Lunette to 16k20 mobile

Lunette — machine adaptation. Purpose of a lunette — an additional support in order to avoid a deflection of preparation or the main when processing on the lathe or the grinder.
Lunettes happen to support of swing and sliding, the first call roller L., and the second - cam L. Naiboley lunettes with manual independent movement of cams are widespread, however, on machines with ChPU the greatest application was found by H.p. a hydraulic actuator self-aligning.
Special L. for grinding of rings of bearings, rollers in the centerless way call boots.
L. substantially influence processing accuracy: errors of a geometrical form of a basic (podlyunetny) surface are transferred to the processed surface. At the same time they can decrease, increase, be displaced on a phase (to turn). The coefficient of transfer is defined, including, a design of lunettes.
The minimum coefficient lunettes of a special design - correcting possess.
