Easson Linear Glass Scale Cable For Lathe Milling Machine




Advanced Optical Measuring System
as the most reliable system design in today's market.
The glass grating slideways are lapped, and JIS standard P5 grade bearings are used to achieve smooth and accurate movement and
long working life.

Doubel Seals Design

100% Laser calibration
accuracy comply 100% with the specifications.

ASIC for signal interpolation
of the grating. All frequency multiplication is implemented 100% by hardware phase shifting inside the ASIC to minimize the real time measurement error. Because all resistor ladders for phase shifting are constructed with the same piece of semiconductor inside the ASIC, which have same temperature coefficient, therefore. error drift caused by environmental temperature change is minimized.
