Abstract
An automatic grinding machine for end mills for wood, programmable with optical reading of geometric features and for computerized sharpening, has a compact structure, which includes a computerized control panel actuating various assemblies adapted for automated sharpening. A first optical reading assembly has an arm for automatic movement from an inactive position to a position suited for detecting the geometric features of the end mill. A second assembly for holding the end mill is configured to move on command forward and backward and/or simultaneously rotate the mill about its own axis. A third assembly for supporting a cup grinding wheel is mounted on the vertical frame, which rests on a rotatable circular and horizontal base. The grinding wheel can move above and below, longitudinally along the mill and/or in front of it, on the right and left side to sharpen end mills for wood with a left-handed or right-handed helix.
