Tolerances We Work With at Schilthorn Precision
Every product we deliver at Schilthorn Precision carries the mark of decades-long expertise in manufacturing high-quality, high-performance components. Every project treats precision and accuracy as primary characteristics, making us known for high-precision machining for HVAC, automobile, space and aerospace parts, backed by rigorous process control.
Our capability spans a wide range of materials, manufactured on advanced, rigid CNC machining centres. This rigidity lets us produce precision-engineered components and features to a tolerance band of ±10 microns, verified through our in-house measurement capabilities.
Tolerance Specifications
At Schilthorn Precision, we hold tight tolerances across every geometric characteristic, not just dimensional size. The table below lists our standard tolerance specifications for flatness, circularity, cylindricity, parallelism, perpendicularity and run out, each with its GD&T symbol.
| Title | Value | Symbol |
|---|---|---|
| Flatness | ± 0.01 mm, for the entire surface area of the part. |  |
| Circularity | ± 0.01 mm, for parts as small as 2mm in diameter. |  |
| Cylindricity | ± 0.01 mm, for the entire length of the part. |  |
| Parallelism | ± 0.01 mm, between the Datum & Surface. |  |
| Perpendicularity | 90° ± 0.01, between the Datum & axis. |  |
| Run out | With a variance less than 10 µm |  |
We hold flatness, cylindricity and circularity to ±0.01 mm, including on parts as small as 2 mm in diameter, and we control run out to a variance of less than 10 μm. Parallelism between datum and surface, and perpendicularity between datum and axis, are held to ±0.01 mm and 90° ± 0.01° respectively. These tolerances are measured and verified using the metrology and inspection setup described on our Measurement Capabilities page.
