Characteristics Of CNC Plasma Cutting Machine And Factors Affecting Cutting Accuracy

In the metal processing industry, CNC plasma cutting machine processing technology is often used, and the quality of the finished product is related to many factors. Today, CNC plasma cutting machine manufacturers will briefly introduce the characteristics and characteristics of CNC plasma cutting machines. , and some factors that affect the cutting accuracy, I hope to bring you some help.
About features:
1. Fine. CNC plasma processing penetrates the material with fine slits, the workpiece is cut according to the design procedure, with high dimensional accuracy, and can cut acute angles and narrow slits.
2. Flat. The incision has no burrs, good verticality, no deformation of the seam edge, no heat-affected zone, and the bright cutting edge can be directly welded to form.
3. Fast. The focused laser beam has a small spot and high power density, like a sharp knife, with fast cutting speed.
About processing objects:
1. Except for gold, silver and copper with high light reflectivity, most materials can be cut by laser, which is more suitable for carbon steel and stainless steel.
2. Various types of machinery manufacturing sheet metal parts for medium and small batch blanking processing.
3. It is an ideal choice to use laser cutting for new product prototypes that are not economically economical or time-consuming to open molds.
4. Workpieces with complex shapes and multiple varieties.
5. Materials and workpieces that cannot be processed by conventional cutting methods or do not meet the quality requirements.
6. Work, weight, cutting tools and various metal and non-metallic materials, fonts and graphic decorations, but PVC and other toxic vapor materials are not suitable.
About the characteristics and advantages of CNC plasma cutting machine processing:
1. High material utilization rate: the slit width can reach 0.1mm, generally in the range of 0.1~0.3. It can be finely processed, with high workpiece precision and convenient nesting.
2. Small heat affected zone: generally within the range of 0.1~0.15mm, the deformation of the workpiece is small.
3. CNC plasma cutting has no mechanical stress and surface damage.
4. The cutting section has good quality, fast speed, high efficiency, low noise and no pollution.
5. The incision can be made in any direction and can be cut from any point.
6. The technology is mature, and the CNC plasma cutting is programmed.
7. Fine machining without tool wear and without mold.
8. High degree of automation: easy to use.
Factors affecting the cutting accuracy of CNC plasma cutting machine:
1. The size of the focused spot of the plasma beam. The smaller the spot after the plasma beam converges, the higher the precision of the CNC plasma cutting machine, especially the smaller slit, the small spot can reach 0.01mm.
2. The positioning accuracy of the worktable determines the repeatability of the CNC plasma cutting machine. The higher the accuracy of the worktable, the higher the cutting accuracy.
3. The larger the thickness of the workpiece, the lower the precision and the larger the kerf. Since the plasma beam is tapered, the slit is also tapered, and the material with a thickness of 0.3MM is much smaller than the slit of 2MM.
4. The material of the workpiece has a certain influence on the precision of the CNC plasma cutting machine. In the same case, the cutting accuracy of different materials is slightly different. Even for the same material, if the composition of the material is different, the cutting accuracy will be different.
