Advanced Special Process Technology

3g STEM Drill

A new generation STEM (Shaped Tube Electro-chemical Machining) system that overcomes the negative aspects of the process. This system is a single unit machining centre enclosing the process and the acid systems in a single unit; and incorporating many new features.

The machine is a twin work-station system. This allows one work -station to be loaded whilst the other is machining, improving machine efficiency by approximately 60%. This feature is especially useful when machining Turbine blades that have a “Tip” operation and a “Root” operation.

The system uses absolute encoders on the Z axis and therefore eliminates the need to reference on power- up which would usually necessitates resetting the STEM tubes in their guides. The control system has advanced process monitoring and graphing capabilities, and the machine is entirely constructed from stainless steel.
