Electrochemical cutting is a balance between unsupported grinding action and electrochemical erosion. Why? 1 ECH is widely used in power generation amd powerchemical industries.2 It is used in gear teeth error correction.3 It is used in increasing life span of the roller , gears, sleeves, dies, gears and internal cylinders.4 It is also used in processing different materials like carbide, titanium, alloys, Inconel Incoloy, Titanium alloys, etc. Machine capacities are currently able to accommodate bore lengths up to 600 mm and bore diameters from 9.5 to 150 mm. Power consumption is very high. If you have any query regarding this article, ask by commenting. At the beginning of the ECH cycle, the stones protrude only 0.075-0.127mm from the stainless steel body, establishing the gap through which the electrolyte flows, The electrolyte enters the tool body via a sliding inlet sleeve from which it exits into the tool-workpiece gap through small holes in the tool body, After passing through the gap, the electrolyte flows from the workpiece through the gap at the top and bottom of the bore, The mechanical action of the tool is the same as with conventional honing; the tool is rotated and reciprocated so that the stones abrade the entire length of the bore, Electrolytes used in ECH are essentially the same as those used in ECM, although the control of pH, composition and sludge is less critical because the abrasive action of the stones tends to correct any resulting surface irregularities. The advantages of corrosion testing and failure analysis. The detector design with the electronics can be simple and compact, allowing the construction of portable instruments, especially when conductometric, potentiometric, and amperometric detection is used. For example, while our double-disk grinding is often the final step in manufacturing, Metal Cutting can add … The greatest advantages are that all work is completely free of burrs.

LearnMech.Com is a Mechanical Project-oriented platform run by Sachin Thorat who is a B-Tech Graduate in Mechanical Engineering. The tool does not wear. Designing and marking of the tool is difficult but its life is long so recommended only for mass production. Tool consists of a hollow stainless steel body that has expandable, nonconductive honing stones protruding from at least three locations around the circumference, The honing stones are identical with those used in conventional honing operations, except that they must resist the corrosiveness of the electrolyte, The honing stones are mounted on the tool body with a spring-loaded mechanism so that each of the stones exerts equal pressure against the workpiece. Advantages of electrochemical machining: The rate of machining does not depend on the hardnessof the work piece material. As in ECM, the electrolytes are recirculated and reused after passing through appropriate filtration, and the most commonly used electrolytes are sodium chloride and sodium nitrate.
