RX Evolution SERIES

The axial FEED SYSTEM uses a lead screw and profiled recirculating-ball linear guides. This solution reduces friction and ensures smooth, consistent, and repeatable movement throughout all line boring and overlay welding operations:

• The preload maintains continuous contact between the lead screw nut balls and the lead screw, reducing backlash during direction changes and improving positioning accuracy. The guide balls are arranged in four rows in an X configuration to provide high rigidity, load capacity, and stability under radial, lateral, and combined loads, including torque moments.
• The low coefficient of friction makes the feed smoother and more progressive, limiting stick-slip, jerking, and sudden stops. This results in better surface finish and greater machining reliability, even under heavy loads.

The feed system is positioned beneath the machine body in order to reduce overall dimensions and facilitate installation.

The rapid stroke recovery system restores the available feed without changing the position of the tool relative to the surface being machined.

The operation takes place within the machine's footprint, without requiring additional space and without altering the set dimension or leaving marks on the machined surface.

The stroke can be configured to meet different operating requirements, adapting the machine to the application without compromising on precision or stability.

Movement is powered by state-of-the-art brushless motors—a perfect blend of power, precision, and energy efficiency—delivering top-tier performance across the entire system:

• 5 Nm to 11 Nm of rotational torque (depending on the model);
• 0.45 Nm of linear feed torque;
• precise motion control;
• high dynamic responsiveness;
• efficiency of up to 95%;
• stable torque, even at low speeds;
• instantaneous response under load;
• consistent speed during operation.

The design of these brushless motors also ensures an excellent torque-to-weight ratio—enhancing compactness, ease of handling, and overall performance—while reducing wear and maintenance requirements to extend the service life of the entire system.

The structure is made of high-strength anodized 6082 aluminum, a solution that combines high rigidity with low weight.

This configuration improves geometric stability and helps limit vibration and deflection during line boring, precision boring, and overlay welding operations.

The arrangement of the components also allows the operator to access the main feed system for inspection and checking activities.

The new installation system consists of a fixed body and a removable half-moon element.

This configuration allows the machine to be installed either axially or radially, providing greater flexibility when the available space or component geometry makes conventional installation difficult.

Precision becomes control.

The new RX control panel integrates rotation and feed management with automatic Z-axis positioning and monitoring of key machine data:

• Dedicated modes and speeds for line boring and overlay welding.
• Automatic Z-axis positioning stops the feed at the set position.
• Feed automatically reduces when the spindle is under load.
• A color display shows speed, motor load, Z-axis position, and target position.
• Startup diagnostics report and record faults; the drives stop if communication is interrupted.
• Daily CSV data logging to an SD card, with MTConnect data names for automatic MES import.

The RX Series introduces a new mechanical architecture and new precision kinematics, developed to increase structural rigidity, improve motion control, and make machining more stable and efficient.

An evolution of the WS Series, RX line-boring machines are designed for the on-site repair of worn bores, pin seats, internal surfaces of tubular components, and pivot points in the earthmoving, mining, marine, railway, oil and gas, energy, and industrial maintenance sectors.

They operate directly on the component, even in confined spaces and areas with limited access, eliminating the need to disassemble the machine or transfer the parts to be repaired to a workshop.
