When using tungsten carbide hole saws, it is often found that Tungsten carbide hole saws have the phenomenon of removing tungsten. Therefore, in view of this phenomenon, let us see if there is a better way to solve this problem.
(1) Cleaning of tungsten carbide workpiece Firstly, clean the tungsten carbide workpiece with cleaning fluid to remove the oil on the surface of the tungsten carbide workpiece, and then rinse the tungsten carbide workpiece with water.
(2) Clamping: Clamp the tungsten carbide workpiece so that the tungsten carbide workpiece can be rotatably fixed on both ends of the electrolytic cell.
(3) Prepare the electrolyte, add one ton of water to the electrolyzer, then add 50kg Na2CO3, UOkg potassium sodium tartrate, stir to dissolve.
(4) To remove the coating, please use a tungsten carbide workpiece as an anode and a stainless steel sheet as a cathode. Turn on the power supply, make the tungsten carbide workpiece rotate in the electrolytic cell, make complete contact with the electrolyte, and electrolysis reaction occurs. The current density is controlled at (200 300) * DL (A·!!! 2), 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. By adopting the above technical scheme, the tungsten carbide workpiece is removed by an electrochemical method. The electrolyte was prepared with Na 2 CO 3, potassium sodium tartrate and water. The electrolyte is non-toxic, environmentally friendly, harmless to the human body, and can be recycled. Secondly, the electrolyte only needs to be discharged once every two years, and the cost is low.
However, no matter which method is used, it must be used with care. After use, you must pay attention to the maintenance of tungsten carbide hole openers, Diamond cup grinding wheel and other workpieces to make the workpieces longer service life. www.jeejatools.com
