    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?

    • Before calibration, the time for the internal diameter gauge and the standard device used to balance the temperature in the calibration room is generally not less than 2 hours.
    • First, check the appearance of the inner diameter gauge to determine whether there are factors that affect the calibration measurement characteristics. For example, the movement of the measuring mechanism of the inner diameter gauge should be smooth, flexible, and free from jamming and blocking. Each measuring head should be easy to replace, and it should be stable and reliable after fastening.
    • Check the surface roughness of the measuring surface of the probe and the spherical radius of the probe. Use surface roughness comparison samples for comparison. It is required that the surface roughness of the inner diameter probe with positioning bridge, the measuring surface of the movable probe and the contact surface of the positioning bridge should not exceed 0.2um.
