    Q1: What is a dial bore gauge?
    A1: A dial bore gauge is an instrument that measures the inner diameter of small holes. Bore gages are critical when it comes to measuring parts that have small holes in them. Typically, these versatile instruments are used as part of a quality control process to ensure that bore sizes are standardized.

    Q2: Why is a bore dial gauge used?
    A2: A Bore Gage is used to measure the inside diameter of a hole or cylinder. This explains why it is referred to by so many different names. You are actually measuring the bore size.

    Q3: How does a dial bore gauge work?
    A3: A typical bore gauge is comprised of a shaft with a dial indicator at the top and a measuring sled at the base. The measuring sled consists of three guides and an actuating plunger. Dial bore gauges give you quick and accurate readings on the size, less than perfect roundness, or wear.

    Tips: How to calibrate a dial bore gauge?

    Calibrate the force measurement of the movable probe and the contact pressure of the positioning bridge.

    1. The inner diameter gauge with the positioning bridge is placed in the smooth ring gauge with the inner diameter equal to the measurement upper limit and the lower measurement limit of the inner diameter gauge. When the positioning bridge is in these two positions, mark it respectively. Then the contact surface of the positioning bridge is contacted with the end surface of a cylindrical auxiliary table placed on the force measuring device, and pressurized downward. When the positioning bridge is compressed to the positions of the upper measurement limit and the lower measurement limit, read the readings of the force measuring device as calibration results.
    2. The spring-type probe or the measuring steel ball is placed between the measuring device and the pressure rod, and the pressure rod is lowered to compress the spring-type probe or the measuring steel ball to the starting point of the working stroke, take a reading on the measuring device, and then continue to compress the work The end of the stroke, at the indication of the device, is the result of the calibration.
