Workshop Precision: Dial Indicator - Series 2 Guide

Detecting subtle dimensional variations on machined parts presents daily challenges in modern manufacturing facilities. Unreliable measuring gauges cause costly quality control errors and slow down production line checks. The Dial Indicator - series 2 resolves this metrology bottleneck by delivering highly accurate, repeatable comparative measurements in a standard frame size.

This guide explores how integrating a Series 2 dial indicator elevates shop floor accuracy.

What Is the Dial Indicator - Series 2?

The Series 2 is a standard-size mechanical dial indicator manufactured by Mitutoyo for general metrology applications.

Featuring an industry-standard 57 mm (2.24 in) outer bezel diameter, this gauge balances optimal display readability with compact mounting geometry. Quality inspectors mount this tool on magnetic stands, height gauges, and comparative inspection fixtures to measure component runout effortlessly.

Key Operational Advantages

Upgrading to a Series 2 indicator offers clear technical benefits for quality assurance labs:

• Standard Bezel Size: Outer bezel diameter of 57 mm fits standard inspection setups without obstructing workpiece view.

• Fine Graduation Options: Offers precise measurement resolutions down to 0.01 mm, 0.001 mm, or 0.0005 inches.

• Shockproof Design: Specialized internal gearing protects delicate rack mechanisms against sudden spindle retraction impacts.

• Scratch-Resistant Crystal: Coated glass lens prevents oil glare and protects display surfaces from shop scratches.

Common Workshop Applications

Machinists and quality control inspectors rely on Series 2 indicators for vital daily tasks:

1. Shaft Runout Checks: Measure radial and axial runout on turned shafts using magnetic base stands.

2. Surface Parallelism Verification: Traverse components across surface plates to verify top surface flatness accurately.

3. Machine Tool Alignment: Align vise jaws and workpiece reference surfaces on milling machine tables.

4. Comparative Inspection: Check production parts against master gauge blocks during high-volume production runs.

How to Measure Parts in 4 Easy Steps

Follow these simple steps to perform accurate comparative checks:

1. Clean Workpiece Surfaces: Wipe target components and indicator contact points using clean alcohol wipes.

2. Mount Securely: Clamp the gauge stem firmly into a rigid magnetic base or fixture.

3. Set Zero Position: Lower contact point onto your master setting gauge and rotate bezel to zero.

4. Record Readings: Pass target parts under probe and note maximum pointer deflections.

Final Thoughts

The Dial Indicator - series 2 converts complex comparative checks into fast, repeatable routines. By eliminating measurement guesswork, this dependable instrument protects product quality and maintains strict shop standards.Graduation available 0.001mm / 0.005mm Diameter 57mm The spindle is made of high strength quench hardened stainless steel.
