Robbi Lyor S Series Horizontal Tube Honing Machines

Description

Horizontal honing machines LYOR are distinguished by their rigidity and power. A hydraulic cylinder controls the honing head movement. Three phase electric motor controlled by a vector inverter, servo-ventilated controlling the spindle rotation. The drive transmission is through a gear-box in which the gears are hardened and ground, projecting high torque and stock removal. Programming is very easy with the ‘touch-screen’. The visualisation of all the working data enables the operator to attend during the working cycle.
