Robot painting for machine housings and general machinery
General machinery parts with different colours inside and outside are painted from a long seventh-axis floor track, so one robot covers several stations. One engineered layout used five GR6150-2900 robots on a 72 m track with HIWIN guideways, German helical rack and 3 kW explosion-proof motors, with 3-colour plus solvent change and 2K mixing on separate base and topcoat stations.
The numbers behind this configuration
| Track | 72 m seventh axis, HIWIN guideways, module 3/4 helical rack |
|---|---|
| Motors | 3 kW explosion-proof |
| Robots | 5 × CMA GR6150-2900 (8 in the first version) |
| Colour change | 3 colours plus solvent, with 2K mixing |
| Coverage | Bottom, side and top faces, different colours inside and outside |
Figures come from the project records behind the linked projects below, not from a brochure. Your line will differ — these are what we actually built or engineered.
What we supply
- Track length and station positions derived from the part mix and takt
- Colour-change stack and 2K mixing sized to the real change frequency
- Guideway covers and lubrication chosen for a paint environment
- Track quoted per metre — the same unit the buyer will check it in
What this application taught us
No quotation goes out without the three inputs: paint system, cycle time and number of colours. A proposal built without them moved from eight single-gun robots to five with colour change, and the requirement kept moving.
What we need from you
- Part drawings or dimensioned photographs, including the deepest recess to be coated or the full weld list.
- The paint or process specification: 1K or 2K, solvent or waterborne, powder, adhesive or wire, with the required film build or weld size.
- The required output — parts or jobs per hour — and the shift pattern.
- Booth or cell dimensions, the conveyor or hanger arrangement, and the hazardous-area classification your safety engineer has assigned.
