Shaft Machining

Our Field Machining Division recently completed another successful shaft machining project.  The project included initial machining, sleeving of the shaft, and final machining to bring the shaft back to OEM specifications.  The end result was another satisfied customer whose equipment was back up and running as designed.  Great job team!

Contact Us today if you have any upcoming Field Machining projects that we could provide an estimate for.

We are ready for your Journal and Shaft Machining Projects this outage season!

We have successfully repaired thousands of shafts and bearing journals in power and industrial facilities across the globe over the past 25 years. Our unique, on-site machining process requires absolutely no need for shaft rotation, and avoids the issues related to removing and shipping equipment to a shop: costly mobilizations, exorbitant shipping costs, potential damage during shipment, valuable lay down space, and plant crane and rigging requirements. Our finely tuned and safe processes coupled with a full range of equipment ensure customers receive the highest quality at a competitive price. If you have a journal or shaft machining project, planned or emergent, please contact us 24/7/365 for a fast response.

Shaft Welding & Machining

We were recently contracted by a major utility in the Midwest U.S. to repair a damaged shaft at one of their power generating facilities.  The remediation process included machining the existing shaft to remove the damaged area and hard spots, weld build up of the shaft, and final machining to achieve desired diameters and tolerances.  This repair was performed by our trained technicians, utilizing specialty equipment designed for this application.  The end result was a repaired shaft, and a happy customer.

If you have any shafts in need of repair at your facility please contact us to discuss.  To learn more about our shaft repair services please CLICK HERE for the latest brochure.

 

Field Machining

Do you have a maintenance outage coming up this fall?  We offer many types of field machining solutions to facilities all over the globe.  We would appreciate the opportunity to help develop a solution to whatever you may need machined at your facility.   Some common field machining projects that we perform include:

Reduced Cost and Downtime

Performing work on-site eliminates the issues related to removing and shipping your equipment to a shop: costly mobilizations, exorbitant shipping costs, potential damage during shipment, valuable lay down space, and plant crane and rigging requirements. Our technicians are typically set-up in less than four hours and the project can often be completed in less than 48 hours, making this service the ideal solution in critical path scenarios.

Convenience

All work is performed at the customer’s facility, regardless of size, position, damage, material, etc. Equipment available includes a fully-equipped portable machine shop, portable horizontal lathe, and portable vertical turret lathe (VTL). Once on-site, unloading, and loading of our machining equipment is quick and is typically accomplished with a small fork lift.

Flexibility

Our proven equipment and processes can be applied to almost any machining requirement.

 

CONTACT US today to discuss how we may be able to help you with your next field machining project.

Do you have a Steam Turbine Project Coming Up?

Contact us today to discuss the evaluation of your steam turbine components. We will provide a thorough recommendation on what repairs should be executed during this outage to maximize your efficiency and/or reliability, and what can potentially wait until the next Major Inspection.
If you have a tight outage window and require the fastest repair time available, or would simply like competitive pricing for your repairs, we can provide you with options to execute in the most efficient and cost effective manner.

Wind Turbine Machining

We recently completed another uptower wind turbine shaft machining project.  Our equipment and personnel will travel to wherever the problem may be.  For the wind industry, it happens to be 200+ feet above the ground, but we’re happy to do this on your turbine deck or any other area in the plant as well.  Please give us a call if you have any emergent shaft machining needs, we’ll respond quickly and get your equipment back up and running.  For more information on our wind turbine specialty machining services please CLICK HERE.

Collector Ring Re-grooving

We were recently hired to machine and re-groove a set of collector rings on a 7FH2 Generator.  This is a common service we perform during outage seasons when turbine generator outages are taking place and customers inspect the current condition of their collector rings and check groove depth.  When it is noted that the collector rings need machining and/or re-grooving we are contacted to bring in specialty equipment and experienced personnel to perform these repairs on-site.  The collector ring grooves and surfaces are machined, bringing the component back to within acceptable specifications.  If you are ever in need of collector ring machining and/or re-grooving please give us a call.  We’ll tool up and mobilize immediately and ensure we provide you with a safe, quality, efficient performance.  For more information regarding our generator collector ring repairs, see our line card HERE.

Wind Turbine Shaft Machining

 

We recently received a call to perform an uptower repair of a damaged shaft inside a Wind Turbine.  We have experienced technicians that are specifically trained for uptower Wind Turbine repairs, and have the expertise and equipment to successfully execute these projects.  The final results are a safe, quality project – with a shaft that is back within OEM specified tolerances.  The photos below show the before and after of a shaft in need of refurbishment, and the excellent work that our technicians perform.  The end result is another satisfied customer…

Shaft Machining

Our Field Machining Division was dispatched to repair an inboard fan shaft for a Utility customer in the Midwest.  We mobilized a total of 4 specialty field machining personnel, and began the process of machining the inboard fan shaft which had severe shaft damage and hard spots.  We cleaned up 100% of the shaft, had hardness checks performed, and then proceeded to final hone and polish.

The total duration of the project was 3 days from start to finish, and the end result was another satisfied customer.  The photos below will give you an idea of the severity of the original shaft damage, as well as the final condition upon completion.  Another great project by our Field Machining Division!
