BMD - Plug gauges for bore measurements
Easy-to-use, self-indicating and self-centering bore gauge for the measurement of inner- and outer diameter, with highest precision and absolute accurate results. Field of application is the production of high-precision bores within a standard range of Ø 2.0 mm (T-BMD) up to 270 mm in serial production.
Plug Gauge BMD allows:
- Static and dynamic measurement
- Detection of dimensional deviations and shape defects
- As a hand tool in bores directly at the machine
- Fitting in measuring fixtures and machines
- A wide selection of basic types in the standard program, supplemented by useful accessories, ensures that nearly all bores encountered in current practice can be measured precisely. Its flexible platform allows a wide area of application:
- Standard- und Through bores: from 2.0 to 270 mm,
- Measurement of Blind Bores(Flat-Bottom): from 2,0 (T-BMD-FB) to 150 mm,
- Measurement of O.D.: from 20 to 100 mm,
- Multiplane plug gauges: from 21 mm,
- Internal gear gauges: from 10 mm cylinder diameter
- 3-Point Measurement: from 8.0 to 100 mm,
- For very small diameters from 2.0 mm to 3.0 mm
- Measurement of parallel distances: from 1.0 (T-BMD-PA) to 30 mm
- Special sizes,shapes and models, e. g. tapered bores
- Extension or limitations of the measuring range, adjustment of the measuring pressure, air supply,…
BMD (standard design) have a hard chrome coating on guiding cylinders, with approx. 1000 HV. Most of them are suitable for rough measurement conditions.
Repeatability:
2-point design =< 1 µm
3-point design =< 2 µm
The selection of gauging contact material depends on composition and design of the work piece:
