Surface shape measuring instrument performanceThe instrument is improved on the T2450 Roller Convexity Measuring Instrument It is a precision instrument for measuring multi-parameters of surface micro geometry structure and macro geometry profile of various machinery parts.It is widely used in machine-building industry,Website:://.zys-bearing.com,ect,and in laboratories of research institutes and colleges as well as metrological departments of enterprisesFeaturesHigh precision linear base and roundness base e.g.precision air-floated slider or rotating workbenchVarious accessories such as different precision sliders and rotating workbench,adiusted working table, apparatus and sensors etc. available. They can be used in multi-type of combination flexibility and high performanceMany measuring parameters can meet the needs of most geometric profile analysis of surface.the parameters include roughness ,roundness ,concentricity,cylindricity,linearity,parallelism,verticality,angle and profile,ect.
