In modern metal processing, wood processing and various industrial fields, tungsten carbide circular saw blades are widely used as an efficient and durable cutting tool. When many people choose and use tungsten carbide circular saw blades, they often pay attention to parameters such as the number of teeth, outer diameter, inner hole, etc., but rarely realize the importance of thickness to the cutting effect. In fact, the thickness of tungsten carbide circular saw blades not only affects the cutting efficiency, but also directly affects the quality of cutting, material waste, equipment load and service life. This article will deeply explore the influence of tungsten carbide circular saw blade thickness on cutting effect from multiple dimensions to help everyone choose and use tungsten carbide circular saw blades more scientifically.

1. Common specifications of tungsten carbide circular saw blades

The thickness of tungsten carbide circular saw blades usually refers to the thickness of the saw blade body, also called the matrix thickness. Some products also mention the tooth thickness, which is the widest part of the saw teeth. The sawtooth width is often slightly larger than the matrix thickness, which is used to ensure that the width of the saw seam is larger than the matrix to avoid friction and jamming.

The thickness of common tungsten carbide circular saw blades is generally between 0.8mm and 6mm, depending on the diameter of the saw blade, purpose, and equipment. For example:

Small-diameter saw blades are usually thinner and suitable for precision cutting.

Large-diameter saw blades are thicker to ensure rigidity and stability.

2. The influence of thickness on cutting quality

2.1 Cutting surface flatness

The thinner the tungsten carbide circular saw blade, the narrower the saw kerf, the smaller the friction resistance, the more delicate and smooth the cut, and it is suitable for processing with high precision requirements. Especially when cutting softer materials such as wood and aluminum, thin blades can reduce burrs, burns and edge collapse.

On the contrary, thick saw blades are more likely to cause rough cuts and even leave ripples due to wide saw kerfs, large friction and large cutting forces.

2.2 Cutting accuracy

Thin saw blades have poor rigidity and are prone to swing and offset due to uneven force, affecting the straightness and dimensional accuracy of the cut. Therefore, in situations where high rigidity and high stability are required (such as cutting thick steel plates and hard materials), it is more appropriate to choose thicker saw blades.

When cutting thin plates, fine processes, and workpieces with high precision requirements, thinner saw blades can be used to obtain smaller kerfs and higher precision.

3. The influence of thickness on cutting efficiency

3.1 Cutting resistance

When thick saw blades are cutting, the sawing kerf is wide, the amount of material cut is large, and the friction area is large, which will increase the cutting resistance, thereby reducing the cutting speed and increasing power consumption.

Thin saw blades can improve cutting speed and efficiency due to their narrow cutting kerf, small cutting amount, and small resistance.

3.2 Energy consumption and cost

Since thin saw blades reduce material loss and cutting resistance, the power consumption and processing cost are relatively low, which is particularly suitable for high-frequency and large-scale production. Thick saw blades will consume more energy and materials.

4. The influence of thickness on the life of saw blades

4.1 Wear resistance

Thick saw blades have better rigidity and stability, are not prone to vibration and deformation, and the saw teeth wear more evenly, which is suitable for long-term and high-intensity work.

Although thin saw blades cut lightly, they are prone to heat deformation, fracture, and rapid wear of the tooth tip, and need to be replaced or sharpened more frequently.

4.2 Safety

Thick saw blades are more stable when rotating at high speeds, are not prone to fracture or warping, and are safer. Thin saw blades are more fragile in structure and are easily damaged by overload and improper operation.

5. Matching of thickness and processing materials

Different materials have different requirements for saw blade thickness:

Wood: softer in texture, thinner saw blades can be selected to improve efficiency and cutting quality.

Aluminum: medium hardness, thin saw blades and medium thickness are both OK, but thermal deformation should be prevented.

Metals such as stainless steel and carbide: high hardness and high resistance, thicker saw blades should be selected to ensure rigidity and stability.

If thin saw blades are used to cut hard materials, it is easy to break teeth, offset, or even break.

6. Thickness adaptability to equipment

Different equipment also has requirements for saw blade thickness. High-power and large cutting machines can drive heavy saw blades with good stability. Some small table saws or portable saws are more suitable for thin saw blades, otherwise the motor load is too large, and it is easy to burn or power off.

In addition, thin saw blades have higher requirements for the balance and clamping accuracy of the machine spindle, otherwise it is easy to swing, heat up, or even dangerous.

7. How to choose the appropriate thickness of tungsten carbide circular saw blade?

According to the cutting material: thin slices are used for soft materials, and thick slices are used for hard materials.

According to the cutting accuracy requirements: thin slices are used for high-precision processing, and thick slices can be used for rough processing.

According to the equipment power: high power can be equipped with thick slices, and low power should be selected for thin slices.

According to the working environment: choose thin slices for mass production and cost control, and choose thick slices for safety and durability.

VIII. Common misunderstandings and precautions

Misunderstanding 1: The thinner the better

Many people mistakenly believe that the thinner the saw blade, the sharper it is. In fact, too thin saw blades are prone to bending and tooth collapse under inappropriate working conditions, which affects quality and safety.

Misunderstanding 2: Thick slices do not require maintenance

Although thick slices have good rigidity, they will also be damaged if used improperly (such as too high speed and insufficient cooling).

Precautions:

Regularly check whether the saw blade is worn or deformed.

Choose a thickness that matches the equipment and material.

Operate according to the speed and feed speed recommended by the manufacturer.

Add coolant to cool down when cutting hard materials.

In summary, the thickness of tungsten carbide circular saw blades has a significant impact on the cutting effect. Thin saw blades are suitable for high-efficiency, low-resistance, and precision cutting, but they have poor rigidity and are easy to wear; thick saw blades are stable, durable, and safe, but they have large cutting resistance and low efficiency. Therefore, when choosing a tungsten carbide circular saw blade, it is necessary to comprehensively consider factors such as cutting materials, processing accuracy, equipment capabilities, and production costs, and select the most suitable thickness to ensure processing efficiency, improve cutting quality, and extend tool life.

Correctly understanding and reasonably selecting the thickness of tungsten carbide circular saw blades can not only improve processing quality, but also effectively reduce production costs and safety risks. I hope that the analysis in this article can provide valuable reference for your production practice.
