Components of the system are a portable bench top unit, including precision spindle, mounted on a 16” x 20” granite surface plate, variable speed motor drive, Type CT 8 Centering Table (2-axis non-tilt).
The system’s versatile 18” height stand permits easy measurement of part features, and a high quality granite surface plate provides an accurate datum around an 8” centering table.
Air spindle accuracy of ±3 microinches (±0.0762 micrometer) at worktable level, radially and axially, positive coning error not exceeding 2 microinch/inch (.051 micrometer/cm) above the table.
Powered by PDI's Roundness software the instrument will measure out-of-roundness by four different methods as described by ASME B89 National Standard.
