Disc Type OD Master to Set Beam Gauge/Multigauge
Cyclo Instruments manufactures “DISC TYPE” Outside diameter setting masters in the range of 5 mm to 390 mm; as per our Drg CY-04/ MSD-044; to be used for setting BEAM GAUGE/ MULTIGAUGE & also used on UDOC Apparatus such as SPINN INDIA for Bearing Industry.
Made from alloy steel; these masters are subzero treated @ -80°C after hardening to arrest dimensional growth in hardened steels. Form variation of the diameter is controlled within the IT0 grade of tolerance.
Ground & Lapped having a hardness of 60± 2 HRC; these masters are calibrated under standards room conditions with reference standards traceable to National Standards of Length through NPL New Delhi. Each master is supplied with an individual calibration certificate with the 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.
