  • Super Twin heads double column type SGS-T4020 ~ T12020PNC Structure

    Structure

    High strength casting iron (FC30) with tempering treatment is utilized, to ensure rigidity, stability, and durability of our double column grinders

    Fixed cross beam structure combines the beam and columns into one sturdy door shape, to guarantee the solidity of the machine

  • Twin heads double column type T2012 ~ T6012AHD/PNC Base Table

    Base Table

  • Super Twin heads double column type SGS-T4020 ~ T12020PNC Lubrication

    Lubrication System

    Force coverage lubrication (oil streams down from upper to lower machine base railways) avoids impacts from lubricant oil pulsation pressure, and allows smooth movements

    The detecting sensor will disable table movement to protect the railways when lubrication oil pressure is not normal

  • Super Twin heads double column type SGS-T4020 ~ T12020PNC Movements

    Movements

    Large twin V is adopted on the machine base and work-table railways, allowing rock-steady table movements, as well as maintains best alignment with equilibrium

    The grinding head movements (vertical & longitudinal travel) are guided by high precision grade ball-screws, and driven by Baldor AC servo motors (PNC type). These features facilitate accurate positioning and micron-precise feeding

    Moving on high density strength steel (S55C), with ultra precision grade linear roller bearings, the grinding head has firm and smooth cross travel with exceptional and accurate cutting ability

    Angular turn on the vertical grinding head is driven by AC servo motor on worm shaft transmission. Numerical insert on desired angle with accuracy to 0.1 degree allows swift angle forming grinding with excellent results

  • Super Twin heads double column type SGS-T4020 ~ T12020PNC Spindle

    Spindle

    High precision in-house assembled cartridge type spindle set uses 6 super precision CP4 grade angular ball bearings, sealed with permanent lubrication. This structural superiority empowers the spindle to grind with low noise, low heat rise, and high precision

    V3 grade motor is integrated with spindle set via couplings for direct transmission, to obtain maximum torque and reduce vibration

  • Super Twin heads double column type SGS-T4020 ~ T12020PNC Motor set

    V3 Motor set

    Japanese brand V3 grade high torque spindle motors are utilized on all double column models. They are thoroughly tested with kinetic balance inspections, capable of remaining low noise, low vibration, and high stability movements even after long period of operation

    V3 grade motor is integrated with spindle set via couplings for direct transmission, to obtain maximum torque and reduce vibration

  • Super Twin heads double column type SGS-T4020 ~ T12020PNC Control System PNC type

    Control System (PNC type)

    Our own design of DSC based NC control system integrates all functions & movements of a large machine into one panel

    Numerical Control system that utilizes AC servo motors on both vertical feed & cross feed

    LCD screen display with digital inputs on panel allows easy operation on various grinding applications

    Easy maneuver and user-friendly design make the machine operation simple, without having to learn complex programming

  • Super Twin heads double column type SGS-T4020 ~ T12020PNC Hydraulic system

    Hydraulic system

    Employs precise electrical circuit to control the proportional hydraulic valve

    The operator can adjust work table speed directly via control panel, increasing work efficiency

    Hydraulic tank temperature is maintained by Habor Coolant system. The coolant stabilizes oil temperature after long hours of operation to guarantee grinding precision and protect hydraulic system parts
