Comprehensive Solutions
Chris-Marine offers complete solutions for diesel and gas engine maintenance, designed to minimize downtime and reduce costs. Our extensive Grinding & Machining portfolio is developed to overhaul and restore cylinder heads, liners, and sealing surfaces with precision.
Advanced Automatic Honing Machine for Medium-Speed Engines
The Chris-Marine HON A Automatic Honing Machine restores cylinder liner geometry and surface structure on medium-speed diesel engines. Therefore, it helps maintenance teams achieve correct liner profiles and optimal oil retention. Moreover, the electrically driven system operates with less noise than pneumatic alternatives, improving working conditions onboard and in workshops.
Programmable Control for Accurate Cross-Pattern Angles
HON A features automatic stroke control and a programmable handheld PLC controller. Consequently, operators can set and maintain an exact liner cross-pattern angle throughout the honing process. Speed, stroke length, and honing stone pressure remain adjustable during operation, which ensures flexibility and precision at every stage.
Safe, Efficient, and Compatible Honing Operations
The synchronized vertical and rotational movements deliver consistent material removal, while built-in safety limits prevent the honing head from exceeding set turning points. Additionally, HON A works seamlessly with existing Chris-Marine HON S and HON S2 honing heads, allowing easy upgrades without replacing core components.
A Professional Alternative to Pneumatic Honing Machines
Compared with compressed-air honing machines from other brands, HON A delivers lower noise levels, higher accuracy, and automated control. Optional features such as a patented chain slack detector, vibration dampers, and a solid honing cage further enhance safety, productivity, and liner surface quality. Therefore, HON A stands out as a premium alternative to conventional honing solutions.

Flexible Honing Directly on the Engine
The Chris-Marine HON S is a portable pneumatic cylinder liner honing machine designed for efficient on-site use. Therefore, maintenance teams can hone liners directly on the engine or in a honing rig without dismantling major components. Moreover, the system supports liner bores from 150 to 670 mm, making it suitable for a wide range of 2-stroke and 4-stroke diesel engines.
Accurate Honing for Restored Liner Geometry
HON S restores liner shape, removes scuffing, and re-establishes the correct surface cross-pattern. Consequently, piston rings achieve improved oil retention and reduced wear. Variable hoisting speed and exchangeable gearboxes allow operators to fine-tune the cross-angle pattern and honing capacity for each application. pneumatic honing machine
Safe, User-Friendly, and Fully Pneumatic
The machine operates fully on compressed air, although an electric drive unit is available on request. Additionally, the redesigned external control box places speed, stone pressure, reset, and emergency controls in one location, improving safety and ease of use. Automatic stroke control further ensures consistent results throughout the honing process.
A Proven Alternative to Conventional Honing Machines
Compared with standard portable honing machines, HON S offers patented safety features, including an optional chain slack detector and vibration dampers that reduce head wear and liner surface patterns. Optional upgrades such as 8-armed honing heads and a torque wrench kit improve accuracy and productivity. Therefore, HON S stands out as a reliable alternative to generic honing equipment from other manufacturers.
