Advancements in CNC machining for railway bogie manufacturing

Unisign, a specialist in CNC machining solutions, is contributing to advancements in railway bogie manufacturing with its range of high-precision portal CNC machines. With over 50 years of experience, Unisign focuses on optimizing machining efficiency, reducing setup times, and improving flexibility for bogie production.

Technical innovations in bogie machining

Unisign’s portal CNC machining centers are designed to enhance key aspects of bogie manufacturing through:

• Time-saving productivity – by reducing cycle times per bogie.
• Flexible configurations – the ability to machine various bogie designs on a single CNC machine.
• Optimized setup processes – horizontal machining combined with single-clamping operations to improve accuracy and efficiency.
• Precision engineering – advanced capabilities for precision in flatness and geometry.
• Enhanced machining techniques – integration of pendulum machining and an optional carousel turning table for precise turning, milling, and drilling operations.

Field-proven performance

Several rail industry manufacturers have integrated Unisign’s CNC machining solutions into their production processes such as:

• Hofmann Engineering (Australia): Faced with the challenge of reducing production time, Hofmann Engineering selected Unisign’s high-speed machining center for its rigidity and efficiency. Machining time per bogie has reduced from 120 hours to just 5 hours with the Unisign machine.
• Medha Servo Drives (India): Known for manufacturing bogies for the prestigious Vande Bharat Express, Medha chose Unisign for its quick cycle times of the UNIPORT6000 and their expertise in machining bogie frames. The Asst. General Manager from Medha reflects, “It has been more then eighteen months since we commenced using the Unisign machine, and we are pleased with its performance.”
• Stadler Winterthur (Switzerland): “Unisign delivers extremely reliable milling machines and we certainly enjoy working with them. They are well-built and, when used in production, are largely fault-free”,  according to Stadler.

The perfect fit for bogie machining

Two essentials stand out for manufacturers of train and tram bogies in this competitive age: productivity and flexibility. The Unisign machinetypes UNIPORT6000 and UNIPORT7000 are reliable machining centres with high dynamics, fast acceleration and short tool changing times. Next to their time-saving productivity they’re also extremely versatile and have impressive dimensions.

Features include angular heads for complete machining of bogie frames, customer specific fixtures, pendulum machining option and the low cost, simple foundation

With a focus on technical accuracy and efficiency, Unisign continues to develop CNC machining solutions tailored to the needs of the rail industry. As railway manufacturers seek greater precision and reduced production times, Unisign’s technology provides a foundation for achieving these goals.
