Advanced CNC control provides powerful function and high efficiency.
Teach-in operation control for easy operation.
Servomotor drives on 4 axes assure high speed motions and high positioning accuracy.
Regulating wheel is driven by a servomotor, providing variable speed change.
The structural parts are manufactured from high quality cast iron, heat treated and stress relieved for maximum material stability without deformation.
The grinding wheel spindle and the regulating wheel spindle are precision machined from Nickel Chromolybedenum alloy steel (SNCM-220). Both spindles are subject to various heat treatments, making the machine ideal for heavy duty machining and high precision grinding.
The feed screw employs high precision ball screws, normalized and high frequency heat treated for maximum wear resistance.
