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 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 CONNECTABLE SHAFTS WITH CONICAL COUPLING are the result of in-depth research conducted by Sir Meccanica.
The main purpose of our Research and Development work is to continue the commitment started years ago on precision coupling joints and their relative resistance to mechanical stresses 
In particular, we conducted studies on the locking mechanisms of conical couplings, which are used to assemble rotating and stationary parts capable of transmitting high torsional moments, or to join thin axial components, extended in length and capable of withstanding large torsional torques and bending moments.
Perfectly adaptable to both minimal and infinite processing lengths, the patented system is composed of various modular components of different sizes that, assembled together, achieve the required dimension. In fact, the modularity of the system makes Sir Meccanica’s brand products and technologies even more unique. The key advantages of our shafts are: 

• immediate coupling and uncoupling, for continuous assembly and disassembly;
• precision and quality in coaxial alignment under any stress conditions; 
• excellent control over interference levels between coupled surfaces;
• resistance to wear and stress over time;
• high torque transfer capability;
• increased safety factors;
• interchangeability.
