TL;DR: A diamond grinding layer, particularly suitable for honing segments comprising a porous metal carrier, a binding metal filling at least partially the pores of said carrier and diamond grinding grains, the metal carrier being composed of hard metal powder, a bonding metal powder and non metallic destruction particles as mentioned in this paper.
Abstract: A diamond grinding layer, particularly suitable for honing segments comprising a porous metal carrier, a binding metal filling at least partially the pores of said carrier and diamond grinding grains, the metal carrier being composed of hard metal powder, a bonding metal powder and non metallic destruction particles, the metal carrier having wear properties substantially the same as the diamond grinding grains.

TL;DR: In this article, the cutting direction angle of 40°∼50° is the most suitable for fine-grained abrasive stones and the cutting speed of 40 m/min is the best.
Abstract: For the purpose of inquiring into the cutting mechanism of fine-grain abrasive stones in the honing, an experimental research has been carried out with an external honing apparatus. Concerning the cutting speed, the best cutting efficiency is obtained at a cutting speed of 40 m/min. The cutting direction angle of 40°∼50°is the most suitable, and the cutting direction angle is the most decisive factor in the cutting mechanism of honing. As to the bond hardness, it is suitable to use the harder stone. Comparing the honing with the superfinish, the most suitable values of cutting direction angle and cutting speed are same in both cases. But the cutting efficiency of superfinish is 5∼10 times that of honing, and the stone wear per unit amount of stock removal of honing is slightly smaller than that of superfinish.

TL;DR: In this article, five different honing patterns on a cast iron liner and one on a spray-coated aluminum liner are studied with a floating liner engine and numerical models, and the results show that the roughness height and structure of the honing affect the twin-land oil control rings lubrication differently.
Abstract: Engine bores are finished with a multi-stage honing process and the finished surface roughness contributes significantly to the piston ring hydrodynamic pressure generation, especially for twin-land oil control rings whose land profile is parallel to the liner surface. In this paper, five different honing patterns on a cast iron liner and one on a spray-coated aluminum liner are studied with a floating liner engine and numerical models. The liner temperature and engine speed were varied such that all the lubrication regimes, namely boundary, mixed, and fully hydrodynamic, are present. It is found that the models based on deterministic approach with a patch of carefully measured liner roughness can match the trend of the Stribeck curves for different liner finishes observed in the experiment. Furthermore, the results show that the roughness height and structure of the honing affect the twin-land oil control rings lubrication differently. With the same honing structure, although rougher liner experiences mi...

TL;DR: The results show that the dominant frequency in the power spectrum is very sensitive to honing tool conditions and a good correlation exists with honed surface quality, therefore, AE signals can be used for ascertaining the Honing tool performance and establishing the end of tool life.
Abstract: Sensing Acoustic Emission (AE) signals from a machining process is one of the most promising methods suitable for tool condition monitoring because of its sensitivity combined with quick and high frequency response. In this work, AE signals are monitored during rough, finish and plateau honing of cylinder liner using fresh and completely worn out honing tools. AE parameters such as Root Mean Square (RMS), peak to peak, skewness and kurtosis and dominant frequency in the power spectrum are analysed. The results show that the dominant frequency in the power spectrum is very sensitive to honing tool conditions and a good correlation exists with honed surface quality. Therefore, AE signals can be used for ascertaining the honing tool performance and establishing the end of tool life.

TL;DR: In this article, an improved version of an improved honing machine was proposed for finishing the interior walls of cylinders having one end closed or obstructed, such as the so-called blind end cylinders of radial aircraft motors.
Abstract: This invention relates to an improved honing machine and in particular to a machine of this character for finishing the interior walls of cylinders having one end closed or obstructed, such, for example, as the so-called blind end cylinders of radial aircraft motors. Where during the honing...
