2. 제품 특징
The Mahr Snap Gauge 840FS 100-150mm incorporates several design elements to ensure high precision and user comfort:
- 다용도 측정: Capable of measuring all cylindrical workpieces, suitable for direct use on machine tools or within a dedicated measuring room.
- Heat Insulation: Features a heat-insulated handle to prevent heat transfer from the operator's hand, minimizing thermal expansion errors during measurement.
- 견고한 구조: The hardened frame is designed for durability and stability.
- Precision Spindles: Both measuring spindles are crafted from hardened stainless steel and are mounted on long guide ways, ensuring smooth and accurate movement.
- Carbide-Tipped Measuring Faces: The measuring faces are carbide-tipped for wear resistance and are slightly chamfered to facilitate easy positioning on the workpiece.
- Direct Indicator Transfer: The design ensures maximum precision spindle movement is transferred directly to the attached indicator.
- Stable Measuring Force: An internal spring mechanism eliminates user influence on the measuring force, providing consistent and stable readings.
3. 설정
Before using the Mahr Snap Gauge, ensure it is properly set up:
- 짐 풀기: Carefully remove the snap gauge from its packaging. Inspect for any signs of damage during transit.
- Indicator Attachment: The snap gauge requires a separate indicator (not included) for measurement readings. Mount a suitable precision indicator securely into the designated slot on the gauge frame. Ensure the indicator is firmly seated and aligned.
- 구경 측정: Before initial use and periodically thereafter, calibrate the snap gauge with a known standard (e.g., a master ring gauge) within its measuring range (100-150mm). Follow the calibration procedure specific to your chosen indicator.
- 환경 조건: Operate the gauge in a stable environment, free from excessive vibrations, dust, and significant temperature fluctuations, to maintain measurement accuracy.
4. 사용 설명서
Follow these steps for accurate measurement using the Mahr Snap Gauge:
- 작업물 준비: Ensure the cylindrical workpiece to be measured is clean and free from burrs or contaminants.
- Hold Gauge Correctly: Grasp the snap gauge by its heat-insulated handle. Avoid touching the metal frame directly with bare hands for extended periods to prevent thermal expansion.
- 위치 게이지: Gently open the measuring faces by pressing the movable spindle. Position the gauge over the workpiece, ensuring the workpiece is centered between the carbide-tipped measuring faces. The chamfered edges of the measuring faces aid in proper positioning.
- 측정: Release the movable spindle slowly, allowing the internal spring to apply a consistent measuring force. Observe the reading on the attached indicator.
- 반복 측정: For critical dimensions, take multiple measurements at different points along the workpiece to account for any variations.
- 기록된 측정값: Document all measurement readings accurately.
5. 유지관리
Regular maintenance ensures the longevity and accuracy of your snap gauge:
- 청소: After each use, wipe down the gauge, especially the measuring faces, with a clean, lint-free cloth. If necessary, use a mild cleaning solution or isopropyl alcohol, then dry thoroughly.
- 매끄럽게 하기: Periodically apply a thin film of light machine oil to the guide ways of the spindles to ensure smooth operation. Avoid over-lubrication.
- 저장: Store the snap gauge in its protective case in a dry, temperature-stable environment when not in use. Avoid storing it in direct sunlight or areas with high humidity.
- 점검: Regularly inspect the measuring faces for wear or damage. If significant wear is observed, contact Mahr service for potential reconditioning or replacement.
6. 문제 해결
If you encounter issues with your Mahr Snap Gauge, consider the following:
- 부정확한 판독:
- Ensure the indicator is properly mounted and calibrated.
- Check for debris on the measuring faces or workpiece.
- Verify that the workpiece is correctly positioned and the measuring force is stable.
- Consider environmental factors like temperature fluctuations.
- Sticking Spindles:
- Clean the guide ways and apply a small amount of lubricant.
- Check for any physical obstructions or damage to the spindle mechanism.
- Gauge Damage: If the gauge frame or measuring faces are visibly damaged, do not attempt to repair it yourself. Contact Mahr customer support for assistance.
