Plek machine

A computer-controlled fret-dressing machine that measures an instrument's neck under simulated string tension and then levels and crowns the frets accordingly.

Its value is measurement: rather than relying on a technician's eye, it maps the actual fret heights along each string path while the neck is loaded, then removes only the minimum metal needed to produce a level plane. Because everything is recorded, the job is repeatable and can be documented. The trade is that a well-trained human doing the same work by hand can reach a result just as good, and hand work is still needed for final polishing and edge dressing.

Example: a guitar with a slight hump at the neck joint can be dressed by the machine to follow the actual curve rather than the intended one.
