For many jobs that require frequent small distance measurements, ordinary vernier calipers may be difficult to meet the needs. At this time, the micrometer made by the principle of spiral micrometer is particularly important. It not only has a higher resolution (usually up to 0.01mm), but also can easily read the data through the knob, greatly improving work efficiency and accuracy.

An in-depth exploration of this small but powerful measuring instrument reveals that its internal structure is quite sophisticated and complex. It is mainly composed of three parts: fixed anvil, movable rod and rotatable adjusting sleeve. One of the most critical is engraved with uniform pitch line lines of the disc-shaped components-spindle or called "screw", with the above installation of the limit stop and locking device and other accessories under the joint action to complete the whole measurement process.

from aerospace parts assembly inspection to watch parts grinding and verification and other fields can see the active figure of this kind of equipment. For example, the determination of piston ring clearance of automobile engine cylinder block, the calculation of curvature radius of optical lens, etc. all need to rely on such professional-grade measuring instruments to obtain reliable values to support subsequent processes.

Users who are first exposed to this type of product may find it a bit tricky and don't know how to start. Don't worry! In fact, the task can be successfully completed as long as the steps are followed:

-First confirm that the object to be inspected is in a stable state and will not move easily;-Next, push the movable end until it closely fits the target part and record the current display value;-Finally, repeat the above actions for several times to verify consistency to obtain the final average result.

In order to ensure the reliability of long-term use, it is also necessary to pay special attention to some maintenance matters. After each use, the residual substances on the surface should be wiped clean in time to prevent corrosion. Regularly add appropriate amount of lubricating oil to reduce friction loss and prolong service life; The storage environment should also be dry and ventilated away from corrosive gas erosion and other factors.
