According to the tooth material of the hole saw, it can be divided into bimetal hole saw, namely hole saw, cemented carbide hole saw, diamond hole saw and tungsten carbide hole saw. After having a tungsten carbide hole saw, the most annoying thing should be the tungsten removal treatment method of the tungsten carbide hole saw workpiece. Next, let us talk about the method of removing tungsten with Tungsten carbide hole saws .

1. Cleaning of tungsten carbide workpieces First use cleaning fluid to clean tungsten carbide workpieces to remove oil stains on the surface of tungsten carbide workpieces, and then rinse the tungsten carbide workpieces with water.
2. Clamp the tungsten carbide workpiece so that the tungsten carbide workpiece can be rotatably fixed on both ends of the electrolytic cell.
3. To prepare the electrolyte of the electrolytic cell, please add one ton of water to the electrolytic cell, then add 50kg Na2CO3UOkg potassium sodium tartrate and stir to dissolve it.
4. In addition to coating, the tungsten carbide workpiece is also used as an anode, and the stainless steel plate is used as a cathode. Turn on the power and make the tungsten carbide workpiece rotate in the electrolytic cell to make it completely contact with the electrolyte, so that the electrolysis reaction occurs. The current density is controlled at (200300)×DL(A^m2), the pH of the electrolyte is controlled at 10-13, the temperature is controlled at 20-80°C, and the electrolysis reaction time is 12 hours.
5. Clean and take out the tungsten carbide workpiece after electrolysis, and rinse its surface with clean water.

The method is a tungsten removal treatment method for tungsten carbide workpieces, and the method is harmless, non-toxic, environmentally friendly and low in cost. It includes the following process steps: cleaning the tungsten carbide workpiece → clamping → preparing the electrolyte → removing the coating → cleaning these steps.

Of course, the tungsten carbide hole opener also has other tungsten removal treatment methods, but this method is relatively safer and more environmentally friendly. Like tungsten carbide hole saws, various problems can arise when using Diamond cup grinding wheel . The most important thing is the solution and the process, and the experience gained from it. This is the point.
