The role of CNC cutting machines in industrial development is undeniable, yet many small manufacturers still avoid using them for cutting tasks. The main concern is that ordinary workers may find it difficult to operate the equipment. Therefore, having some expertise in operating CNC cutting machines remains essential.
As the name suggests, a CNC cutting machine uses a numerical control system to follow a pre-set cutting path and perform precise cuts. However, in real-world applications, external factors such as the shape of the steel plate, the size of the parts to be cut, and the thickness of the material can influence the process. It's crucial to know in advance where the cutting torch should be positioned relative to the surface and how far it should be from the cutting area. With proper design, Shanxi Huaheng has gathered insights from numerous users and summarized the following two key points:
1. **Using an appropriate cutting height**
The so-called cutting height refers to the distance between the torch and the cutting surface. This distance is mainly affected by the type of material being cut, its thickness, and the fuel used. When adjusting the cutting height, you can rely on the manufacturer’s guidelines for visual control. Additionally, you can enhance the machine’s performance by upgrading hardware, such as adding an automatic height adjustment system to ensure consistent and accurate cutting.
2. **Designing the starting point position**
When using a CNC cutting machine, it's generally recommended to place the cutting start point on the edge of the steel plate. For plasma cutting, we advise avoiding the "pierce-cut" method, as it can reduce the lifespan of wearing parts. Instead, align the nozzle directly at the edge of the workpiece before initiating the plasma arc. To improve the quality of the cut, it's also advisable to add a short lead-in section when cutting from the edge.
In general, when using plasma cutting, it's best to keep the initial piercing distance at least twice the normal cutting height or the maximum height the plasma arc can reach. This helps maintain better control and ensures higher-quality results.
