U-TRANSFER

Product catalog summary

Overview: The document provides technical specifications and operational details for D’ANDREA SpA's U-TRANSFER boring and facing heads, designed for mass production applications on transfer machines, drilling units, and special purpose machines.

Specifications: The U-TRANSFER heads are available in various models (TNF-S 100, 125, 160, 200) with specific dimensions and technical parameters. Key specifications include diameter, stroke, spindle size, and tool holder dimensions. The heads are equipped with a coolant system and require specific spindle supports and a driving unit for operation.

Technical Data: The document lists detailed measurements for each model, including flange dimensions, tool holder specifications, and interface flange details. The heads operate with a drawbar mechanism, ensuring precise movement through tight tolerances and special heat treatments for high surface hardness and low friction.

Operational Procedures: U-TRANSFER heads are used for various machining operations such as inner and outer facing, turning, grooving, and threading. The tool-holder slide is mechanically driven by an axial drawbar with rack and pinions, allowing manual adjustment of backlash.

Recommendations: To ensure optimal performance, the machine tool must be equipped with properly dimensioned spindle supports and a driving unit to control the drawbar. The pulling force of the drawbar is influenced by spindle RPM, slide stroke position, and tool weight.

U-TRANSFER are boring and facing heads with axial driving for mass production application on transfer machines, drilling units and special purpose machines. The slide feed is controlled by a drawbar joined to a driving unit located in the spindle rear area and directly managed by machine CNC. U-TRANSFER heads are used for inner, outer and undercut facing operations, inner and outer turning operations, grooves, phonographic spirals, straight and taper threads, profiling thanks to the interpolation with all the machine tool axes. Tool-holder slide of the U-TRANSFER head is mechanically driven by...
