At REKO, gauge management is more than routine maintenance—it's the foundation of consistent machining quality. Every measuring tool is controlled through strict standards covering daily care, periodic calibration, classification, status identification, and end-of-life retirement.

Why We Implement Gauge Management

In precision machining, gauges are essential tools to ensure dimensional consistency, improve inspection efficiency, and reduce production risks.

A standardized gauge management system helps us:
  • Ensure stable dimensions and functionality, preventing batch defects
  • Improve inspection efficiency and shorten delivery time
  • Reduce rework and customer complaints caused by measurement deviation
  • Enable quality traceability and meet customer/industry standards
  • Extend gauge lifespan and reduce management costs
  • Inspection & Calibration Cycle

    Calibration is performed by certified third-party laboratories or qualified internal personnel.

    To ensure accuracy, all gauges follow a defined calibration cycle:
  • General gauges (calipers, micrometers): every 6 months
  • Special gauges (custom fixtures, dedicated gauges): every 6–12 months
  • High-precision gauges (gauge blocks, ring gauges, plug gauges): every 3–6 months
  • Initial calibration required before first use
  • Early calibration required if deviations are detected

    General Management Requirements

    To ensure standardization and traceability, we follow these requirements:
  • Establish a unified digital register
  • Assign responsible personnel for gauge management
  • Standardized storage (dust-proof, anti-rust, anti-vibration)
  • Strict usage permissions and borrowing records
  • Immediate reporting and handling of abnormal gauges
  • Classification & Numbering Rules

    gauge_management_borrow_record

    1. Quality department unified management.

    2. Production department needs to write an application form to borrow (self-inspection products during production process)

    3. Purchasing department needs to write an application form to borrow (give to oxidation plant for inspection)

    4. 3D and 2.5D are calibrated once a month. (calibrated by internal staff)

    5. Calipers are calibrated once a year (calibrated by third-party inspection company)

    Third-party inspection of measuring tools

    At REKO, all precision measuring tools are sent to certified third-party laboratories for regular calibration to ensure accuracy, reliability, and traceability. Each tool is managed under a strict calibration cycle to prevent measurement deviation and maintain consistent quality standards.
