We share information and tips we’ve learned from our experience in the CNC machining and sheet metal fabrication industry.
Oxidize brass antiquing methods create a controlled aged surface on brass by darkening the outer copper-rich layer and, when needed, polishing high points back to a warm metallic highlight. For CNC machined brass parts, this finish is more than a decorative color. It affects how grooves, threads, engraving, edges, knurled areas, and flat machined faces […]
Brass parts are often selected for CNC machining because they cut cleanly, hold fine details, and provide a warm metallic appearance. However, a freshly machined brass surface can show tool marks, handling stains, burr traces, and directional cutting lines. Brass sandblasting is used when engineers need a more uniform matte texture without changing the part […]
Aluminum corrosion removal is not simply a matter of making a metal surface look brighter. The cleaning method must distinguish harmless natural oxide from active attack, remove contamination without excessive etching, protect dimensional features, and prepare the part for service or a new finish. This guide explains how corrosion develops on aluminum parts, how to […]
Chrome plating may need to be removed when it peels, pits, cracks, looks uneven, hides corrosion, or makes a precision feature oversize. For CNC machined parts, removal is not merely a cleaning task. The coating may be part of the final diameter, surface roughness, wear system, or sealing function. A successful repair must remove the […]
Sandblasting is a mechanical surface treatment that propels abrasive particles toward a part at controlled speed. On CNC machined components, it is commonly selected to remove light oxidation, reduce visible tool marks, create a uniform matte texture, or prepare a surface for a later coating. The process appears simple, but the final result depends on […]
Polished titanium is produced by progressively removing machining marks and microscopic peaks until the surface becomes smoother and more reflective. It is used on visible CNC components, cleanable parts, low-friction contact areas, and products where a refined metallic appearance matters. However, polishing is not only cosmetic. It removes material, can soften edges, exposes defects left […]
