Impact the accuracy of the machine and instrument

    Due to the surface roughness, large friction coefficient and large wear, so not only reduce the sensitivity of machine and instrument parts movement, but also affect the maintenance of machine or instrument precision.

    At the same time, basing on the rough surface of the real affective contact area is small, under the same load, the unit area pressure of the contact surface increase, which increase the deformation of the surface layer. Namely the surface contact rigidity becomes worse, which affects the working precision of the machine. Therefore, the smaller the surface roughness, the higher the accuracy of the machine or instrument.
