Precision Measuring Tools for Quality Control
Quality control depends on precise, calibrated measuring instruments. Hooguu stocks measuring tools for manual inspection, on-machine probing, and shop-floor metrology. Brands include Mitutoyo, Mahr, Tesa, INSIZE, and OEM tool presetter probes.
Categories of Measuring Tools
Linear Measurement
- Calipers — Digital, dial, vernier; 6", 8", 12" most common. ±0.01mm accuracy typical.
- Micrometers — Outside, inside, depth; 0-25mm to 100-125mm ranges. ±0.001mm accuracy.
- Height gauges — Granite-base height masters, digital readout, 300mm or 600mm reach.
- Bore gauges — Two-point and three-point for hole diameter measurement.
Surface and Form
- Surface roughness testers — Portable Ra/Rz measurement, Mitutoyo SJ-210 typical
- Dial indicators — Mechanical and digital, various stem and back-plunger styles
- Test indicators — Lever-type for tight-access measurements
- Magnetic stands — On/off magnetic bases for indicator mounting
Threading and Special Gauges
- Thread plug gauges — Go/No-go for inspecting tapped holes
- Thread ring gauges — For external thread inspection
- Plug and pin gauges — Class X precision for hole tolerance verification
- Radius gauges — Standard sets for fillet/round measurement
Tool Presetting
- Probe systems — Renishaw OMP/RMP compatible touch probes for spindle
- Tool length sensors — Z-axis tool setters for automatic tool length compensation
- Presetter accessories — Reference standards, calibration masters
Choosing the Right Accuracy Class
Match measuring tool accuracy to part tolerance using the 10-to-1 rule: instrument accuracy should be 1/10th of the tolerance band. For ±0.01mm tolerance use ±0.001mm micrometer; for ±0.001mm tolerance use a CMM.
Calibration and Traceability
All precision measuring tools require periodic calibration to NIST/ISO traceable standards. Mitutoyo and Mahr instruments ship with factory calibration certificates; recalibration is recommended every 12 months for production use, every 24 months for occasional use.
