The Grade Mark Reader delivers accurate readings for at least 99.7% of all boards, at any line speed. The GMR is currently operating in a mill at 280 lugs per minute and is capable of going much faster. Lucidyne's GMRs have been used with the newest rotary lug loaders to ensure that they can perform in the most demanding applications.
The GMR operating system also supports the capture of rejected symbols for analysis. This helps identify individual Graders and the specific marks with which they might be having trouble. This is especially helpful in high-speed operations when Graders are encouraged to write quickly to keep up with line speeds.
