills, woodworking and furniture enterprises for rough cutting, as well as for a variety of carpentry work that does not require special precision. read more
