Accurate measurement is essential to ensure the quality of high-precision machined components. To achieve flawless quality, we operate a wide range of optimized inspection and calibration equipment.
3D Coordinate Measuring Machine
To ensure the quality of high-precision molds and automation equipment components, PhyungHwa has implemented 3D coordinate measuring machines (CMMs) for precise measurement and quality verification.
A CMM accurately measures product dimensions, shapes, positions, and tolerances, allowing comparison between design data and the actual product to confirm dimensional accuracy. This minimizes errors in the production process and helps maintain consistent product quality.
Through advanced measurement equipment and a systematic quality management system, PhyungHwa reliably delivers high-quality products that meet customer requirements. We continuously pursue quality improvement to be a trusted manufacturing partner.
Form and Surface Roughness Measurement System
To ensure precise quality control, PhyungHwa has implemented advanced measurement equipment to systematically manage product geometry and surface conditions. By utilizing form measuring instruments and surface roughness testers, we verify both the dimensional accuracy and surface quality of machined components, ensuring consistent and reliable product performance.
