BB5500 Coupling Boring Machine

The CLIMAX BB5500 Coupling Boring Machine is engineered for high-precision coupling boring in turbine and large rotating equipment applications. Designed specifically to bore fitted coupling bolt holes in large couplings and flanges, the BB5500 delivers exceptional rigidity and accuracy to produce straight, round bores for precise bolt fit. This level of precision makes it an ideal solution for turbine coupling applications where proper alignment and reliability are essential.

Built for efficient field machining, the BB5500 is easy to set up and performs reliably in confined spaces where traditional boring machines cannot operate. Features optimized for quick setup and repeatable accuracy help reduce downtime during turbine overhauls and maintenance outages. From turbines to other large coupling applications, the BB5500 provides fast, accurate coupling bolt hole boring while minimizing shutdown time and rework.

Powerful, versatile and easy to use

Quickly bores precisely aligned bolt holes the first time.

Eliminates the need for lengthy honing procedures.

Universal coupling mounting system adapts to all sizes of commercially available turbine couplings.

Quick removal of the boring bar without disturbing setup. This allows measuring and inspection of the bore.

Multiple feed options to suit your requirements.

Reversing mechanical feed for limited space applications that allows back spot facing and counterboring.

Electric feed allows reversing and also rapid tool return.

Multiple drive options—hydraulic, pneumatic, or contact your sales representative for custom electric drive options.

Switch easily between high speed steel or carbide tooling.

Compact Design

Extremely rigid and very compact.

Easily fits into confined spaces.

Simple one operator setup.

Minimum clearance Rotation Drive and Axial Feed only requires 2.0 inches (50.8 mm) clearance between the coupling hub OD and the bolt center.
