Process of measuring internal diameters is much more complicated than external. Use of reliable and high-quality tool will simplify the task of technical personnel and speed up the production process.
Three-point internal micrometer are used with high accuracy to measure the internal diameters of cylinders, sleeves, through holes and blind holes.
Three-point internal micrometer are used in instrumental and machine-building production, car services, mechanical assembly shops, for example, for measuring engine cylinders.
Operating principle is based on converting the mutual movement of probes , located at angle of 120 º, into the internal diameter.
Modifications of reading devices are nonius (НМТ) and digital (НМТЦ).
Readout of vernier three-point internal micrometer is performed by scales of the sleeve and drum of the micrometer screw, for digital micrometer - digital reading device.
A wide measuring range of three-point internal micrometer allows measuring holes from 2 mm to 1000 mm.
Modern digital three-point internal micrometer with a resolution of 0.0001 mm allow to measure holes in hard-to-reach places at depth up to 3000 mm with high accuracy.
The measurement accuracy with three-point internal micrometer in comparison with two-point type HM, indicator type НИ and НИЦ is achieved due to three-point contact with contour of the measured area.
Advantage of contact in three directions is a self-centering and self-leveling micrometer system, which exclude subjective errors.
Design of three-point internal micrometer provides centering in any hole, cylinder or tube automatically. This excludes the need to center caliper manually.
Micrometer set includes an adjusting ring for initial installation.
Advantage of digital versions is easy to use. You do not need to know a complex system of readings by scale with nonius. Measurement results are displayed directly on the display. Thanks to this, the reading of measurement data and work process is accelerated.
Due to presence of special data exchange interface in modern digital three-point internal micrometer, the measurement results can be transferred to an external device for further processing.
Digital three-point internal micrometer of Ukrainian and foreign production (SYLVAC, DIN) are issued with characteristics that corresponding technical specifications, standards of the manufacturer and other technical standards.
If necessary, digital three-point internal micrometer can be repaired, restored by qualified specialists of enterprises, calibration according to DSTU ISO / IEC 17025 and the issuance of a calibration certificate in an accredited laboratory.
Measuring hole sizes - procedure is more complicated than measuring external dimensions.
Internal micrometer designed to measure the internal diameters of holes, grooves with point-to-point contact.
A wide range of measurements allows to use in various industries for measuring internal dimensions from 50 mm to 8000 mm.
Compared to bore gauge, which works by comparing with gauge block or adjusting rings, Internal micrometer are designed for absolute measurement.
The readout of dimensions is done directly on the scales of the Internal micrometer. This is an advantage of the Internal micrometer.
The micrometer head is set to zero according to adjusting gauge included in the set of Internal micrometer. Then select and screw required number of extension to obtain the desired size.
Convenience of measurements with Internal micrometer is determined by the quick change of extension to obtain the required size.
Internal micrometer have not a device to stabilize the measuring force (ratchet), so the contact force is determined by touch.
For measurements Internal micrometer must be installed perpendicular to the axis of the hole.
Due to the presence of such features, users of Internal micrometer need to get experience.
Internal micrometer is suitable for measuring the size of hard to reach places.
The small size and sectional design make Internal micrometer easy to store and carry.
Internal micrometer refers to mechanical devices and, with careful handling, can last a long time.
Internal micrometer of Ukrainian and foreign production are issued with characteristics that corresponding technical specifications, standards of the manufacturer and other technical standards.
If necessary, Internal micrometer can be repaired, restored by qualified specialists of enterprises, calibration according to DSTU ISO / IEC 17025 and the issuance of a calibration certificate in an accredited laboratory.
