FIELD: methods and apparatuses for working of fragile plates, for example, made of glass and with straight and curvilinear sides. SUBSTANCE: aim is to increase quality of plates working and to decrease number of tools types and sizes used for working of different thickness plates. Apparatus for plates working has base 1, on which rotating table 2 with mean for plates fastening (drawing does not show it, the mean as a version is made as pneumatic sucker) is located; lever 3 with drive 4, on shaft of which abrasive grinding disk 5 is fixed. Grinding disk 5 is made in the form of body and disks, that form profile surface with side parts and bottom part for working of plates side surfaces. Side parts of profile surface are made with higher abrasive capability and bottom part - with lower abrasive capability and firmness. Parts of profile surface are detachable and adjustable by width. Disks are fixed on body by any known method, for example, using thermal glue. Apparatus is operating in following way. Worked plate is set on rotating table 2 and make it to rotate. Abrasive disk 5 is moved close to plate surface and also make disk to rotate using engine 4. Keeping in mind, that plates bevels are worked by tool parts of higher abrasive capability and its side surfaces - by tool parts with lower abrasive capability, then faster removal of material from plate bevels takes place and simultaneously more uniform removal of material from plate side surfaces is exercised. As disks as a version are made detachable and adjustable by width (it is possible to substitute one width disks for another width disks), it allows to work plates of different width. EFFECT: increased quality of plates working and decreased number of tools types and sizes used for working of different thickness plates. 1 dwg |
