Basics
A surface grinder is a device that is used to accurately and intricately remove unneeded layers from a surface in an effort to smooth the target layer. The reason that a surface grinder is used is that it provides a great level of accuracy and detail that is sometimes difficult to achieve by hand. The use of a surface grinder is concentrated in heavy industry, especially in the automotive industry. Surface grinders are used on various types of metal and woods. The surface being worked on is directly related to the blade being used as they are specialized for different surfaces. This is a better option than trying to grind a surface by hand as it is less time consuming.
The amount of time it takes to grind a surface depends on the skill of the user and the surface being ground. The best safety guideline with a surface grinder is to take your time. Most accidents happen by using the wrong blade with the wrong material or running the blade on the grinder faster than the speed it was meant to run at. A surface grinder can be used to prepare surfaces such as floors and sheet metal for cars.
How It Works
The typical surface grinder has a table that is capable of moving forward and backward as well as side to side. When moving side to side, the table uses hydraulics to move. The machine also has a grinding wheel that rotates and has an adjustable height. The grinding wheel is generally made of diamond, aluminum oxide, silicon carbide or cubic boron nitride. The majority of surface grinders used in the modern era are at least partially automated. The work material is held on the table of a magnetic chuck and sometimes an electro-magnetic chuck depending on the specific machine.
What a Surface Grinder Does To Material
A surface grinder produces a high level of heat which will create stress on the material. After being run through a surface grinder, a material will be more apt to breakage or fracture than before it was run through the machine. A material can also lose its magnetic properties if its temperature is raised too high.
