A Closer Look at the Bandsaw


By westyorkssteel | 5th December, 2017

West Yorkshire Steel are happy to offer a number of different steel processing services – the options that we have mean that we can deliver a range of different products to our customers just as they need them! We decided, however, that it would be good to look into some of the toys that we have on site that help us to cut and shape our steel, starting with the bandsaw.

If you’re not sure what a bandsaw is, then imagine an extremely long saw blade and join the two ends together to make a loop. The looped blade is then mounted vertically between two wheels that controls the speed the blade travels at, and the cutting edge is one of the vertical edges, where the blade runs straight from top to bottom.

The major benefit of the bandsaw is that the cutting edge only runs in one direction, meaning that neither the blade or the material being cut has to cope with stresses and strains in different or competing directions, like a circular cutting blade would give. Depending on the length of the blade, it can also limit the amount of heat built up through friction as the blade’s travel time allows it the temperature to remain more steady.

The bandsaw has actually existed since the very early part of the 19th Century, patented by William Newberry in 1808. It was technically very advanced, but nothing really happened with it for a number of years, probably because of the difficulty of making saw blades robust enough or repairing blades when they broke. Around 50 years later, a patent to improve bandsaw blades and operations saw them gain some ground with tradespeople and around 1880 a foot-powered version (that worked in the same way as a sewing machine) improved the size, weight and power of bandsaws when compared to the large water-powered versions that went before.

Although chiefly a woodworking tool, technological developments have allowed blades to be made stronger, more reliable and more resilient to the pressures that cutting causes. Today, we can tailor equipment to perform any number of jobs, including allowing bandsaws to cut any number of metals – which is great news for our customers!

West Yorkshire Steel supply rectangular cut block and plate as cold sawn, meaning that it can be supplied close to your required finished dimensions, while round bar can be cold sawn up to 1000mm in diameter – and as always, we can supply nationwide across the UK!
