Overview
Manual polishing and grinding are hard, dusty and inconsistent. Robots hold the part against a belt or wheel, or hold the tool against the part, following a programmed path with controlled force.
Force-control or compliant tools keep contact pressure constant, so results are uniform even when the casting varies.
How It Works
- The robot presents the part to abrasive belts or wheels, or moves a spindle over the part
- A force sensor or compliant flange controls contact pressure
- Tool wear is compensated by sensors or timers
- Dust is captured with extraction or water systems
What's Included in the System
- Robot with adequate payload for part or tool
- Force-control sensor or floating tool
- Belt grinders, polishing wheels, deburring spindles
- Dust or slurry collection
- Enclosure with noise reduction
Benefits
- Uniform finish
- Healthier work environment
- Higher throughput
- Lower consumable cost through consistent pressure
Industry Facts & Standards
- Holding contact force constant, instead of tool position, is what keeps surface quality uniform when the part varies
- In one published study, force control cut average roughness from 0.744 µm to 0.335 µm
- Robotic cells remove operators from dust, noise and vibration, which are the main health hazards of manual grinding
- Combustible metal dust (for example aluminium) needs the right collector type; we plan this into the cell
- Standards and safety: ISO 10218 for the robot cell; combustible-dust control (wet or explosion-protected collectors) for metals such as aluminium and titanium.
- Figures are typical ranges from public industry sources, not Zhiyan project results.

Frequently Asked Questions
Can a robot polish complex 3D surfaces?
Yes. Paths are taught or generated from CAD and adjusted with force control.
What parts suit robotic grinding?
Castings, forgings, valves, faucets, wheels, cookware and many metal components.
