Verify system accuracy and calibrate zero-point references on tool presetter machines and machine tool spindles with industrial-grade Calibration Mandrels (test mandrels / master reference arbors). Manufactured with sub-micron precision, these master gauges serve as the physical reference standard for calibrating camera optics, concentricity, and axis zero points on optical and mechanical presetter units. Crafted from ultra-stable, stress-relieved steel and ground to exact length, diameter, and taper tolerances, they ensure consistent, repeatable measurement baseline verification across all tool setting operations.
