Design & Manufacturing of Custom Servo Control System for a Vertical Face Wood Veneer Slicer

Worker at veneer slicing machineTo design and create a custom servo control system for a slicer machine, the application required that the machine slice logs weighing nearly four tons with a precision tolerance. To achieve this demand, IIS designed a 5-Axis automation control system that incorporated 3 servo motors, servo drives and 2 hydraulic servo valves all linked via a SERCOS fiber optic network. We were able to not only design, but also fabricate a 36″ x 16″ x 60″ NEMA type 12 machine enclosure to house all of the control components.

The custom slicer machine is capable of controlling slicing thicknesses from .005″ to .250″ while maintaining a tolerance within .001″, all with the push of a button controlling the servo valves. Compared to the usual manual adjustments, this innovation saves customers an immense amount of time in blade angle, and sheet thickness adjustments. We also offered on-site machine commission, including a thorough code debugging and a check of all the installation wiring.


This servo control system is fitted to a vertical face veneer slicer machine that can slice logs weighing nearly four tons with a precision tolerance.
