The UT 250 universal dividing attachment is a precision accessory designed for angular indexing operations and machining of circular components in milling and coordinated machining applications. It is specifically developed for integration with bench milling machines, particularly models FF 230 and FF 500/BL, enabling controlled indexing up to 360°, essential for creating slots, gear teeth, equally spaced holes, and polygonal features.

The indexing system is based on a worm gear mechanism that ensures high positioning accuracy and minimal backlash. The kinematic ratio is designed so that one full turn of the handwheel corresponds to a 10° rotation, allowing precise and progressive adjustment. The handwheel features a zero-adjustable graduated dial, ensuring accurate angle setting and high repeatability in serial machining operations.

The unit structure is designed for rigidity and stability during machining, with the possibility of mounting in both vertical and horizontal positions. This versatility allows adaptation to different machining configurations, improving tool accessibility and enabling complex geometries.

The mounting base is compatible with compound tables featuring T-slot spacing between 45 and 60 mm, ensuring secure and precise installation on small machine tools. The flange interface matches the spindle nose dimensions of the PD 250/E lathe, allowing the use of optional 3-jaw or 4-jaw chucks and significantly expanding operational capabilities.

The Ø100 mm faceplate allows direct clamping of workpieces or the use of additional clamping systems. The unit is supplied with a complete steel step clamp set, including step blocks, threaded studs, nuts, and T-slot fixtures, enabling secure and flexible workpiece positioning. This ensures stability even under variable machining loads.

The device is designed to clamp workpieces up to 20 mm in thickness, making it ideal for precision machining of small components. The high manufacturing quality and accuracy of the indexing system reduce angular errors and misalignment, improving final machining quality.

The UT 250 is suitable for use in machine shops, technical laboratories, and prototyping environments where precise rotational control and high repeatability are required. It is particularly effective for gear cutting, flange drilling, indexing operations, and machining of repetitive geometries.

Thanks to its combination of mechanical precision, mounting versatility, and complete accessory set, the UT 250 represents an efficient solution for indexing and coordinated machining operations on bench milling machines.
