What Are the Different Types of grinders?

Surface grinder is used to create a very smooth finish on various flat surfaces. It’s a widely applied rough machining method where a rotating diamond-tipped wheel is employed to cut chips of nonmetallic or metallic material from a workpiece, creating a flat face of it smoothly or gently. This is the most frequently used type of abrasive grinding in abrasive grinders and power grinders because it has the ability to perform extremely heavy duty grinding without wear and tear or clogging. You can use a grit size in this grinder ranging from very coarse up to soft. You can use different types of grinding wheel such as: wet grind, dry grind, pulsating grind, wire wheel, and ultra coarse grit in this grinder. Although the concept of grinding fine metal using a grinding wheel dates back to Macedonian period, it wasn’t until the 20th century that it became popular and efficient enough to use in various industries.

There are many reasons why you would use a surface grinder in your abrasive or finishing process. Some examples of using it in machining are: sanding of wood, finishing sanding of ceramic tiles, finishing sanding of stainless steel, finishing sanding of aluminum, copper, laminate floor sanding, burring and honing of steel, chrome and brass pitting, abrasive polishing and many more. Since it’s very convenient to operate and simple to start with, many companies nowadays are adopting the use of this machine in their various machineries. This has enabled them to decrease costs of operations and improve productivity as well.

A simple way in which you can use a surface grinder in your work is by manually grinding a workpiece to a rough finish or smoothing a workpiece after machining. This works in a similar manner as an electric orbital polisher except that it also grinds workpieces to a rough finish, a polishing finish, or a grit-free finish. One of the best advantages of using a magnetic chuck along with a grinding wheel is the ease of use. You simply switch on the grinding wheel, stop when the workpiece is at the required workable height and press the magnetic chuck into the work.

This is a very simple operation and does not take much time, effort or force from your part. In fact, the magnetic chuck and the polishing wheel can be used together in any finishing process. If you are using a very coarse abrasive wheel, such as an alumina abrasive, you will find it easier to use the magnetic grinding and polishing together than if you were working with a coarse and thin abrasive wheel. The polishing action of the grinding stone against the rough surface of the work piece also ensures that the work will have a flat, smooth finish. This flat finish is important because it reduces the need for excessive abrasives and finishes.

Magnetized surface grinders are available in a variety of sizes and types. Smaller handheld models are ideal for performing light polishing and grinding actions, while larger and heavier versions are designed to be used in large surface grinders. The choice of size and type of the grinding wheel also depends on your needs. For example, a small handheld surface grinder can be used to perform light, fine finishing operations and is great for getting into tight places. Larger wheels are better suited for heavy duty work, however they are also more expensive and more difficult to operate.

There are many advantages of using a surface grinder along with a grinding wheel. A polishing surface may be necessary to obtain the flat finish you desire. Also, you might need to use a small polishing wheel to sand down an undercoat of paint in order to prepare the work surface for painting. In cases such as these, a surface grinder coupled with a large grinding wheel is often the best solution. Overall, the selection of this equipment depends upon your current needs and the nature of your work.
