According to Sarix SA, its SX-100 and SX-200 EDMs show that sinker-style machines can erode deep cavities and small holes — as small as 20 μm. The microEDMs impart surface finishes as fine as Ra 0.1 (Ra 0.05 when fitted with the company's Micro Fine Pulse Shape Generator). The SX-100 has a 530mm x 270mm worktable and the SX-200's table measures 700mm x 300mm. X, Y and Z axes are standard on the machines; W, A, B and C axes are optional. Both machines come with Sarix's new multi-axis CNC, the SX-CU, which allows the indexing of complex workpieces.

Among the electrical-discharge machines Sodicksells is an innovative EDM that can drill a 2.9μm hole.

Optimation Inc. has developed a microEDM system, in the U.S.A., that drills down to less than 10μm diameter.

GF AgieCharmilles'new CUT 1000 wire EDM machine, introduced in the U.K., is designed specifically for very precise micromachining applications, and replaces the company's AC Vertex 1 machine.
