Collector Ring Machining


During any turbine generator outage season we often receive an influx of calls to perform collector ring machining on various makes and models of generators.  It is critical to maintain as much brush to collector ring contact as possible, and machining the rings can make sure the surface is free from defects that may inhibit brush to ring contact.  The need for this machining is typically determined after the generator has been disassembled and inspected, making this service an emergent repair that needs to be performed within a time-sensitive window.  When these requests are received we typically request basic dimensional data and then provide a quick quotation for services.  Once approved, we immediately dispatch our qualified technicians to site along with specialized machining equipment.  This work is typically completed in 1-2 shifts, and the customer is able to continue forward without this service having any impact on the overall schedule.
