RX2 Plus EVOLUTION
Opis i aplikacje.
The RX2 Plus is a portable in-line boring machine that performs in-line boring and overlay welding on worn holes directly on the equipment. It is designed for the on-site repair of holes and pivot points on both large and small machines. It can also machine the internal surfaces of tubular components in various diameters and pin bores in excavator arms and other heavy equipment—applications where disassembly would result in machine downtime and require transportation to a specialized workshop.
The machine’s new patented mounting system consists of a fixed section and a removable half-moon section. This allows the machine to be installed in either an axial or radial position, depending on the available space and the area to be reached.
The axial feed is unlimited. A simple, effective system allows the 240 mm (9.45”) feed stroke to be reset within the machine’s footprint, without changing the radial or axial position of the cutting tool. The tool remains in the working position, the set dimension is maintained, and no marks are left on the machined surface. This makes it easier to work in hard-to-reach areas, where universal joints and extensions are often used.
The standard equipment includes a Ø 50 mm tool holder shaft and another shaft with conical coupling, measuring 1,150 mm and 1,082 mm, for a combined length of 2,232 mm.
Drive unit weight: 36 kg
The machine can also be equipped with the KIT 2000 facing head, the KIT 30 that allows machining operations starting from a diameter of Ø 32 mm.
The RX control panel automatically adjusts the feed rate based on the load on the rotation motor, helping maintain consistent machining.
With maximum flexibility, the RX2 Plus can independently combine rotation and feed movements to perform:
IN-LINE BORING DIAMETER
MIN. 32 mm – MAX. 450 mm (1.25" – 17.72")
OVERLAY WELDING DIAMETER
MIN. 25 mm – MAX. 450 mm (0.98" – 17.72")

The new RX Series architecture is designed to provide greater stability and precision during machining. The patented axial feed system, which runs on recirculating ball carriages, promotes smooth movement and more precise positioning, helping maintain geometric stability and surface finish quality.
The brushless motors provide consistent torque even at low speeds and responds quickly under load, supporting a steady feed throughout the different stages of machining.
The patented digital control panel makes parameter management and machining monitoring more straightforward, while its built-in diagnostics system help identify operating conditions quickly.
The compact, configurable design allows the machine to be adapted to the requirement of each job, even when space is limited.
The RX patented digital control panel manages rotation and feed and includes automatic functions for controlling in-line boring and overlay welding operations.
- Dedicated operating modes: separate speed settings for boring and welding.
During welding, the machine can be paused and the job resumed with coordinated motor restart. The assistant recommends speed and feed settings based on the selected diameter. - Load control with the ESPS® (Electronic Synchronization Power System): the control panel automatically reduces the feed rate when the spindle is under load.
- Automatic Z positioner: stops the feed at the preset position, adjustable in 0.1 mm increments.
- Color display: shows speed, feed rate, motor load, Z position, preset position, and operating time.
- Self-diagnostics and safety: when powered on, the control panel checks the main components and connections, reports any anomalies, and stores them in the history log. After startup, the motors can restart only once the selectors have been returned to OFF. If communication is lost, the drives stop.
Industry 4.0 data: work data is recorded on an SD card in daily CSV files using MTConnect naming conventions, for integration with digital production systems.
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 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 sacrificing 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:
- 5.5 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.
