ELECTRO CHEMICAL HONING INTRODUCTION Electrochemical honing (ECH) combines the high removal characteristics of ECD and MA of conventional honing. The process has much higher removal rates than either conventional honing or internal cylindrical grinding. In ECH the cathodic tool is similar to the conventional
Honing is an abrasive machining process that produces a precision surface on a metal workpiece by scrubbing an abrasive stone against it along a controlled path. Honing is primarily used to improve the geometric form of a surface, but may also improve the surface texture .
Electro Chemical Honing Electrochemical honing (ECH) is a hybrid electrolytic micro finishing technology characterized by a distinct coupling of electrochemical machining (ECM) and conventional mechanical honing (MH) processes to provide controlled functional surface generation and fast material removal capabilities in a single operation.
Electrochemical Honing • It is a process in which it combines the high removal characteristics of Electrochemical Dissolution(ECD) and Mechanical Abrasion(MA) of conventional Honing. • It has much higher rates than either of honing & internal cylindrical grinding.
Electro-Chemical Machining (ECM) is the generic term for a variety of electro-chemical processes. ECM is used to machine workpieces through the anodic dissoultion of metal. The process is used in aerospace engineering and the automotive, construction, medical equipment, microsystem and power supply industries.

Process kinematics today. The work process with honing is a combination of stroke and rotation movement of an expandable honing tool with inserted honing stones or diamond sticks. The result is the surface structure with cross-hatch pattern generated by the honing process.
mathematical modeling of an abrasive electrochemical grinding (AECG) process. In AECG a metal-bonded grinding wheel is used instead of a graphite or metal wheel-electrode used in electrochemical grinding (ECG). Therefore, the mechanical abrasion is combined with the electrochemical dissolution.
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.

The honing gear “2” which is also a bevel gear is mounted at the backside of the workpiece gear in such a way that the axes of rotation of honing gear, workpiece gear, and complimentary cathode gears are mutually perpendicular to each other, while axes of rotation of cathode gears and honing gear are coplanar. Workpiece and honing gears ...
Electrochemical deburring is a method that finishes the workpiece surfaces by means of anodic metal dissolution. The deburring tool is the cathode (-) that acts under DC current and in the presence of an electrolyte fluid to create the anodic reaction that removes workpiece (+) surface material in …
The ElectroChemical Grinding (ECG) process does not leave the typical shiny finish of abrasive grinding. This is because there is no smearing of the metal as in conventional grinding. A 16 micro inch finish or better can be achieved but it will have a matte (dull) rather than a polished look. ... Everite Machine Products. 1555 Route 73 South ...
