In this article, our machine tool experts discuss the different types of bench grinders available and their common uses. Best of all, we recommend one specific model that we believe is the best option for most machine shops, below.
Uses for Bench Grinders
There are many different uses for bench grinders in machine shops. They can be used to sharpen tools, remove rust from metal pieces, and polish surfaces.
Bench grinders are also commonly used to grind down welds to create a smooth finish. The most common use for a bench grinder is sharpening tools.
When sharpening chisels or other cutting tools, it is important to use a consistent angle and pressure to ensure a clean, sharp edge. The best way to do this is by using a jig or guide that attaches to the bench grinder and holds the tool at the correct angle.
Bench Grinders Remove Rust From Metal Pieces
This can be done by using a wire brush attachment on the grinder. The wire brush will quickly remove rust and leave a smooth surface behind.
Bench grinders can also be used to polish surfaces. This is often done by using a buffing wheel attachment.
Buffing wheels come in different sizes and shapes, so it is important to choose one that is appropriate for the task at hand. Buffing wheels can be used to remove scratches from metal surfaces or to polishing wood to a high shine.
Best Grinder Tools
No matter what the application, bench grinders are an essential tool for any machine shop. By understanding the different types of bench grinders and their common uses, you can select the right one for your needs.
Palmgren Combination Bench & Belt Grinder
For example, this Palmgren Combination Bench & Belt Grinder has a 8″ disc and a 2-inch-wide belt. This makes it a versatile choice for grinding, sanding, and finishing operations.
Disc grinders are the most common type of bench grinder. They are typically used for general grinding tasks, such as shaping or sharpening metal objects.
Belt grinders are less common, but they offer more versatility. As the name implies, they use a belt instead of a disc. This design can be used for tasks such as deburring, polishing, and stock removal.
