Metals are divided into pieces of various shapes and sizes following how it will be used at the end. Primarily, metal cutting is a process whereby unique tools are used to cut off layers of metal out of a huge workpiece.
The resultant layer should gratify the predefined specification measures like thickness, shape, and dimension.
Metals are commonly tricky and very hard to cut. Metal cutting encompasses numerous procedures and various tools. Since the intrinsic tensile property and resilience of each metal is quite different from each other, each metal needs adequate processes, tools, and devices to cut and get it into their desired shape
Manual Cutting Tools
Manual cutting tools had proven to be one of the best options when cutting or chopping smaller pieces of metals. Manual cutting comprises making use of smaller instruments that can be utilized using the hand.
For instance, manual cutting tends to come in helpful when chipping of cutting smaller portions of metal to produce small holes for rivets, screws, and bolts.
Manual metal cutting tools include;
1. Metal Hacksaw.
Metal hacksaw is very similar in terms of structure to wooden saw except that it is made out of very hard steel to help and assist in cutting through hard metal surfaces. A metal hacksaw seems typical to be an inverted 'U' shape, and it is readied with teeth that run along its exterior end.
Metal, wood, or plastic are overhauled on one end to help and assist by holding the hacksaw in place. Usually, the blade is removed by the help of small pegs that help in compressing or losses the blade as needed.
Hacksaw blade measures around to 10 to 13 inches in terms of length, though you can get smaller, 6-inch models that are used for cutting tinier metals.
The number of teeth present varies across diverse kinds of hacksaws, thou the number falls between 42 and 32 TPI.
TPI means Teeth Per Inch.
Chisels are equipment used for cutting off more and unwanted portions of metals. Mostly, chisels are made use of in the metal cutting industry for chipping or cutting cold and hot cutting procedures. A cold chisel is typically used to cut off waste fractions of metals.
Cold chisels are used for a broad range of cutting task which includes cutting keyholes, thin metal sheets, rivets and squared shaped corners, etc.
Models of cold chisels are usually burnt to produce hard brown and using hard steel and flame-tempering innovation to improve and increase its cutting ability.
Diamond chisels are mostly used to chip outpointed corners and slender grooves in metals, while hot chisels, on the other hand, is used to help cut through the metal. Hot chose heated to make it softer.
Rounded chisels are used to cut notches in metal surfaces. Chisels are fitted to cutting metals that are very soft than themselves.
3. Industrial shears
Industrial shears are made and produced from carbonated steel, and they are used to cut metals like aluminum, steel, and stainless steel.
Metal cutting shears look like a pair of scissors, and they come in different sizes. Massive models of metal shears are used electrically.
Manual cutting tools has proven to be a vital part of the metal cutting process despite the use of automated and advanced machinery in the metal cutting industry.
