SECO Tools recently introduced the BB732 Boring Bridges which are made to work seamlessly with Steadyline® Bars, for deep boring applications with larger diameters. One of the standout features is the optimized coolant flow – it’s directed right at the cutting edge to help break up chips for better surface finish and longer insert life. The flexible design lets you use the same bridge for both roughing and finishing, so you get more done with fewer tools.
One Bridge Bar, dual purpose: Roughing and Finishing
The BB732 bridges support both roughing and finishing operations, eliminating the need for separate tools and reducing inventory costs. This dual-functionality makes them a cost-effective solution if you are looking for flexibility without sacrificing performance.
Manufacturers often face the challenge of using separate tools for roughing and finishing, which adds to both cost and operational complexity. The BB732 bridges provide an effective solution with their modular design that supports both operations in a single setup—streamlining the tooling strategy, improving efficiency, and significantly reducing overhead.
Precision meets performance with BB732 Boring Bridges
The BB732 Boring Bridges are engineered for seamless integration with Steadyline® SM40 bars, delivering unmatched performance in deep hole boring applications for larger diameters. They are lightweight and modular, so you get the strength and stability without the bulk. Thanks to the coolant flow targeted directly to the cutting edge, the BB732 is ideal for high-precision, high-efficiency operations.
Manufacturers often face two key challenges in machining operations. First, using separate tools for roughing and finishing increases both cost and complexity. Second, achieving deep boring with conventional heavy bridges can result in tool incompatibility and poor machining performance. The BB732 bridges address both issues through an innovative modular design that supports roughing and finishing in a single setup, while being specifically engineered for Steadyline® bars. This combination enables deep boring with lightweight, vibration-controlled assemblies—streamlining tooling strategies, improving precision, and reducing overall overhead.
Vibration-free machining for flawless surface finish
The BB732 bridges, when paired with Steadyline® technology, offer up to three times greater dynamic rigidity than conventional holders. This ensures stable machining even with long overhangs, maintaining tight hole tolerances and delivering excellent surface finishes. The result? A boring tool that truly controls vibration and enhances productivity.
Manufacturers often struggle with vibration issues when working with long overhangs and unstable assemblies, which can easily compromise surface quality and machining accuracy. The Steadyline® technology, combined with BB732 bridges, effectively minimizes vibration—allowing high-speed, high-precision boring even in challenging setups. This results in superior surface finish, improved stability, and greater overall productivity.
Designed for operator comfort and efficiency
Every detail of the BB732 bridges is crafted with the user in mind. From the vernier scale to laser-marked torque values and safety information, these features enhance usability and reduce set-up time. The integrated safety stopper also prevents block ejection, ensuring a safe and reliable operation.
Complex setups and unclear instructions can slow operations and increase errors. The BB732 bridges solve this with intuitive markings and an ergonomic design that make setup simple and boost operator confidence.
Sustainable innovation with digital documentation
In line with modern sustainability goals, BB732 bridges come with paperless documentation. A QR code provided with the product links directly to digital user instructions, reducing paper waste and ensuring that the latest information is always at your fingertips.
Managing physical documentation can be time-consuming and unsustainable. The BB732 bridges enable a paperless workflow with digital access to all product instructions through a convenient QR code.
