2026 08 05 Stainless steel watch case polishing normally includes pre-finish inspection, deburring, progressive grinding, rough polishing, intermediate polishing, fine or mirror buffing, cleaning, and dimensional and cosmetic inspection. Mixed finishes require defined brushing direction, masking, protected edges, and an approved master sample to maintain consistency.

VMT 2026 08 05 Common CNC watch case machining problems include thin-wall deformation, tolerance stack-up, datum shift, incorrect crystal or bezel fits, thread defects, gasket-groove burrs, misaligned side holes, chatter, polishing loss, coating buildup, color inconsistency, and batch variation. Most can be reduced through DFM, staged machining, stable workholding, in-process inspection, and approved finish standards.

VMT 2026 08 03 Electrophoretic coating (commonly known as E-coating or electrocoating) is a high-performance surface treatment for custom machined aluminum parts. It is a method of applying a protective or decorative coating to a metal object (which must be electrically conductive) through an electrochemical process. The important thing is that the E-coating is used to provide corrosion resistance, enhance aesthetics, and improve the durability of metal parts.
