Plasma cutting machine quality identification

plasma cutting machine is a kind of processing equipment that uses the heat of high-temperature plasma arc to partially melt (and evaporate) the metal at the cut of the workpiece, and uses the momentum of high-speed plasma to remove the molten metal to form the cut.
plasma cutting machine is widely used in cutting automobiles, motorcycles, pressure vessels and other industries. It has the characteristics of precise digital control of cutting length and easy operation. It can not only cut various metals that are difficult to cut by oxygen cutting, such as stainless steel, aluminum, copper, cast iron, carbon steel, etc., but also has fast cutting speed, narrow slit, flat cut, small heat-affected zone, low workpiece deformation, simple operation, and significant energy-saving effect.
In the case of plasma cutting machine quality appraisal, Zhongke Testing can provide plasma cutting machine quality appraisal services.

can be divided by type: desktop CNC plasma cutting machine, gantry CNC plasma cutting machine, portable CNC plasma cutting machine;
can be divided by working method: dry plasma cutting machine, semi-dry plasma cutting machine, underwater plasma cutting machine;
can be divided by cutting quality: ordinary plasma cutting machine, fine plasma cutting machine, laser-like plasma cutting machine, etc.

was entrusted by the court to conduct an appraisal and analysis on "whether there are quality problems" with the plasma cutting machine involved in the case.
identification analysis results:
identification analysis expert group discussed the relevant information and on-site investigation of the plasma cutting machine involved and conducted a comprehensive quality and technical analysis, and made the following suggestions and conclusions:
plasma cutter has the following quality problems:
1. AC servo motor: The on-site nameplate shows that the actual value is 0.75KW, which is inconsistent with the technical agreement (400W);
2, the actual measured value of the horizontal effective maximum cutting length (effective cutting width) is: 3860MM, which is smaller than the technically agreed value of 4000MM; the actual measured value of the longitudinal maximum stroke (effective cutting length) is: 118 13MM, less than the technically agreed value of 12000MM;
3, refrigeration dryer: the actual model shown on the on-site nameplate is inconsistent with the technical agreement;
4, gas storage tank: the actual brand on site is Ruide, which is inconsistent with the technical agreement;
5, lack of mechanical limit, inconsistent with the technical agreement The agreement is inconsistent;
6, after cutting and drilling steel plates of different specifications with a thickness of 10MM-60MM on site, there are cases where the cutting accuracy and small hole cutting accuracy of the cut workpiece do not meet the JB/T10045.1-10045.5-1999 "Thermal Cutting" standard and the verticality of some edge cuttings does not meet the requirements of the technical agreement.
