Line Boring

Why Line Bore?

Not only is it faster but, proper line boring provides the most accurate hole geometries when compared to honing, reaming or other similar processes. When retrofitting existing coupling bolts with advanced hydraulic coupling bolts, close tolerance line boring ensures that the full benefits of such bolts can be realized.

How Fast?

From parallel task operation to simultaneous multiple coupling machining we can provide you with myriad options to minimize or even eliminate critical path impact. In cases of hydraulic coupling bolt upgrades, specialized BFW teams have always assured clients of an average time of 2 hours per hole to line bore a hole, machine new bolt sleeves and fully install each bolt assembly.


Our Capabilities

Boring Range: 1 1/2” to 5” hole diameter

Coupling Length: 3” to 36” face to face

Coupling Diameter: Max to date is 60” diameter

Large Coupling Machine

Turnkey Project

BFW provides a turnkey project that includes a BFW Coupling line boring machine and a full sized engine lathe. This enables our team to be self sufficient while on-site. The team is able to bore the coupling holes, turn hydraulic coupling bolt sleeves or conventional coupling bolts and install hydraulic coupling bolts without any assistance from plant personnel or hired craft labour.
