Gantry machines used in the aerospace and die/mold industries process large components that need to be machined accurately. But it is difficult to mount an accurate scale on a gantry machine’s large work envelope. To solve this problem, engineers at Heidenhain Corp., Schaumburg, Ill. (www.heidenhain.us), developed the LC 200, a multisection absolute scale that assembles and mounts on a gantry or other large-scale machine tools. Its tongue-and-groove design lets the extrusions of the scale easily slide together.
The LC200’s optoASIC ensures high output signal quality. The device can be powered by 3.6 to 14-Vdc power supplies.
