Cutting metal sheets can be an intimidating task. It is important to know how to cut the sheet correctly in order to get the desired shape and size of your product. Today, most people use computer-controlled machinery or large power shears for this process. Here are two types of precision cutting that you should know about: punching and laser cutting.
Punching and laser cutting are two types of precise cutting:
The two styles of cutting are strike and punch. The die is built up from two intermeshing plates, which are attached opposite each other. A piece of sheet steel is inserted between the plates to form a barrier. The die’s design is engraved into the steel using the punch. Punch cutting is quicker but more difficult to modify for repetitive assembly line processes.
The cutting machine uses a high-intensity beam of light to cut the metal sheet by directing it through an optical fiber to the workpiece, allowing for more accurate cuts and less distortion than laser technology that is used in many car manufacturing plants. The material being cut does not actually catch on fire because only its surface layer melts so there are no harmful fumes.
More accurate and faster than a pneumatic press, laser cutting is a more recent method of cutting sheet metal. A laser heats and cuts the metal using a CNC or Computer Numerical Control machine. The same nozzle that supplies the laser beam also receives oxygen. Because of the oxygen/laser combination, cutting speed is increased over that of traditional cutting methods.
The cut line is very clean and free of burrs because the laser beam can pass through its own smoke. With this technology, fabrication times are reduced to just minutes instead of hours or days that were once required for punch presses or shears. Laser-cutting machines also require less maintenance than other sheet metal cutting equipment since there are no moving parts.
Metal sheets have been used since before the invention of mechanical technology. The metal sheets may be cut and formed using hand tools. Although a hammer and knife, or an axe, can be utilized to chop steel sheets, it is dangerous and should not be attempted. Instead, tin snips are preferable. They’re popular among hobbyists because they’re easy to use.
Tin snips are usually made of forged steel and are generally used for cutting sheet metal up to 18 gauge, or about .040 inches thick. Tin snips consist of two blades that meet along a sharp edge with one handle attached at each end. The handles have knobs so the user can apply considerable pressure in order to cut the metal sheet.
Metal Sheet Cutting Machine:
The first step is to prepare for the workplace. This should be a well-lit, orderly room big enough for you and your machine that no one will get injured or involved in the cutting process. Before beginning any cutting operation, ensure that all safety guards are in place and operational.
The next step is to make sure the sheet metal you are using has not already been punched or drilled. If there’s a hole in it, how will you be able to attach your product once completed? Punching and drilling can be done before cutting begins if necessary. Now you’re ready for the actual act of cutting; this step requires a machine.
Finally, aviation snips, which are used by construction workers and professional sheet metal workers, are a type of sheet metal cutting tool. Unless using upright snips with offset jaws, such as aviation snips, the user of aviation snips must put his/her wrist in an awkward position while grasping the metal to be sliced.
