The hacksaw in industrial manufacturing

The hacksaw consists of a fixed sawing blade, available in a variety of lengths, which is held in place using tension from the saw's frame. This frame can be moved in a push or pull stroke, used for the removal of material. The fixed-in sawing blade is very slim, leading to the advantage that there is minimal loss of material during the sawing process. An electric hacksaw is mounted on a base made out of cast steel or cast iron, which contains all the driving mechanics. The workpiece is placed on a sawing table, upon which there is a hydraulically or pneumatically controlled hand-operated vise. Usually steel bars are clamped into the vise. A stop unit allows for repetition in the linear dimension.
  • Separation of materials
  • Minimum loss of material due to a slim sawing blade
  • Main areas of application are in the machine and steel construction industries

The actual saw frame is very robust and mounted on one side. It directs the movement of the saw, and when undertaking the opposite movement of the cutting direction, the blade raises slightly. The height of the workpiece feed is adjusted to fit the height of the saw blade, according to the set dimensions of each cutting stroke. The height of the workpiece is limited to the height of the frame. Almost all types of materials can be sawn using a hacksaw. For the cutting of steel, a cooling device is used to continually cool the sawing blade and the workpiece.

History and background of the hacksaw

The hand operated hacksaw has a really long history. With the start of industrial manufacturing and the development of the first machine factories, the operation methods of a hacksaw were transformed; it could now be propelled using the transmission of a steam-engine. The electric hacksaw was later introduced and then transformed into a fully automatic piece of equipment.

Areas of application and examples of hacksaws

Hacksaws are used throughout industry for the cutting of materials. They are most commonly used in the machine and steel construction industries, where the necessary materials for production (usually in the form of bars) are cut into the desired length. It is important to choose materials whose dimensions are larger than the desired dimensions of the workpiece. Therefore, the workpiece can be processed into the desired length, and then adjusted during the final stages with precision machines such as lathes or milling machines.
Used hacksaw 01
An example is the sawing of steel for trapezoidal screws. Using a hacksaw, they are cut to the length required for their use in most machines. After the hardening of the workpiece, precision machines are used for the finishing grinding stages of the threads, cutting the threads and processing the surfaces as required.

Suppliers of hacksaws

Several companies have specialised in the manufacturing of hacksaws. Some of the most recommended suppliers include BEHRINGER, KASTO, STANDARD, WMW, MITTWEIDA, SAW and WEISEL
