A large number of studies have shown that the height of a residual material is the key factor affecting the surface quality of ultra-precision grinding. However, the grinding process contains several random factors, such as the randomness of grinding particle size and the random distribution of grinding particles, which cause the complexity of the material removal process.

n Safe grinding with a 2,5 mm thin disc, ideal for hard-to-reach areas. n Less heat discolourations when grinding. Maximum work safety thanks to the optimum three-layer reinforcement of the disc.
