Mitutoyo 215-151-10 Granite Comparator Stand User Manual

Introduction

This manual provides essential information for the proper setup, operation, and maintenance of your Mitutoyo 215-151-10 Granite Comparator Stand. Please read this manual thoroughly before using the product to ensure safe and efficient operation.

The Mitutoyo 215-151-10 is a precision granite comparator stand designed for stable and accurate measurement applications. Its granite base provides excellent stability and resistance to environmental changes, making it ideal for precise comparative measurements.

Safety Information

Always observe the following safety precautions to prevent injury and damage to the instrument:

• Handle the stand with care to avoid dropping or impacting the granite base, which could cause damage.
• Ensure the stand is placed on a stable, level surface before use.
• Do not apply excessive force to the indicator holder or adjustment mechanisms.
• Keep the stand clean and free from dust and debris to maintain measurement accuracy.
• Store the stand in a dry, temperature-controlled environment when not in use.

Components

The Mitutoyo 215-151-10 Granite Comparator Stand consists of the following main components:

• Granite Base: A stable, precision-ground granite block that serves as the foundation.
• Vertical Column: A sturdy metal column mounted vertically on the granite base, providing the main support for the indicator holder.
• Indicator Holder: An adjustable clamp mechanism that slides along the vertical column and secures a dial indicator or probe.
• Fine Adjustment Knob: A mechanism on the indicator holder for precise vertical positioning of the indicator.

Setup

1. Unpacking: Carefully remove the comparator stand from its packaging. Inspect all components for any signs of damage during transit.
2. Placement: Place the granite base on a clean, stable, and level workbench or surface. Ensure there is no wobble.
3. Indicator Mounting: Loosen the clamping screw on the indicator holder. Insert the stem of your dial indicator or test indicator into the holder. Tighten the clamping screw securely, ensuring the indicator is held firmly without excessive force.
4. Initial Positioning: Loosen the main clamping knob on the indicator holder to allow it to slide freely along the vertical column. Position the indicator approximately at the desired height for your measurement. Tighten the main clamping knob.

Operating Instructions

The Mitutoyo 215-151-10 Granite Comparator Stand is designed for precise comparative measurements when used with a suitable dial indicator or test indicator.

1. Zero Setting: Place the master part or gauge block on the granite base directly beneath the indicator's contact point. Lower the indicator until its contact point touches the master part.
2. Fine Adjustment: Use the fine adjustment knob on the indicator holder to precisely set the indicator to zero (or a reference value) while it is in contact with the master part. The fine adjustment provides a 1 mm range for precise positioning.
3. Measurement: Carefully remove the master part and place the workpiece to be measured on the granite base, ensuring it is positioned directly under the indicator's contact point.
4. Reading: Read the deviation from zero on the dial indicator. This deviation represents the difference in height between the workpiece and the master part.
5. Stability: The black granite base ensures high stability and resistance to burrs and pileups, contributing to consistent and accurate readings.

Maintenance

Proper maintenance will extend the life and accuracy of your comparator stand:

• Cleaning: After each use, wipe down the granite base and metal components with a clean, lint-free cloth. For the granite base, a mild, non-abrasive cleaner specifically designed for granite can be used if necessary, followed by thorough drying.
• Storage: Store the stand in its original packaging or a protective cover when not in use to prevent dust accumulation and accidental damage. Keep it in a stable environment, away from extreme temperatures or humidity.
• Inspection: Periodically inspect all clamping mechanisms and the vertical column for any signs of wear or looseness. Ensure all screws are snug.
• Avoid Impact: Never drop or subject the stand to sudden impacts, as this can damage the precision-ground granite surface and affect accuracy.

Troubleshooting

If you encounter issues with your comparator stand, consider the following common problems and solutions:

• Issue: Indicator readings are inconsistent or inaccurate.
  Solution:
  • Ensure the granite base is clean and free of debris.
  • Verify the stand is on a stable, level surface.
  • Check that the indicator is securely clamped in the holder.
  • Inspect the indicator itself for proper function and calibration.
• Issue: Indicator holder slides down the column after clamping.
  Solution:
  • Ensure the main clamping knob is tightened sufficiently.
  • Clean the vertical column and the inside of the indicator holder clamp to remove any oil or dust that might reduce friction.
• Issue: Fine adjustment knob is stiff or not working smoothly.
  Solution:
  • Inspect for any debris obstructing the mechanism.
  • Apply a very small amount of light machine oil to the moving parts if necessary, but avoid over-lubrication.
