Publish Time: 2023-05-31     Origin: Site

Circular Slitter Blade is a cutting tool used in industrial production, it is usually made of high-speed steel, carbide, ceramics and other materials, and has circular teeth.


The Circular Slitter Blade is mainly used for longitudinal or transverse cutting of various materials, such as paper, plastic film, aluminum foil, tape, fabric, etc. They can also be used for quantitative cutting and cutting into rolls. Circular Slitter Blade is widely used in many industries, such as packaging, printing, food processing, pharmaceuticals and electronics.

Circular Slitter Blade


The Circular Slitter Blade cuts by placing the material under the blade and pressing the rotating blade into the material. The number, shape and arrangement of the teeth affect the cutting performance of the Circular Slitter Blade. For example, straight teeth are good for thinner materials, while curved teeth are better for thicker materials.


The Circular Slitter Blade is a very important cutting tool that plays a vital role in many industries. At the same time, it also needs to choose different materials according to different process requirements and understand the principles of its tooth arrangement.


How to choose Circular Slitter Blade?


Cutting material: First, you need to determine the type of material you need to cut, such as paper, metal, plastic, etc. Different materials have different requirements for cutting blades, such as hardness, wear resistance, etc.


Cutting speed: Cutting speed is also an important factor affecting blade selection. If you need high-speed cutting, you need to choose a blade suitable for high-speed operation.


Diameter size: The diameter of the blade is usually selected according to the size of the material to be cut. The larger the diameter, the higher the cutting accuracy, but the speed may be reduced.


Tooth count and shape: Tooth count and shape are also factors to consider when choosing a blade. Generally speaking, the more teeth, the better the cutting effect, but too many teeth will also affect the cutting speed. In addition, different shapes of teeth are suitable for different types of materials, such as round teeth for soft materials and serrated teeth for hard materials.


Material selection: The material from which the blade is made is also a very important factor. Common blade materials include high-speed steel, carbide, ceramic, and diamond coating, among others. Proper material selection can improve cutting efficiency and blade life.


Cutting quality: In addition to the above factors, it is also necessary to consider the cutting quality of the blade, such as flatness, finish, etc. These factors also affect the cutting effect and product quality

Common manufacturing materials for Circular Slitter Blade

High Speed Steel (HSS): HSS is an alloy steel commonly used in cutting tools with high hardness, wear resistance and corrosion resistance. HSS cutting blades are widely used in cutting and separating tasks of medium-strength materials.


Carbide: Cemented carbide consists of materials such as tungsten, cobalt and carbon, and is widely used as a manufacturing material for cutting tools. Carbide cutting blades have extremely high hardness, wear resistance and corrosion resistance, and are suitable for cutting high-strength and high-hardness materials.


Ceramic: Ceramic cutting blades are usually made of materials such as aluminum oxide or silicon nitride. Ceramic cutting blades have very high hardness and wear resistance, and can withstand high temperature environments, so they are suitable for cutting special materials or cutting in high temperature environments.


Composite materials: Composite materials include diamond-coated blades and blade surface-coated ceramics. These materials are extremely hard, wear and corrosion resistant and can be used to cut special materials or cut in harsh environments.


In general, which material to choose depends on the desired cutting task and the environment of use. Each material has its advantages and disadvantages, so various factors need to be considered to determine the most suitable blade material.

Precautions for using Circular Slitter Blade

Proper Installation

When installing a Circular Slitter Blade, the blade should be carefully inspected for damage or defects. Then fit the blade properly onto the disc, making sure the blade fits the disc contour. Finally, tighten the blade screws and check that the blade is securely mounted.


Check Before Use

Before using the Circular Slitter Blade, you should check that the tool is clean and the blade is sharp. If the blade is found to be blunt or damaged, it should be replaced in time.


Proper RPM

Make sure the Circular Slitter Blade is running at the proper RPM. Too fast a speed can cause the blade to overheat or cut poorly; too slow a speed can cause material buildup or a dirty cut.


Regular Maintenance

To keep your Circular Slitter Blade performing at its best, regular maintenance should be done. This includes cleaning the blades and discs, lubricating mechanical parts, and replacing blades as needed.


Safe Use

When using Circular Slitter Blade, use caution. Appropriate safety glasses and gloves should be worn, fingers should be avoided in the cutting area, and the workplace should be clear of debris and obstructions.


Learn Operating Skills

Before starting to use the Circular Slitter Blade, you should be familiar with the relevant operating skills and seek help and advice from experienced operators. This can help you better understand how to use the tool properly and how to stay safe while using it.
