Blanchard grinding and precision grinding

When we need to make the material into the required finish and size, we use a grinding process. There is a wide range of smoothing methods, so it's important to choose the right process for your intended application. Failure to do so may jeopardize the quality and results of the project. Two common methods are Blanchard and precision grinding. Read on to understand the difference between the two smoothing methods so that you can better choose the process that meets your manufacturing application needs.

Blanchard grinding

Blanchard grinding is a process commonly referred to as Rotating surface grinding. It was developed in the early 20th century by a company called Blanchard Machine Company. The most common application for smooth surface rotation is large surface cutting. For this application, it is better than exact smoothing because it is simpler. It is also preferred because it leaves a distinguishable surface modification mark. They are considered to be aesthetically appealing to some people.

Grinding large ferrous metals [IronMaterials using this processing method are usually held in place using a magnet while smoothing. On the other hand, as long as an alternative locking device is used, it is still suitable for non-ferrous metals that do not contain iron or other traces of iron. That is because the non-ferrous materials are not magnetic.

Examples of Blanchard grinding applications:

• 
  
  
  
  Stamping


• 
  
  
  
  casting


• 
  
  
  
  Forgings


• 
  
  
  
  Segmented sheet stock


• 
  
  
  
  Mold

Precision grinding

If you have a small surface to use, precision grinding is the right process. This method is mainly used for materials with a small surface area, requiring a particularly flat surface treatment or strict parallelism. There are other forms of precision smoothing, such as horizontal spindle surface grinding, which uses a rotating grinding wheel that is in contact with the surface of the material. Cylindrical grinding is another precision smoothing that is very similar to horizontal spindle surface grinding. The main difference is that it is used for circular surface areas. Other types include centerless grinding, peristaltic feed grinding and inner diameter grinding.

Abrasives commonly used for precision grinding include alumina, silicon carbide and zirconia alumina. Sometimes lubricants are used to regulate high temperatures during the grinding process. Common applications for precision smoothing include machine parts, castings, stampings, shafts, bushings, pistons, cylinders, molds and molds.
