Flame-Cutting Machines  Manufacturers, Traders, Suppliers

Flame cutting machines are machines for thermal cutting of workpieces. As a rule, flame cutting machines can cut out contours from sheet metal. However, there are also oxygen lances that can be used to separate concrete, for example. Flame cutting machines are mostly portal machines. An oxy-fuel jet causes thermal distortion of the workpiece to be cut and thus a burr along the cutting edges. With CNC controlled flame cutting, a distinction is made between 3 technologies and methods generally used today. These are oxyfuel flame cutting, plasma flame cutting and laser flame cutting. While heat distortion and burrs can still be detected on the workpiece to be processed during oxy-fuel flame cutting, they decrease with increasingly higher energy density during plasma flame cutting and laser flame cutting. Oxy-fuel cutting machines have 1 to 12 oxy-fuel burners and are suitable for cutting all unalloyed structural steels with a material thickness of 3 to 1,500 millimeters. Plasma cutting machines have 1 to 6 plasma torches and can cut not only unalloyed structural steels but also aluminium and stainless steel. The material thickness that can be cut ranges from 0.5 to 300 millimeters. However, acquisition and operating costs are considerably higher than with the oxy-fuel cutting machine. The laser flame cutting machine has a CO2 laser that is capable of cutting 40 mm thick steel plates, 50 mm thick stainless steel plates and 25 mm thick aluminium plates. Copper and all other metals with good thermal conductivity cannot be separated with the laser flame cutting machine.
