Surface grinding is very often used to create a smooth surface on rough surfaces. It’s a popular abrasive grinding procedure where a rotating wheel covered with fine abrasive particles is used to grind metal or non-metal materials from a workpiece. The abrasives act as a hard coating against the surface of the material. This results in a flat surface and the metal or non-metal is ground smooth.
There are three types of surfaces used on these grinding tools: high speed, medium speed and low speed. High speed grinder is designed for working with heavier materials, such as metals and ceramics, while the medium speed grinding wheels are designed for working with lighter materials. High speed and medium-speed grinder can be used on smooth and rough surfaces, as long as they are of high quality and durability. Low speed grinding wheels are often used for abrasive work and are less expensive than the other two types.
Although the basic function of the grinding wheel remains the same, the variations in its design and purpose can greatly affect the work performed. For instance, coarse abrasives are commonly used on rough surfaces; but, high speed grinder grinds metals with fine abrasives, while medium speed grinder is designed for fine work with the use of medium abrasives. Some grinding wheels have an internal safety valve that automatically shuts off and stops the grinder when the blade reaches its maximum speed.
Grinding wheels can either be self-cleaning, or you can get them cleaned by hand using a wet cloth or toothbrush. However, if you are cleaning a surface grinder for the first time, you should always remember to wear protective eye protection to avoid injury.
If you want a good idea of how much work is accomplished with your surface grinder, you should measure the size of the blades. Smaller blades will grind faster and harder and can perform better on a rough surface, while the larger ones will grind harder but not be able to reach as far. As a general rule of thumb, the larger the blades, the bigger the area you can work with and the less time you need to grind each square inch of your surface.
Grinding wheels are available for both electric and manual models. If you buy an electric model, make sure that it’s easy to use and install, especially if you plan to store it in a workshop. If you buy a manual grinder, make sure to read and follow the manual thoroughly before use.
