Dial Bore Gauge Measurement Techniques

The video tutorial explains how to use a dial bore gauge to measure the diameter of deep holes with high accuracy. It covers the selection of the correct anvil and spacers, setting the gauge using a setting ring, and the procedure for measuring the bore. The tutorial emphasizes the importance of precision and practice for accurate and repeatable measurements.

What is the primary function of a dial bore gauge?

• To measure the length of a rod

• To determine the weight of an object

• To read the diameter of deep holes

• To calculate the volume of a cylinder

Which model of the dial bore gauge is discussed in the tutorial?

• Model 5678 B

• Model 1234 A

• Model 3089 Z 131 715 J

• Model 9876 C

What is the measurement range of the discussed dial bore gauge?

• 0.7 to 1.5 inches

• 0.5 to 1 inch

• 1.5 to 2.5 inches

• 1 to 2 inches

What components are used along with the dial indicator in the gauge?

• Screws and bolts

• Anvils and spacers

• Nuts and washers

• Clamps and clips

How do you determine the correct anvil and spacers for a measurement?

• By guessing based on experience

• By using a digital calculator

• By measuring the hole with a ruler

• By referring to the gauge chart in the user manual

What is the first step in setting the gauge to a standard?

• Adjust the dial to maximum

• Use a setting ring

• Select the largest anvil

• Remove all spacers

How should the gauge be positioned when setting it to a standard?

• Vertically in the air

• Horizontally on a table

• At an angle in the setting ring

• Flat against a wall

What should you do if the dial is not at its minimum position?

• Add more spacers

• Adjust the dial face to zero

• Ignore it and proceed

• Replace the anvil

What indicates that the measurement is within tolerance?

• The dial does not move

• The dial reads plus five thousandth

• The dial reads minus two thousandth

• The dial reads zero

What is the final step after taking a measurement?

• Leave the gauge in the hole

• Disassemble the anvil and spacers

• Record the measurement

• Recalibrate the gauge
