Autonomous Finishing

Add a finishing shift you don't have to staff.

GrayMatter’s Physical AI sands, grinds, and blasts autonomously — self-programming, adapting to every part in real time. Extend finishing into the hours you can’t fill.

Real intelligence, deployed on real production lines.

Capabilities

One brain. Every finish.

Sanding, grinding, blasting, polishing, buffing — the same Physical AI, deployed across the processes that bottleneck your floor.

Sanding

Delivers defect-free surface finishes across any material, any geometry, without writing a single line of code.

Grinding

Precise material removal across castings, welds, and complex geometries, with AI that adapts to part variation in real time.

Blasting

Automates abrasive blasting with AI that adapts to any surface — rust, scale, and coatings with zero operator exposure to hazardous dust.

Inspection

AI-powered dimensional inspection and defect detection on the production line — real-time quality data on parts of any size or shape.

Polishing

Uses Physical AI to deliver high-gloss, defect-free finishes across metals, composites, and plastics.

Buffing

Consistent, high-shine finishes on metals, plastics, and composites — adapting compound, speed, and pressure to each contour.

Spraying

Applies paints, primers, and protective coatings with uniform thickness and minimal overspray on any geometry, without offline programming.

How a Cell Runs Itself

Three steps.

Then it runs on its own.

Every cell handles the whole loop — perceive, plan, execute — with no programming and no one standing over it. Load the parts, walk away, come back to finished work.

01 / Scan

It sees the part

Physical AI scans each part in the cell and builds a live model of its exact geometry — any material, any shape, straight off the rack. Nothing is pre-taught.

02 / Self-Program

It writes its own paths

The system generates optimized tool paths on the fly — no code, no CAD, no teach pendant. Change to a new part and it re-plans in minutes, not weeks.

04 / Run Unattended

It works the off-shift

Force-controlled robots hold a consistent finish part after part, through the night and the weekend — pushing capacity past the hours you can staff, without adding a crew.

Confidence to Walk Away

Unattended, never unwatched.

Running without an operator only works if something is still watching. Every cell reports to one platform, so a quiet floor never means a blind one.

Operator Stories

The hard part isn't theirs anymore.

Sanding and grinding used to be punishing, repetitive work — shift after shift. Now Physical AI takes it on, and the people who ran those lines are better for it. Hear it from them.
