Understanding the Components of a Dial Bore Indicator

To change anvils on your Alina Compac Geneve Dial Bore Indicator, it’s essential to understand its main components. Here’s a breakdown:

Component	Description
Dial Indicator	Displays the measurement readings on a graduated dial.
Measuring Head	Houses the anvil and other measuring components.
Anvils	Replaceable parts that contact the bore’s surface to determine dimensions.
Locking Nut	Holds the anvil securely in place.
Extension Rod	Used for measuring deeper bores.

By familiarizing yourself with these components, you’ll be better equipped to perform the replacement procedure.

Pre-Replacement Preparations

Before replacing anvils, it’s vital to prepare your workspace and gather the necessary tools:

Tools Required:
- A clean microfiber cloth
- A wrench or spanner (if required for your model)
- Replacement anvils of the correct size
- Calibration rings or a master gauge for post-replacement calibration
Set Up Your Workspace:
- Ensure the area is clean and free of dust or debris.
- Use a soft, non-slip mat to avoid damaging the instrument.
Safety Measures:
- Handle the instrument with care to avoid misalignment.
- Avoid overtightening components to prevent damage.

Step-by-Step Guide: How to Change Anvils

Step 1: Identify the Correct Anvil Size

Before you begin, determine the correct anvil size for your bore measurement. Anvils come in different sizes to accommodate various diameters. Refer to your device’s manual or markings on the anvils for guidance.

Step 2: Loosen the Locking Nut

Locate the locking nut on the measuring head. Using your fingers or a wrench, turn the nut counterclockwise to loosen it. Be gentle to avoid stripping the threads or damaging the device.

Step 3: Remove the Existing Anvil

Once the locking nut is loosened, carefully slide out the current anvil. Inspect the anvil and the measuring head for any signs of wear, debris, or damage. Clean the area with a microfiber cloth if needed.

Step 4: Install the New Anvil

Align the new anvil with the measuring head’s slot. Slide it in gently, ensuring it’s seated properly. Tighten the locking nut by turning it clockwise. Avoid overtightening to prevent restricting the anvil’s movement.

Step 5: Calibrate the Indicator

After installing the new anvil, use a calibration ring or master gauge to verify the accuracy of the instrument. Adjust the dial as necessary to ensure precise measurements.

Step 6: Test the Instrument

Perform a test measurement on a known bore diameter to confirm the instrument’s accuracy. Make adjustments if needed.

Post-Replacement Maintenance Tips

To extend the life of your Alina Compac Geneve Dial Bore Indicator and its anvils:

Clean Regularly: After each use, clean the instrument to remove dust and debris.
Store Properly: Keep the tool in a protective case in a dry, cool environment.
Schedule Calibration: Regularly calibrate the instrument to maintain accuracy.
Inspect for Wear: Periodically check the anvils and other components for signs of wear or damage.

Frequently Asked Questions (FAQs)

What is the proper torque for tightening the locking nut?
Using the correct torque ensures the anvil is secure without damaging the threads. Refer to your tool’s manual for the recommended torque specification.

Can I use the dial bore indicator for materials with irregular surfaces?
The Alina Compac Geneve Dial Bore Indicator can measure irregular surfaces, but specific techniques and anvils may be required for accurate readings.

What should I do if the anvil doesn’t fit properly?
Ensure you are using the correct anvil for your model and that the measuring head is clean and free of debris. If the problem persists, consult the manufacturer.

How do I store spare anvils properly?
Spare anvils should be stored in a dry, dust-free case to prevent rust or damage. Use labeled compartments to organize different sizes.

Can worn anvils be reconditioned or reused?
While it’s possible to recondition anvils in some cases, this requires professional tools and expertise. Replacing them is usually a safer and more cost-effective option.
