sandingis

Sandingis is a term used in the field of surface finishing to describe a structured approach to material abrasion intended to produce a defined surface roughness and surface integrity prior to coating, bonding, or further processing. It integrates selection of abrasives, methods of application, and verification of surface quality into a cohesive protocol. While not universally standardized, sandingis is used by practitioners to emphasize repeatability and traceability in surface preparation.

Typical practice involves selecting abrasive media (for example aluminum oxide, silicon carbide, or ceramic abrasives) and an appropriate grit range, then applying controlled motion and pressure. Tools can be manual, such as sanding blocks, or machine-based, including belt sanders and orbital or random-orbit machines. The process aims to remove material efficiently while minimizing heat buildup, edge damage, and clogging of the abrasive.

Process parameters—pressure, speed, feed rate, and number of passes—are adjusted to achieve the target roughness, commonly expressed as Ra, and to preserve substrate integrity. Surface quality is often verified with profilometry, tactile roughness measurements, or visual inspection for scratches and fiber lift in composites.

Applications span woodworking, metal fabrication, automotive refinishing, and composite manufacturing, where proper surface preparation improves coating adhesion and durability.

History and terminology: The term arises in industrial finishing discourse and is used variably across fields; some practitioners treat sandingis as a subset of standard sanding protocols, while others regard it as its own framework for quality control.
