How to Use Calibration Meter Correctly on Lathe and Horizontal Machining Center

Every time we debug the machine tool, we will use measuring tools, and the common one is meter calibration.

When using the calibration meter on horizontal machining centers and lathes, more attention should be paid to it, because the way in which the calibration meter is placed has changed.

On the vertical machining center, the calibration meter is installed vertically. No matter it is attached to the protective cover of the spindle with a magnetic base or placed in the cutter head, the direction of gravity does not change, so the measurement results will not be affected.

However, on horizontal machining centers and lathes, if the magnetic base is installed on the spindle, when the spindle rotates, the direction of gravity will also change, which will cause slight deformation of the meter clamping bar. The farther the meter is from the magnetic base, the more obvious the deformation.

When the direction of gravity changes, the center of gravity will also change. When the center of gravity is unstable, the measurement results cannot faithfully reflect the current situation.

On the horizontal machining center, the rotation speed of the calibration meter on the spindle will also affect the measurement results, because the centrifugal force will also cause the measurement deviation.

In order to eliminate these adverse effects, it is recommended to use coaxial calibration meter.
