Method for improving service life of aluminum alloy saw blade


Aluminum alloy saw blade is the most commonly used cutting tool for wood products processing. The quality of aluminum alloy saw blade is closely related to the quality of processed products. Choosing the right aluminum alloy saw blades is of great significance to improve product quality, shorten cycles, and reduce costs. Here are some ways to improve the life of aluminum alloy saw blades.

The substrate requires a material that is good enough in heat resistance, with high toughness, good strength, low stress, small deformation and small end jumps. The depth angle of the substrate tooth need to be same for each piece of the substrate, the hole fitting tolerance is high. The material density, thickness and hardness should be even.

Each process must formulate a reasonable process, strict inspection and strict inspection according to the process, the reasons that affect the quality of the tool are very complicated, the previous process is not well controlled, and the end result is endless. As long as careful and careful analysis of all factors can be resolved.

Try to use low-temperature silver electrodes and fluxes with good fluidity to prevent sudden and sudden temperature drop in the workshop. In principle, the temperature of the welding teeth is not allowed to exceed 750 °, to ensure that the temperature of each welding tooth is uniform and the welding is separated. Bilateral heating is used to keep the temperature of the alloy and the substrate substantially the same, to ensure that it is placed in an oven after welding to eliminate welding stress, refine the alloy crystals, and maintain welding strength.

The key to the durability of the tool is the cutting edge. The cutting edges of each surface are not ground in place and the resistance is large. The grinding wheel is too thick to notice the marks of the grinding wheel. Belt, runout keep the minimum runout, the side rake angle should be small, the back edge angle should not be too large, the rotation direction of the grinding head and the radial cutting force should be selected from low to high Grinding angle and trailing edge angle, rake angle and leading edge angle are the last part of tool manufacturing. Violation of the previous process will bring quality effects to the tool.
