Checks

Definition

Checks are small slits running parallel to the grain of wood, caused primarily by strains produced during seasoning and drying, but they can also result from incorrect speeds and pressure contact points.

Purpose

The purpose of identifying checks is to recognize and address these imperfections, which can affect the structural integrity and appearance of wood products. Proper handling and treatment can minimize checks.

Examples of Use

1. Lumber Grading: Inspecting boards for checks to determine their suitability for construction or finishing.
2. Furniture Production: Detecting checks in wood used for high-quality furniture to ensure a smooth, flawless finish.
3. Wood Flooring: Checking hardwood planks for checks that could affect durability and aesthetics.

Related Terms

• Cracks: Larger and deeper separations in wood fibers compared to checks.
• Splits: Severe forms of checks where the wood fibers have completely separated.
• Warping: Distortion in wood shape, often occurring alongside checks due to uneven drying.

Notes

• Checks are often a result of the natural drying process but can be minimized through controlled seasoning.
• Proper machining techniques and speeds are crucial to avoid inducing additional checks during processing.
