Understanding the Purpose of a Dial Indicator
What is a dial indicator and why is it important?
A dial indicator, also known as a dial gauge or simply a “dial,” is an essential tool used in various industries to measure small linear distances or displacements accurately. These devices play a crucial role in ensuring precision in machining processes by detecting deviations from desired specifications. With their precise measurements, dial indicators help machinists achieve the desired outcomes efficiently.
How does a dial indicator work?
Dial indicators consist of a needle-like pointer attached to a spring-loaded spindle. The spindle moves when pressure is applied against it, causing the pointer to deflect on the calibrated dial face. The deflection indicates the displacement or distance being measured. By reading the position of the pointer on the dial face, operators can determine the magnitude of the displacement with great accuracy.
Applications of dial indicators
Checking runout
One common use for dial indicators is checking runout in rotating components such as shafts or wheels. Runout refers to any deviation from perfect circularity or straightness. By carefully positioning the dial indicator’s contact point against the rotating component, operators can observe any variations as they occur. This information allows them to identify and correct potential issues that may affect performance or cause premature wear.
Aligning components
Dial indicators are invaluable when aligning machine components during assembly or maintenance tasks. Whether it’s aligning gears, pulleys, or other parts that need precise positioning, these tools provide real-time feedback on alignment adjustments made by operators. By monitoring changes in readings as adjustments are made, technicians can ensure optimal alignment for smooth operation and reduced wear.
Measuring deflection under load
In engineering applications where structures bear loads, understanding deflection under load is critical for safety and performance assessment. Dial indicators enable engineers to measure how much an object bends or deforms when subjected to force or weight. This information helps them determine if a structure can withstand the expected loads and identify potential weak points that require reinforcement.
Setting up machinery
When setting up machinery, dial indicators are instrumental in achieving accurate and reliable results. They aid in aligning workpieces, tools, or fixtures precisely, ensuring optimal performance during production processes. By using dial indicators to measure critical dimensions and make necessary adjustments, operators can minimize errors and maximize productivity.
Verifying part dimensions
Dial indicators are widely used for quality control purposes to verify part dimensions during manufacturing processes. By comparing measurements obtained from the dial indicator against specified tolerances, manufacturers can ensure that parts meet required specifications. This helps prevent defective products from reaching customers and maintains consistent quality standards.

Tips and Tricks for Maximizing the Performance of Your Starrett Dial Indicator
Understanding Runout: The Key to Accuracy
Runout is a critical factor that can greatly impact the performance of your Starrett dial indicator. It refers to any deviation from perfect alignment or concentricity, which can result in inaccurate readings. To ensure optimal performance, it is essential to minimize runout as much as possible.
What Causes Runout?
Several factors can contribute to runout in a dial indicator. One common cause is an improperly mounted or misaligned workpiece. When the workpiece is not securely fastened or aligned with the indicator’s measuring axis, it can introduce runout errors. Worn-out contact points or a damaged spindle can also lead to increased runout.
Minimizing Runout
To maximize the accuracy of your Starrett dial indicator, here are some tips for minimizing runout:
- Proper Mounting: Ensure that the workpiece is securely mounted and aligned with the measuring axis of the indicator. Use appropriate fixtures and clamps to hold it firmly in place.
- Check Contact Points: Regularly inspect and replace worn-out contact points on your dial indicator. Damaged or dull contact points can introduce additional runout errors.
- Lubrication: Apply a small amount of lubricant to the spindle and other moving parts of your dial indicator regularly. This helps reduce friction and ensures smooth operation, minimizing potential runout issues.
- Avoid Excessive Force: When taking measurements, apply consistent but gentle pressure on the contact point against the workpiece surface. Excessive force can distort readings and introduce inaccuracies.
By following these steps, you can significantly reduce runout and enhance the precision of your Starrett dial indicator.
Utilizing Back Plunger Attachments for Versatility
One notable feature of many Starrett dial indicators is their compatibility with back plunger attachments. These attachments extend the functionality of the indicator, allowing for more versatile measurement capabilities.
What are Back Plunger Attachments?
Back plunger attachments are accessories that can be attached to the rear of a dial indicator. They consist of a small plunger or probe that extends outward from the backside of the indicator. This design enables measurements in hard-to-reach areas or situations where direct access is limited.
Benefits and Applications
The use of back plunger attachments brings several benefits and expands the range of applications for your Starrett dial indicator:
- Accessibility: With a back plunger attachment, you can measure dimensions in recessed areas, narrow slots, and other confined spaces that would otherwise be challenging to reach with a standard contact point.
- Versatility: The ability to switch between different types of contact points allows for various measurement techniques. You can use flat contacts for measuring flat surfaces or cylindrical contacts for measuring inside diameters.
- Precision Alignment: Back plunger attachments enable precise alignment by providing an alternative reference point on the rear side of the workpiece. This is particularly useful when aligning parts during assembly or ensuring concentricity.
- Depth Measurement: By using a depth rod attachment with your Starrett dial indicator, you can accurately measure depths and step heights without requiring additional tools.
Common Applications of Starrett Dial Indicators
Starrett dial indicators are versatile tools that find applications in various industries and tasks. These precision instruments provide accurate measurements and play a crucial role in ensuring precision and quality in different processes.
