In the world of precision manufacturing, CNC machining stands as a pinnacle of automation and accuracy, producing parts with tolerances once thought impossible. However, for components where the highest level of aesthetic appeal, tactile feel, and functional performance is required, the process is not complete with the last pass of the cutting tool. This is where the critical, humandriven art of hand finishing takes center stage, transforming a machined part into a premium product.

While CNC machines excel at geometry, they can leave behind subtle tool marks, sharp edges, or a specific, uniform surface texture. Hand finishing addresses these final details, bridging the gap between digital perfection and realworld application. Common techniques include:
Deburring: The meticulous removal of sharp edges or burrs left from machining, essential for safety, proper assembly, and preventing stress fractures.
Polishing and Buffing: Using progressively finer abrasives to achieve a mirrorlike or satin finish, crucial for medical devices, consumerfacing products, and parts requiring low friction.
Surface Blending: Skillfully smoothing out witness lines or minor imperfections between different machined surfaces to create a seamless, cosmetically flawless appearance.
Applying Specific Textures: Creating custom surface finishes like brush, bead blast, or orange peel effects that enhance grip or brand identity.
