摘要:
A tool for engraving, particularly on glass plates and the like, comprising a shank (2) for insertion in a spindle (12) of a working head (3). The shank is connected to a kinematic chain (20,21,23,24,26,27) for transmitting motion to a grinding wheel (30) whose axis of rotation is substantially perpendicular to the axis of the spindle (12) and whose plane of arrangement comprises the axis of the spindle.
摘要:
A bilateral automatic machine for machining the edges of plates of glass, stone-like and of other plate shaped materials and the like, comprising a supporting frame (1) which has a conveyor (2) for the plates (3) to be machined. There are also provided an abutment shoulder (5) and a movable shoulder (6) for supporting abrasive grinding wheels (10a,10b,10c) which act on the opposite edges of the plates (3). The machine comprises, for each shoulder (5,6), downstream of the last grinding wheel (10a,10b,10c) in the direction of advancement of the plates (3), a sensor (30) for detecting the dimensions of the plates (3) being machined which drives an advancement device (AD.M.) for the advancement of the last grinding wheel. Each grinding wheel (10a,10b,10c) except for the first grinding wheel (10a) along the advancement direction of the plates (3) is provided with a detector (D.M.) for detecting the energy absorbed by the corresponding motor (M) and an actuator (A.M.) for actuating the advancement device (AD.M.) of the grinding wheel that is located immediately upstream as the energy absorbed by the grinding wheel located immediately downstream of it increases.
摘要:
A bilateral edge-type machine for machining the edges of glass, or stone-like plate materials and the like comprising a supporting frame (1) for a plurality of machining heads (2) arranged on both sides of the plate (4) being machined. Each head (2) comprises a structure (10) associated with a supporting body (11) which is connected to the frame (1). The structure (10) has, on one side, a grinding wheel supporting spindle (20) which is directed upward and, on the other side, an actuation motor (30) which is directed upward. The motor (30) is connected to the spindle (20) by way of a belt drive (31).
摘要:
This grinding head particularly for chamfering-profiling machines for glass plate elements comprises a supporting frame (10) which defines a cylindrical body (11) for accommodating and guiding a sleeve (12) which is axially slidable and rotatably supports the actuation shaft (13) of a grinder (14) which is rotated by a motor (19). The sleeve (12) may be moved with respect to the cylindrical body (11) so as to adjust the grinder position by virtue of a kinematic coupling (20, 22) extending between the sleeve and a control shaft (21), which is substantially parallel to the sleeve. The control shaft (21) is fixed in an axial direction and is rotated about its own axis by a positioning motor (30) controlled by a control and adjustment unit (40).
