About Spark Erosion
By creating a constant series of intermittent arcs between the workpiece and an electrode, a cutting movement is being accomplished which will break down the hardest metals.
Spark Erosion is a method of metal disintegration that is accomplished by creating a cutting movement between the workpiece (seized bolt, nut, shaft, tap,...) and an electrode held in the cutting head of the metal disintegrator machine. The electrode vibrates and will create a series of intermittent arcs resulting in the gradual disintegration of the workpiece. The powdered, disintegrated workpiece particles are being flushed away by a constant flow of cool water, as a result there is no heat transfer to the surrounding material. Neither the structure nor properties of the base material will change because of the disintegration process. As we only cut the seized workpiece, a complete and full recuperation of the thread will be possible.
Spark Erosion is widely applicable and can be used to cut through any electricity conducting material. The shape and dimensions of the electrode used is designed and calculated specifically for the workpiece and can vary in shape (square, circle, rectangle,...) and dimensions (M3 - M200). For larger workpieces, multiple cuts might be necessary.
In most cases, Spark Erosion offers a solution to cut parts not achievable by classic on site machining techniques (grinding, milling, drilling,...).
Spark Erosion is the fastest (and as a result the cheapest) technique. For smaller workpieces, with a diameter less than 50 mm, a cutting speed of approximately 2mm per minute can be achieved. For bigger sizes (up to 200mm) we average a cutting speed of 1mm per minute. The harder the material, the faster the cutting speed.
And last but not least; Spark Erosion is by far the safest technique for surrounding materials, environment and operators. No rotating or fast moving parts, no use of chemicals or oils, no heating and no high voltages are to be used. In our 25 years of operation not a single accident has occured!

NO DAMAGE TO SURROUNDINGS
No heat transfer to surroundings, no changes in structure and properties of base material. Complete and full recuperation of the thread.
FAST
Average cutting speed of approx. 1mm per minute. The harder the material, the faster.
WIDELY APPLICABLE
For all possible shapes and depths, even in difficult reachable locations. Can be used for all electricity conducting materials.
ALTERNATIVE FOR MACHINING
When classic machining techniques are not an option (because of accessibility, integrity of surrounding material,...), Spark Erosion is often the only solution.
SAFE
No rotating or fast moving parts. Sparks are cold and can be contained by plastic or shroud. Low voltages, can be used in confined space. Not a single accident during our 25 years of operation!
