Straight-edge rulers (Made of ceramic)
Ultraportable high-reliability and high-accuracy straight-edge rulers
Features
-
High-accuracy measurement: Straightness of 2 μm or less is achieved with 3-m straight-edge rulers.
The straightness of 3m-long, metal or stone straight-edge rulers is 7 to 14 μm but that of ceramic straight-edge rulers is 2 μm or less, thus enabling high-accuracy measurement. -
Lightweight and easy to measure and carry around
This 3m-long ceramic straight-edge ruler is about half (about 50 kg) the weight of metal straight-edge rulers, thus enabling people to carry it around and achieving easy measurement. -
Little change with time
Ceramic straight-edge rulers provide high hardness and outstanding abrasion resistance. Furthermore, they have a small coefficient of thermal expansion, which results in small deformation caused by temperature changes and makes them less susceptible to environmental influences during measurement.
Application examples:
- Straightness measurement of machine tool table surface
- Parallelism measurement of machine tool clamp surface
- Flatness measurement of table
- Working accuracy measurement on machining centers
- Accuracy inspection of double column type surface grinding machines
- Accuracy measurement of planer machining
- Surface shape measurement, etc. of lapping machines
Accessories
- Inspection report attached
- Decorative wooden boxes
Options
- Issuance of calibration certificate
