Power Saws
For many years the only way to saw off metal was to use a hand saw.The development of power driven machine for driving metal-cutting saw blades has made the task considerably easy. Power saws can do the work more rapidly and with greater accuracy. From the picture can you guess how these cutting machines are working?
Band Saw Machines In this machines a flexible saw blade driven in a continuous loop around two wheels-like a fan belt in a car - the band machine provide a continuous cutting action. Band machines could be used for different materials. Band machines are available in Horizontal models and vertical designs. Shaping slotting and cut-off operations can be performed on both types, in addition to these operations, band saw blade could be replaced with filing or abrasive band so the machine can also do filing, polishing operations. What are the advantages that you think, the band saw machine has over the other types of saw machines?
Disc Machines The cutting action of the disc machines depend or a circular disc cutter, rotating at high speed. It is used mainly for cutting parts off, in metal work and carpentry work.//azadhacksaw.com/images/hacksaw6.jpg

Some of the machines works by rotating a circular disc, which has a sharp edges.
ReplyDeleteSome has a belt of metal, which rotate also in two ways.
both has advantages and disadvantages, and each one has a specific use.
for example, band saws used in cutting trees and meat.
Disc machines used to cut metal، ceramic, and sheets of wood.

In my opinion, I think that the band saw blade is the best, where it is available in vertical and horizontal models. It also can perform Shaping slotting cut-off, filing, polishing operations.
ReplyDeleteI also think that the power hack saw is just like the regular hand hacksaw but uses the machine power to cut faster and is more accurate.
The Disk Machines uses circular motion to cut metal pieces off and are also used by carpentry probably for cutting wood
