Universal Length Measuring Machine

This universal length measuring machine uses the principle of Laser Interferometry. It is used specially by the metro-logical standard bureaus, gauge manufactures, calibration laboratories for calibrating of any length measuring instruments like high-end scales, gauges etc...

The focus point is that, it is used to calibrate in the ultra high precision. This sophisticated system can be used for a wide variety of length measurement applications ranging up to several nanometers.

Basic Hardware of the Machine:

Granite Block is the heavy and single block made from granite which has the advantages of stability against the environmental conditions and vibrational effects. And all the other parts of the machine are mounted over the block and so the block is also known as the base of machine.

Laser Source, as the machine uses the principle of laser interferometry; the laser source is the main unit of the length measuring machine. This machine uses laser of fixed wavelength which is usually in between 600-650 nm.

 

                                    















Measuring Head is the another main part of the system, this unit is also mounted over the granite base which combinely uses pneumatic system with the air bearing for movement of the unit while performing job.

Carriage/Table is another supportive unit which is also mounted over the base. The work pieces are clause over the carriage or table.

Tail Stock is the fixed part of the machine that lies in the one end of the base (granite) which acts as like the fixed anvil.

Pneumatic System: The system as a whole needs compressed air for operation despite of electricity.

Software:

Computer and Software is the basic part of the system for processing and the final output of the whole job. As the machine uses laser interferometry principle, the complicated calculations are performed by its special purpose software.
