New processing technologies for cylindrical hollow components in the RADIAL™ series by EVIRT Italia

EVIRT Italia s.r.l. is thrilled to introduce new, enhanced functionalities for RADIAL™ rolling machine series, including the innovative "Smart Rolling Features," specifically designed for rolling tubes and hollow components.

For over two decades, EVIRT RADIAL™ three moving-slide rolling machines have been a staple for rolling cylindrical hollow components. Inspired by constant collaboration with customers and driven by an unyielding desire to innovate and make its machinery foolproof, EVIRT Italia unveils the latest generation of RADIAL series machines, which offers unparalleled ease of use alongside unmatched reliability, and the ability to perform previously unimaginable rolling processes.

Here is a brief overview of the main distinctive features of the RADIAL series, now in its third generation.

Characterized by three moving slides, the RADIAL™ series is equipped with fully automated setup and piece control systems, alongside a support structure designed through FEM analysis and dynamic simulations conducted through artificial intelligence.

The seamless balance between strength and precision that characterizes EVIRT Italia's rolling machines is further highlighted in the RADIAL™ series. This synergy enables it to uphold its reputation as an "indestructible machine," solidifying its position as a market leader in the realm of three-moving slide rolling machines.

The third-generation RADIAL™ rolling machines have undergone a significant software management and control overhaul, enhancing their versatility and making them even more suitable for shaping a diverse range of profiles as required by the latest applications.

Further advancements compared to previous series are noticeable in integrated safety features, enabling EVIRT Italia's customers to decrease long-term costs, enhance production quality, and boost flexibility among operators through automated setup systems that have minimized manual operations. What once took over an hour for setup has now been reduced to less than 5-10 minutes, specifically the time required for changing rolling tools exclusively.

Of particular note is the highly innovative automatic tool phasing system - Optical Auto-pitching System. Developed using optical systems for micrometric observation of the phase between tools, it can measure and automatically calculate the angular positions of the three tools without any intervention from the operator. The patented EVIRT Italia system doesn't require specific skills from the operators and produces no material waste (no test sample), ensuring perfect alignment, typically not achievable with conventional manual phasing systems.


The third generation of RADIAL™ series rolling machines also introduces a brand-new base frame. While preserving the series' renowned rigidity and strength, this frame has undergone a revision in mass distribution. This adjustment aligns the centers of gravity during operation and further reduces oscillations significantly, particularly those caused by eccentric loads on the pieces being processed.

Throughout the years, the company has consistently showcased its dedication and commitment to ongoing research, achieving certification notably for 13 patents related to the integrated functionalities of rolling machines. In particular, the RADIAL™ series boasts the following features:

- magnetic blocking system of spindles’ inclination (patent pending)
- power saver hydraulic system (patented)
- auto-pitching research (patented)
- auto-calculation of working parameters;
- fully innovative machine’s structure;
- mandrel parallelism lock system.

The EVIRT RADIAL™ series stands out as the most advanced and versatile solution for rolling hollow components, with a specific emphasis on efficiency, high-quality performance, and continuous innovation.

EVIRT Italia s.r.l. is a company with over 50 years of experience in the design and manufacture of advanced rolling machines, providing its customers with comprehensive solutions and dedicated technical support. Its primary goal is to deliver excellence in rolling, coupled with maximizing the quality and strength of its SMART ROLLING MACHINES!
