Enhance your industrial surfaces quality control with this Rustfree Roughness Comparison Sample made from premium nickel alloy and high carbon chromium bearing steel. Designed specifically for lathe machining, flat milling, turning, planing, and filing, this comparator facilitates efficient and accurate evaluation of surfaces roughness on batch workpieces.
This tool allows sampling and screening during production, helping to quickly identify defective surfaces finishes without requiring on-site assembly or maintenance of delicate measuring instruments. It streamlines quality control workflows by providing a reliable and standardized reference that bridges communication between suppliers and buyers, minimizing disputes arising from surfaces roughness variations.
for use in training environments, this roughness sample aids technicians and operators in understanding and differentiating roughness parameters, improving workmanship and process control. Additionally, it is an invaluable resource for pre-treatment inspection, verifying that workpieces meet the strict finish criteria before undergoing electroplating, spraying, or other surfaces treatment processes.
Constructed from rust-resistant nickel alloy and high carbon chromium steel, this sample ensures long-lasting use even in demanding industrial environments, maintaining consistent accuracy over time.

Features:
* For quality sampling of batch workpieces in industrial production, efficient screening of roughness defective products.
* Quickly judge the adaptability of parts in the absence of on-site installation and maintenance scenarios of for instruments.
* Unify standards for acceptance by both supply and demand parties to reduce disputes caused by detection differences.
* Help understand the state corresponding to different roughness parameters in teaching and training.
* Before spraying, electroplating and other processes, assist in judging whether the workpiece meets the pretreatment requirements.
