Precision for your component
Quality in the characteristics that matter
We agree the required characteristics of your component and inspect them at the relevant manufacturing stages. Manufacturing and quality assurance work together.

Brückner Precision
Achievable precision
Our in-house grinding processes are generally designed for components with a diameter of at least Ø 6 mm and a length of at least 15 mm. For large production runs, we assess smaller diameters with suitable feeding arrangements.
One micrometre (µm) equals 0.001 millimetres (mm). The total diameter tolerance width is the difference between the upper and lower permissible diameters. We agree the specific limit sizes for your component.
| Characteristic | Achievable value | Scope |
|---|---|---|
| Surface roughness | Rz < 0.6 µm | Suitable ground outer surfaces |
| Roundness | < 1 µm | Suitable ground cylindrical components |
| Total outside diameter tolerance width | 3 µm | Up to Ø 20 mm, with a suitable grinding process |
| Total outside diameter tolerance width | 4 µm | Above Ø 20 mm and up to Ø 60 mm, with a suitable grinding process |
| Total diameter tolerance width for hard turning | 10 µm | Suitable components on the NLX 2000 Y |
We agree the values for your component based on dimensions, material and geometry. For suitable ground components up to Ø 20 mm, Rz < 0.6 µm, roundness < 1 µm and a total outside diameter tolerance width of 3 µm are achievable together in series production.
Brückner Precision
100% dimensional inspection after hardening
After hardening, our custom visicontrol system inspects every component for diameter, length and edge rounding. Sampling checks then accompany subsequent machining.
During turning, we inspect the dimensions produced at that stage. During lap grinding, we check series dimensions at especially short intervals.

Measuring equipment from Mahr, Mitutoyo and KEYENCE
We use measuring equipment from Mahr, Mitutoyo and KEYENCE, selected to suit the component characteristics and requirements.
Brückner Precision
Individually inspected. Individually packed.
Every piston pin and every crank pin is individually inspected and individually packed at the end of the process, regardless of diameter.
For cylindrical rollers from Ø 8 mm, manual visual inspection and individual packaging are also part of the process.
Brückner Precision
Documentation for your quality assurance
We offer initial samples and make inspection reports available for review on request. An inspection certificate 3.1 to DIN EN 10204 is standard for the material.
Full traceability and the documented link between manufacturing and the agreed requirements support your quality assurance.
