What is honing
Honing is done after the liner has been glazed and has lost its rough surface. A rough surface is essential to maintain the lubricating oil film so that there is a film between the piston rings and the liner to decrease friction and wear on both the rings and the cylinder liner. Honing provides precision in bore geometry, size control, surface quality, and surface structuring.
The honing procedure provides the final size and finishes the inside tube or cylinder bores. Finishing is achieved by rubbing abrasive stones of the appropriate grit and grade against the work surface. We are combining rotation with reciprocation resulting in a crosshatch pattern on the surface of the sharpened item.
Honing is a popular and commonly used method of cylinder liner surface finishing. By brushing an abrasive stone against it along a particular route, the honing process generates a precision surface within the surface of a cylinder liner. Honing is usually used to enhance the surface's geometry and texture.
Why Honing Necessary
The engine's mechanical power loss accounts for about 16% of overall energy losses, with friction in the piston-liner accounting for half of this loss. The liner surface topography may limit oil consumption with undesirable combustion products. It also helps to minimize oil slobber.
Why Is Cylinder Liner Honing?
Honing is a machining operation that is used to polish interior cylindrical surfaces. A high percentage contact area of the cylinder liner is necessary to decrease engine oil consumption and running-in wear. You can alter the shape in basic honing valleys to reduce wear and scuffing.
What Is Honing Of Cylinder Liners?
The advantage of cylinder liner honing is to remove any ovality, deformations, or scratches from the cylinder liner wall. Create a mesh of varying depths in the material to enable the cylinder lube oil to stay in the mesh grooves for improved lubrication.
Honing Angle & Surface Texture
In conventional plateauing, the honing angle and texture must be kept straight. Slide honing might result in a perfect plateau on the liner surface. Diagonal or helical sharpening is a more uniform method.
Honing tool:
- Machine for Honing
The honing procedure, honing angle, defined depth of honing, bore diameter, stroke length, and other factors all influence the choice of honing machine. The engine cylinder liner manufacturers in India's recommendations should choose it.
- Honing Stones
Diamond abrasive stones are often utilized. However, a SiC ceramic honing stone is employed for a smoother liner surface.
- Honing Procedure
Choose a honing machine and stones based on the engine's cylinder liner manufacturers in India.
Honing stone connected to jaw -Install honing machine and set reciprocating motion -stroke length, Stroke per minute, rotating motion-rpm, and surface pressure of revolving jaws.
The finishing of the cylinder liner surface produces a crisscross patterned topography consisting of a series of honing valleys of varying density, peak radii, depths, and widths related to selected machining parameters and honing tool composition grain size, grain material, binding material, and grain density.
