GUM’S ROCKWELL HARDNESS STANDARD MACHINES after MODERNISATION

Abstract

This article describes two twin deadweight-type Rockwell hardness standard machines (HSMs – HSM-S02 and HSM-NT) of GUM after modernisation. A new control system for the station with database, a hydraulic pump, a displacement measuring system and an application enabling the operator to operate the measuring station are described. The adjustment process of the HSM-S02 with entering automatic compensation (correction) enabling the improvement of the measured result in real time is presented.
