SPARK EDM MACHINING

Spark EDM machining, like Wire EDM, uses spark erosion to machine blind cavities.

This process employs machined electrodes that produce sparks along the surface of the electrode to sink or plunge the cavity. The Sinker EDM process is ideal for a number of applications:

  • Blind Cavities
  • Intricate Details
  • Sharp Corners
  • Fine Finishes (Surface Finishes to 10 microns)
  • Thin Walls and Cross Sections
  • Machining Threads into Hardened Parts
  • Blind Keyways
  • Internal Splines, Squares, or Hexes
  • Tolerances can be held to .01 mm

 

Electrodes
tlas Tooling  has complete in-house Electrode manufacturing capabilities. Electrodes for Spark EDM machining are generally made from Copper or Graphite depending upon work piece material and electrode wear requirements.

Machines
We have 4 spark EDM machines with maximum capacity of 1,200x800x500 mm.
