Landis DuoFLEX

concentric and non-concentric component grinder

With the capabilities and precision of two Landis LT2e grinding machines in one flexible and compact package, the Landis DuoFlex increases the possibilities for concentric and non-concentric workpiece processing.

Two independent workstations, one grinding machine

The Landis DuoFlex incorporates two independent LT2e workstations, with up to four wheelheads and B-axis options, into one grinding machine. In doing so, it expands what is possible on a single unit with the capability to grind all features: OD plunge, angle spindle plunge, axial ‘bump’ grind, orbital and other non-round shapes. There is also an option for polishing on this machine.

    Proven reliability and precision

    The design of the Landis DuoFLEX is based on tried-and-tested Landis machine technologies. This includes LT2e table tooling and geometry, LT2e-based 28 kW wheel spindles, and a slightly modified Landis Flex 2500 bed. The enclosure also uses LT2 details, where possible.

    HIGHLY CONFIGURABLE PLATFORM

    The Landis DuoFLEX is a highly configurable platform. In addition to two- and four-wheelhead options, a three-wheelhead configuration is available with right, left and center wheelheads.

    Wheelhead slides feature linear bearings on the z-axis, hydrostatic linear bearings on the x-axis, and Fibro swivel with 3-degree Hirth coupling and worm drive.

    Additional key machine features include:

    • Linear motors on all feed and traverse axes
    • Hydrostatic wheel spindles and wheel feeds
    • High precision linear rail traverse axes
    • CBN wheelhead
    • A festoon arrangement of power cables to reduce assembly time
    • Reduced power consumption and overall floor space compared to two equivalent machines
