What are the characteristics of the slitting round knife
A slitting round knife is a circular tool used for cutting materials, mainly characterized by the following features:Sources：wjfilm.cn | PublishDate：2024.11.20
1、 High cutting accuracy
The blade of a slitting round knife is usually precision ground, and the edge can maintain a high degree of straightness and flatness. This enables the material to be cut correctly according to the set size and shape during the cutting process. For example, in the paper slitting industry, a slitting circular knife can correctly cut paper into strips with minimal width error, which can be controlled at the millimeter or even smaller level, meeting the needs of printing, packaging and other industries that require high paper size accuracy.
2、 High cutting efficiency
The circular design allows the scoring circular cutter to maintain continuous cutting motion during rotating cutting. Compared to some linear cutting tools, there is no need to frequently start and stop to change the cutting direction during the cutting process, greatly improving the cutting speed. Taking plastic film cutting as an example, when the cutting circular knife rotates at high speed, it can quickly cut wide plastic films into multiple narrow films, effectively improving production efficiency.
Circular cutters can usually be installed on high-speed equipment, and their excellent dynamic balance performance can adapt to higher speeds, ensuring stable operation even during high-speed cutting operations.
3、 Good stability
The circular cutting knife has good stability in mechanical structure. The center position of the cutting tool is fixed, and during the rotating cutting process, the cutting force can be evenly distributed on the circumference, reducing vibration and shaking during cutting. This is particularly important for cutting materials with hard or thick textures, such as when cutting leather materials. Stable cutting can avoid uneven leather cuts or tearing caused by tool shaking.
A good cutting round knife is generally made of high-quality steel or alloy materials, and undergoes strict heat treatment processes. The blade body has high hardness and strength, and can maintain its shape unchanged and stable cutting performance during long-term cutting work.
4、 Strong adaptability
The slitting round knife can choose different materials and blade shapes according to different materials and cutting requirements. For example, for cutting soft materials such as rubber and foam, the tool material with lower hardness but better toughness can be selected, and the cutting edge can be designed to be serrated to prevent the material from sticking to the cutting edge during the cutting process; For cutting metal materials, it is necessary to use tool materials with high hardness and wear resistance, and the cutting edge is generally flat or inclined to achieve efficient cutting.
It can also adapt to different cutting tasks by changing parameters such as tool diameter and thickness. For example, when cutting thick sheets, a circular cutting knife with a larger diameter and thicker thickness can be used to provide sufficient cutting force.
5、 Long service life
Due to the sophisticated manufacturing process of the slitting round knife, the high quality of the blade material, and the good stability during use, the blade wear is relatively slow. If cutting parameters such as cutting speed, cutting depth, etc. can be reasonably selected during the cutting process, and the cutting tools are regularly maintained, such as grinding and cleaning, the cutting round knife can be used for a longer time, reducing the cost of frequent tool replacement.
