The risks in the machinery industry can be controlled through appropriate processes and methods, establishing comprehensive systems, and implementing them effectively. Woodworking saw blades, being frequently used in the wood industry, can cause injuries to individuals and result in losses for companies due to their high-speed operation and improper handling by workers.

So, how can we reduce and prevent such accidents from happening?

Firstly, it is important to have an understanding of saw blades. Saw blades consist of multiple teeth that are sharp and intact. It is a basic requirement for use that the saw blade is complete, with no missing teeth. If there are missing teeth, consecutive missing teeth should be avoided. Additionally, if there are cracks in the saw blade during practical use, it should be immediately discontinued. Manufacturers usually provide end-hole punching on the saw blades to prevent cracks, and if there is no end-hole punching, the saw blade should not be used, especially on multi-blade saws.

Once the saw blade meets the aforementioned conditions, we can proceed with machine operation. Before officially cutting the timber, it is necessary to ensure that the saw blade’s speed is normal, and there should be no wood shaking during the operation. In the case of encountering hard wood knots, a consistent feed rate should be maintained. The feeding system of multi-blade saws is designed for uniform feeding, which helps to avoid issues in this regard.

Requirements for using a multi-blade rip saw in woodworking:

When using a multiple-blade rip saw for woodworking, the following requirements should be followed:

  1. During operation, ensure that the workpiece is securely fixed and positioned correctly in relation to the cutting direction to avoid abnormal cutting. Avoid applying lateral pressure or making curved cuts. Feed the material smoothly and avoid blade impact with the workpiece to prevent blade damage or workpiece ejection, which can lead to accidents.
  2. If abnormal noise, vibration, rough cutting surfaces, or unusual odors are detected during operation, the work should be immediately stopped. Conduct a thorough inspection and troubleshoot the issue to prevent accidents.
  3. When cutting aluminum alloys or other metals, use specialized cooling lubricants to prevent overheating of the saw blade, which can cause tooth clogging and other damage, affecting cutting quality.
  4. For dry cutting, avoid continuous cutting for extended periods to prevent premature wear of the saw blade and maintain cutting efficiency. When performing wet cutting, use water as a coolant and take precautions against electrical leakage.

The quality of the saw blade plays a crucial role in multiple-blade saws for woodworking. As we know, the saw blade of woodworking machinery, such as multiple-blade saws, needs to transmit cutting forces while maintaining stability. Excellent multiple-blade saw blades have precise static geometric dimensions and high dynamic characteristics, resulting in high cutting accuracy for wood.

When multiple-blade saw blades are continuously cutting, the heat generated by the alloy teeth cutting is conducted to the saw plate, rapidly increasing its temperature. In such cases, high-quality circular multiple-blade saw plates can maintain high precision standards. Alloy teeth can be sharpened multiple times, providing a long service life. The quality of the hard alloy welding is also crucial, with thin and uniform weld seams allowing the saw teeth to withstand greater cutting forces.
