The Mitutoyo high accuracy fine graduation micrometer head, with non-rotating spindle, provides highly accurate stage adjustments with a spindle feed of 0.5mm/rev. Its bi-directional graduation allows for easier reading in both directions.
Features & Benefits
The fine-feeding spindle (0.5mm per revolution) on the Mitutoyo high accuracy micrometer head allows for highly precise stage movements and adjustments. The large diameter thimble is easy to turn, and the bi-directional graduation is easy to read in both directions. The non-rotating spindle reduces torsion on the stage or workpiece for added reliability. The spindle’s flat measuring face is constructed of carbide and is lapped for lasting precision.
