Indi-Ron GT 50

Indi-Ron GT System

• Roundness (application based) software operated under Microsoft Windows XP with a high resolution flat panel LCD monitor.
• Gaussian with selectable Undulations per Revolution (UPR) of 1, 1.67, 5, 50, 150, and 1500.
• Dual Trace Capability.

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.

Accuracy

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.

• Minimum Radial Separation (MRS)
• Least Squares Center (LSC)
• Minimum Circumscribed Circle (MCC)
• Maximum Inscribed Circle (MIC)
