As a precision mechanical transmission device, the micrometer head is widely used in the field that requires
high-precision control and adjustment. Choosing the right differential micrometer head is critical to ensuring
the measurement accuracy and meeting specific working needs. In this atrial, we will learn how to choose
a differential head.
When you choose a micrometer head, there should consider the following contents based on
the actual measurement requirement:
1. Figure dimension.
2. Metric or Inch.
3. Electronic or normal.
4. Install dimension.
5. Travel of micrometer head.
6. Resolution and accuracy.
7. With or without spindle lock.
8. With or without clamp nut.
9. Flat or spherical measuring face.
10. Normal or reverse reading.
11. With or without measuring force device.
12. Rotating or non-rotating spindle (The screw of non-rotating spindle does not rotate,
so it will not generate torqueon the surface of the workpiece, thus reducing the wear on the contact
surface of the workpiece)
In addition, the size of the diameter thimble also affects the reading and positioning accuracy, the larger diameter
the higher reading and positioning accuracy and the smaller diameter the faster positioning. This is also one factor
needs to consider when choosing micrometer head.
