Facing portable line boring machine BB7100

Product Overview
The CLIMAX BB7100 line boring machine is a modular, high-capacity solution engineered for precision line boring in heavy equipment repair, industrial maintenance and fabrication. Bore strokes are limited only by bar length; modular bearing supports and interchangeable components enable fast configuration for on-site or shop machining.

Product Advantages

• Portable with station-class power: hydraulic drive delivers high torque at the bar for large-diameter boring.
• High-torque hydraulic motor (example: 11.3 in³ / 185 cm³, approx. 2280 ft‑lb / 3090 N•m at 29 rpm).
• Wide machining range: bore diameters 10.25–58.25 in (260.4–1479.6 mm); facing range 9.6–62.5 in (243.8–1587.5 mm).
• Modular, compact components for fast setup; many parts liftable by hand to reduce downtime.
• Optional dual-action boring/facing arms and two-head operation for combined or simultaneous operations.
• Chromed, gun-drilled bars with straightness to 0.001 in per ft and optical target options.
• Accepts industry-standard tooling with nominal 1 in (25.4 mm) square shank; field-adjustable half nut and backlash adjustment for on-site serviceability.

Design and Features

• Split-frame modular tool carrier transmits machining forces directly to the bar via adjustable guide shoes.
• ID and end-mount bearings use spherical taper-lock roller bearings; end mount adjustable ±0.625 in (15.9 mm) for centering.
• Full-length square ways on boring/facing arms for quick positioning; rotatable tool post for flexible setups including limited cantilever configurations.
• Net-fit tool carrier can be clamped for facing or set for boring to remove clearance and maximize rigidity.
