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.
