Metals are cut into pieces of different sizes and shapes based on the end use. Metal Cutting is actually a procedure where special tools are used to chip or cut layers of metal out of a bigger workpiece.
The resultant chip or layer should satisfy the predefined specification criteria like shape, dimensions and thickness.
Since metals are often hard and extremely tough to cut through, metal cutting involves multiple processes and different tools. Because the inherent tensile property and strength of each metal differs, each metal requires suitable devices, processes and tools to obtain it into the specified shape.
Manual Cutting Tools
Manual cutting tools conitnue to be the very best choice for cutting smaller pieces of metal. best metalworking tools includes smaller instruments that may be operated using the hand.
Like, manual cutting tools tend ahead in particularly handy when cutting smaller pieces of metal to be able to make small-sized holes for inserting bolts, rivets and screws etc.
This implement is comparable in structure to a wooden saw except that it's constructed out of hardened steel to simply help it cut through tough metal surfaces. A hacksaw typically seems to be an inverted 'U' shape and is equipped with teeth that run along its outer edge.
Wood, plastic or metal are fixed on a single end to simply help hold the hacksaw in place. The blade is normally detachable by way of small pegs that help tighten or loosen the blade as required. Hacksaw blades typically measure about 10 to 12 inches in total although you will find smaller, 6 inch models for cutting smaller metals.
How many metal teeth can also vary across different types of hacksaws although the number falls between 14 to about 32 TPI (Teeth per Inch).
Chisels are useful for chipping off extra or unwanted pieces of metal. Chisels are used in the metal cutting industry for both 'cold' or 'hot' cutting processes. A cold chisel is used to hack off waste items of metal.
Cold chisels are used for a wide variety of metal cutting tasks hat include Suncutting rivets, thin metal sheets, square-shaped corners and keyholes among several others.
Most models if cold chisels are burnt to a tough brown by using strong steel and flame-tempering technology to boost its cutting ability.
Diamond shaped chisels are used to cut fully out sharp corners and narrow grooves in metals while hot chisels (the chisel is heated to produce it softer) can be used to simply help it cut through the metal.
Round headed chisels are used to cut indentations in metal surfaces. Chisels are particularly suitable for chipping metals which are softer than themselves.
Chisels must work in tandem with the proper hammer. An over-sized chisel will have a tendency to absorb the blow from a lighter hammer and will unable to accomplish any useful cutting.
They're specially produced from carbonated steel and can be used to cut through metals such as for example steel, stainless in addition to aluminum.
Metal cutting shears typically resemble a pair of scissors and can be found in varying sizes. They can vary from smaller, portable, manual models to huge, floor-mounted or bench -mounted versions. Bigger types of metal shears are operated pneumatically or electrically.
Despite the use of advanced and automated machinery in the metal cutting industry, manual cutting tools continue to be an integral the main metal cutting manufacturing process.
