Description:
This micrometer head with measurement up to 13mm, total length is 61mm. Its carbide-tipped spindle is exceptionally flat,
accurate, and durable. The ratchet thimble mechanism provides an even, constant force.

As one adjustable positioning device, micrometer head can be adjusted down to the micrometer. The essence of the differential
head is to use the principle of gears to convert the rotation of rotational motion into linear insertion and exit movements.
It uses two gears of different diameters for a third moment differential action that converts subtle changes in rotation into linear
insertion and exit movements, enabling precise control of small distances.

Precautions:
1. Precise calibration of the differential head: The calibration of the differential head should be performed prior to use.
Using about 1/10 of the range of an ordinary dial gauge, turn the differential head during the reading process to see
if the reading can be repeated. If so, the micrometer head is working properly; If not, precise calibration is required.
2. Set the appropriate measurement range: Before measuring, you should choose the appropriate measurement range,
usually 0-5mm,0-6.5mm, 0-13mm, 0-15mm, 0-25mm or 0-50mm, etc. Choosing the right range can help improve the precision
and accuracy of your measurements.
3.Correct Measurement Process :
Try to keep the micromotion head perpendicular to the measuring object.
After touching the object, carefully feel the contact between the micro-moving head and the measured object to avoid uneven force.
Once it is confirmed that the contact with the object to be measured is truly stable, the reader should read in a vertical direction
to avoid deviations due to incorrect angles of the reader.

Applications:
1. Optics: micrometer heads are used in the production and inspection equipment of disc reading lenses such as DVDs, MDs,
and CDs, as well as writable optical heads, to provide the critical precision control especially on curved positioning platforms.
2. Liquid crystal projection technology: micrometer head plays an important role in the prismatic positioning and film loading process,
ensuring the clarity and accurate focus of the image.
3.Fiber Optic Technology & Optical Communications: micrometer head ensures the accuracy of signal transmission in the manufacturing
and testing equipment of fiber optic positioning and optical communication system products.
4.Liquid crystal production and inspection: In the liquid crystal display manufacturing process, micrometer head is used to adjust
and test the equipment with high precision.
5. Semiconductor industry: micrometer heads are widely used in semiconductor production equipment and inspection
and evaluation equipment to ensure the accuracy of the process.
6.Mechanical engineering and industrial applications: micrometer heads are often used for the adjustment of machine tools,
precision tools and special gages, especially where an accuracy of thousandths of a millimeter is required, e.g. with carbide probes,
which can be straight or rotary, with options flat or spherical, with or without locking function to maintain a constant measuring force.
