At present, diamond is widely used in stone, concrete and aluminum cutting.
How to test the quality of diamond saw blade has always been the research work of many saw blade manufacturers and saw blade users.
Now, before leaving the factory and entering the market, each diamond saw blade will generally carry out the following four inspections.
1. Appearance inspection
When we do appearance inspection for diamond saw blade, we usually use visual inspection or 10 times magnifying glass for inspection, and cooperate with vernier caliper with graduation value of 0.02mm for inspection. The main content of the detection is to check whether there is crack in the saw tooth of the diamond saw blade and whether the diamond particles on the saw tooth are evenly distributed. At the same time, if the base surface of the saw blade is painted, it is necessary to check whether the coating is uniform, flat, scratched and whether the weld is full.
2. Geometric dimension inspection
It is an important link for the quality inspection of diamond saw blade to check the geometric dimension of diamond saw blade. Among them, the quality inspection of the geometric dimension of diamond saw blade mainly focuses on the outer diameter and aperture. In the actual inspection, the hole diameter of the saw blade is generally inspected by the internal micrometer, while the inspection of the saw blade matrix and the saw tooth boundary dimension is inspected by the steel tape, steel ruler and vernier caliper. The main content of the inspection is to check the accuracy of the hole diameter, and whether there is scratch and unevenness of the saw blade substrate itself.
3. End face and radial runout inspection
For a qualified diamond saw blade, its own mandrel radial runout shall not be greater than 0.01mm. In the actual inspection, for the end face and radial run out of diamond saw blade, the first choice is the circular run out instrument. When detecting the end face and radial run out of the saw blade, the flange shall be used to fix the saw blade on the mandrel, the dial indicator contact shall be placed at the outer diameter of the saw blade and the distance between the side of the base and the bottom of the groove respectively, and the saw blade shall be rotated slowly,read out the value on the dial indicator, which is the radial and end circular runout value of the saw blade. Of course, in addition to the end face and radial run out of the diamond saw blade itself, the flange used to fix the saw blade also needs to be tested. Among them, the end face run out tolerance of flange plate shall not be greater than 1 / 10 of the end face run out tolerance value of the measured saw blade, and its diameter shall not be greater than 1 / 3 of the diameter of the measured saw blade.
4. Welding strength inspection
For a diamond saw blade, the matrix is the foundation, and the saw tooth determines the cutting performance of the saw blade. Saw blade is not easy to use, saw performance is very important. As the welding strength inspection that can affect the saw tooth performance, it is the key to ensure the saw tooth performance. Because when the saw blade is used, if the saw tooth is combined with the substrate,The strength is not enough. It is very likely that the sawtooth fracture will be thrown out and hurt people. Therefore, before any diamond saw blade leaves the factory, it is necessary to check the welding strength, and the inspection standard has been formulated as a national standard. At present, the most commonly used method for diamond welding strength inspection is ultrasonic inspection.
