Automotive Industry
For high production automotive parts and components, PEM is the ideal machining solution. The non-contact PEM machining process delivers intricate micro- and macro-structures in metals that are difficult to machine using conventional methods.
Typical Applications:
- Injector nozzles
- Fuel systems
- Valve plates
- Turbine discs
- Gears
- Hydraulic components
- Compressors
- Turbochargers
- Full-form gear profiles
- Crank shaft details
- Critical nuts & bolts features
- Impellers
- Oil flow features
- Pistons
- Planetary carrier shafts

PEM’s stress-free process removes metal atom by atom to produce fully-formed gears
High quality gears for precision meters are machined burr-free, six at a time, in a standard PEMTec machine. Although surface finish is material dependent, many materials are machined to very smooth finishes, with some as good as 1-4 in Ra. PEM machining is a full form precision machining process that usually starts with a solid blank or a preform of the component geometry. The electrode used to machine the turbine wheels in this example is a negative of the turbine wheel geometry less the machining gap for electrolyte. Eight turbine wheels are machined in one 45-minute machining cycle.
