There are two different kinds of saws. Band saws are used to cut both easy and hard-to-machine workpieces, such as aluminium, steel, stainless steel and nickel alloys. Other kinds of saws are used mainly for soft materials and are mostly used in construction and roadworks industry. Large machines in particular are used for roadworks, and also by the emergency services. Dividing machines with two-stroke engines used by the emergency services are optionally equipped with a stone or metal blade, and these powerful machines are used for cutting into the metal of crashed vehicles. Usually used in heavy industry and large-scale production operations, stationary machines are housed in large containers, providing protection to employees from offcuts and flying shrapnel.
It is essential that trained staff should clean and maintain the machines, as they need to be handled with care in order to avoid damaging any expensive components. In the stationary units, cooling lubricant is recommended. Equipped with sensors and feeds cutting machines can achieve a high degree of automation. Rippers can be combined with industrial robots
and automated transport systems.
