To grind tungsten carbide use a diamond grinding wheel. Tungsten carbide is widely used for its hardness, wear resistance, and high-temperature resistance. However, these characteristics also make its machining quite challenging. This article will discuss which grinding wheel should be chosen for grinding tungsten carbide and provide some practical advice.

Diamond grinding wheel: the optimal choice for tungsten carbide grinding.

The diamond grinding wheel is the preferred choice for grinding high-hardness materials like tungsten carbide, due to its high efficiency, precision, and longevity. Although more expensive and with a complex manufacturing process, its advantages in dealing with tungsten carbide are unmatched.

Selection of grinding wheel specifications.

Choosing the right grinding wheel specifications is crucial. It is necessary to consider the required grinding size and surface requirements while avoiding overly hard wheels that could alter the cutting surface. Also, different grit sizes should be used for rough and fine machining.

Precautions.

  1. Inspect the grinding wheel before use and do not use if there are any defects.
  2. Select the grinding wheel based on the hardness, properties, and shape of the material being machined.
  3. Strictly follow the procedures for installing and checking the dynamic balance of the grinding wheel.
  4. Adhere to operating procedures and pay attention to any abnormal conditions of the grinding wheel.

Two needs for tungsten carbide grinding.

  • Form Grinding: Requires a grinding wheel with good grinding force and shape retention. Here, resin or ceramic bond diamond wheels are recommended.
  • Improving Edge Brightness: Elastic diamond wheels are needed to remove tool marks, reduce cutting resistance, and increase the lifespan of tungsten carbide tools.

Grinding wheel selection for tungsten carbide.

  • Wheel Hardness: Should match the hardness of tungsten carbide. Diamond wheels, suitable for high-hardness materials, are recommended.
  • Grain Size of the Wheel: It is advised to choose a grit size between 200 to 600 to ensure the removal of burrs and smoothing of the surface.
  • Grinding Precautions: Include cleaning before grinding, cooling of the wheel and tungsten carbide, and controlling grinding speed and direction.

When grinding tungsten carbide, selecting the right grinding wheel is crucial. Diamond wheels offer high efficiency, but the right specifications and materials must be chosen based on the specific grinding needs and the characteristics of the workpiece.
