We support the latest innovations and advanced part development for jet aircraft engines, rocket engines, turbochargers for truck engines, power generation, and petrochemical applications. This includes diameters from 10mm to 1100mm, and very basic airfoil shapes as well as advanced ...

For electrochemical action, an electrolyte solution is pumped into the workpiece which acts as an anode. The ECG process uses a conducting grinding wheel in which an insulating abrasive, such as diamond particles, is embedded as shown in Figure 8.12. The rotating grinding wheel works as a cathode tool.

Applications of Electrochemical Grinding The single largest use for ECG is in the manufacturing and remanufacturing of turbine blades and vanes for aircraft turbine engines; Grinding of tungsten carbide tool inserts; Re-profiling worn locomotive traction motor gears; Burr-free sharpening of hypodermic needles
