Normal Flat Long Life Diamond Cutter Diamond It is a tool material with hard processing texture, so it is more rigorous for the processing technology. Diamond bit is the most important part of the tool, which is equivalent to a sharp edge of the tool.



1. Weighing the metal powder and diamond in proportion according to the formula;

2. The mixing time of metal powder and synthetic diamond is more than 8h;

3. Install the mixed material into the graphite mold. When loading, the metal powder without diamond spoon should be loaded first, and then the mixed diamond and binder powder should be loaded after compaction;

4. Pressing the mold in the sintering furnace for pressure and heating, sintering and heat preservation;

5. Grinding after the hot pressing cutter head is peeled off from the grinding tool, the edges and corners shall be polished to make the edge smooth and easy to weld.

If it is used for diamond saw blade, it needs to be welded to the substrate of diamond saw blade through welding process. The common welding methods include laser welding, high frequency welding and other welding methods.

1. According to the production requirements, check the inner and outer diameter, thickness and tooth number of the base, and check the specification, quantity and radian of the segments. Then the chamfer of the outer circle of the substrate is ground on the dressing equipment. Clean the welding surface of substrate and segment with acetone, and apply brazing flux.



2. According to the specification of saw blade in the construction requirements, the welding blade shall be selected, and the width of the welding blade is generally 0.0 larger than the base thickness. The thickness of welding blade is 0.25-0.30 mm when welding the saw blade with a diameter of more than 1500 mm, and 0.15-0.25 mm for the saw blade with a diameter of less than 1500 mm.

3. Install the substrate, adjust the position, tighten the fixing screws, put on the cooling splint, adjust the segment pushing device and segment clamp, adjust the welding temperature, heat preservation and cooling time according to the process requirements, and then weld.



4. Welding saw blade with Boreway High frequency induction heating machine china supplier,When welding a segment, rotate the substrate 180 ℃ so as to avoid annealing or local deformation caused by overheating of the substrate.

5. When welding the row saw, weld the cutter head one by one on the base teeth of the saw blade according to the tooth layout diagram.

6. After welding, it is necessary to check the balance, glossiness, connection tightness between the blade and the substrate of each saw blade to ensure that each product delivered to the customer is perfect and suitable.
