Extended U-TRONIC Head: a special solution for deep turning
21 May 2026
The extended U-TRONIC head is one of the special solutions developed by D’Andrea for deep turning applications requiring high precision, stability and reliability where extended machining depths are needed.
Designed to operate under critical working conditions, the extended version retains all the distinctive features of the U-TRONIC system, ensuring high structural rigidity, effective vibration control and excellent accuracy – key factors in achieving consistent profile quality.
Continuity with the standard U-TRONIC range
The extended version complements the established range of electronically controlled standard U-TRONIC heads – from the UT3-360S to the UT8-1000S models – further expanding their application scope. It originates from the experience gained in the development of special solutions and represents the natural evolution of the standard range for machining operations that exceed traditional dimensional limits.
75 years of D’Andrea expertise
This special head embodies D’Andrea’s know-how, as the company celebrates its 75th anniversary in 2026. Seventyfive years of experience in designing solutions for stationaryworkpiece turning translate into reliable applications developed to meet the most advanced requirements of precision engineering.
