Abrasive Processes - ScienceDirect

01/01/2015  Grinding is a complex process. As the abrasive particles scratch the surface of the material several different microprocesses come into play (flow, cracking, fracture). The result depends on a number of factors, including the shape, force and the velocity of the particles, the humidity of the environment, the hardness and the crack resistance of the material and the distribution of

Surface grinding - Wikipedia

Surface grinding is the most common of the grinding operations. It is a finishing process that uses a rotating abrasive wheel to smooth the flat surface of metallic or nonmetallic materials to give them a more refined look by removing the oxide layer and impurities on work piece surfaces. This will also attain a desired surface for a functional purpose.

Gear Grinding Process - Hindustan Abrasives

What is gear grinding? Gear teeth can be created entirely by grinding, completely by cutting, or by first cutting and then grinding to the expected dimensions. Normally, gear grinding process is done after gear has been cut and heat-treated to high hardness. Grinding is essential for parts above 350 HB (38 HRC) where cutting becomes very hard. Teeth produced by grinding are normally those of definite pitch,

What Is A Surface Grinder - West Midland Grinding

Surface grinding is an abrasive process. It involves securing the object to a device that will hold it in place (a chuck) before slowly moving the object’s surface across a grinding wheel that’s spinning really fast. This will generate a flat plane wherever the machine comes into contact with the object. It also gives the object an even finish. The longer the wheel spends working on the cutting depth, as well as using a

In an intermittent dress grinding process, substrate builds up on the cutting edges of the abrasive crystals on the wheel. As these edges build up, the cutting forces increase dramatically, and the force causes the grinding wheel to break down and large pieces are actually broken off the grinding wheel. Once this occurs, the grinding wheel must be redressed.

Porosity refers to the open spaces within the bond that allow room for small chips of metal and abrasive generated during the grinding process. Porosity also provides pathways that carry fluids used to control heat and improve the cutting characteristics of the abrasive grains. Without adequate porosity and spacing between abrasive grains, the wheel can become loaded with chips and cease to cut properly.
