Spark erosion machine operator
Spark erosion machine operators set up and tend spark erosion machines designed to cut excess material from a metal workpiece by the use of electrical discharges, or sparks, caused by electric voltage and separated by a dielectric liquid, which removes pieces of metal from the electrodes. These applications can involve transmission and optical microscopy.

About spark erosion machine operator
As a spark erosion machine operator, you will work with precision electrical discharge machinery to shape and refine metal workpieces with extraordinary accuracy. Your daily responsibilities include setting up complex spark erosion machines, monitoring their operation, and troubleshooting issues to ensure consistently high-quality output. You'll work with various metal types, applying electrical discharge technology to remove excess material through controlled sparking processes separated by dielectric liquids. This role requires precision, attention to detail, and technical expertise—you'll operate measuring equipment, interpret technical specifications, monitor automated processes, and manage quality standards throughout production. Spark erosion is a critical process in manufacturing, particularly in industries such as automotive, aerospace, tooling, and precision engineering where tolerances are measured in micrometers. The Polish manufacturing sector, especially in Silesia and Greater Poland, has strong demand for skilled spark erosion operators as companies continue to invest in advanced precision manufacturing capabilities.
