Lihvimisplaati

Lihvimisplaati is a term used in Finnish to describe a flat, rigid plate that serves as a support surface in sharpening and lapping processes. The plate provides a stable, smooth base for abrasives or abrasive-coated surfaces, helping to achieve a controlled contact area and consistent results.

Materials and variants vary. Plates can be made from natural stones, ceramics, metals, or polymers. They may have a fixed abrasive surface or be used with detachable abrasive sheets, films, or pastes. In some setups, a separate abrasive slurry or liquid is used during operation to improve the sharpening or finishing action.

Use and applications. Lihvimisplaati is employed in blade maintenance, metalworking, and manufacturing for sharpening knives, chisels, razors, and tools, as well as for lapping and finishing flat surfaces. It can be used with oilstones, waterstones, grinding films, or diamond pastes. Operators typically secure the workpiece, maintain an appropriate edge angle, and use even strokes while controlling pressure and lubrication for a consistent finish.

Operation and maintenance. Regular cleaning and drying after use help prevent corrosion and glazing. The plate’s surface should be kept flat; worn or grooved plates may require resurfacing or replacement. Some systems include a method to flatten the plate periodically to restore true flatness.

Safety considerations. Use eye and hand protection, clamp or secure workpieces, and avoid overheating the material being sharpened. Work in a well-ventilated or appropriately ventilated area when using oils or pastes.
