    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 working stroke of the movable probe. 

    • Compress the movable probe of the inner diameter gauge with the positioning bridge by hand, and read the data on the indicator gauge.
    • Compress the expansion spring measuring head of the expansion spring inner diameter gauge by hand to measure twice, and read on the indicator gauge.
    • Use a micrometer to measure the steel ball's inner diameter gauge to measure the working stroke of the steel ball.
      When measuring, pay attention to placing the two measuring steel balls between the micrometer anvil and the micrometer screw, and make the axis of the two steel balls coincide with the axis of the micrometer screw.
