Characteristics of cylindrical instrument
The main shaft adopts ultra high precision air floating shaft, so that the instrument has the advantages of high rotation accuracy, good stability, strong bearing capacity, non-contact, non wear, and long life, reaching the national first-class accuracy standard.
Measuring cylindricity of workpiece with multi section method
High precision column guide rail ensures high accuracy and repeatability of workpiece cylindricity measurement.
The worktable and column are made of natural granite to make the mechanical performance of the instrument more stable and reliable, without deformation, drift and beautiful.
The two-stage built-in air filter, a protective pressure relay and an oil-water separator device make the working air pressure of compressed air stable, clean and dry, and ensure good rotation stability and high accuracy of the air floating spindle.
The vertical and horizontal movement of the sensor is driven by a linear motor, which makes the instrument easy to operate and accurate to adjust.
2048 line/cycle high-precision rotary encoder is adopted to ensure the data sampling resolution.
The inductance signal measuring circuit of the instrument is a high-precision LVDT special circuit independently developed by our company. The measuring accuracy and stability are at the leading level in China.
The special measurement analysis management software based on Windows XP operating system has the functions of automatic collection, automatic correction of eccentricity, instrument calibration, digital filtering, measurement parameter evaluation in accordance with the latest ISO standard, measurement result database archiving, printing and output, etc.
