When it comes to adjusting the speed of plasma cutting machines, we should first understand what factors affect them. The influencing factors are the type of the cutting machine, the material of the cutting workpiece, the input voltage at the cutting site, and the working gas and flow rate. Understanding the factors affecting cutting speed, the next content, we will give you a detailed introduction of the adjustment method.
First of all, we need to understand that different auxiliary cutting gas cutting speed specifications are also different. Taking air plasma arc cutting as an example, when cutting carbon steel plate with 230A cutting current as standard, the cutting speed of 6 mm thick carbon steel plate can reach 3300 mm/min is more suitable; when the thickness of the plate is adjusted to 40 mm, the cutting speed is limited to 500 mm/min to ensure the cutting effect and quality. If other assistants cutting gases are used, such as pure oxygen cutting, the cutting speed decreases more. At the same cutting current of 230A, the cutting speed of 40 mm carbon steel plate is only 350 mm/min, although pure oxygen plasma cutting of 6 mm thick carbon steel plate can be increased to 3700 mm/min. Therefore, to adjust the speed of the plasma cutting machine, we should first control the thickness of auxiliary equipment.
Generally speaking, as a CNC cutting equipment, the staff should improve the cutting speed as much as possible on the premise of ensuring the cutting quality of the plasma cutting machine
. This not only improves productivity but also reduces the deformation of the part being cut and the heat affected area of the slotted area. If the cutting speed is not appropriate, the effect is the opposite, and the sticky slag will increase and the cutting quality will decrease.
