All About Grinding Wheels
Surface grinder is an abrasive grinding tool which can be used for various purposes. It is basically used to make a smooth surface on flat surfaces without leaving any rough edges. It is a popular abrasive machining technique in which a rotating wheel covered with rough particles grinds chips of metal or other non-metallic material from an object, forming a smooth or flat face of it. Grinding wheels are of different types. They are available in different materials such as bronze, steel, iron etc.
Grinding wheels are usually mounted on the workbench with the surface of the work surface facing towards it. This makes it possible for the grinding wheel to move along the work surface. There are many types of grinding wheels and most of them are of the same size and shape. They are commonly used in the aerospace industry as a part of the machining tools. These wheels also have a number of features in common. The most important feature is that they rotate at very high speeds and so they can move around very quickly. They are used to grind down material of different shapes, sizes and materials such as stainless steel, aluminium, bronze and so forth.
In order to control the speed of the grinding wheel, there is a cam fixed on the surface of the tool that has two axes. The one that is perpendicular to the working surface rotates at high speed while the one that is parallel to the working surface rotates at low speed. As these two axes are opposite each other in polarity, the rotating wheel turns around to the side of the working surface in a clockwise direction.
Another important feature of the surface grinder is that it uses special lubricants to protect the rotating wheel. These lubricants can be of different viscosities and in different combinations. This lubricant has a very important function to prevent wear of the moving parts. The lubricant also helps in the formation of micro fractures in the moving parts and also protects them against wear.
While using the surface grinder, the working surface must not be allowed to become damp or slippery. This can lead to the grinding wheel coming off the working surface or even the surface. If the working surface becomes slippery, the grinding wheel may slip off the rotating wheel on its own. This can result in the working surface getting damaged. and it will need to be replaced with a new one.
It has been seen that surface grinder, especially those used in aerospace industry, are much more powerful and accurate than other grinding tools because of their speed. They can be made of steel and are also equipped with several settings for grinding, polishing and honing.
