Outside micrometer FDM-1

precisionhigh-precisionmanual

The FDM-1 is a differential micrometer designed for precision adjustment applications, offering 1.0 inch of travel and 1 micron resolution. FDM differential versions use a combination of precision adjusters to provide 0.030 inch (762 microns) of fine adjustment, with a precision of 20 microns per turn. A large diameter coarse adjustment knob delivers the leverage and resolution necessary to move loads up to 70 pounds. The tip of the adjuster does not rotate, preventing rotational torque on sensitive loads. Laser-marked graduations indicate every micron, enabling true sub-micron motion in a manual actuator. The 1.0 inch coarse travel can be locked and features a scale for rough indication of coarse travel.
