The Fundamental Principles of Surface Grinding

February 15, 2021

Parts and products that are made from different materials undergo numerous processes to alter and improve their properties. Some of the processes are intended to make their overall properties to be stronger and more resistant to elements. Others, alternatively, are done to change their surfaces.

One process that a lot of parts and products undergo is surface grinding. It is a finishing process that is designed to provide a smooth finish on the surfaces of metals and other materials. Surface grinding maximises an abrasive machining process through a spinning wheel that is covered with rough particles. The spinning wheel is usually attached to surface grinders.

The Process of Surface Grinding

Surface grinding is known to be one of the most common grinding operations out there. And for its entire process, it normally utilises a surface grinder that is comprised of a spinning wheel, a special type of clamp for holding the workpiece, and a reciprocating or rotary table. The spinning wheel is usually made of a composite material that has some rough or coarse aggregate. The special type of clamp, which is also known as the chuck, can hold the workpiece in place while it undergoes the surface grinding process. An electromagnet can also be used in holding a workpiece that cannot be clamped down.

As the workpiece is set to the reciprocating or rotary table, the height of the surface grinder components is adjusted so they can effectively carry out the surface grinding process. Once the spinning wheel acquires its intended grinding speed, the table will then start to move so that the wheel can start the grinding process. An even grinding of a workpiece is possible as the work bed can move in any directions.

Benefits of Surface Grinding

The process of surface grinding is carried out to different parts and products as it can provide many benefits to different industries. For one, surface grinding operations can easily produce metal products that possess high-quality smooth finish. These operations can also come up with metal parts and products that have highly accurate dimensions. Surface grinders are capable of processing delicate metal parts and products thanks to their accuracy of around 0.0001 inches.

Surface grinding can likewise benefit many industries as it can be performed on a wide array of materials. Abrasive or hard materials can be processed with surface grinding. Both metallic and non-metallic products can also be subjected under the surface grinding process.

Surface Grinding Limitations

The relationship between the spinning or grinding wheel and the workpiece material can determine the effectiveness of the surface grinding process. Some materials such as cast irons and steels can be easily processed by surface grinders. Other materials like aluminium, brass, and plastic, however, can become too hot once they undergo the surface grinding operation.

Another thing to consider in surface grinding operations is the time required to carry them out. The initial setup of the components can be tedious, but once everything is in place, the surface grinding process can truly provide great benefits to industries and businesses.
