How spark erosion actually works
• No force or heat is transferred to the parent part when material is being
eroded.
The Spark Erosion Process
• Very low risk of damage to threads.
• Leaves tapped hole ready for a replacement
stud to be inserted.
• Works on the principle of a vibrating spindle with electrical power supply
creating a series of arcs occurring 120 times per second.
• Cutting takes place at the tip of the graphite electrode with 4 bar water
pressure running through the centre cooling and flushing as the material is
being eroded.

Benefits of using spark erosion
Gas turbine removal of blind radial bolts
• Spark Erosion is a fast and effective way of removing the blind radial bolts on
any gas turbine and has been proven to be up to 5 times faster to conventional
drilling.
• Minimum preparation & set up time
• Casing will be ready for lifting quicker
• Allows the customer faster access to the inside of the turbine keeping them on
schedule with there outage plan.
• 24 hr response & cover available on every job

GE workshop Dartford England (Case Study)
• Tie rods cut ready for spark erosion in order to release the seized compressor
wheels.
• 4 techs with 2 machines worked on each shift day/night to complete this job
resulting in GE refurbishing this rotor and returning it to the customer within
the scheduled timescale they were given.
• Delighted customer

Uk power station 2012 (Case Study)
• Boiler feed pump in-situ overhaul,
during annual routine maintenance
shut down, the BFP was the critical
path item to returning the station
on-line
• 16 off end cover studs seized
• Removed by MDS using spark
erosion in only 4 days
• Conventional removal methods
(drilling) estimated at 14 days
• Result BFP completed ahead of
schedule
• Station operator benefitted from
increased generation earnings due
to early station on-line return.
