Overview

Why automate
polishing?

Manual polishing is tiring, unstable in quality, and exposes operators to dust, noise, and vibration. Traditional CNC alternatives are expensive and inflexible when products change.

DOBOT cobots offer an in-between solution: ±0.02 mm repeatable accuracy, low installation cost, drag-to-teach programming, and safe collaboration alongside your operators.

  • Repeatable path with ±0.02 mm accuracy on every part
  • Compatible with servo spindles, belt grinders, and buffing wheels
  • Drag-to-teach for fast reprogramming of new products
  • Level 5 collision detection — safe collaboration without a cage
  • Covers metal, wood, and composite materials

Key Advantages

Why cobot-based
polishing?

Consistent Quality

The cobot follows the same path with ±0.02 mm repeatability on every part. Consistent finish from the first to the last part of the shift.

Fast Setup

Plug-and-play installation and drag-to-teach programming. From unboxing to first polished part in a few hours.

Flexibility Across Products

Change the program for a new part in minutes via a visual interface — without custom fixtures or retooling cost.

Operator Safety

Move the operator out of the dust, noise, and vibration zone — Level 5 collision detection ensures safe collaboration.

Setup Configurations

Two typical setups
for every application

We choose the layout based on the size, shape, and weight of the part.

Setup 01

Polishing with Servo Wheel

The cobot holds the polishing tool (foam, felt, or scotch-brite) and works on a fixed workpiece. Ideal for metal surfaces, car hoods, spoilers, and mold finishing.

Belt Grinder & Buffing

The cobot holds the workpiece and presents it to a stationary belt grinder or buffing wheel. Uniform finish in repetitive production — ideal for golf clubs, faucet components, and handles.

FAQ

Frequently Asked Questions

How consistent is finishing quality?
The cobot follows the same programmed path on every part with ±0.02 mm repeatability. That means identical finishing from the first to the thousandth part — something impossible in manual production.
Do I need precise part placement in the fixture?
The cobot can locate the surface via touch sensing and adapt the path relative to a reference point. This significantly reduces fixture cost and setup time between batches.
Which polishing tools can it connect to?
Standard servo spindles, pneumatic random orbital sanders, belt grinders, buffing wheels, and custom tools via the ISO flange. We provide plug-and-play kits for the most common tools on the market.
Is it suitable for production with frequent product changes?
Yes. Programming is done with drag-to-teach: guide the cobot by hand along the desired path and it stores it. New product → new program in minutes instead of hours of CAM programming.
Which cobot model fits my application?
For light polishing and buffing we recommend the CR5A. For medium loads (car hoods, mid-sized metal parts) the CR10A. For heavy grinding with longer reach we recommend the CR20A or a specially configured setup.
