| TOLERANCE |
| Before processing parts can hold very good tolerances |
± 0.025 mm (.001 in.) |
| After processing tolerance depends on feature size |
± 0.5 % |
| Post-processing machining can provide any possible tolerance |
Unlimited |
| Surface finish |
125 micron or better |
| |
| CUTTING SPEED |
| For 1/8" mill, 3-5 mm cut depth, 3-5000 RPM spindle: |
| X-Y | 20 mm/sec typical |
| Z | 15 mm/sec or less |
| Cut speed is relatively independent of the material |
| |
| MATERIAL PROCESSING (for standard materials) |
| Typical processing time | 1-2 days |
| Turnaround time | 2-3 days but depends on processing schedule |
| |
| SAFETY |
| Machining MetaMetal produces uniform small chips
and virtually no respirable dust. The material is not
toxic, but use the same precautions as you would for
machining other plastic and metal materials.
