mill finish การใช้

• Other mill finishes are surprisingly smooth and uniform.
• One advantage is that the treatment disguises surface markings on bright mill finish copper and can advance the natural patination process.
• The quality and characteristics of mill finish can vary widely from one mill to another, and even from one lot ( set of similar parts all processed consecutively or in a short time ) to another . hot worked.
• Mill finishes are derived by normal production processes, such as rolling, extrusion, or casting . " Buffeted " finishes impart bright mirror-like appearances after grinding, polishing, and buffing . " Directional textured " finishes provide a smooth, velvety satin sheen in a continuous pattern of fine nearly parallel scratches . " Non-directional textured matte " finishes achieve a rough texture, primarily on castings, as spray sand or metal shot are applied under high pressure.
