The dial bore gauge is a precision measuring instrument, mainly used to measure the size of holes, slots, etc.,
especially suitable for deep hole measurement and occasions where it is inconvenient to use smooth limit gauges.
Its operating principle is based on a lever drive, which pushes the dial gauge pointer to rotate by the movement
of the movable probe and thus reads the measured value.
Q: What should do if the reading of the dial bore gauge is inaccurate?
A: Check whether the probe is worn, whether the workpiece to be measured is clean, and whether the measurement
method is correct. If necessary, the dial gauge can be sent to a professional institute for calibration.
Q: How to choose the right dial bore gauge?
A: Select the appropriate inner diameter dial gauge according to the size range, accuracy requirements
and use environment of the workpiece to be measured. For example, a small diameter dial gauge can be used
for small diameter holes, and a three-point ID dial indicator can be used for large diameter holes.
Q: What parameters can be measured by the dial bore gauge?
A: It is mainly used to measure the diameter, roundness, cylindricity and other parameters of the hole.
