Measurement of special bearing ring with large range and multi-function

DTP-2600 series roundness tester can quickly measure roundness, surface waviness (Wc, Wp, Wv, Wt, Wa, Wq), static (displacement type) waviness, dynamic (speed type, acceleration type) waviness, coaxiality, perpendicularity, parallelism, flatness, spectrum analysis, wave height analysis, runout and other parameters of various annular workpieces (four methods can be used to evaluate roundness error); Spectrum analysis can be conducted on the surface state of parts; The eccentricity and phase of parts can be given. The waviness value of any wave band can also be processed, and the eccentricity and phase of parts can be given.

Measuring principle

According to the radius measurement method. The rotating shaft system adopts high-precision air floating main shaft as the measurement datum; The electrical part is composed of advanced computer, imported precision circular grating and precision piezoelectric ceramic sensor. The precision circular grating and piezoelectric sensor measure the angular and radial displacement to ensure the accuracy of measuring the angular displacement and radial value of the workpiece; The measurement software adopts DTP-2600 system measurement software based on Chinese Windows operating system platform to complete data acquisition, processing and measurement data management.
