| High Light | Six Axis Robot Aluminum Polishing Machine ，Cast Aluminum Robotic Polishing Machine ，Cast Aluminum Product Polishing Machine | ||
The only robotic polishing system engineered from the ground up for the full spectrum of cast aluminum components — from engine housings and pump bodies to structural brackets and enclosures. Achieve Ra ≤0.05 μm mirror finish or functional Ra ≤0.4 μm in a single automated cell.
Cast aluminum presents a unique combination of challenges that defeat generic polishing machines:
| Challenge | Why It's Hard | Our Solution |
|---|---|---|
| Dimensional variation | Die-cast & gravity-cast parts vary ±0.3-0.8 mm batch to batch | Force-controlled end-effector auto-compensates in real time |
| Complex 3D contours | Curved flanges, internal cavities, boss radii, fillets | 6-axis reach + compliant spindle covers any surface angle |
| Soft, gummy material | Aluminum loads abrasives fast, smears under excess pressure | Adaptive pressure control prevents over-polishing and loading |
| Porosity & inclusion | Sub-surface pores revealed by heavy polishing = scrap | Gentle, consistent force reveals fewer pores vs. manual buffing |
| Multi-surface parts | Sealing faces, OD bosses, cosmetic covers all on one casting | Multi-step program polishes all zones in one fixturing |
Built on a heavy-duty industrial robot platform with a purpose-designed compliant polishing spindle, the LR-POLISH CA Series delivers repeatable, process-validated surface finishing across the widest range of cast aluminum geometries in the industry. One cell. One operator. Unlimited part programs.
Full 6-axis articulation allows the polishing tool to approach every surface of a complex casting at the optimal angle — eliminating the "shadow zones" that defeat 3- and 4-axis gantry polishers.
The proprietary compliant spindle unit measures and adjusts contact force 1,000* per second.
Define up to 12 sequential polishing stages within a single part program:
| Stage | Tool | Target |
|---|---|---|
| Flash / parting line removal | Rotary carbide burr | Dimensional |
| Pre-polish | 320-600 grit flap disc | Ra ≤0.8 μm |
| Intermediate polish | Sisal buff + cutting compound | Ra ≤0.2 μm |
| Fine polish | Cotton buff + fine compound | Ra ≤0.1 μm |
| Mirror finish | Flannel buff + mirror compound | Ra ≤0.05 μm |
Import casting CAD (STEP / IGES / STL) → generate polishing paths in simulation → deploy to robot. No teach pendants. No production downtime for new model introduction.
Optional integrated contact profilometer checks Ra on critical surfaces after each cycle. Auto pass/fail with SPC data logging — full traceability per part.
Robot polishes Part A while operator loads/unloads Part B. Effective robot utilization: >92%. No idle time between cycles.

Import casting CAD → Generate OLP path → Simulate & validate → Deploy in < 10 min
Operator places part on dual-station rotary fixture (Station B loads while A polishes)
6-axis robot runs multi-stage program: deburr → pre-polish → fine polish → mirror finish
Inline Ra probe checks critical surfaces auto pass / fail logged
Finished part exits with Ra cert & SPC data stamp
Next part enters Station A; zero robot idle time
Every LR-POLISH CA cell is delivered with full documentation:
