Fully automatic honing and deglazing machine. New HON 2A!
Hon 2A restores slow-speed engine cylinder liner geometry and surface structure
Fully automatic honing & deglazing machine – HON 2A – for on-site honing of large 2-stroke cylinder liners is easily operated directly on the engine. With optional holding equipment, the honing machine can be used directly on liners, outside the engine. Honing rectifies the shape of the liner, removes scuffing and restores surface cross pattern.
HON 2A – machine features
- For liners 500 – 1000 mm bore
- Easy to operate directly on the engine
- Can be used directly on liners outside engine with optional fastening equipment
- Honing head with detachable stone holders
- System for continuous supply of honing liquid
- High honing capacity:
- powerful electric driving unit
- powerful electric hoist
- Adjustable stone pressure
- Fully automatic operation
- Preassembled rig:
- minimizes setup time
- makes setup even safer
- One rig fits all bore sizes
- Automatic stroke control included as standard

Why honing of cylinder liners?
The honing process rectifies longitudinal and circumferential surface geometry, thus restoring the cylinder liner’s oil retaining surface properties. Honing is vital to prolong the lifetime of cylinder liners and avoid running-in problems. If honing isn’t performed regularly there is a risk that the maximum wear limit provided by the engine makers won’t be reached before cylinder condition issues occur. Some common cylinder condition problems are broken piston rings and cylinder scuffing.
Honing results
The honing result depends on several process parameters such as honing speed, stone pressure, and number of strokes for each stage. Different types of stones are used throughout the process and up to five surface roughness parameters and several more geometrical parameters should be within a pre-specified range at the end of the honing process. This means that monitoring and controlling the process is challenging also for quite experienced users. Chris-Marine has therefore developed the Chris-Marine Honing App, a tool intended to make it easier to monitor and control the honing process, thereby improving quality while also saving time.
