Planer Blades Cutting Chipper Knives Planer Knives, as the core components in plywood manufacturing, are meticulously engineered tools designed for the rotary cutting process. These blades are typically crafted from high-performance tungsten carbide alloys, which are renowned for their exceptional hardness and wear resistance. The manufacturing process involves precise grinding and heat treatment to ensure the cutting edge maintains its sharpness even under intense operational pressures. Some advanced blades also feature titanium nitride (TiN) coatings, enhancing their corrosion resistance and extending service life in humid production environments.​
Structurally, plywood rotary cutting blades usually adopt a long, slender strip shape, optimized for installation on rotary cutting machines. The blade's geometry, including the rake angle and clearance angle, is carefully designed to minimize cutting resistance and reduce heat generation during the slicing process. This design not only improves the efficiency of log processing but also ensures the produced veneer sheets have uniform thickness and a smooth surface finish, which are critical for the quality of subsequent plywood lamination.​
