Used Hacksaws for Sale — 69

The conventional hacksaw is used for wood- and metalworking. Today, the further developed machine-powered hacksaws are used in various branches of industry. The industrial hacksaw can pretty much saw all materials.

What characterises the hacksaw?

This type of saw has specific characteristics, like the U-shaped clamp, which is open on the bottom. A saw blade, which is fixed in between the ends of the clamp, cuts the various materials using lifting and pushing movements.

The hack saw has been developed over 4,700 years. Materials have been cut by hacksaws for a millennium. Relics and debris from the Bronze Age provide evidence to show that this type of sawing process was used by the ancient Egyptians. The power hacksaw was developed in the industrial revolution and through the introduction of the steam engine. The rapid growth of industrial production led to the development of the electric hacksaw, which now been transformed into a fully automatic machine.

What advantages does the hacksaw have and where is it used?

The function of a hacksaw is very simple and has a variety of advantages. The saw blade, which is fixed between the joints, is very taut due to the tension. Therefore, there is no chance of it bending. Additional, incredibly narrow saw blades can be used, which ensure a minimal loss in the workpiece’s material, and allows for minimal cutting processes to be undertaken. Due to stability, the clamp is thicker than the hack saw and it restricts the workpiece due to its height and width.

When using a hand hack saw or junior hack saw, the lifting movement is always an idle stroke. This means that only half of the work is actually productive. Materials that are difficult to cut can be processed using a broaching process, which is where only a few saw teeth are required. The hand operated hacksaw is mainly used in the wood and metal industry. Common types of saws used in woodworking are the jig saw, branch saw and frame saw. The hand-held hacksaw is a common tool used for metalworking. The lifting and pushing movements of the power hack saw is powered using a motor and a gear hub, which transforms the rotation movement. The base frame, made out of grey cast iron or cast steel contains all of the mechanical components. The workpiece can be clamped onto the saw table using a hand operated, pneumatic or hydraulic vice. A stop is used to ensure a high level of accuracy in repeated length measurements. The machine’s saw clamp is loaded on the side and guides the sawing and lifting movement of the saw blade; the lifting movement occur in the opposite direction of the cutting movement. Almost all materials can be cut using a hacksaw, and power hack saws are often used to saw steel bars. When sawing metal, a pipe or other construction for the supply of cooling agent, is available to ensure that the workpiece and saw blade remain cool.

The hacking saw is mainly used in machine and steel construction, for cutting workpieces into the required length. A common method is to choose dimensions that are somewhat bigger than the dimensions of the finished workpiece. This allows for the work piece to be cut into the desired length during finishing touches using a lathe or milling machine. One example is cutting tool steel for trapezoidal screws, which are used in many different machine tools.

Who discovered the potential of the hacksaw and established themselves as a manufacturer of hacksaws?

There is an enormous demand for industrial hacksaws in the big industry branches of machine and steel construction. Those who have specialised themselves in producing hacksaws include MITTWEIDA, KASTO, BEHRINGER, STANDARD, SAW, WMW, and WEISEL. The hacksaw has continued to be developed since the time of the ancient Egyptians in order to be optimised to suit all kinds of materials and current scientific knowledge.
