Master pin gauges
Master pin gauges have better tolerance, circularity, diameter variation and surface roughness compared to conventional gauges.
| Former standard | Master pingauge | |||
| Tolerance | ±1μm | → | ±0.5μm | |
| Roundness | 0.8μm | → | 0.3μm | |
| Cylindricity | 0.8μm | → | 0.15μm | |
| Roughness | 0.20μmRa | → | 0.05μmRa | |
| *Individual gauges with φ10 smaller diameter can all be used as master pin gauges . | ||||
| Set Range (mm) | Length (mm) | Step | Tolerance | Cylindricity | Roundness | Roughness | HRC Hardness |
|---|---|---|---|---|---|---|---|
| 0.20… 0.99 | 40 | 0.001 | ±0.5 μm | 0.3 μm | 0.15 μm | 0.05 mRa | 58 or more |
| 1.00… 10.00 | 50 |
● Provided with measurement data
In offering our customers safety and trust, measurement data of all master pin gauges are engraved on the case.
● Micron-accurate measurement of inside diameter is possible!
Insert pin gauges sequentially from the smallest diameter and choose the best fit.
● Also, usable as a perfect master gauge for laser scan micrometer.
| Roundness | 0.3μm |
