Notes: A low-cost, spark-erosion cutter for stain-free cutting of conducting materials in samples of specific shapes, has been built. A servo system monitors the distance between tool and sample, and advances the tool towards the sample when necessary in a controlled way. Advancement rates of between 0.4 and 3.0 mm/h are presently used but with other gear ratios for the motor it could be changed to almost any practical value. Cutting rates of typically 1–1.5 mm/h are used. The cutter works quite well, is within the financial reach of smaller laboratories, and can be built in a local machine shop.
