摘要： Portable sharpening machine (1) for sharpening wood drill bits (9,9.1,9.2), provided with side handles (2) to facilitate its transport. Said machine (1) is provided with various different apparatuses (5,6,7,8) for aligning the drill bits (9,9.1,9.2), which can be dismounted and remounted and are interchangeable. The drill bits (9,9.1,9.2) are previously fitted into the stem of special drill bit holders (16) which can be reused in various sharpening and alignment stations. The portable sharpening machine (1) has vertically arranged on the side surface an apparatus (5) for preliminary aligning the drill bit (9,9.1,9.2) relative to the drill bit holder (16). The drill bits (9,9.1,9.2) together with the drill bit holders (16) are aligned onto the apparatuses (5,6,7,8) with the aid of reference pins (12) located on the apparatuses (5,6,7,8) and corresponding holes (17) provided on the drill bit holders (16).

摘要： The present invention relates to an automatic grinding machine (1) for end mills for wood (7), programmable with optical reading of the geometric characteristics and computerized sharpening, constituted by a compact structure which can be rested on a fixed bench or on a movable trolley for service on machines for chip-forming machining. The grinding machine (1) has a computerized control panel (2) for CNC management, which actuates in cooperation and coordination various assemblies adapted for automated sharpening. A first optical reading assembly (5) with an arm (4) for automatic movement from an inactive position (3) to a position for detecting the geometric characteristics of the end mill (7). A second assembly (6) for holding the end mill (7), which is horizontal and longitudinal with respect to the machine, capable of moving on command forward and backward and/or simultaneously rotate the mill about its own axis. A third assembly (10) for supporting a cup grinding wheel (11) is mounted on the vertical frame (9), which rests on a circular and horizontal base capable of rotating on said plane. The grinding wheel can arrange itself above and below, longitudinally to the mill and/or in front of it, both on the right side and on the left side, in order to be able to sharpen end mills for wood of the type with left-handed helix and of the type with right-handed helix.
