Tips for extending the service life of cutting tools in plywood production equipment
In the production process of plywood, the wear and tear of equipment and cutting tools directly affects processing efficiency and cost. Frequent replacement of cutting tools not only increases downtime, but also leads to issues such as increased roughness and dimensional deviations on the cutting surface of the sheet metal. Therefore, mastering the techniques to extend the service life of cutting tools is crucial for improving production efficiency.
Daily maintenance is the foundation for extending tool life. Operators need to check the fastening of the cutting tools daily to avoid loosening or shifting of the blades due to vibration. During the processing, it is necessary to regularly clean the tool shaft and chip discharge channel to prevent local overheating caused by the accumulation of wood chips. Taking the rotary cutting machine as an example, after processing 500 cubic meters of poplar veneer, it is necessary to clean the gaps in the blade body with a soft bristled brush and apply anti rust oil to prevent metal fatigue.
Optimizing process parameters can significantly reduce tool wear. When rotary cutting, the feed rate needs to be adjusted according to the tree species. For example, when processing birch, the feed rate should be controlled at 1.2 to 1.5 meters per minute, while pine can be raised to 1.8 meters. The sanding process requires stabilizing the sand belt line speed at 20 to 25 meters per second to avoid exacerbating sand belt wear due to speed fluctuations. Meanwhile, controlling the moisture content of the board within the range of 8% to 12% can reduce the impact of wood fibers on the cutting edge.
By standardizing maintenance processes and adjusting scientific parameters, the tool life of plywood production equipment can be extended by more than 30%, saving significant costs for enterprises.
