How to prevent blade burning and select multi-blade saws?
Feb 16,2022
Blade burning in multi-blade saws is a common and difficult-to-solve problem in wood processing plants. The quality of the saw blade directly affects processing efficiency and product quality. The worst-case scenario for a multi-blade saw is blade burning, which directly leads to blade scrap and impacts work progress.
Main causes of blade burning in multi-blade saws
1. Poor heat dissipation. When buying saw blades, it's best to use those with cooling holes, and you can add water or other coolants to lower the temperature.
2. Too many teeth. Multi-blade saws have many blades installed, resulting in high resistance. More teeth mean greater resistance, making blade burning more likely.
3. Poor discharge. Sawdust that is difficult to discharge can also cause local overheating. Equipment must have a good discharge system.
4. Raw materials. Particleboard is inherently difficult to saw. If the particleboard quality is poor and contains too many impurities, blade burning is more likely.
Several areas need to be checked during actual operation
1. Check if the water tank is clogged
2. Check if the water level is sufficient
3. Check if the main shaft is misaligned
4. Check if the guide shaft and main shaft are on the same plane
5. Check if the feed chain is balanced with the saw blade
Make appropriate adjustments after inspection.
The quality of multi-blade saw blades varies greatly. Be sure to choose high-quality multi-blade saw blades. Don't buy cheap, low-quality blades, as this will not only delay production but may also cause mechanical accidents.
Correct steps for purchasing multi-blade saws
1. Check the brand: Good brand multi-blade saws have undergone customer testing and continuous improvement, ultimately gaining customer recognition. Good brand multi-blade saws are supported by strong technical teams. Multi-blade saws produced by small workshops lack guarantees in terms of technology and safety.
2. Check the rationality of the multi-blade saw design: A good multi-blade saw is mainly reflected in smooth feeding, no blade burning during sawing, and high precision of the processed boards.
3. Check the materials used in the multi-blade saw equipment: Durable equipment must be supported by high-quality accessories.
4. Check the weight of the machine: Weight can most directly reflect the quality of the machine.
Correct techniques for selecting saw blades for multi-blade saws
Based on the material you are processing, if it is relatively soft wood such as fir or pine, the kerf can be based on the manufacturer's recommendations. For hardwood or mixed wood, for domestic multi-blade saw blades, the kerf and steel plate should be processed to ensure blade strength, or import saw blades can be selected, and the kerf can be smaller.
Considering the yield, you can adjust the kerf based on your usual usage.
