The first step in a grinding machine project is the selection of a roughing tool, which is an electrically active tool that rotates at a high torque and has the ability to work over a wide range of temperatures. These tools are often referred to as roughing tools and can be made of numerous different materials such as stone, glass, plastic, ceramic and porcelain. They can be powered electrically or by means of a gear-driven mechanism. In electrical roughing, the electrical current that passes through the tooling area causes the rough surface to vibrate, creating the wear pattern that allows the tool to grind into the material. In the other case, the mechanical power of the tool creates the pressure that causes the metal to grind into a rough surface.
The two most common types of surface grinding are hydraulic and mechanical. Hydraulic is also known as pulsating or centrifugal grinding, and its most well-known application is the production of coin seals from stamped coins. Mechanical grinding uses a sliding wheel to create a flat surface, often in thin metal, that can then be honed. This process is often used in conjunction with a cutting wheel to grind into very dense and hard metal.
A third type of surface grinder is the diamond grinding wheel. This consists of a fixed diamond disc that rotates at a low-rate and is similar to the hydraulic wheel. Diamond grinding wheels can be used to quickly grind soft, light, or infrequently-used materials such as brass or copper. Many diamond grinding wheels are available in workpiece material such as wood, ceramic tile, granite, marble and even computer chips.
Magnetic Chuck: A third type of surface grinder involves the use of a magnetic chuck. A magnetic chuck has a metal disc attached to the outside of a metal workpiece. This disc forces a ground material against the workpiece surface, making it into either an original shape or a customized shape to match the workpiece. A unique advantage of a magnetic chuck is that it provides a continuous work flow and significantly reduces chatter and burrs. Some of the most common applications for these types of surface grinders are drilling, polishing, and paper grinding.
In addition to the three types of grinders mentioned above, there are many other types of grinders available. Some grinders are powered by electric, and others are powered by gas or water. The amount of power a grinder needs to perform its intended task depends upon the type of work that it is intended to do, and its environment. An electric surface grinder will require little to no maintenance and can grind heavy material quickly and effectively.
