The grinding machine provides high accuracy and fine surface finish with minimum tolerances. The machining process is done by the abrasive action of the grinding wheel; the abrasives are embedded over the periphery of the rotating wheel. In Grinding machine grinding wheel is work as a cutting tool and responsible for all machining processes.

Grinding Process. The grinding wheel consists of several abrasive particles which act as minute cutting edges, and these particles are bonded with the help of bonding material. The advantage of using such a process over conventional metal removal processes are as follows. The rate of removal of material is much higher than, say, a traditional file

tion of profile grinding processes, an empirical process model was developed to allow applica-tion of the results from the analogy process to profile grinding. In the analogy process, a large number of trials with profile angles varying from ϕ = 2° to ϕ = 90°, and a stock varying from ∆s = 0.05 mm to ∆s = 0.4 mm, were conducted.

The wet grinding process occurs when a product is transformed from solid to liquid, regardless of its viscosity: paints, inks, enamels, nail varnish, among others. In this process, agglomerates that were not separated in the dispersion phase (due to the electro-physical bonding of some components) are broken by applying extra energy.. This wet grinding process …
