Force-Controlled CNC Polishing Machine For Zinc Alloy Castings

• Force-controlled polishing — protects soft ZAMAK from over-polish & burning
• Plating-ready Ra 0.1 µm — consistent pre-plate surface, fewer rejects
• 10-30 s cycle on small parts (handles, knobs, sliders, housings)
• Auto load/unload — 1 operator runs up to 3 machines

Real-time pressure compensation: ZAMAK castings often exhibit significant dimensional variations; force control adjusts contact pressure every millisecond, preventing over-polishing of localized excess material on the relatively soft alloy.

Controlled temperature: Spindle speed is synchronized with the feed rate, allowing frictional heat to be managed effectively—eliminating surface blackening and blistering.

Programmed consistency: Surface inconsistencies prior to plating are the primary cause of color variation; programmed polishing ensures every workpiece meets the "standard part" specification, significantly boosting the electroplating yield rate.

Automated loading/unloading: Small parts can be fed via vibratory bowls or feed tracks, with automatic unloading and counting; one operator can manage 2-3 machines.

Quick-change fixtures & program library: Supports mixed-line production of dozens of small zinc alloy parts, with changeover times of less than 10 minutes.

Micro-part clamping solutions: Specialized flexible fixtures are available for tiny components like zipper pulls and lock cores, ensuring no damage to the surface finish.
