Factors affecting the coaxiality of Coordinate Measuring Machines (CMMs) essentially boil down to: inaccurate axint, unstable workpieces, machine inaccuracy, unstable environment, and improper methods. I have compiled this into the most practical, ready-to-use version for the shop floor, without unnecessary erbosity. I. Machine Inherent Accuracy (Root Cause)Geometric AccuracyPerpendicularity, straightness, pitch, and yaw of the three…

Precision granite platforms and components are upgrading in five major directions: high precision, integration, intelligence, greenness, and servitization. The core driving force is the rigid demand of high-end manufacturing sectors such as semiconductors, new energy, and aerospace for “extremeility data perception green compliance.” I. Materials and Performance: Extreme Stability and Composite InnovationBreakthroughs in precision limits:…
