Electrochemical Grinding: Working, Application,

The current applied is in the range of 50 to 3000 A at 4 to 10 V (250 A/cm) Read also: Ultrasonic Machining (USM): Parts, Working Principle, Advantages, Application and More Accuracy: Because there is very little abrasive action, Electrochemical grinding does not leave fine scratches which may impair the finish and leave stress raisers ECG Grinding includes: BurrFree, Fast Metal Removal; Plunge Grind 4” (100mm) Wide Batch; Precise Servo Controlled Platen for Needle Rotation; Point Geometry Easily Changed in Program; Low Wheel Wear; No Grit Blast Required; Quick Changeover from 27 Gage to 8 Gage; Any Number of Point Facets; Easily grind almost any point geometryElectrochemical Grinding (ECG) Cadence Inc For those interested, the grinding wheel has a rotation speed that is maintained between a maximum of 2000 m/min and a minimum of 1200 m/min Why Use Electrochemical Grinding? ECG offers several attractive process features including the following: Wide processing range and strong adaptability; Good economy and small wear loss of grinding What You Need To Know About Electrochemical

New Applications for Electrochemical Grinding

According to Travia, G ratios (the ratio of how much metal is removed to how much wheel is consumed in doing so) of traditional grinding applications are usually 1 or less than 1, while G ratios for ECG applications can range The grinding wheels Tridex uses range in size from 0004 to 40 inches wide These standard wheels will work for most applications, although workpiece materials such as copper or titanium will require wheels made for these materials Electrolyte fluid is an important part of the ECG processNew Applications for Electrochemical Grinding The investigation demonstrates that enough fast conversion reaction tends to reduce the crystallite size of αFe 2 O 3 significantly as a result of the electrochemical grinding and the continuous cycling can generate the FeFeFe mediumrange ordering terminated by long FeO bonds, which exploits a facile conversion reaction route catalyzing the dissociation of Li 2 O toward lower redox potential and faster Electrochemical grindinginduced metallic assembly

The abrasive particles of the grinding wheel make a contact with the workpiece and the gap between the wheel and workpiece makes passage for electrolyte circulation The gap voltages range from 25V to 14V The electrochemical reaction takes place between the anodic (+) workpiece and cathodic () grinding wheel and metal starts to remove from the workpiece Advantages It is time to throw lights on the advantages of the electrochemical grinding: The main advantage of this process is that it takes place in a very short span of timeWhat is Electrochemical Grinding and How it Works Our latest Electrochemical Grinding (ECG) equipment is high precision, burrfree grinding machinery with controllable heal rounding for noncoring, and the ability to machine hard material such as spring temper, profile grinding shavers, etcElectrochemical Grinding (ECG) Cadence Inc

What You Need To Know About Electrochemical

A Closer Look at ECG (Electrochemical Grinding) In comparison to electrochemical machining, electrochemical grinding is relatively similar Basically, it is a combination of an electrochemical process and a grinding process used for metal removal You may also hear it referred to as “anodic machining” or “electrolytic grinding” (4) Strong adaptability and wide processing range Electrochemical grinding can process all kinds of difficulttomachine conductive thermal spray coatings and all types of surfaces (such as gear surface) In short, electrochemical grinding is a processing method of high productivity, good processing quality and economicProcessing of Thermal SprayElectrochemical Grinding The grinding wheels Tridex uses range in size from 0004 to 40 inches wide These standard wheels will work for most applications, although workpiece materials such as copper or titanium will require wheels made for these materialsNew Applications for Electrochemical Grinding
