CNC Machine Tool Encoders Optical Spindle Encoder grating components connect directly with the lathe spindle can replace the synchronous pulley or bearing spacer, eliminating the synchronous pulley and coupling of the traditional lathe spindle mounted encoder. All components, such as mounting flanges, reduce production costs. The sensor widely used in CNC industry.

Linear scale displacement position sensor is often used in machine tools, machining centers and measuring instruments. It can be used as an optical linear scale encoder displacement or angular displacement detection. CNC machine tools are often used to detect the coordinates of cutting tool and workpiece to observe and track the feed error of the tool to play the role of a motion error compensation of cutting tool.
