dial test indicator Supplier

Finding a reliable dial test indicator supplier can be challenging. This guide explores essential factors to consider when choosing a supplier, different types of indicators, their applications, and maintenance tips, ensuring you select the right partner for your precision measurement needs.

Understanding Dial Test Indicators

A dial test indicator, also known as a lever-type indicator, is a precision measuring instrument used to determine small variations in dimensions or surface irregularities. Unlike a standard dial indicator, which measures displacement along the axis of its spindle, a dial test indicator uses a lever arm to measure displacement perpendicular to the indicator's body. This makes it ideal for tasks like aligning workpieces, checking runout, and measuring surface flatness.

Key Features of Dial Test Indicators

• Measuring Range: The total distance the indicator can measure.
• Resolution: The smallest increment the indicator can display. Higher resolution indicators offer more precise readings.
• Accuracy: How close the indicator's readings are to the true value.
• Repeatability: The indicator's ability to return the same reading under identical conditions.
• Contact Point Material: Typically made of hardened steel, carbide, or ruby, depending on the application.

Factors to Consider When Choosing a Dial Test Indicator Supplier

Selecting the right dial test indicator supplier is crucial for ensuring the accuracy and reliability of your measurements. Here are some key factors to consider:

Product Quality and Range

A reputable supplier should offer a wide range of dial test indicators to suit various applications and budgets. Look for suppliers that carry indicators from well-known brands known for their quality and accuracy. Consider if the supplier provides indicators compliant with industry standards like ASME or ISO.

Technical Expertise and Support

The supplier should have knowledgeable staff who can provide technical assistance and guidance on selecting the right indicator for your specific needs. Do they offer calibration services or repair options?

Pricing and Availability

Compare pricing from different suppliers, but don't compromise on quality. Ensure the supplier has readily available stock to avoid delays in your projects. Consider the supplier's shipping costs and lead times.

Reputation and Reviews

Check online reviews and testimonials to gauge the supplier's reputation and customer satisfaction. Look for suppliers with a proven track record of providing high-quality products and excellent service.

Warranty and Return Policy

A reliable supplier should offer a warranty on their products and a clear return policy in case of defects or dissatisfaction.

Types of Dial Test Indicators Available

Dial test indicators come in various types, each designed for specific applications. Here's an overview:

Standard Dial Test Indicators

These are the most common type of dial test indicators, used for general-purpose measurement tasks.

Miniature Dial Test Indicators

Smaller in size, these indicators are ideal for tight spaces and intricate work.

Long Stroke Dial Test Indicators

Designed for applications requiring a larger measuring range.

Waterproof Dial Test Indicators

Suitable for use in environments with moisture or coolant.

Digital Dial Test Indicators

Offer digital readouts for improved accuracy and ease of use. They often include features like data output for statistical process control (SPC).

Applications of Dial Test Indicators

Dial test indicators are used in a wide range of industries, including:

• Manufacturing: Aligning workpieces on machine tools, checking runout, and measuring surface flatness.
• Automotive: Measuring brake rotor runout, checking crankshaft alignment, and inspecting valve train components.
• Aerospace: Inspecting aircraft components for dimensional accuracy.
• Tool and Die Making: Precisely aligning and inspecting dies and molds.
• Quality Control: Verifying the dimensions of manufactured parts.

Maintenance and Calibration of Dial Test Indicators

To ensure the accuracy and longevity of your dial test indicator, proper maintenance and calibration are essential.

Cleaning

Regularly clean the indicator with a soft, lint-free cloth to remove dirt and debris. Avoid using harsh solvents or abrasive cleaners.

Storage

Store the indicator in a clean, dry place, away from extreme temperatures and humidity. Use the original case or a protective pouch.

Calibration

Calibrate the indicator periodically, typically every 6 to 12 months, depending on usage. A reputable dial test indicator supplier, such as Wayleading Tools, can provide calibration services to ensure accuracy and compliance.

Troubleshooting Common Issues

Sticky Plunger

A sticky plunger can cause inaccurate readings. Try cleaning the plunger and applying a small amount of instrument oil. If the problem persists, it may require professional repair.

Inconsistent Readings

Inconsistent readings can be caused by a loose mounting, worn contact point, or internal damage. Check the mounting and contact point. If the problem persists, the indicator may need to be repaired or replaced.

Bent or Damaged Contact Point

Replace the contact point immediately to avoid inaccurate measurements. Ensure the new contact point is the correct size and material for the application.

Example Scenario: Selecting the Right Dial Test Indicator for Lathe Alignment

Imagine you need to align the tailstock of a lathe. The tailstock is slightly offset, causing inaccuracies in your turned parts. A dial test indicator is the perfect tool for this task.

Here's how you would use it:

1. Mount the dial test indicator on the lathe carriage using a magnetic base or indicator holder.
2. Position the indicator's contact point against the tailstock quill.
3. Move the carriage along the length of the tailstock, observing the indicator's reading.
4. Adjust the tailstock until the indicator reading remains consistent throughout the entire length of the travel.

For this application, a standard dial test indicator with a resolution of 0.001' would be sufficient. The measuring range should be adequate to cover the expected offset in the tailstock alignment.
