Easson Axis DRO Digital Readout for Lathe machine 3000mm length
Product Introduction
EA-926 LCD is the latest all in one function digital readout by Easson launch in 2020. It is a practical, multifunctional optical linear scale digital display have been applied to varieties of machine tools like Milling, Lathe, Grinding, Boring machine etc.
By coordinating with linear scales, EA series readouts can accurately display the value of shifting and achieve NC/CNC. You can not afford to miss this if you are looking for a reliable, efficient and cost-effective Digital Readout Device.
Advanced Optical Measuring System
VS Linear scale reader head advantages:
- Advanced six-spring push-pull structure, repeatability less than 1 micron;
- Advanced engineering mechanics analysis and design, dynamic speed is more than 120m/min
- Reader head housing using fully sealed and waterproof design to ensure motherboard circuit for long life service.
