Producing deep holes in hardened materials.

STEM Drilling

STEM Drilling is the process of producing deep holes in hardened materials using the combination of an electrical current and acid such as Sulphuric and Nitric acid.

It is commonly used in forming apertures in land-based turbine blades. However, at MPP Technologies we can build a tailored STEM machine, control unit and power supply to meet your specific requirement.
