Design and Build Quality of the 511713 Dial Bore Gauge
The construction of the Mitutoyo 511713 emphasizes rugged shop floor use while maintaining precise bore measurement performance. A hardened steel spindle with a center groove supports stable alignment inside bores, reducing tilt and improving reading consistency. The 50 to 150 mm measuring arrangement delivers repeatable positioning, and the shockproof CG dial minimizes parallax errors in challenging lighting conditions.
The frame and anvils are built from hardened steel to resist wear from frequent bore inspections and repeated contact with rough surfaces. Protective finishes and carefully ground measuring faces help maintain smooth travel and reduce binding during setup. The overall balance of the tool makes it easy to handle during extended inspection routines, supporting ergonomic operation without sacrificing accuracy.
How to Calibrate and Verify Accuracy
Regular calibration of the Mitutoyo 511713 ensures continued bore measurement reliability and traceability to national standards. Verification with master rings or gauge blocks within the 50 to 150 mm range helps detect wear or damage early, preserving measurement integrity over time. Following the manufacturer recommended adjustment and maintenance procedures further safeguards long term performance and measurement confidence.
Operators should inspect the spindle, anvils, and dial face for damage before each use, confirming that no burrs or chips interfere with smooth travel. Clean measuring surfaces and consistent test conditions reduce setup variability, so recorded bore values remain reliable across shifts and inspection teams.
Setting Up for Repeatable Bore Measurements
Proper setup of the genuine Mitutoyo 511713 dial bore gauge enhances accuracy, reduces positioning errors, and supports efficient inspection routines. A stable mounting fixture or height gauge table provides a consistent reference plane when measuring bore diameters and verifying clearances.
- Securely clamp the gauge on a level surface or mounting block to prevent movement during measurement.
- Select standard anvils that match the bore range and clean any chips or debris from contact surfaces.
- Zero the dial indicator using a master ring or calibrated bore gauge setter at the target measuring size.
- Rotate the spindle slowly through the bore to check for out of round conditions and capture minimum and maximum readings.
Key Takeaways and Best Practices
- Use only genuine Mitutoyo accessories and calibration standards to preserve measurement traceability and tool accuracy.
- Maintain clean, undamaged anvils and spindle faces for consistent contact and reliable bore readings.
- Verify the gauge on a master ring or standard at the beginning and end of each inspection shift.
- Record environmental conditions, as temperature variations can affect steel dimensions and measured bore values.
- Follow a scheduled calibration plan aligned with your quality management system requirements.
FAQ
Reader questions
Can this gauge measure tapered bores accurately?
Yes, by manually rocking the spindle and recording the maximum and minimum readings, you can estimate taper within the 50 to 150 mm measuring range.
Which industries commonly use the Mitutoyo 511713 dial bore gauge?
Automotive, general machinery, and precision manufacturing sectors rely on this gauge for bore size verification, clearance checks, and quality control.
What maintenance schedule is recommended for the 511713?
Inspect and clean after each use, check for spindle and anvil wear monthly, and perform formal calibration at least annually or sooner if handling is rough or measuring performance drifts.
Is the 001mm dial resolution sufficient for tight tolerance bores?
For most bore inspection tasks up to 150 mm, the 0.01 mm dial resolution provides adequate sensitivity, but applications below 0.01 mm may require a digital or comparative device.
