The Five Pillars of Measurement Accuracy 1. Precision Engineering & Design Accuracy begins at the drawing board. Manufacturers must design instruments that minimize inherent errors—such as parallax, friction, and thermal expansion—through careful selection of mechanisms, materials, and geometries.
Hoshing’s approach: Hoshing’s products are engineered to achieve accuracy up to ±0.001mm for measuring instruments and runout of ≤0.002mm for CNC tool holders. This level of precision is embedded in the design phase, with critical components machined to micron-level tolerances using advanced CNC machining centers.
2. Material Quality & Heat Treatment The raw materials used directly affect dimensional stability, wear resistance, and long-term accuracy. Inferior materials can deform under temperature changes or wear down quickly, leading to drift in measurements.
Hoshing’s approach: All products are manufactured from hardened alloy steel and wear-resistant materials. Critical components undergo a controlled heat treatment and hardening process to enhance hardness, wear resistance, and dimensional stability. Advanced surface treatment technology extends service life by 30% compared to standard products, ensuring that accuracy is maintained over thousands of measurement cycles.
3. Rigorous In-Process & Final Inspection Accuracy is not guaranteed by design alone—it must be verified at every stage of production. Manufacturers should implement inspection checkpoints throughout the manufacturing process, not just at the end. 4. ISO 17025 Calibration Laboratory & Traceability Calibration is the cornerstone of measurement accuracy. Without traceable calibration, a measurement is just a number—it cannot be trusted or verified against international standards.
Hoshing’s approach: Hoshing maintains its own ISO 17025-accredited calibration laboratory–. 5. Environmental Control Temperature and humidity significantly affect measurement accuracy. The international standard reference temperature for dimensional measurement is 20°C–. Even small deviations can cause thermal expansion or contraction in both the workpiece and the measuring instrument. Hoshing Metrology addresses all five pillars—precision engineering, material quality, rigorous inspection, ISO 17025 calibration, and environmental control—to deliver measurement accuracy that is not just claimed, but verified and traceable.
