Cylindrical Setting Masters
Description: Outside diameter setting masters are manufactured in the range of 5 mm to 330 mm as per LS. 4349-1987, to be used for setting the dials of comparators such as comparator stands; dial snaps, air snaps and similar products. Made alloy steel, these masters are sub zero treated at -80°C after hardening to arrest dimensional growth in hardened steels. Form variation of the diameter is controlled within ITO grade of tolerance. Ground and lapped having hardness of 60± 2 HRC, these masters are calibrated under standard room conditions with reference standards traceable to national standards of length through NPL, New Delhi. Each master is supplied with individual calibration certificate with actual size of the master marked on it by electro etching. There are many advantages of using outside diameter solid one piece masters instead of using slip gauge combinations. It does away with the use of costly precision slip gauge box; reduces the incidences of committing errors in building a slip combination leading to heavy losses in the production line; and facilitates the measurement of outside diameters of splined shafts with the help of centre attachment. Cyclo Instruments manufactures these cylindrical setting masters.
