Robotic Polishing Cell System

SAG-Tek Robot Polishing Cells (RPC) automate grinding, polishing, and surface finishing for complex, high-value components in aerospace, precision optics, medical devices, and mould & die manufacturing. Replacing manual polishing with consistent, operator-independent results — every run, every time.

System Capabilities

Precision Surface Finishing

RPC systems combine 8-axis robotics, CNC motion control, and SAG tooling to deliver fully automated polishing workflows. Designed for industrial production environments where surface quality, repeatability, and throughput cannot be compromised.

Robotic polishing automation

Fully automated cell — no operator involvement during the polishing cycle.

8-axis robotic integration

8-axis robot arm with constant force tool for complex geometry access.

Consistent, repeatable surface finish

Achieve Ra < 0.01μm across every component in the batch, not just the first.

Reduced manual finishing time

Cut polishing cycle times by up to 60% compared to manual hand-finishing.

Production-ready process control

Closed-loop process monitoring with One-page.

Flexible part handling

Configurable fixture for components from 50mm to 1000mm+ across.

Applications

Typical Applications

RPC systems are deployed across advanced manufacturing sectors where surface finish directly affects component performance — from optical clarity and biocompatibility to aerodynamic efficiency and dimensional tolerance.

Aerospace componentsTurbine blades, structural brackets, and optical sensor housings requiring tight surface tolerance and zero rework.

Medical implantsOrthopaedic implants, surgical instruments, and device housings where biocompatibility and surface cleanliness are critical.

Additive manufactured partsPost-process finishing for metal AM components — removing layer artefacts and achieving functional surface quality.

Mould & die finishingInjection mould tools, forging dies, and press tools where polished cavity surfaces directly determine part quality.

Precision engineering surfacesHigh-tolerance components for defence, semiconductor, and instrumentation applications.

Optical and Freeform geometriesAspheric lenses, mirror substrates, and complex optical surfaces requiring sub-nanometre roughness.

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, and silicon carbide. 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 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 tooling, 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.
