Manufacturing Technology Honing Honing is a finishing process performed by a honing tool, which contains a set of three to a dozen and more bonded abrasive sticks. The sticks are equally spaced about the periphery of the honing tool. They are held against the work surface with controlled light pressure, usually exercised by small springs.
The future of manufacturing companies depends largely on their ability to adapt to swiftly changing global conditions. These are exemplified by international competition, rapidly growing intercommunication and the increased significance of
Mar 21, 2016· Gear honing is a particularly effective method of removing nicks and burrs from the active profiles of the teeth after heat treatment. Combined with its ability to improve surface finish and make minor form corrections, the honing process is rapidly being accepted as a technique for surface finishing of gears after the heat treatment process.
1. Electrochemical honing (ECH) is a hybrid process of ECM and mechanical honing and is used in finishing of complex shaped products, such as helical and bevel gears, external and internal cylindrical surfaces. 21 Fig :Proposed process principle of Ultrasonic ECH of bevel gear.[8] Fig : Schematic view of the ECH setup used for finishing of ...
The honing process provides the final sizing and creates the desired finish pattern on the interior of tubing or cylinder bores. Finishing is accomplished by expanding abrasive stones of suitable grit and grade against the work surface. The stones are rotated and reciprocated in the part with hone abrasive under controlled pressure.

Traditional honing technology is widely used for the cast iron cylinder liner [18] [19] [20], it is by means of the oilstone embedded in the honing head to process the surface, but it may not be ...
process that can create the demanded surface texture as well as the crosshatch pattern needed in cylinder liners [6]. During the honing process a tool called honing head, which is equipped with abrasive stones, is moved through the cylinder bore. The head is subject to a rotational and reciprocal speed throughout the operation.
Dec 20, 2019· 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. In honing a hone tool is used

Honing Honing is a low abrading process Used to improve the surface finish of holes Stock removing from metallic and non-metallic surfaces Tool has a reciprocating axial motion and produces a crosshatched pattern on the surface of the hole In this process bonded abrasive sticks/abrasive stone is used The dimension to an accuracy of 0.005
Nov 19, 2009· Introduction. Honing is a machining process for finishing internal cylindrical surfaces. In order to reduce engine oil consumption and running-in wear a high percentage contact area of cylinder liner is required. It can be done by reducing the depth of the base honing valleys (slide honing).
Honing is a finishing process, in which a tool called hone carries out a combined rotary and reciprocating motion while the workpiece does not perform any working motion. Most honing is done on an internal cylindrical surfaces, such as automobile cylindrical walls. The honing stones are held against the workpiece with controlled light pressure.

Honing and Stropping Honing-is the process of removing gross nicks on the knife edges. This procedure use a natural sharpening stone and it is called "Hone" Types of hone: • Belgium Yellow - this is use when the knife cutting edges is blunt or nicked. • Arkansas - this gives the knife more polishing effect. • Fine carborundum - this hone is use only for badly nicked knives.
Apr 13, 2012· Multi-stroke honing is the more flexible and capable process because it uses "smart" tooling under servo control. The reciprocating abrasive tool with expanding stone assemblies can be controlled in size with accuracy of 0.000001 inch. Feed force of the abrasive can also be servo controlled.
Honing Machine. The honing process provides the final sizing and creates the desired finish pattern on the interior of tubing or cylinder bores. Finishing is accomplished by expanding abrasive stones of suitable grit and grade against the work surface. The stones are rotated and reciprocated in the part with hone abrasive under controlled pressure.
Feb 03, 2021· Honing. (i) In honing process internal cylindrical surfaces are preferred for a smooth finish. (ii) Grind or fine machine is done. (iii) It is less fine than lapping. (iv) Up to IT 4 tolerance grade can be obtained in this process. (v) Sliding is suitable for surfaces.
