One, How to cut particleboard without splintering
1、Sudden spike
Reasons: ① The main saw blade is too dull with too few teeth; ② The main saw blade is too high relative to the board; ③ The board quality is poor, leading to rapid blade dulling.
Solutions: ① Replace the saw blade; ② Raise the main saw blade; ③ Use high-quality wood panels with minimal impurities.
2、The following issue has arisen（Sawn lumber）
Reasons: ① The saw blade is too dull; ② The saw blade width is insufficient or too narrow; ③ The center lines of the main and auxiliary saw blades do not align.
Solutions: ① Replace the saw blade; ② Replace the saw blade or increase the saw blade thickness; ③ Re-adjust the position of the left and right auxiliary blades.
3、There are signs of burning (on the sawed wood)
Reasons: ① The saw blade is too dull, with too many teeth; ② The speed is too high or the feed rate is too slow.
Solutions: ① Replace the saw blade with an appropriate one; ② Select an appropriate speed and feed rate.
4、During cutting, instances of workpieces being caught by the secondary blade have been observed.
Reasons: ① The saw blade is too dull; ② The saw blade is raised too high.
Solutions: ① Replace the saw blade; ② Adjust the height of the auxiliary blade.
5、Apply panel edge flashing
Reasons: ① The thickness of the board is relatively large, resulting in uneven micro-bending and gaps when the top and bottom surfaces are overlapped. ② The pneumatic cylinder pressure is insufficient. ③ Surface patterns (undulations) on the workpiece can also cause edge chipping.
Solutions: ① When sawing, apply less pressure to 2-3 pieces of the board. ② Adjust the cutting speed of the board to a suitable level. ③ Check if the saw blade is dull and sharpen it promptly.
Two. What are the causes of splintering on the edges of particleboard?
1、Reasons for operation
During the maintenance and restoration phase, particleboard undergoes high-temperature pressing during lamination. After lamination, the temperature of the board is high, which can negatively impact its physical properties. Therefore, a maintenance and restoration phase is necessary. The recommended procedure involves storing the laminated product flat, ensuring even support on both sides, and allowing the board to fully cool and dissipate heat before cutting and applying. This process effectively minimizes edge chipping and warping of the laminated surface.
2、 Reasons for applying the facing material.
When pressing at too high a temperature or for too short a time, the decorative paper does not adhere well to the substrate. If the decorative paper is stored for too long, or if insufficient adhesive is used during the adhesive application process, the bonding between the decorative paper and the substrate during pressing will be weak, resulting in chipping or edge defects when cutting.
3、Due to the inherent properties of particleboard material.
The bonding strength of the particleboard surface is insufficient, the thickness of the board blanks for panel fabrication is inadequate, and the surface solidification layer is not fully sanded during uniform thickness sanding; the thickness deviation of the board blanks is significant, resulting in localized sand leakage during uniform thickness sanding. Consequently, some areas are sanded excessively, causing the fine surface layer to be completely sanded, resulting in a coarse particle core layer. This does not affect the lamination, but causes chipping during cutting. The fine surface layer of the particleboard is too rough, and the board surface hardness is too high, which can all cause chipping during cutting.
