Device for measuring roundness, RMI-D420, Metrology

Roundness

• The roundness measuring instrument is comparative to the exact center of rotation, the quantification of cross-sectional roundness is carried out by measuring the change of radius of the actual contour of the workpiece in a position at different angles to the center of rotation with a gauge.
• It is used to measure cross-sectional roundness and the alignment of internal rotation and external rotation and face runout, etc.

Measurement capabilities:

• Parameter: roundness, concentricity, coaxiality, parallelism, perpendicularity, flatness, single radial runout, single axial runout.
• Analytical capability: spectrum analysis, automatic gap/burr removal, waveform analysis.
• Roundness evaluation (4 methods): minimum zone method (MZC), least squares method (LSC), minimum circumscribed circle (MCC) and maximum inscribed circle (MIC).
• Roundness filtering mechanism: 1-15upr,1-50upr,1-150upr,1-250upr,1-500upr,15-100upr,15-500upr,2-15upr
• Gaussian magnification (ISO standard): 1-100000 input range

Technical features:

• The machine worktable and Z-axis column material are made of natural granite, the structure is not deformed, and the performance is more stable and reliable.
• The rotating spindle adopts pneumatic suspension to reduce friction, so the accuracy is maintained longer and the rotation speed is stable.
• The use of high-precision sensors in the X and Z axis direction improves the degree of automation and realizes the function of automatic measurement and data transmission.
• The key components use special alloys and a special treatment process to relieve internal stress, so durability and accuracy are maintained for longer.
