The electrochemical process will not only remove imperfections on the surface after welding – but it will also restore the oxide layer that returns stainless steel back to its normal passive state. Unlike grinding, this cleaning method will successfully remove all dirt and discoloration from the welds.

ECG combines abrasive grinding with electrochemical machining to provide stress-free, low force, and burr-free cuts. Used extensively for medical and aerospace applications to cut high-temperature alloys, stainless-steels, and materials that are difficult to machine. Typical applications include needles, fasteners, and tube cutoff.
Park et al. recently reported a composite anode of Si nanoparticles and 2D porous conductive Ni 3 (2,3,6,7,10,11-hexaiminotriphenylene) 2 MOF (Si/Ni 3 (HITP) 2) prepared by grinding the mixture of the pre-synthesized Si and Ni 3 (HITP) 2 materials together .
Putting Technology to Work Electro Hydraulic Machinery builds custom industrial equipment for the heavy civil infrastructure market using the latest technologies available. We take standard industrial components and meld them into reliable working systems. Electrical, Hydraulic, and Mechanical equipment are the three pillars of all modern industrial machinery.
Owing to the electrolytic reaction, ECG eliminates the need for a separate deburring operation. It is also a low stress machining operation that avoids potential metallurgical damage associated with conventional grinding machines, including cracking and heat distortion. This makes ECG ideal for machining of delicate and thin walled parts.

In mechanical machining processes such as cutting, milling and grinding, undesired cracks or fractures are frequently generated on the machined surface of brittle materials. Thus, avoidance or even just reduction of undesired cracks or fractures on machined surfaces is a challenging problem ( Mostofa et al., 2013 ).
What is Electrochemical Grinding and How it's done. Electrochemical grinding is a process that removes electrically conductive material by grinding with a negatively charged abrasive grinding wheel, an electrolyte fluid, and a positively charged workpiece. Materials removed from the workpiece stay in the electrolyte fluid. get price
