This machine is used for honing of cylinder block bores, cylinder liner bores etc.
Hydraulic cylinder bores,precision bores etc. Roundness 0.0025mm and surface finish
Ra 0.4 can be obtained.Bore taper can be corrected by using short stroke.
Features:
simple structure, easy operation and high working accuracy.
Reciprocation head is hydraulic driven.
Expansion and contraction of honing head is controlled by thefeed handwheel directly.
