Micro Linear Encoder Scale for Micro Milling And Lathe Machine
Linear grating ruler are used in various machines with digital readout System together, which is often used to detect the coordinates of the tool and the workpiece, to observe and track the cutting error, in order to play a role in compensating the movement error.
Advanced Optical Measuring System
The GS series scales of the slide carrier , use a five bearing design for optical grating linear transducer which has been proven as the most reliable system design in today's market.
Sealing Lip
The plastic seals of GS series scales use an innovative material to offer superior oil resistance, high elastic recovery properties and durability, carefully designed lips geometry offer low slide resistance.
