Example Embodiment
[0026] Example 1
[0027] This embodiment provides a method for preparing a wood-based panel saw, including the following steps:
[0028] S1. The cemented carbide and polyethylene glycol are uniformly mixed and then ball milled. The main components and mass percentages of the cemented carbide are: 1.5% Co, 0.5% Ni, 0.35% Cr 3 C 2 , 0.1% Re, the balance is 0.4μmWC; the amount of polyethylene glycol is 2% of the cemented carbide;
[0029] S2. Put the ball-milled mixture in step S1 into the saw-tooth mold, and press and form it. The molding pressure is 65MPa;
[0030] S3. Vacuum sinter the saw blade base blank and the saw blade saw tooth blank. The sintering process parameters are as follows: the temperature is 1450°C and the time is 60 minutes to obtain the saw blade base and saw blade saw teeth;
[0031] S4. Weld the saw blade teeth on the saw blade base body, after grinding, coating and coating, the wood-based panel saw is obtained.
