It achieves unparalleled high precision, high load capacity, and high rigidity.
ISO air spindles and BLOCK-HEAD air bearings, backed by the extensive experience and rich track record of the U.S. Professional Instruments Company (commonly known as PI), achieve unparalleled high precision, high load capacity, and high rigidity through their unique groove compensation bearing structure. In ultra-high precision machining (cutting, grinding) at the nano level, the difference in center rigidity at the air gap (air film) center becomes a significant factor affecting the precision of the machined surface. The air bearings from PI are characterized by their exceptionally high center rigidity, earning them numerous achievements and high acclaim in the fields of ultra-precision machining and measurement, particularly within the optical-related industries both domestically and internationally. *For more details, please contact us or refer to the catalog.
