What is stainless steel slitting?
What is stainless steel slitting?
Steel coil slitting is a method of cutting metal, where large sheet metal rolls or coils are cut with very sharp rotary blades. They are cut length-wise into the large coil to obtain straight lines, creating narrower strips. Circular blades are used as the coil runs through the slitter to make the cuts.
What are Slit coils used for?
Slit coil is used for a variety of end products. Some of the more common include: HVAC duct, lighting fixtures, architectural trim, roof drain pipes, and many more.
What is slitting in sheet metal?
Slitting is a sheet metal cutting process with circular knives, which is used to split wide coiled sheet metal into narrower widths or for edge trimming of rolled sheet. A slitting line consists of an uncoiler, a slitter and a recoiler. The uncoiler, slitter and recoiler are driven by separate motors.
How do you calculate coil length from inner diameter outer diameter and thickness?
To obtain the coil length we have to divide the result by the section of the coil determined by coil width and thickness. The coefficient 1000 is used to compensate the dimensions in [mm] with the length in [m]. For example, a coil with OD = 1600mm, ID = 508mm and T = 0,6mm results in a length of 3010 meters.
What is the difference between shearing and slitting?
Slitting is also a shearing process, but rather than making cuts at the end of a workpiece like shearing, slitting us used to cut a wide coil of metal into a number of narrower coils as the main coil is moved through the slitter.
What is a slitting blade?
Slitter knives have a design meant to slit a wide range of materials in various applications. They find use in many industries because of their ability to cut materials such as paper, plastic and textiles. Most slitter blades feature a beveled edge for optimal cutting power.
How do you calculate coil length?
To calculate spring wire length per coil, you must subtract the wire diameter from the outer diameter in order to get mean diameter. Once you have calculated mean diameter, multiply it by pi (3.14); this will give you the length of wire per coil.
What is crush cut?
Crush cutting knives are blades that cut through a material using pure force. When they only partially penetrate the material, rather than cutting completely through, they are called score cut knives. They work by combining a knife in a pneumatic blade holder with a hardened anvil roll.
What is a shear cutter?
Shear cutting is the separation of workpieces by two blades moving in opposite directions past each other (DIN 8588 2013). A shear cutting tool consists of at least a punch and a die, also referred to as die plate.
How do I choose a slitting saw?
The typical size is 3-4 inches in diameter. There are both larger and smaller saws. The larger the saw, the more runout and wobbling it will have, so use the smallest diameter that will work for your application. Standard Tooth Slitting Saws tend to be thinner and with more teeth than the coarse version.
