The circular knife cutting machine can provide good cutting effect, smooth and flat edges, no burrs, loose edges, patterns, and no laser cutting burnt edge effect. However, due to the physical properties of the circular knife, it may overcut when cutting thick materials, especially when the material thickness increases, this phenomenon will be more obvious. Therefore, when choosing a knife, it is necessary to comprehensively consider factors such as material thickness, air permeability, and cutting accuracy requirements.
The main difference between circular knives and oscillating knives is their working principle and applicable materials. Circular knives use the rotation of the blade for cutting, which is suitable for materials with strong air permeability, such as fur, mesh cloth, etc. Since the blade is round, when cutting thick materials, the curvature may cause the upper and lower cutting distances to be different from the middle cutting distance, resulting in overcutting. The vibration knife uses the vertical vibration of the blade to cut, which is suitable for cutting multi-layer materials and plates. It has fast cutting speed and good effect, and the cutting effect of multi-layer materials is also very good.
