Comec ACF170 Cylinder boring-resurfacing machine
The cylinder boring/resurfacing machine ACF170 includes both main reconditioning operations of automotive and truck cylinder blocks - boring and resurfacing - in one single machine, with performances that are usually available only on higher level models. Despite its compact dimensions, the technical features of this machine ensure considerable work capacities, thanks to the wide longitudinal and transverse table feed and to the vertical feed of the head. The excellent qualities of finishing and precision are obtained by combining a tested mechanical structure with innovative technical solutions, which improve the performance and versatility of the machine.
