Innovation is the engine that drives progress.
Research is the fuel that keeps it running.
And collaboration is the spark that ignites it all.
It’s no coincidence that the XLO 24-station heavy-duty rolling mill was born right here: from teamwork between two sister companies, CSM MACHINERY and OAKLEY INDUSTRIAL MACHINERY, both part of the CSM GROUP family. Two companies, one shared vision: growing together, listening to the market, and turning customer needs, in this case processing large-diameter heating elements, into concrete solutions.
A Need Born from Listening: Reducing the Diameter Heating Elements beyond Standard Limits
It all begins on U.S. soil, where OAKLEY INDUSTRIAL MACHINERY has a long-standing presence and deep knowledge of the market. It is precisely this local closeness that made it possible to identify a production need rarely seen in Europe: the need to reduce the diameter of heating elements larger than standard sizes.
The vast U.S. heating element market therefore raised a question as simple as it was demanding: does a reduction rolling mill exist that is robust and structured enough to withstand the mechanical stress required to roll large-diameter elements?
CSM GROUP said yes.
From Customer Need to a Shared Solution: the XLO Reduction Rolling Mill Is Born
A long-standing customer shared with OAKLEY INDUSTRIAL MACHINERY the need to reduce the diameter of their large heating elements. This request sparked an intense dialogue between the two companies: OAKLEY’s market knowledge and technical know-how combined with CSM MACHINERY’s technical and engineering expertise, in a genuine exchange of experience and vision.
The result of this shared effort is the XLO 24-station heavy-duty reduction rolling mill: a machine that represents excellence in innovation for processing heating elements with above-standard diameters.
Technical Features of the Heavy-Duty Reduction Rolling Mill
The 24-station rolling mill achieves an area reduction of up to 49%, even on wall thicknesses greater than the standard 1.5 mm, figures that demonstrate the machine’s ability to handle the processing of oversized-diameter heating elements with precision and consistency.
Such a high reduction ratio calls for a machine built from the ground up to withstand it: the entire structure of the rolling mill, from the base to the rolling head components, has been sized to provide the strength needed to handle the mechanical stresses and tensions generated during processing. This is not simply a 12-station mill “extended”: it is a completely different machine, engineered to sustain higher stresses continuously over time, without compromising the quality of the final result.
Advantages of the XLO Rolling Mill for Processing Heating Elements
Production quality
High compaction capacity, maintained even with substantial tube wall thicknesses. Uniformity across the different compression stages ensures the coil remains perfectly centered relative to the tube throughout the entire process.
Perfect straightness of the output element
Despite the intense mechanical stress involved in processing large heating elements, the nozzle-based cooling and lubrication system efficiently dissipates heat, delivering perfectly straight elements.
Capacity to withstand high mechanical stress
The unit has been completely redesigned and optimized for maximum structural robustness. The new design allows for a wider range of input diameters and significantly greater diameter reductions. Thanks to the nozzle lubrication system, the rollers remain constantly lubricated and cooled, allowing the machine to withstand the high mechanical stresses generated by higher compression ratios.
Integrated measuring systems
The machine is equipped with diameter and length measuring systems, providing precise control over the dimensions of the output element at every stage of processing.
Integrated data collection
An advanced integrated software system, accessed via a control panel, collects process data in real time, providing the process capability needed to keep the entire heating element rolling process constantly under control.
One Machine, Two Companies, One Team: the Value of CSM GROUP Collaboration
The XLO oversized-diameter reduction rolling mill is more than a technical response to a production need: it is proof of what happens when two companies choose to move in the same direction, pooling their skills, experience, and vision as one entity, CSM GROUP.
