High Accuracy Long Distance Linear Encoder Scale For Large Milling Lathe Boring Machine
Advanced Optical Measuring System
1. Advanced six-spring & push-pull structure to ensure repeatability less than 2 micron；
2. Advanced engineering mechanics analysis and design to ensure that the dynamic speed more than 120 m/min
Aging Test
Easson Optical Linear Scale's reader head need to power on for 72 hours aging test before assemble,the aging test exposes defects in the process, design, materials and other aspects of electronic devices before they leave the factory. Therefore, it is of great significance for companies to modify product designs in time, so that products can be sold after they are aging and stable.
