5-axis Rotary Table TAP for Small, High-Speed Vertical Machining Centers

EXSYS Tool Inc. has introduced a new space-saving 5-axis rotary table TAP for small, high-speed vertical machining centers. The table TAP allows users to upgrade a vertical machining center to significantly increase productivity without incurring the expense of a new machine, according to the company.

In conjunction with the right machine, the 5AX rotary table TAP creates a very compact and economical 5-axis machining center for small and medium-sized workpieces up to a cube of approximately 5.9" (150 mm). It is well suited for automotive suppliers, as well as the medical device, watch/clock and precision mechanical parts industries, and even contract manufacturing.

The 5AX rotary table TAP expands the pL LEHMANN 500 series of modular multiaxis rotary tables from four basic models to five. Adaptable to nearly any workpiece or production situation, 500 series tables can be assembled into as many as 240 different configurations. More than 20 different clamping methods and behind-the-spindle accessories that include rotary unions, special clamping cylinders and angular position measuring systems further extend the system’s adaptability.

Compact pL Lehmann tables consume a minimum of space in the machine work envelope, facilitating optimal tool access to the workpiece. Despite their space-efficient dimensions, the tables and spindles offer strong resistance to pull-out torque and axial force while providing high levels of clamping torque. Engineered for low power consumption and light weight, the tables feature IP67 rated enclosures.

The series includes both single-spindle and multispindle tables that are available in 4-axis and 4/5-axis versions. Swiveling-bridge-style 4-axis tables employ the roto-FIX clamping yoke for machining of multiple parts. The tables’ backlash-free preloaded gear drives (PGD) provide both high torque and high rotation speeds, with spindles capable of 47 to 111 rpm and cycle times for 90 degrees of 0.34 sec. pL Lehmann 5-axis tables operate in simultaneous machining or productivity-enhancing 3+2 positioning modes.

Related Glossary Terms

  • axial force

    axial force

    When drilling, a force that is directed axially—along the direction of machining. The magnitude of an axial force rises with the drill’s diameter and the chisel edge’s width. Axial force is also known as thrust. When turning and boring, the term “feed force” is commonly used instead of “axial force.” See cutting force.

  • centers

    centers

    Cone-shaped pins that support a workpiece by one or two ends during machining. The centers fit into holes drilled in the workpiece ends. Centers that turn with the workpiece are called “live” centers; those that do not are called “dead” centers.

  • machining center

    machining center

    CNC machine tool capable of drilling, reaming, tapping, milling and boring. Normally comes with an automatic toolchanger. See automatic toolchanger.

  • tap

    tap

    Cylindrical tool that cuts internal threads and has flutes to remove chips and carry tapping fluid to the point of cut. Normally used on a drill press or tapping machine but also may be operated manually. See tapping.

  • work envelope

    work envelope

    Cube, sphere, cylinder or other physical space within which the cutting tool is capable of reaching.
