What is electrochemical honing?

What is electrochemical honing?

Electrochemical Honing is a process in which material is removed with help of electrical energy, chemical energy and honing process. For those who don’t know, 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.

What are the disadvantages of honing?

Disadvantages of Honing Process: The roughness of Abrasive stones gets decreased easily in the case of honing process. Straightness of the hole: The honing process only improves the inner surface quality of a hole or a bore. It does not improve the straightness of the hole.

What is the advantage of ECH over conventional honing process?

ECH can remove materials at rates up to 100% faster than conventional honing, the gain being more pronounced as the material hardness increases. Machine capacities are currently able to accommodate bore lengths up to 600 mm and bore diameters from 9.5 to 150 mm.

Why is electrochemical process found to be the most potential process for gear finishing?

Electrochemical honing (ECH) has capabilities and potential to be developed as an alternative of conventional gear finishing processes and can play an important role as high-precision gear finishing method because being a hybrid machining process it has potential to overcome most the limitations of conventional gear …

What is honing process PDF?

Honing is a process that is performed on a job to make it proper size by removing marks and roughness left on a job by the cutting tools. The Honing machine is used to make internal combustion engines, air-bearing spindles, finishing of cylinders and gears.

What is the honing process?

Honing is a cutting process with bonded grain and is used to improve the form, dimensional precision, and surface quality of a workpiece under constant surface contact with the tool. In general, honing is applied after precision machining (e.g., grinding).

What is the process of honing?

What is electrochemical deburring?

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 a precise. manner.

Why gear finishing is required?

To achieve the strength, wear properties and other characteristics these diverse and numerous applications call for, engineers created unique finishing processes which hone and treat the surface of a gear. These processes are the crucial final step in gear fabrication.

What are the various method used for gear finishing?

The conventional gear finishing processes described are grinding, lapping, honing, shaving, burnishing while advanced gear finishing process include abrasive flow machining (AFM).

What are the types of honing?

There are three basic types: flexible hones, hand hones, and honing sticks or tools.

What is the function of honing?

Honing is an abrasive machining process that produces a precision surface on a metal workpiece by scrubbing an abrasive grinding stone or grinding wheel against it along a controlled path. Honing is primarily used to improve the geometric form of a surface, but can also improve the surface finish.
