Exploring Abrasives: Understanding Grinding Wheels

What is an abrasive material commonly used in grinding wheels?

A) Aluminium oxide
B) Silicon carbide
C) Diamond
D) Corundum

Answer:

The correct answer is (D). The grinding wheel marked with "c" is made with the abrasive corundum.

When it comes to grinding wheels, the choice of abrasive material plays a crucial role in determining the cutting ability and performance of the wheel. In this case, a grinding wheel marked with "c" indicates that it is made with corundum as the abrasive.

Corundum is a crystalline form of aluminum oxide (Al2O3) known for its hardness and toughness. It is commonly used in grinding wheels for its effectiveness in grinding softer materials. Corundum is suitable for general-purpose grinding applications and provides reliable performance.

Understanding the abrasive material used in a grinding wheel is essential for selecting the right wheel for specific applications. Different abrasives have varying characteristics that make them suitable for different types of grinding tasks. By choosing the appropriate abrasive, you can achieve optimal results and ensure the efficiency of your grinding operations.
