The scraped trowel is ground into a wooden mold manual shovel, and the effect is obvious. Use a file with a thicker edge and a thicker blade (the file is too fine, the hardness is too high, it is easy to be brittle during grinding and use), the size of the old file is 200mm × 35mm × (5 ~ 6) mm, the old file will be selected One side depends on one side of the Grinding Wheel, and a groove is made by grinding the diameter of the grinding wheel. The rear end of the groove is about 1.5 to 2 mm deep, and the front end is dark red 0.1 to 0.2 mm. The side of the grinding groove is used as the back side, and then the razor blade is placed on the sand.
1. Sintered diamond saw blade: It is divided into two types: cold press sintering and hot press sintering, which are formed by pressing and sintering.
1.Continuous edge saw blade: continuous sawtooth diamond saw blade, generally made by sintering method, commonly used bronze binder
Introduction of diamond saw blade
Diamond saw blade is a kind of cutting tool, which is widely used in the processing of hard and brittle materials such as stone and ceramics. Diamond saw blade is mainly composed of two parts; the base body and the Cutter Head. It is the part that cuts during use. The cutter head will be continuously consumed during use, but the substrate will not. The reason why the cutter head can cut is because it contains diamond, which is currently the hardest substance. , it frictionally cuts the processed object in the cutter head. The diamond particles are wrapped in metal inside the cutter head.
Manufacturing Process Classification
1. Sintered diamond saw blade: It is divided into two types: cold press sintering and hot press sintering, which are formed by pressing and sintering.
2. Welding diamond saw blades: divided into two types: high-frequency welding and laser welding. High-frequency welding welds the cutter head and the substrate together through high-temperature melting media, and laser welding uses high-temperature laser beams to melt the contact edge of the cutter head and the substrate to form metallurgy combine
3. Electroplated diamond saw blade: the blade powder is attached to the substrate by electroplating.
Appearance classification:
1.Continuous edge saw blade: continuous sawtooth diamond saw blade, generally made by sintering method, commonly used bronze binder
2. Segment head type saw blade: the saw teeth are broken, the cutting speed is fast, suitable for both dry and wet cutting methods
3. Turbine-type saw blade: Combining the advantages of 1 and 2 above, the saw teeth continuously present a turbine-like uniform convexity, which improves the cutting speed and increases the service life.
