Production Process Flow of Straight Coolant Hole Carbide Rods

Creating straight coolant hole carbide rods is a meticulous process. Here’s how it works:

  1. Powder Preparation: Tungsten carbide powder is blended with cobalt and other binders.
  2. Mixing: The mixture is uniformly combined to ensure consistent properties.
  3. Compacting: The powder is pressed into rod shapes with channels for coolant holes.
  4. Pre-Sintering: The rods are heated at lower temperatures to strengthen their structure before final sintering.
  5. Sintering: Final sintering at high temperatures creates a dense, robust product.
  6. Cooling: Slow cooling ensures stability and minimizes internal stresses.
  7. Finishing: Includes grinding, polishing, and quality checks to meet precision standards.
