The role of CNC cutting machines in industrial development is undeniable. However, many small manufacturers still hesitate to adopt these machines for cutting tasks. The main concern is that ordinary employees may not be able to operate the equipment effectively. Therefore, having skilled personnel who understand how to use CNC cutting machines is 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. In real-world applications, external factors such as the shape of the steel plate, the size of the parts being cut, and the thickness of the material can significantly affect the process. It's crucial to know in advance where the cutting torch should be positioned relative to the surface and the distance from which it should start cutting.
With proper design, companies like Shanxi Huaheng have gathered insights from numerous end users and summarized two key points:
1. **Using a reasonable cutting height**
The so-called "cutting height" refers to the distance between the torch and the cutting surface. This distance is mainly influenced by the material being cut, its thickness, and the type of fuel used. When adjusting the cutting height, you can rely on the instructions provided by the manufacturer. Additionally, upgrading the machine with hardware features like an automatic height adjustment system can enhance performance and accuracy.
2. **Designing the starting point position**
When using a CNC cutting machine, it’s generally recommended to set the cutting starting point at the edge of the steel plate. For plasma cutting, it's best to avoid the "pierce-cut" method, as it can wear down components faster. Instead, align the nozzle directly at the edge of the workpiece before igniting the plasma arc. To improve the quality of the cut, adding a small lead-in section when cutting from the edge can help produce a cleaner, more consistent slit.
In general, when using plasma cutting with perforation, it's advisable to start the cut from a distance that is at least twice the normal plasma arc height or the maximum height the system can handle. This helps ensure better control and improves overall cutting efficiency.
Buffer ring is a common Machine element, which is used to reduce the vibration and noise generated during the operation of the machine. Buffer rings are mainly divided into two types: rubber buffer rings and spring buffer rings. Rubber buffer rings are suitable for low-frequency vibration and impact, while spring buffer rings are suitable for high-frequency vibration and impact. Buffer ring is an important Machine element, which is widely used in automobile, machinery, electronics and other fields.
