In the aluminum profile and steel processing industry, TCT circular saw blades are widely used due to their high hardness, high wear resistance and long life. However, in actual use, many operators will find a common problem: burrs or chipping during cutting. This problem not only affects the cutting quality, but also causes material waste and even affects production efficiency. So, what is the matter with TCT circular saw blades cutting burrs or chipping? How can we deal with and prevent it? This article will give you a comprehensive analysis.

1. Introduction to TCT circular saw blades

Before going into the problem, we need to briefly understand the structure and characteristics of TCT circular saw blades.

TCT circular saw blades consist of two main parts:

Saw body: generally made of high-strength alloy steel to provide a stable structure.

Saw teeth: carbide teeth (generally tungsten steel) welded to the edge of the saw body, responsible for the actual cutting work.

The advantages of TCT circular saw blades include:

Long life and good wear resistance;

Suitable for a variety of materials, such as wood, metal, plastic, etc.;

High cutting accuracy and high efficiency.

However, even the best TCT circular saw blades may have problems if used improperly, such as: burrs, chipping, heat or vibration during cutting.

2. Common reasons for burrs or chipping of TCT circular saw blades

To solve the problem, we must first find the root cause. The following are several common reasons:

2.1 Saw blade problem

Saw tooth dullness: Long-term use without timely replacement or grinding causes the saw teeth to become blunt and the cutting to become rough.

Saw tooth breakage or missing: Local tooth damage will cause uneven cutting pressure, resulting in chipping or tearing.

Saw blade model does not match the material: For example, using a saw blade for cutting wood to cut aluminum or plastic will result in uneven cuts.

2.2 Improper cutting parameter settings

Too high or too low speed: Different materials need to match the appropriate linear speed. Too high may burn the blade, and too low may pull the material.

Improper feed speed: Feeding too fast can easily tear the material, and too slow may cause saw tooth wear and burrs.

2.3 Equipment problems

Spindle runout or unbalanced saw blade installation: will cause unstable cutting and cause the cut edge to break.

Unstable clamping: the material is not firmly fixed, and the cut edge will break when vibrating.

2.4 Problems with the cut material

Poor quality of the material itself: for example, there are holes, cracks or impurities in the board, which is easy to break.

Laminating and edge-wrapped materials: If there is a coating on the surface of materials such as particleboard and density board, it is more likely to break the edge.

3. Solutions to TCT circular saw blade cutting burrs or broken mouth

After finding the cause, the next step is to prescribe the right medicine and solve them one by one.

3.1 Check and replace the saw blade

Regularly check the condition of the saw teeth, find bluntness or notches, and grind the teeth or replace the new saw blade in time.

Choose the appropriate type of TCT circular saw blade, and choose different tooth types for different materials (such as ATB, TCG, FT, etc.).

Use brand products: The manufacturing process of high-quality TCT circular saw blades is more precise, and the cutting quality is more guaranteed.

3.2 Optimize cutting parameters

Set reasonable spindle speed and feed speed according to the manufacturer's recommended parameters or material type.

Wood: higher linear speed, moderate feed;

Plastic: low speed to prevent melting;

Aluminum: high-speed cutting, cooling and lubrication.

Use frequency converter to accurately control the speed and flexibly adjust according to the material.

3.3 Maintenance equipment and operating specifications

The connection between the spindle and the saw blade needs to be regularly maintained to avoid yaw.

The saw blade needs to be installed firmly in place to avoid swinging.

Use guide rails and pressure devices to ensure that the cut material is firm and vibration-free.

3.4 Optimize processing methods for materials

For boards that are prone to edge bursting (such as veneer boards), "pre-cutting + main cutting" can be used for two cuttings to effectively avoid edge collapse.

Use anti-edge collapse saw blades, such as saw blades with negative rake teeth design.

For surface materials, tape can be applied to the back to reduce the possibility of collapse.

4. TCT circular saw blade purchase suggestions: the first step to improve cutting quality

A good saw blade is better than a hundred debugging.

When buying TCT circular saw blades, pay attention to the following aspects:

4.1 Number of teeth and tooth shape

More teeth: smoother cutting, but slightly lower efficiency;

Fewer teeth: suitable for rough processing, high efficiency but easy to burr;

Tooth shape selection depends on the material: TCG (ladder flat teeth) is recommended for cutting aluminum, and ATB (staggered teeth) is recommended for cutting wood;

4.2 Saw blade thickness

Thin slices have high cutting accuracy, but stable equipment is required;

Thick slices are suitable for large-scale rough processing;

4.3 Saw blade diameter and aperture

Match with sawing machine equipment specifications;

The center hole needs to fit perfectly with the spindle to avoid eccentric operation.

4.4 Coating and carbide material

Some TCT saw blades have heat-resistant coating or wear-resistant treatment, which has a longer service life;

Whether the carbide tooth material is imported tungsten steel directly affects the cutting quality and cost ratio.

5. Daily maintenance tips for TCT circular saw blades

If you want the saw blade to last longer and cut more steadily, you also need to master daily maintenance skills:

Cleaning saw teeth: clean the resin, asphalt and other residues on the saw teeth in time after cutting.

Check the saw body regularly for cracks and deformation.

Use a special grinder to grind teeth, never grind manually or use inferior tools.

Store in a dry, shockproof, and rust-proof environment to avoid collision.

In the modern processing industry, TCT circular saw blades are one of the core tools to improve production efficiency and processing quality. But no matter how good the saw blade is, improper use may cause burrs or chipping.

Mastering the correct operating method, choosing the right saw blade model, and regularly maintaining equipment and tools are basic skills that every manufacturer and processing operator should pay attention to.

If you are facing the problem of burrs or chipping on the TCT circular saw blade, you might as well check and optimize them one by one from the perspectives mentioned in this article. I believe that it will bring a qualitative improvement to your processing efficiency and finished product quality.
