[Talk to a U-Axis Expert](https://www.cnc1.com/solutions/machine-enhancements/u-axis-integration#contact)[See What It Can Do](https://www.cnc1.com/solutions/machine-enhancements/u-axis-integration#operations) ![D'Andrea logo](https://www.cnc1.com/hubfs/machine-enhancements-2026/dandrea-logo.png) Leading U.S. Integrator for D'Andrea U-Tronic heads Fully Integrated with your FANUC CNC Vertical & Horizontal machining centers ## Productivity & Flexibility The D'Andrea U-Tronic is an NC boring and facing head. Interfaced to your FANUC CNC, it turns your machining center into a machine that can also face, bore, thread and profile, without moving the part to a lathe. The head is available in several sizes and is compatible with most machining centers.

Outer facing Inner facing Back facing Cylindrical & conical boring Threading Concave & convex corner rounding Spherical operations ## Two Ways to Add a U-Axis Choose full CNC integration or a simpler standalone positioner. Fully Integrated U-Tronic Integrated to the FANUC CNC and loaded into the spindle by the automatic tool changer like any other cutting tool. The U-axis is synchronized with your machine axes for facing, boring, threading, corner rounding and spherical work. This is how most applications are set up. U-Control Positioner A simpler U-control positioner with a wireless remote. The axis is not synchronous with the FANUC CNC axes, but still allows turning, boring, facing, internal, external, threading and conical operations. ## How It Works 1 Load The ATC loads the U-Tronic head into the spindle like any other tool. 2 Couple The head couples to a servomotor mounted on the side of the spindle. 3 Enable The U-axis is enabled automatically by the FANUC control. 4 Machine The machining process continues uninterrupted. ## Why CNC Engineering Leading U.S. Integrator We are a leading U.S. integrator for D'Andrea U-Tronic systems. Proven Installations U-Tronic systems installed on a wide variety of vertical and horizontal machining centers. Electrical & Mechanical Expertise Unmatched experience with the electrical and mechanical installation requirements of these systems. ## U-Axis FAQs Answers to the questions we hear most about adding a U-axis. What is a U-axis boring and facing head? A U-axis head such as the D'Andrea U-Tronic has a cutting tool slide that moves radially while the spindle turns. Controlled as an extra axis, it lets a machining center perform facing, boring, threading and contouring operations normally done on a lathe. Will a U-Tronic head work on my machine? The D'Andrea U-Tronic is available in several sizes and is compatible with most machining centers. We have installed U-Tronic systems on a wide variety of vertical and horizontal machining centers. Tell us about your machine and control and we will confirm the right setup. What is the difference between a fully integrated U-Tronic and a U-control positioner? A fully integrated U-Tronic is interfaced to the FANUC CNC, loaded by the automatic tool changer and synchronized with the machine axes. A U-control positioner uses a wireless remote and is not synchronous with the CNC axes, but still allows turning, boring, facing, threading and conical operations. Is the U-Tronic head loaded by the tool changer? Yes. In most applications the U-Tronic head is loaded into the spindle using the automatic tool changer like any other cutting tool. It couples to a servomotor mounted on the side of the spindle, the U-axis is enabled automatically and machining continues uninterrupted. ## Ready to Expand Your Capabilities?
