ECM Developments Ltd provides a specialist electrochemical machining capability to aerospace, automotive, defence, nuclear, oil and gas, medical and other industries.


Electrochemical De Burring – ECD

De burring of sharp edges on conventionally machined components, using dedicated tooling on auto cycle ECD machines. Particularly relevant to deep intersecting bores and consistent de burring of machined features that cannot be accessed by traditional burr removal methods

Static ECM of Shallow Grooves – ECS

Production of shallow channels in the surface of components such as oil lubrication channels, grooves for high speed air bearings and circulation channels in fuel cell plates and micro fluidic devices.

Electrochemical Plunge Forming / Drilling – ECF 

Forming of two dimensional shapes and holes of any cross sectional profile with straight or helical axes. Forming of three dimensional surfaces such as aerofoil blades, gas turbine blisks and integrally bladed pump impellors, using purpose designed tooling on auto cycle ECM machines.
Electrochemical Turning – ECT

Machining of thin wall rotational section components such as high performance flexible diaphragms in extreme duty metals, using an electrolytic spindle and plunge ECM tooling

Precision ECM (PECM)

PECM delivers a higher level of precision compared to traditional ECM through the use of advanced technology that “pulses” the electrode and rectifier power as machining proceeds.

Pulsing allows smaller machining gaps and high levels of flushing efficiency to be used during PECM to produce accurate three dimensional forms with a good surface finish.  PECM removes metal much faster than EDM (Electro Discharge Machining) and component hardness is of no consequence.

Compared to EDM, there is no electrode wear, refurbishment costs or electrode changing in process. There are no potential re cast surface layer effects requiring benching as metal is removed in a different manner during PECM.  In house capability includes vertical axis sink PECM and three axis CNC PECM systems, to suit R&D and production requirements.
