Large Boring Bar - 12m bar for big casings

As industrial plant and equipment becomes more sophisticated to cope with modern technology so manage-ments’ determination to minimise operational downtime increases, as it is becoming a very expensive commod-ity. Metalock understands the importance of getting the job done within the constraints of time and budget andits expertise is generating significant savings in both time and cost over a broad spectrum of industries includingpower generation, steel and aluminium, marine, pulp and paper, petrochemical and offshore.

Metalock Engineering has been serving industry with mechanical equipment repairs for nearly 60 years andduring that time has accumulated a wealth of experience in the art of in-situ machining. The technology savesmoney in that no longer is it necessary to dismantle and uproot machinery for transportation to a workshop forrepair. Instead, Metalock move in and effect the repairs on site.

The range of services offered by Metalock extends from milling, boring, drilling & tapping to orbital turning andfacing. It also carries out Metalock repairs – metal stitching — to a whole gamut of cracked and broken compo-nents and housings, and restores them to as good as new condition.

The company operates in a broad range of industries world-wide and over the years has designed and built anextensive array of specialist machines for on-site working, latest of which is a 12-metre long boring bar for in-situturbine machining applications. The unit has been developed to fulfil a demand for precision machining on largecylinders, turbine and compressor casings and is capable of performing a comprehensive range of in-situ machiningoperations on units up to 500MW.

The boring bar has been designed complete with an integral gearbox and a universal plate to facilitate align-ment. Being modular, the bar can be extended from 2 metres up to 12 metres long and has a machining capacityup to 5 metres diameter. These parameters make it eminently suitable for the larger applications found in thepower generation industries around the world.
