What are the characteristics of a flat edged round knife
Flat mouth round knife is a common cutting tool with the following characteristics:Sources：www.hafc.net.cn | PublishDate：2024.12.18
1. Blade shape
Flat mouth design: The blade is in a straight line without any curvature or wave shape. This flat mouth design allows the tool to provide a relatively stable cutting surface during cutting operations. For example, when cutting paper, a flat edge can ensure a smooth cut without wavy or uneven edges, which is very important for situations that require high-precision cutting, such as post production of printed materials, handmade origami art, etc.
Circular blade: The overall blade is circular, which gives the tool good rotational performance. During use, the circular knife can cut by rotating, reducing the friction between the blade and the material during cutting, making the cutting smoother. For example, when cutting soft materials such as rubber and leather, a rotating circular knife can easily cut into the material and is not easily stuck by the material.
2. Cutting method
Rotary cutting is the main method: Flat mouth circular knives usually achieve cutting function through rotation. This rotary cutting method can evenly distribute the cutting force on the blade, reducing the situation of excessive force on a single point. Taking cutting fabric as an example, when the flat edged circular knife rotates, each point of the blade comes into contact with the fabric in sequence and cuts, which can avoid tearing the fabric or damaging the blade due to excessive force on a certain point.
Suitable for continuous cutting: Due to its rotating cutting characteristics, flat edged circular knives are very suitable for continuous cutting operations. For example, in industrial production, when used to cut rolls (such as plastic film rolls, paper rolls, etc.), a circular knife can continuously rotate and cut along the width direction of the roll, efficiently dividing the roll into the desired width and ensuring the neatness of the cutting edge.
3. Application scope
The advantages of cutting soft materials are obvious: the cutting effect on soft materials is better. In addition to the aforementioned rubber, leather and cloth, it is also suitable for cutting materials such as foam plastics. When making foam plastic products, the flat mouth round knife can correctly cut large pieces of foam into various shapes and sizes, and because its cutting process is relatively stable, it can reduce the production of foam chips.
Widely used in some industrial fields: widely used in industrial fields such as printing and packaging. In the printing industry, it is used to cut the edges of printed materials to achieve standard sizes; In the packaging industry, it is used to cut cardboard, plastic packaging materials, etc., and help produce various packaging boxes, bags, and other products.
4. Accuracy and stability
Being able to maintain a certain level of cutting accuracy: Under appropriate operating conditions, flat edged circular knives can achieve high cutting accuracy. This is due to the combination of its flat blade and rotary cutting method. For example, in the cutting of packaging materials for some precision electronic devices, a flat edged circular knife can correctly cut materials such as packaging liners that meet the size of the equipment, and the error can be controlled within a small range.
Good stability: Its structural design ensures high stability of the cutting tool during the cutting process. Compared to some irregularly shaped cutting tools, the axis position of a flat edged circular tool is relatively fixed during rotation, making it less prone to shaking or displacement. This is very important in situations where deep cutting is required or there are strict requirements for the cutting path, such as cutting multi-layer composite materials.
