Key Factors to Choosing a Grinding Wheel

There are several different types of grinding wheels, for example, 3M scotch brite 7447 all of which come in a variety of grit sizes and are held together by various additives and bonding chemicals. How can we know which one to choose? Numerous abrasive instruments and tools with properly specified settings are required for a wide range of industrial grinding operations and needs. We’ve all used grinding wheels in our work, but the majority of us have no understanding of why we use them or whether the wheel we’re using is appropriate for the job. As a result, we must make a careful selection of grinding wheels with qualities that fulfill the criteria in order to be successful.

Type of the Abrasive Material

When selecting a grinding wheel, the type of workpiece material and hardness are the initial considerations. Is it easy or tough to crush the material? The appropriate abrasive kind, grain feature, abrasives size, and bonding type for the grinding process are all determined by how easy it is to grind. Once we’ve determined which grain type to start with, we can look at the material’s grind ability. If the material is easy to grind, we can choose to use a tough/durable grain.

Speed of the Wheel

Another crucial factor to consider is the wheel speed. We must consider the wheel’s operating speed while considering surface speed. The wheel speed determines which bond type is suitable for the intended speed and whether a special high-speed bond is necessary. At slower wheel speeds, the force per abrasive particle is greater, causing the grain and/or bond to break down quicker.

Horsepower of the Machine

The horsepower of the grinding machine must be evaluated in order to calculate the bonding grade or the toughness of the wheel. When a machine has more horsepower available at the spindle, a tougher wheel grade should be employed. When the machine has little power or is underpowered at the spindle, we may not be able to generate enough force to break down the wheel as needed, resulting in grain lessening, burns, and other surface defects.

Area of Contact

The surface area is tied to pressure in a hydraulic system when considering the contact between the workpiece and the wheel (or the area of contact), and this factor evaluates how the effort exerted to generate a chip will be divided around the grinding zone. The force applied to the work by a wheel is spread throughout the grind zone’s cutting points. The larger the contact area, the lower the force per gain. Similarly, the smaller the area, the larger the power per grain. The best machine tool supply company in the UAE can help you choose the most suitable grinding wheel based on your necessity.
