At iB, we perform true surface grinding using grinding stones instead of milling with cutting tools for cylinder surfaces. This results in significantly higher surface smoothness and flatness, allowing us...

Plateau Honing process

Plateau Honing process

We hone the ultra-hard plated inner diameter using diamond grinding stones, as regular grinding stones are ineffective. This process creates deep oil grooves that serve as oil reservoirs. After that,...

Shrink-fit the aluminum-plated sleeve

Shrink-fit the aluminum-plated sleeve

We heat the cylinder barrel while monitoring its temperature with a contact thermometer, then shrink-fit the aluminum-plated sleeve on the press. Once it cools, you can’t adjust its position, so...

Plated stock H2 sleeves

Plated stock H2 sleeves

These are the plated stock sleeves that will be press-fitted into the cylinder barrels. You can see the intake, scavenging, and exhaust ports. They are bridged ports.
