What is surface grinding?
Surface grinding can be defined as the process of providing a smooth finish to the topmost layer of a flat surface. The process can be conducted with the help of surface grinder machines which are abrasive machines. This kind of machine features a grinding wheel which is covered with rough abrasive particles and attached to a spindle. When this wheel is spun at a high speed, the chips present on the surface of the material which needs to be given a smooth finish are cut off, thereby making the surface flat and smooth. This is one of the most common grinding operations that are performed and is classified as a finishing process.
Why Use Surface Grinding?
Surface grinding can be conducted for two reasons one, to give the work piece a more refined look and secondly, for serving a functional purpose. It can be used on metals and wooden surfaces alike in order to bring about the polished and smooth look. Depending on the surface to be smoothened, a suitable type of surface grinder can be picked. It goes without saying that metals would require grinding with a highly abrasive material that have several cutting niches embedded on its surface which surfaces such as wood do not require a very abrasive wheel.
Types of Surface Grinder
As far as basic surface grinders are concerned, there are two categories of such tools the planner kind of surface grinder and the rotary type. In case of the former, the grinding wheel does not move at all but it is the worktable which moves back and forth. This movement can be facilitated with the help of a hydraulic drive system or it can be done manually, although the former is more convenient.
In case of the rotary type of surface grinding machine, both the worktable as well as the grinding wheel rotates. This kind of grinder is generally used for the purpose of grinding precision machine parts before they are fitted in their respective positions inside a machine. Irrespective of which surface grinder you use, i.e. the planner type or the rotary type, you can rest assured that there are very less chances of mishaps taking place because the safety hazards are dealt with very well in case of both the types of surface grinders.
What Next After Surface Grinding?
One of the most common mistakes that people make after engaging in surface grinding is that they do not follow it up with a thorough cleaning of the work station. While the cleaning part may make the work station look tidier, the primary reason why you should clean up after such a process is to avoid mishaps. Many a times, the debris like saw dust in case of wood and metal bits or shavings in case of metals can cause serious injury to people walking around barefoot. Therefore, after each operation, clean up the work area and get rid of all the debris. Also, check your grinder for any remaining debris that might be blocking its air vents or causing major problems to these parts.
