Hack Sawing Machines

In the industry, a hacksaw is a fine-toothed saw, which was originally and mainly made for cutting metal materials and products. Similarly, the equivalent saw for cutting wood is usually called bow saw as its name. A powered hacksaw is called hack sawing machine, which is a type of hacksaw that is powered either by its own electric motor or connected to a stationary engine. Most hack sawing machines are stationary machines but some portable models still exist for specific demands.

The hack saw blades
Conventionally, a standard hacksaw blade’s length is about 250 mm to 300 mm. The blades can be as small as 150 mm. In addition, powered hacksaws may use larger blades in a range of sizes, or small machines may use the same hand blades for convenience. Furthermore, the pitch of the teeth can be from fourteen to thirty-two teeth per inch for a hand blade, with as few as three TPI for a large power hacksaw blade. The issue of blade chosen is based on the thickness of the work pieces, that are, the materials to be cut, with a minimum of three teeth in the material.

Types of Hack Sawing Machines

In the industry, a hacksaw is a fine-toothed saw, which was originally and mainly made for cutting metal materials and products. Similarly, the equivalent saw for cutting wood is usually called bow saw.

A powered hacksaw is called hack sawing machine, which is a type of hacksaw that is powered either by its own electric motor or connected to a stationary engine. Most hack sawing machines are stationary machines but some portable models still exist for specific demands.

Hack saw blades

Conventionally, a standard hacksaw blade’s length is about 250 mm to 300 mm. The blades can be as small as 150 mm. In addition, powered hacksaws may use larger blades in a range of sizes, or small machines may use the same hand blades for convenience.

Blade pitches

Furthermore, the pitch of the teeth can be from fourteen to thirty-two teeth per inch for a hand blade, with as few as three TPI for a large power hacksaw blade. The issue of blade chosen is based on the thickness of the work pieces, that are, the materials to be cut, with a minimum of three teeth in the material.

Because hacksaw teeth are so small, they are set in a wave set. Early blades were made of carbon steel, now termed low-alloy blades, and were relatively soft and flexible. They avoided breakage, but also wore out rapidly, causing inconvenience to users. Now, it is not so common except where cost is a particular concern, otherwise, this type is now obsolete. The low alloy blades are still the only type available for the junior hacksaw, which restrains the usefulness of this otherwise popular saw.

Speed matters

As the industry has progressed for many decades, the way people making sawing are different. For several decades now, hacksaw blades have adopted high speed steel for their teeth, giving greatly improved cutting and tooth life. These newly invented blades were first available in the All-hard form which cut accurately but were extremely brittle, which limited their practical use to bench work on a work piece that was firmly clamped in a vice. So the improvement was imperative.

Meanwhile, a softer form of high speed steel blade was also available, which, though wore well and resisted breakage, was less stiff and so less accurate for precise sawing. All these issues are the main concern of the sawing users at that time. Since the 1980s, bi-metal blades have been used to give the advantages of both forms, without risk of breakage and this invention has solved many inconvenient issues.

Solutions

The solution is, a strip of high speed steel along the tooth edge is electron beam welded to a softer spine. As the price of these has dropped to be comparable with the older blades, their utilization is exploitation are now almost universal. The most common blade is the 300 mm length, and hacksaw blades have a hole at each end for mounting them in the saw frame and the 300 mm dimension refers to the center to center distance between these mounting holes.

Comparison with the band saws

A band saw is a powered saw with a long and sharp blades consisting of a continuous band of toothed metal stretched between wheels to cut targeted materials. Band saws are used particularly in metalworking, woodworking, and lumbering, but can also be used to cut a variety of other materials. The advantages of band saw include uniform cutting movement as a result of an evenly distributed tooth loads, and the capability to cut irregular or curved shapes like a jigsaw.

The minimal radius of a curve is determined by the width of the saw band and the curves. Most band saws have two wheels rotating in the same plane, while one of which is powered; besides, some may have three or four to distribute the load so that the machine is with improved even distribution.

The blade of a band saw machine can come in a variety of tooth pitches and size scales, which enables the band saw machines to be with high versatility, and be able to cut a broad variety of raw materials such as wood, metal and plastics.

Powered band saw

Today, almost all band saws nowadays are powered by at least an electric motor while line shaft versions were once common in the market but are now antiques. The idea of the band saw machines dates back to the 19th century, In about 1809, it was the time when William Newberry had received a British patent for the idea, however, band saws remained impractical basically due to the inability to the fact that it was hard to produce accurate and durable cutting blades using the technology back then, because continual flexing of the blades over the wheels will make the material or the joint welding to fail.
