Most manufacturing and construction industries make large use of metal sheets. To make the sheets be of value or suitable for their different functions, fabrication in necessary. Through sheet metal fabrication, the sheets of metal can be curved to any shape to make them suitable raw materials for the different industries. The process is complex involving different techniques and tools. The businesses involved in offering these services are known as fabrication shops or fabs shops. They use highly trained staff to ensure quality results to their clients. The sheet metal fabrication involves three main processes which are cutting, bending and assembling.
Cutting and burning the metal sheets
For the metal sheets to be used as raw materials, they need to be cut into different sizes. Mostly, the material is cut by shearing. Common tools for cutting the metal are band saws and chop saws. The band saws have special designed hardened blades that feed through the sheet metal to ensure even cutting. On the other hand chop saws which are similar to miter saws are equipped with an abrasive disk that cuts into the metal. In sheet metal fabrication, cutting torches are also used. They have the ability to cut through large sections of sheet metal with very little effort.
Plasma, burn tables, laser cutting tables and water jet cutters are also used. The sheet of metal is placed on a table and the parts are cut out as planned. Such support tables are made of replaceable grid bars. Other hi-tech and very costly burn tables are equipped with a CNC punch capability, a carousel of varying punches and taps. Sheet metal fabrication done by plasma and laser cutting tables introduces robots that are responsible for moving the cutting head in three different dimensions around the material being cut.
