Honing machine for restoration of medium speed engine cylinder liner geometry and surface structure.
Importance of Honing and Deglazing in Engine Overhauls
Many medium-speed engine makers recommend honing or deglazing during piston overhauls to prevent post-overhaul running issues. One of the key benefits of honing is reduced oil consumption, which is especially important in Otto-cycle gas engines. High oil consumption in these engines can lead to knocking problems, affecting performance. Honing Stones
For engines that are not worn but have glazed or polished cylinder liners—common when running on MGO, gas, or other low-sulfur fuels—deglazing is sufficient. This process refreshes the surface without altering cylinder geometry. However, when cylinder liners become worn, especially after a second piston overhaul in engines running on HFO, ovality and wear edges must be removed for optimal engine function. This more time-consuming process is called honing.
Choosing the Right Honing Stones
Honing time and stone consumption increase with larger cylinder diameters and stroke lengths. Diamond stones are more durable and remove material faster than ceramic stones, making them ideal for coarse honing of large or heavily worn engines. Conversely, ceramic stones provide excellent oil retention, making them essential for finishing the running surface structure.
Chris-Marine® offers a range of honing stones, rigorously tested and proven to deliver reliable performance for most engine types. Selecting the right stones ensures efficient engine maintenance and long-lasting results.
