Hi guys, in this article we are going to learn about the topic Electrochemical Honing Process along with its advantages, disadvantages, and industrial applications. It is an important topic in the subject of heat and mass transfer as well as advanced manufacturing processes.

Electrochemical Honing Process is a modern metal removal process in which both electrical energy and chemical energy are used together to remove material from the workpiece with high accuracy and better surface finish.

Electrochemical Honing Process its Advantages Disadvantages and Applications

In Electrochemical Honing process, the material is removed by combined action of electro chemical effect and conventional grinding effect. The set up for Operation is shows in fig.

The process uses rotating and reciprocating, non conducting bonded honing stones for removing material. The bonded abrasive stones are inserted in the slots provided on the stainless steel tool. A gap of about 0.075 to 0.125 mm is provided between the workpiece and the tool at the start of the operation. This gap increases upto 0.50 mm as material is removed from the surface of the workpiece.

Electrolyte at a pressure of upto 1.05 MPa is supplied between the tool and the workpiece through a number of small holes as shows in the fig. The bonded abrasive stones inserted in the slots are fed out with equal pressure in all directions so that their cutting faces are in contact with the surface of the workpiece. The workpiece is connected to positive terminal and tool to the negative terminal of a D.Cp power supply.

Most of the material is removed by the electrochemical action while grinding wheel provides a mechanical scrubbing action which removes a maximum of about ten percent material. 

 In this process we used hone tool. The process is extremely useful for honing of thin walled tubes and for deburring operations. 

Electrochemical Honing Process

Advantages 

1) Much faster material removal rate. The process is about 10 times faster than conventional honing.

2) Very little tool wear.

3) Pressure required between the stones and the workpiece is low.

4) High accuracy.

5) Burr free and stress free components are produced with negligible distortion.

6) Cost is low.

Disadvantages 

1) In this process cost of machines are high.

2) Only used for hard materials.

3) High initial cost.

4) Skill labours are required.

Applications

1) Electrochemical Honing Process used in deburring of gears.

2) For removing sharp edges.

3) Electrochemical Honing Process we use this process for the Good surface finish for hard material.

4) Grinding, Drilling, Trepanning and micro machining.

So in this article, we discussed the topic Electrochemical Honing Process along with its advantages, disadvantages, and applications. We hope this information helped you understand the concept in a simple and clear way.
