Metal material
| Material | Material grade | Features |
| Tool steel | SK5、SK7 |
It has a low cost and high hardness, and is suitable for ordinary paper and thin cardboard (such as office paper and advertising paper). It needs to be sharpened regularly. |
| High-speed steel (HSS) | M2、M35 |
It is wear-resistant and resistant to high temperatures (suitable for high-speed cutting), and is suitable for materials of medium hardness (coated paper, cardboard). Its service life is 2 to 3 times that of tool steel. |
| Cemented carbide (tungsten steel) | YG8、YG15 |
It has extremely high hardness and wear resistance, and is suitable for hard materials (thick cardboard, corrugated paper, fiberboard). The cutting edge has a long service life, but it is highly brittle. |
| Stainless steel | 440C |
It is corrosion-resistant (suitable for paper with coatings or in a humid environment). Its hardness is lower than that of tool steel, and it is used for ordinary paper or special coated paper. |
| material | Features | apply to |
| Ceramics (Zirconia) | The hardness is HRA 90+ with long-lasting sharpness. There is no pollution of metal ions, but it has high brittleness. | High-precision slitting of label paper and films. |

Application area
Paper making industry
During the papermaking process, the paper produced is usually in large rolls. It is necessary to
use a circular knife to slit it into small rolls or flat sheets of paper in different specifications to
meet the needs of various customers. The high precision and sharpness of the circular knife
can ensure that the paper cut is neat and smooth, without burrs, thus improving the quality and
appearance of the paper.
Printing industry
The circular knife can quickly and accurately complete the cutting task, improving production
efficiency. At the same time, it ensures the accuracy of the cutting dimensions, meeting the
high-quality requirements of printed products.
Packaging industry
For the processing of packaging materials and the production of cartons of various specifications
in the field of plastic film packaging, the circular knife can be used to slit the coiled plastic
film into packaging materials of specific widths for the packaging of products.
Textile industry
Whether it is cutting large rolls of fabric into pieces of cloth of different lengths or precisely
cutting the cut pieces in the garment production process, the circular knife can, with its
efficient and accurate cutting performance, improve the efficiency and quality of fabric
cutting and reduce fabric waste.
Leather industry
The circular knife is used to cut the whole piece of leather into leather parts of various shapes
and sizes, which are used to make leather products such as leather shoes, leather bags, leather
jackets and so on. The circular knife can achieve smooth and neat cutting on the leather,
avoiding the tearing or roughness of the leather edges, which helps to improve the quality and
appearance of leather products.
Rubber industry
In the production of rubber products, such as the processing of rubber sheets, rubber hoses
and other products, the circular knife can cut rubber materials into different specifications and
shapes according to production requirements, meeting the production process requirements
of rubber products.
Basis for Material and Model Selection
| Core parameters for equipment selection and processing technology design | Specific selection |
| Material hardness |
Ordinary paper (60-100g/m²): Tool steel (SK5) or stainless steel (440C) Thick cardboard (above 200g/m²): High-speed steel (M2) or cemented carbide (YG8) Special materials (coated paper, film): Ceramic knives or knives with TiN coating. |
| Equipment speed |
Low-speed equipment (< 100m/min): Tool steel High-speed equipment (> 300m/min): High-speed steel or coated knives |
| Cutting precision |
High precision (±0.1mm): Cemented carbide or ceramic knives (the sharpness of the cutting edge ≤ 10μm) General precision (±0.5mm): Tool steel or stainless steel. |
| Equipment interface |
Installation methods: Flange type (commonly used), sleeve type, expansion sleeve type Aperture matching: Select according to the size of the main shaft of the slitting machine (such as φ25mm, φ32mm) |
Maintenance and Service Life
Sharpening cycle: Tool steel (50-100 hours) < High-speed steel (200-300 hours) < Cemented carbide (500
-800 hours)
Influencing factors of service life: Material hardness (for example, sand-containing paper accelerates wear)
sharpness of the cutting edge, and equipment stability (vibration leads to chipping of the cutting edge).
Storage suggestions: Protect with antirust oil (for metal knives), and avoid collisions (for ceramic knives).
Summary of the Selection of Circular Paper-cutting Knives
The key to model selection: clearly define the cutting material (gram weight, number of layers)equipment
parameters (speed, shaft diameter), and precision requirements.
General scenarios: Tool steel (SK5) + Conventional models (φ150-200mm)
High-end requirements: Cemented carbide/ceramics + coating technology + customized specifications
(serrated/stepped cutting edges)
