Industry Context & Processing Challenges: Modern smartphone middle frames and casings are machined from solid billets of anodized aluminum (6063/7075), stainless steel (316L), or Grade 5 titanium. High-speed 3D contour milling, micro-hole drilling (∅<0.5 mm), and bevel chamfering require high spindle speeds (>30,000 RPM) without thermal distortion or micro-burr formation.
Technical Requirements: High-gloss bevel surface roughness Ra<0.1 μm, strict profile tolerance within ±0.008 mm, and zero burr formation around connector ports.
ZWH Tooling Solutions & Value: ZWH provides DLC (Diamond-Like Carbon) coated micro end mills and single-crystal diamond (SCD) tools with polished flutes and high rake angles. These tools prevent aluminum adhesion, reduce cutting resistance, and deliver mirror-like chamfer highlights, eliminating post-machining manual polishing and boosting mass-production yields.
