When your gasket tolerances demand perfection—especially on intricate bolt patterns, tight internal diameters, or multi-layer PSA stacks—±0.1 mm isn’t just a spec. It’s the difference between a flawless seal and costly field failures.
But how do modern CNC digital knife cutters consistently hit this benchmark on materials like graphite foil, filled PTFE, or firm elastomers? It’s not magic. It’s a tightly integrated system of mechanics, tooling, vacuum control, software intelligence, and disciplined process validation.
This guide breaks down exactly what makes sub-0.1 mm accuracy possible—and who needs to understand it.
