Tungsten carbide circular saw blades are widely used in the cutting and processing of metal, wood, aluminum, stainless steel and other materials due to their sharpness, wear resistance and long life. However, in actual use, many users will encounter a common problem: burrs appear on the edges of the cut materials, which affects the processing accuracy and beauty, and even causes difficulties in subsequent processes.
So, why do tungsten carbide circular saw blades have burrs when cutting? How can we avoid and solve this phenomenon? This article will give you a comprehensive analysis from the causes, solutions, and daily maintenance of burrs.
1. Why do tungsten carbide circular saw blades have burrs when cutting?
The burrs generated when tungsten carbide circular saw blades are cut are not accidental, but the result of multiple factors. The main reasons can be summarized as follows:
1.1 Problems with the saw blade itself
Tooth passivation: The teeth of tungsten carbide circular saw blades that have been used for a long time are worn and blunt, and cannot effectively cut into the material, resulting in uneven and rough edges.
Inappropriate tooth shape: Different materials require saw blades with different tooth shapes. If the wrong tooth shape is selected, burrs are also prone to appear.
Saw blade jump: The saw blade is not flat enough or the center hole is worn, causing it to jump during operation and the cut is not clean.
1.2 Problems with processed materials
The material surface is uneven or there are many impurities: If the surface of the material to be cut is uneven or has impurities, it will increase friction, easily tear the edge of the cut, and produce burrs.
Soft material: Some soft materials or thin plates are more likely to be torn out of burrs.
1.3 Equipment and operation problems
Poor spindle accuracy: The axial and radial runout of the cutting equipment spindle is large, which will cause the saw blade cutting trajectory to be unstable.
Improper feed speed: Feeding too fast or too slow will destroy the stability of cutting and cause uneven cuts.
Speed mismatch: Too high or too low saw blade speed may affect the cutting quality and produce burrs.
2. How to solve the problem of burrs when cutting tungsten carbide circular saw blades?
In view of the above reasons, we can take a series of effective measures to reduce or even avoid the generation of burrs.
2.1 Check and maintain saw blades
Regularly polish the saw teeth: When the saw teeth are obviously worn and the cutting is not smooth, polish or replace the saw blade in time to ensure that the saw teeth are sharp.
Choose the appropriate tooth shape: Choose the matching tooth shape and number of teeth according to different materials. For example, a fine-toothed saw blade can be used to cut thin plates, and a large-toothed saw blade can be used to cut thick materials.
Ensure the flatness of the saw blade: Check whether the saw blade is flat before use, whether there are cracks, warping or wear on the center hole, and replace it if there is a problem.
2.2 Optimize processing materials
Material processing: Try to choose materials with a flat surface and no impurities for processing. If there is rust or dirt on the surface of the material, clean it first.
Reasonably clamp the material: Prevent the material from shifting during the cutting process and affecting the cutting quality.
2.3 Adjust equipment and parameters
Check the accuracy of the equipment spindle: Maintain the equipment regularly to ensure that the spindle runs smoothly without obvious jumps.
Adjust the reasonable speed and feed speed: Generally speaking, hard materials require slower feed and higher saw blade speed, while soft materials are the opposite. The appropriate speed and feed should be selected according to the material properties and saw blade specifications.
Set the appropriate cutting depth: It is not advisable to cut too deep at one time. It is recommended to cut multiple times to reduce burrs.
2.4 Use coolant
Tungsten carbide circular saw blades generate a lot of heat when cutting. Excessive temperature will cause the edge of the material to burn and tear, resulting in burrs. Using coolant can effectively reduce the temperature, keep the cutting smooth, and reduce burrs.
3. Daily maintenance is also important
In order to maintain the good cutting effect of tungsten carbide circular saw blades for a long time, daily maintenance and care are also very important.
3.1 Regular cleaning
After cutting, clean up the residues such as wood chips, metal chips and resin on the saw blade in time to avoid attachments affecting sharpness and heat dissipation.
3.2 Proper storage
When not in use, the saw blade should be hung or placed flat in a dry place to avoid moisture, rust or deformation.
3.3 Regular inspection
Perform regular inspections on the flatness and tooth wear of the saw blade, and handle abnormalities in a timely manner.
4. FAQs
Q1: Why does a new saw blade also have burrs when cutting?
A: If the tooth shape of the new saw blade is not suitable, it is improperly installed or the speed is set incorrectly, it may also cause burrs.
Q2: Can it be solved by grinding the burrs?
A: Yes, but it is only a remedy afterwards. It is recommended to solve the problem fundamentally and reduce the generation of burrs.
Q3: Is the slower the cutting speed, the better?
A: Not really. Too slow feed will increase friction, burn materials, and may also cause burrs. It should be adjusted to the appropriate speed.
The burrs generated when cutting tungsten carbide circular saw blades are a problem caused by many factors such as the state of the saw blade, processing materials, equipment accuracy, and operating methods. We can effectively reduce or even avoid the generation of burrs by selecting suitable saw blades, reasonable parameter adjustments, equipment maintenance, and scientific operations.
For users, they should always pay attention to the condition of the saw blade and equipment during the cutting process, and check and adjust them in time when they encounter problems. At the same time, developing good maintenance habits can not only extend the service life of tungsten carbide circular saw blades, but also improve cutting quality and work efficiency.
If the above methods cannot solve the burr problem, it is recommended to contact professionals or replace high-quality tungsten carbide circular saw blades. Only through scientific management and meticulous operation can your processed products achieve the desired effect.
