CNC plasma cutting machine is a popular cutting method in the current market. It occupies half of domestic cutting equipment together with CNC flame cutting machine. And the current fine CNC plasma cutting machine is no less than the laser cutting machine in terms of cutting speed or cutting quality. Speaking of cutting quality, I believe many people are not very clear about the evaluation criteria of the cutting quality of CNC plasma cutting machines. Today, I will give you a detailed introduction: The evaluation criteria of the cutting quality of the CNC plasma cutting machine mainly include five aspects: the width of the notch, the surface roughness, the squareness of the edge of the notch, the width of the heat-affected zone, and the amount of suspended slag. The specific requirements are as follows: First, the width of the cut: The width of the incision is one of the most important characteristic values ​​for evaluating the cutting quality of the cutter, and also reflects the radius of the smallest circle that can be cut by the cutter. It is based on the size of the incision at the widest point, most plasma cutting machine incision width between 0.15 ~ 6mm. Second, the surface roughness: It is used to describe the appearance of the cut surface and determine if rework is required after cutting. It is a measure of the Ra value on the cross-section of the incision depth at 2/3. As the result of the action of the cutting air flow in the longitudinal direction of the cutting advance, the main form is the cutting corrugation. The surface roughness of plasma cutting is higher than that of flame cutting, but lower than laser cutting. Third, the squareness of the cut edges: It is also an important parameter that reflects the quality of the cut and relates to the degree of rework that is required after cutting. Therefore, it is very important to control the squareness of the cut edges. Fourth, the width of the heat affected zone: This index is very important for those hardenable or heat-treatable low-alloy steels or alloy steels. Excessively wide heat-affected zone widths can significantly change the performance near the incision. Fifth, the amount of slag: It is to describe how much oxide slag or resolidified material adheres to the lower edge of the cut after hot cutting. When we evaluate the cutting quality of CNC plasma cutting machines, we can observe from the above five aspects. However, the five standards are not the only ones. There are other standards. Since the cutting quality is very important for CNC plasma cutting machines, what steps should we take in production to improve cutting quality? Based on its own production experience, Wuhan Naval CNC has summarized the following points: The first, CNC plasma cutting machine must be closely integrated with the functional components. The clearance between the bearing and the pin hole should not be too large, because the cutting process is carried out simultaneously with the movement of the casting billet. The loosening of each part will cause the swing of the cutting torch and further affect the cutting effect. Second, the swing of the cutting gun in the cutting machine and the positioning control ramp should not be short. Thirdly, the position of the torch must be fixed, highly reasonable and vertical, and there must be no deviation between the front and the back. Fourth, the choice of plasma power must be matched with the thickness of the cutting material, otherwise it will directly affect the cutting quality of the CNC plasma cutting machine.

A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and release it to the atmosphere to lower the water temperature.
Closed Cooling Tower has two operation modes.
Air cooling, air cooling + spraying.
The electronic control system actively stops the two switching modes according to the requirements of working conditions to save energy and reduce consumption.
