Which grinding wheel can grind SKD61 material hardened to 50 degrees?

When it comes to grinding hardened materials like SKD61, selecting the proper grinding wheel becomes crucial for achieving desired results. The hardness level of 50 degrees adds an additional challenge to the process. In this article, we will explore the various grinding wheels available and determine which one is best suited for this specific task.

SKD61 is a popular tool steel known for its high toughness, heat resistance, and excellent wear resistance. However, these properties also make it challenging to grind. Grinding hardened SKD61 requires a grinding wheel that can withstand the high forces and temperatures generated during the process while providing efficient material removal.

One of the most commonly used grinding wheels for grinding hardened materials is the CBN (Cubic Boron Nitride) wheel. CBN is a superabrasive material known for its exceptional hardness and heat resistance. It offers superior cutting ability and durability, making it suitable for grinding hardened steels like SKD61. The CBN wheel can maintain its sharpness and does not require frequent dressing, resulting in improved productivity and cost-effectiveness.

Another option worth considering is the diamond grinding wheel. Diamond is the hardest known material and offers excellent cutting ability on hard materials like SKD61. Diamond grinding wheels can effectively grind hardened steels with precision and efficiency. However, they tend to be more expensive than other options.

In addition to the choice of abrasive material, the structure and bond of the grinding wheel also play a crucial role in grinding hardened SKD61 to 50 degrees. The structure refers to the arrangement and spacing of the abrasive particles on the wheel surface, while the bond is the material that holds the abrasive particles together.

For grinding hardened SKD61 at a hardness of 50 degrees, a fine-grit grinding wheel with a dense structure and strong bond is recommended. This combination allows for efficient material removal without excessive heat generation. The dense structure ensures that the abrasive particles are closely packed, providing a larger number of cutting edges, while the strong bond prevents premature grain breakage or glazing.

It is essential to consider the operating parameters such as cutting speed, feed rate, and coolant usage while grinding hardened SKD61. These parameters must be optimized to avoid overheating, excessive wheel wear, or surface damage. Consultation with experts or referring to the manufacturer’s recommendations can be helpful in determining the appropriate operating parameters for grinding SKD61 to 50 degrees of hardness.

In conclusion, when grinding hardened SKD61 material to a hardness of 50 degrees, choosing the right grinding wheel becomes vital. The CBN and diamond grinding wheels are two excellent options due to their exceptional hardness, heat resistance, and cutting ability. Additionally, using a fine-grit wheel with a dense structure and strong bond ensures efficient material removal without compromising the integrity of the grinding wheel. By considering these factors and optimizing the operating parameters, one can achieve precise and efficient grinding results on SKD61 material hardened to 50 degrees.
