Wet / Vapour Honing Machine for Two-Wheeler Crank Pins
Overview
Crank pins are high-precision components used in the connecting rod bearing arrangement at the big-end position of 2-stroke and 4-stroke engines. Their surface finish plays a critical role in ensuring smooth operation, proper lubrication, and reliable engine performance.
The crank pins require a controlled surface finish of 0.8 to 3.0 Ra on both end portions, while the middle portion needs to be masked to prevent abrasive media from entering the lubricating hole.
With extensive experience in developing surface finishing solutions for the automotive industry, MEC SHOT designed, manufactured, and supplied a Semi-Automatic Wet / Vapour Honing Machine specifically for crank pins. The machine provides controlled and consistent honing of both end portions while protecting critical areas during the process.
