Thorough Inspections With ABTech Microform

The foundation of our MicroForm roundness gages is an ABTech that is designed and built with precision air-bearing rotary table, providing stability and robustness. This certified system has an accuracy better than five millionths of an inch. Microform Gage can measure the roundness, flatness, ID to OD concentricity, parallelism, and perpendicularity over a spindle. With the types of spindles we rebuild and the tolerances we must hold, this has become an essential part of our inspection process.
