Marposs - M1 Star MBG - Mechanical Bore Gages

The M1 Star™ MBG (Mechanical Bore Gauge) is the ideal manual
instrument for precision measuring of inside diameter, ovality and
cylindricity.
Measurable diameters: 3 to 300mm (0.12”-11.81”).
Special versions available for bigger diameters.
It can be totally retooled or repaired by simply replacing the nosepiece
and contacts.
A mechanical positioning system automatically ensures alignment
between the nosepiece and the contacts.
The Mechanical Bore Gauge is accurate, robust, reliable and easy to use.
Maintenance free construction requires only periodic cleaning of the
precision mechanism.
A wide range of modular components makes it possible to configure
the bore gauge to meet all your measuring needs.

Measurable diameters: 3 to 300 mm (0.12”-11.81”). Special versions available for bigger diameters.
With an extensive range of accessories, it is possible to measure at depths of more than 500
mm and measure bores that are perpendicular to the axis of insertion.
The durable measuring transmission system is capable of more
than 10.000.000 measuring cycles.
Metrological performances guaranteed for all measurable diameters.
The mechanical transmission measuring system can be interfaced with any pencil probe, dial
or digital indicator.
The linear designed mechanical transmission system has an extensive range of accuracy and
only one master is needed for zero setting.
Compatible with the bore gauge accessories of the main competitors.
Fast delivery times

repeatability <1 micron for the mechanical gauge head and <0.5 microns for the electronic gauge head
range from 3 to 375 mm (0,12- 14,76 ") and measuring depths up to 500 mm
dedicated solution for the measurement of conical bores, ovals, gears, width, distances and bores with axis perpendicular to the direction of introduction of the gauge
the measuring cells contacts can be provided in different materials and radii depending on the material and the roughness of the bore
