Measuring bore plug gauge BMD

for external measurements

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,… 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: • Carbide, • Hard chrome, • Ceramic, • Ruby, • Plastic, • Diamond.
