Precision Grinding for Modern Diesel Engines
Modern 2-stroke and 4-stroke diesel engines operate under extreme pressure and thermal stress. Therefore, sealing surfaces require highly accurate grinding to ensure tight sealing and long-term reliability. Moreover, using engine-tested CBN grinding wheels reduces wear, prevents leakage, and protects critical engine components.
Chris-Marine’s Proven Grinding Solutions
Chris-Marine offers CBN (Cubic Boron Nitride) grinding wheels that are carefully selected, tested, and proven for specific metal alloys, surface finishes, and workloads. Unlike generic grinding wheels, Chris-Marine CBN solutions deliver consistent cutting performance on hardened steel and high-tensile materials. As a result, workshops achieve predictable results and superior surface quality.
Optimized Abrasives and Bonding Systems
CBN is the second hardest abrasive material and excels in demanding engine maintenance tasks. Consequently, Chris-Marine combines CBN abrasives with optimized bond types, including resinoid, metallic, and electroplated bonds, to match each application precisely. This combination ensures controlled material removal, reduced heat generation, and extended wheel life compared to standard aluminium oxide or silicon carbide wheels.
A Professional Alternative to Standard Grinding Wheels
Compared with conventional grinding wheel manufacturers, Chris-Marine provides application-specific CBN wheels engineered for marine and power plant engines. Therefore, engine builders and service workshops rely on Chris-Marine as a high-performance alternative to non-specialized grinding solutions, especially for critical sealing surfaces.

Precision Coating Thickness Measurement with CTM
Chris-Marine’s Coating Thickness Measurement tool (CTM) delivers precise readings of coating thickness on both magnetic and non-magnetic base materials. This tool is essential for assessing the remaining lifetime of coated piston rings in 2-stroke engines. With a liner time scale of approximately 1000 Rh and a measurement time of just 15 minutes per liner, CTM provides fast, accurate results.
Key Benefits for Condition-Based Monitoring
CTM is designed for condition-based monitoring of piston rings, ensuring optimal engine performance. It measures non-magnetic coatings on magnetic materials, such as chromium-plated or plasma-coated cast iron, and non-magnetic coatings on non-magnetic materials, like plastic-coated stainless steel. The tool automatically detects the base material’s type, simplifying the process for users.
Compact, user-friendly and enables reliable measurements even in hard-to-reach areas. This makes it a practical choice for in-situ, non-destructive testing, contributing to more efficient maintenance planning.
The CTM combines ease of use with advanced technology, providing accurate measurements and helping optimize engine maintenance strategies.

High-Quality Honing Stones for Cylinder Liner Maintenance
Cylinder liners in 2-stroke and 4-stroke diesel engines operate under constant mechanical and thermal stress. Therefore, accurate honing becomes essential to maintain correct surface geometry and oil retention. Moreover, high-quality cylinder liner honing stones improve liner performance, reduce wear, and extend engine service life.
Proven Diamond and Ceramic Honing Stones
Chris-Marine offers diamond and ceramic honing stones that are carefully selected, tested, and proven across a wide range of marine and power plant engines. Unlike generic honing stones, Chris-Marine solutions deliver predictable material removal and consistent surface roughness. As a result, maintenance teams achieve repeatable results with minimal risk.
Optimized Honing Stone Sequence for Best Results
Successful honing depends on the correct combination of speed, stone pressure, and stroke count. Therefore, Chris-Marine recommends a proven three-step honing sequence. First, a diamond honing stone removes wear edges, glazing, and micro-seizures. Next, a rough ceramic stone eliminates smeared material and improves oil retention. Finally, a fine ceramic stone smooths surface peaks while preserving the liner’s oil-holding structure.
A Professional Alternative to Standard Honing Stones
Compared with conventional honing stone suppliers, Chris-Marine provides engine-specific honing solutions with multiple grain sizes and grades. Consequently, shipowners, engine builders, and service workshops choose Chris-Marine as a premium alternative to non-specialized honing tools.

Fast In-Situ Cylinder Liner Inspection
The Chris-Marine Liner Condition Camera (LCC) enables accurate cylinder liner condition monitoring without removing the cylinder cover or exhaust valve housing. Designed for 2-stroke engines with bore sizes from 480 to 980 mm, the LCC captures high-quality images of the entire liner wall and piston ring pack. As a result, engineers reduce inspection time significantly while improving documentation accuracy compared to traditional borescope inspections.
High-Resolution Imaging for Condition-Based Maintenance
Using the LCC, operators can precisely evaluate liner cleanliness, wear edge formation, honing marks, wave-cut groove extension, and corrosive wear. Moreover, the system clearly documents black lacquering and bore polishing, enabling early detection of abnormal wear. Consequently, maintenance decisions become faster, more reliable, and more cost-efficient than with competing liner condition camera.
Advanced Multi-Camera Technology
The LCC features four integrated cameras that together document the complete running surface. Cameras 1–3 capture slightly overlapping liner wall sectors, while Camera 4 inspects injectors and the exhaust valve area. Additionally, a tablet-mounted camera documents the piston ring pack and top land condition. Thanks to the laser-triggered LED flash system, the LCC collects only relevant images, thereby minimizing battery consumption and unnecessary data storage.
Time-Saving, Heat-Resistant, and Easy to Use
Unlike many alternative cylinder inspection tools, the LCC operates with high-temperature-resistant electronics and batteries, allowing inspections without lowering engine coolant temperature. Therefore, operators save valuable time during routine checks. Furthermore, only combustion chamber venting is required. On average, the system documents one cylinder in approximately 15 minutes, while a fully charged battery set supports up to 14 cylinders per session.

Fast and Accurate Cylinder Liner Measurements Onboard
The Chris-Marine Liner Diameter Measurement (LDM) system enables precise cylinder liner diameter measurements without removing the cylinder head or exhaust valve housing. Designed for 2-stroke engines with bore sizes from 500 to 980 mm, the LDM measures liner wear and clover-leaf deformation quickly and reliably. As a result, operators save significant time compared to traditional liner measurement methods.
Efficient Condition-Based Liner Maintenance
With the LDM, a single operator can measure one cylinder in approximately one hour, capturing up to 26 measurement levels. In contrast, conventional measurement techniques often require a three-person team and a full working day. Therefore, the LDM significantly reduces downtime, labor costs, and preparation time, making it an efficient alternative to other liner wear measurement tools.
Detect Abnormal Wear and Clover Leafing Early
The LDM accurately identifies non-oval liner wear, including clover leafing caused by slow steaming retrofits, injector erosion, and uneven lubrication. Consequently, engineers can implement corrective actions before damage escalates. Moreover, the system supports continuous liner wear monitoring, ideal for dock preparation and condition-based maintenance strategies. Compared with competing liner measurement systems, the LDM delivers higher accuracy and faster diagnostics.
User-Friendly Design for Onboard and Workshop Use
Chris-Marine offers the LDM in both an easy-to-use onboard version and a workshop version with a rugged case, micrometer set, and calibration rig. In addition, the handheld tablet interface provides remote technical support and software updates. The latest generation also delivers up to 13 hours of continuous operation, further improving usability. The LDM supports MAN B&W, Wärtsilä, and Mitsubishi 2-stroke engines, offering broad compatibility unmatched by many alternative brands.
