Compared with manual and semi-automatic cutting methods, the laser pipe cutting machine can effectively improve the cutting efficiency and cutting quality of the plate, and reduce the labor intensity of the operator. How to identify the quality of laser pipe cutting machine? Some small and medium-sized enterprises even use manual cutting and semi-automatic cutting in some large enterprises. Therefore, consumers must pay special attention to the quality and cutting effect of laser tube cutting when purchasing a laser tube cutting machine. Next, the laser equipment manufacturer will show you how to identify the quality of a laser pipe cutter.
Cutting verticality is also an important index to measure cutting quality. This is related to the degree of secondary processing after the workpiece is cut. It is usually used to represent perpendicularity u or angular tolerances. The verticality of arc cutting is closely related to steel plate thickness and process parameters. Usually, U≤ 1%-4% of the thickness of the steel plate, U≤ 0.5mm for laser cutting.
The cutting width analyzed by laser equipment manufacturers is one of the important characteristic values to evaluate the cutting effect of equipment, and also reflects the minimum circular hole radius that can be cut by laser pipe cutting machines. In general, the width of the incision should be measured by the size of the wide part of the incision. The incision width of ordinary plasma cutting machine is 0.15~6mm
The finish of the cut surface is used to describe the appearance of the cut surface and to determine whether subsequent machining is required after cutting. The standard measurement method is to measure the Ra value at 2/3 of the cutting depth. Due to the cutting airflow, the cutting direction will produce longitudinal cutting ripples.
In general, the surface finish requirements of oxyacetylene cutting are: Level 1 Ra≤ 30m, level 2 Ra≤ 50m, and level 3 Ra≤ 100m.
