| 20100290853 | MULTI-PURPOSE BEVELLER - There is provided a beveller for processing an edge of a member to be processed into a slanted surface (a bevel), and, more particularly, to a multi-purpose beveller which improves a level of completion of bevel process through thoroughly processes an edge positioned at a corner by using a beveling tool for a corner mounted onto the beveller and which expands the application fields of the beveller through processing a curved section by simply replacing a rotary cutter for a corner coupled to an adapter with a cutter for a curved section. The present invention is realized by providing the technique of thoroughly processing an edge deeply positioned at a corner by selectively mounting a beveling tool for a right angled corner or a beveling tool for an acute angled corner onto the beveller, the technique of smoothly processing an edge in a corner section by sequentially separating the beveling tool for a corner and a rotary cutter for a corner coupled to an adapter and thereafter coupling a new rotary cutter for a curved section to the adapter, and the technique of applying the beveling tool for a right angled corner and the beveling tool for an acute angled corner to processing an edge in a straight-line section. | 11-18-2010 |
