Robotic Polishing Cell System

SAG-Tek Robot Polishing Cells (RPC) automate polishing and surface finishing for complex, high-value components in aerospace, precision optics, medical devices, and mould manufacturing. They replace manual polishing with consistent, operator-independent results, each run.

System Capabilities

Precision Surface Finishing

RPC systems combine 6-axis robotics, CNC motion control, and SAG tools to deliver fully automated polishing workflows. Designed for industrial production environments where surface quality, repeatability, and throughput cannot be compromised.

Robotic polishing automation

FAQ

Common Questions

Can't find what you're looking for? Our engineering team is available to discuss your specific application.

What materials can the RPC system finish?

The RPC is compatible with metals (titanium, aluminium, steel, nickel alloys), ceramics, glass, silicon carbide and many more. Tool selection is matched to the material and target roughness.

What surface roughness can the RPC achieve?

The system regularly achieves Ra < 0.01 μm (10 nm) on metallic and optical surfaces. Target roughness depends on starting surface condition, material, and tool selection.

How long does a typical polishing cycle take?

Cycle time depends on component geometry and starting surface condition. Compared to manual polishing, RPC reduces cycle time by approximately 60% on typical production components.

Can the RPC handle complex 3D geometries?

Yes. The 6-axis robotic integration, combined with SAG's compliant tools, allows the system to access concave, convex, and freeform surfaces that rigid CNC tools cannot reach.

Is the system suitable for low-volume, high-value parts?

The RPC is equally effective for one-off high-value components and batch production. The process parameters are saved per part, so repeat runs require no re-programming.
