Precise FM-150 125-150 mm Measuring Range Flange or Disc Micrometer

Precise FM-150 125-150 mm Measuring Range Flange or Disc Micrometer is a specialized type of micrometer designed specifically for measuring the thickness of thin materials, such as sheets of paper, plastic, metal, or fabric. It's commonly used in quality control and manufacturing processes where precise thickness measurements are crucial. Here's an explanation of its key features and how it works:

Frame and Anvil: Like a standard micrometer, the flange micrometer consists of a C-shaped frame with a stationary anvil (the fixed reference point) and a movable spindle. These components are designed to accommodate the thin material being measured.

Measuring Faces: The anvil and spindle of a flange micrometer have flat, parallel measuring faces. These faces come into contact with both sides of the material to be measured, ensuring an accurate thickness measurement.

Thimble: The micrometer is equipped with a thimble, similar to standard micrometers, for precise adjustment and measurement. Rotating the thimble moves the spindle to grip the material being measured.

Graduated Scale: The barrel of the flange micrometer features a graduated scale with units of measurement (typically in millimeters or inches). This scale provides a coarse measurement reading.

Disc or Flange: What distinguishes the flange micrometer is the presence of a disc or flange attached to the spindle. This disc ensures that the measuring faces remain parallel and perpendicular to the material being measured, preventing deformation or distortion of the thin material.

Zeroing Function: Like other micrometers, flange micrometers often have a zero-setting function. This allows users to set the instrument to zero at any reference point along the scale, simplifying differential measurements.

How it works:
To measure the thickness of thin material with a flange micrometer, you gently place the material between the anvil and the spindle, ensuring it is flat and evenly aligned. Then, you turn the thimble to close the jaws until the material is securely held between them. The measurement is read directly from the graduated scale, providing an accurate thickness reading.

Flange micrometers are essential tools in industries like paper manufacturing, printing, textile production, and plastic film manufacturing, where precise control over material thickness is critical for quality assurance. Their design ensures that measurements are made accurately without damaging or deforming the thin materials being measured, making them indispensable in these applications.
