The Rotary Indexing Table Polishing Machine for Door Hinges is a specialized automatic polishing solution designed for hinge plates, hinge pins, and other hardware components. It uses a rotary indexing table with multiple workstations, allowing continuous loading and unloading while polishing is carried out at different stations. This design ensures high productivity, consistent surface finishing, and reduced manual labor.
Rotary Indexing Table: Automatically transfers door hinges between polishing stations with high positioning accuracy.
Multi-Station Polishing: Several polishing units work simultaneously, enabling multiple hinges to be polished at once.
Automatic Clamping System: Custom fixtures securely hold hinge parts in place during processing.
Surface Finishing Options: Mirror polishing, satin finish, deburring, and edge rounding.
Flexible Setup: Adjustable for different hinge sizes, shapes, and materials (stainless steel, brass, iron, zinc alloy).
Indexing Rotary Table – Ensures stable and precise workpiece positioning.
Polishing Stations – Equipped with buffing wheels, flap wheels, or abrasive belts for different surface requirements.
Custom Fixtures – Designed to hold door hinge plates and pins securely.
Drive & Control System – PLC/CNC automation with adjustable speed, pressure, and cycle time.
Dust Collection & Safety Guards – Maintain a clean, safe working environment.
Door Hinges – Polishing hinge plates, arms, and pins.
Cabinet Hinges – Suitable for small-size decorative hinges.
Furniture & Hardware Fittings – Handles, brackets, and similar components.
High Efficiency: Multi-station design increases polishing capacity.
Consistent Quality: Ensures uniform finishing on all hinge parts.
Labor Saving: Fully automatic operation reduces dependence on manual polishing.
Versatile: Handles various hinge types and materials.
Safe & Clean: Integrated dust extraction and protective covers.
