Centerless grinding is a process of grinding metal workpieces to precise dimensions, generally in the range of 0.010 inches to 0.500 inches, with a conical or cylindrical grinding surface. Moreover, it is an excellent process for producing precision parts that need to be small and round. It is also valuable to use for various other tasks, from ...

It is easy to obtain the near-polished grinding surface using fine-size grain diamond wheel (such as #2000, grain size 6.5 μm) and a small grinding depth. However, a relatively big-size wheel (such as #600, grain size 24 μm) is difficult to accomplish the near-polished grinding. Hence, this paper proposes a novel axis-feed grinding approach with …

The biggest challenge for ultra-precision grinding is to reduce the grinding tool wear to a negligible amount or make the wheel worn in a predictable way. Therefore, diamond and CBN are the two most frequency used abrasives for ultra-precision grinding due to their super hardness and wear resistance. The disadvantages of traditional super ...

In camshaft grinding, as the De is larger while grinding the flanks, higher power will result if the radial infeed and work speeds are maintained the same as when grinding the nose or base circle. This can result in unacceptable thermal damage on the lobes. In order to avoid this problem, the work speed is generally reduced as the wheel …

Precision grinding takes very small depths of cut at a fast feed rate. The action is more of a polishing/rubbing action than stock removal. The specific energy (the energy required to remove unit volume of material) is high, and more of that energy transfers into the workpiece surface. It takes over 200 sec to remove 1 in.3 (16.4 cm3 of material.

Usually vitrified wheels are used at speeds less than 6,500 surface feet per minute. At higher speeds, the vitrified bond may break. Organic bond wheels are generally the choice between 6,500 and 9,500 surface feet per minute. Working at higher speeds usually requires specially designed wheels for high speed grinding.
