Arri has recently added a new Soraluce TA35 fixed-bed milling machine to its machine park. This acquisition forms part of an ongoing investment strategy aimed at strengthening production capacity, expanding the range of machinable parts and improving efficiency in high-value-added processes.
The addition of this machine is part of an industrial planning approach aligned with the evolving needs of the market and with the technical profile of the projects Arri typically undertakes, particularly those involving operations that require high structural rigidity, long travels and excellent stability during cutting.
Fixed-bed milling machines as a technical solution
Fixed-bed milling machines occupy a specific position within the CNC machining ecosystem, as they are particularly well suited to operations that demand maximum rigidity, sustained precision and high material removal rates. Unlike more compact machining centres, this type of machine is designed to deliver stable and reliable performance when machining medium- and large-sized components.
The Soraluce TA35 is a clear example of this machine category. Its structural design, featuring a fixed bed and controlled axis movements, enables it to absorb high cutting forces without compromising the geometric stability of the overall structure. This results in greater dimensional repeatability, improved surface finish and high reliability in extended machining cycles.
From a technical standpoint, the machine stands out for its balanced combination of power, travels and advanced numerical control. Its longitudinal, transverse and vertical travels facilitate the machining of large and elongated components, reducing the need for multiple clamping operations or intermediate repositioning.
The spindle, offering high power and torque, is suitable for both intensive roughing operations and demanding finishing processes, ensuring stable performance even when machining challenging materials or large cutting sections. This is complemented by a state-of-the-art CNC control system, which enables the programming of complex tool paths, efficient tool management and the implementation of advanced machining strategies.
The automatic tool changer and the machine’s readiness for process monitoring systems further contribute to increased autonomy and reduced non-productive time, which are key factors in industrial environments where overall equipment efficiency is critical.
Increased production capacity and process efficiency
The addition of the Soraluce TA35 allows Arri to significantly expand the range of parts that can be machined in-house. Its working envelope is particularly well suited to elongated components, valve bodies, large flanges and structural parts that, due to their geometry, do not always adapt optimally to other machining centres.
Another key factor in machining efficiency is improved process stability. The high rigidity of the fixed-bed structure reduces vibrations and deformations, which is essential in long machining cycles or operations requiring tight dimensional tolerances. This helps to reduce rework, improve consistency between parts and ensure compliance with strict technical specifications.
A complement to the existing machine park
The new Soraluce TA35 fixed-bed milling machine integrates as a strategic complement to Arri’s existing machine park, which combines various turning and milling technologies to cover a wide range of part sizes, weights and complexity levels.
The coexistence of large-capacity machining centres with fixed-bed milling machines enables more efficient end-to-end machining processes, reducing reliance on external suppliers and improving control over each stage of the production process, from initial roughing to final precision operations.
Arri: experience and specialisation in large-scale valve machining
Arri has a solid track record in precision machining, with a clear specialisation in the machining of large-scale industrial valves and associated components. Throughout its history, Arri has developed deep expertise in the technical, regulatory and functional requirements of sectors such as energy, oil & gas and offshore, among others.
The experience gained in machining valve bodies, critical parts and large components is underpinned by a combination of highly skilled personnel, well-established processes and continuous investment in advanced technology. The addition of the TA35 fixed-bed milling machine is a further example of this commitment to continuous improvement, aimed at delivering reliable, precise technical solutions tailored to the current challenges of industrial machining.
