(1) The top edge appears

1. The main saw blade is too blunt and the saw teeth are too few

2. The main saw blade is too little higher than the plate

3. If the quality of the plate is too poor, the saw blade will be blunt soon

4. Replace the saw blade again

5. Raise the main saw blade

6. Select the plate with less impurities and high quality

(2) There is edge burst below (sawn board)

1. The saw blade is too blunt

2. The width of the auxiliary saw is not enough or too narrow

3. The middle line of the main saw blade and the auxiliary saw blade does not coincide

4. Replace the saw blade again

5. Change saw blade or increase saw blade thickness

6. Readjust the left and right position of the auxiliary saw

(3) There are burning marks (on the sawn plate)

1. The alloy saw blade is too blunt and there are too many teeth on the saw blade

2. Too high speed or too slow feeding

3. Replace the saw blade and select the appropriate one

4. Select the appropriate speed and feeding speed

(4) During sawing, the workpiece is jacked up by the auxiliary saw

1. The saw blade is too blunt

2. The auxiliary saw blade rises too high

3. Replace the saw blade

4. Reduce the height of the auxiliary saw blade appropriately

(5) Edge burst of middle panel

1. The plate is thick, each piece is slightly bent and uneven, and the upper and lower parts are overlapped to form a gap

2. The cylinder pressure of mechanical pressing is not enough

3. The work piece plate surface has the stripe (concave convex) also can burst the edge

4. Press 2-3 pieces less when sawing

5. When sawing the plate, the feed speed should be adjusted to be appropriate

6. Check whether the saw blade is not sharp, and repair the edge in time
