Coaxial Indicators and Tool Alignment

What is the primary purpose of "touching off" a drill chuck on a lathe?

• To clean the chuck and remove debris.

• To ensure the chuck is properly aligned with the spindle's center.

• To lubricate the internal components of the chuck.

• To tighten the chuck securely for drilling operations.

Which specialized tool is used to measure and adjust the alignment of a drill chuck or round bore?

• A micrometer

• A caliper

• A coaxial indicator

• A torque wrench

When using a coaxial indicator, how is the indicator's face kept visible to the operator while the spindle rotates?

• The operator manually holds the indicator steady.

• The indicator's tip rotates around a stationary face.

• The entire indicator rotates, but the operator views it through a mirror.

• The indicator is connected to a digital display that remains stationary.

What is the primary method for adjusting the X-axis (horizontal alignment) of the tool holder during the "touching off" process?

• Manually rotating the spindle by hand.

• Using the jog pendant to move the machine's X-axis.

• Adjusting the height adjustment screw on the tool holder.

• Applying a mallet to gently tap the tool holder.
