About TCT Saw Blade Production Process Testing

1. Hardness change detection of alloy saw blade after welding teeth. Three kinds of temperature are selected in the process of welding saw blade teeth. The hardness matrix remains unchanged when the base tooth holder is heated at 650 degrees. The hardness increases only 3-5 degrees at 750 degrees. When the temperature is 800 degrees, the hardness has reached 55-58 degrees, so the matrix teeth are broken during cutting. The volume of generator with different tooth shape or thickness of saw blade is also very important.

2. Alloy saw blade side front Angle and side back Angle detection. Many people choose to rely on the table when detecting the side front Angle. When detecting the side front Angle, the alloy knife back groove Angle changes, or the alloy length changes. Add the matrix deformation, or is still not in the central park, use point surface contact to measure the side Angle, it is only a approximate reference value, not absolute value. The rear side Angle is affected by the diameter of grinding wheel A and B sides. And the five different changes of grinding center line, the essence is only a reference value, rigorous detection still needs to be the most accurate video camera.

3, saw blade welding tooth deformation detection. Material thermal stress or cold tension will change in the process of thermal change. It is mainly caused by the material, temperature, cooling time, workpiece thickness heating area and other factors. According to the matrix in the cold state of measurement, due to the inevitable factors of the next process to bring changes to the welding teeth, at this time, according to the above recorded data, we do another test along the record mark in accordance with the above 6 methods, depending on the amount of deformation, the analysis can also see the harm of the welding teeth to the matrix deformation.

4, alloy saw blade diameter jump detection. There are three kinds of strong jump state, the first kind of 180 degrees of eccentric high and low, the second kind of left high right bottom or right high left bottom, the third kind of high and low uneven. The first kind of hole fit is too poor, the matrix aperture is too large, resulting in 180° deviated circle height; Second, as long as the matrix is not the center of the grinding tool, the left and right grinding head is not grinding on a center; The third kind of mechanical accuracy is not reliable grinding wheel quality or grinding wheel uneven arc.

5, alloy saw blade end jump detection. The main reasons for end jump of alloy saw blade are elasticity and plastic deformation of matrix. The mechanical clamp is not uniform, there may be a bounce tooth claw coordinate is not stable. Detection of grinding wheel quality or uneven concave and convex surface and arc and other factors does not allow micrometer measurement due to matrix wave or pot type state.
