<p>PCT No. PCT/SE79/00217 Sec. 371 Date Jun. 24, 1980 Sec. 102(e) Date Jun. 16, 1980 PCT Filed Oct. 23, 1979 PCT Pub. No. WO80/00809 PCT Pub. Date May 1, 1980.According to the present invention a plurality of blanks (2) to be surface machined in working machines are placed side by side and fixed in a frame (1), open at both sides, in such a way that the blanks (2) can be machined at least at two sides while the fixation of the blanks (2) in the frame (1) is maintained. The blanks (2) are fixed tensionless in the frame (1) in such a position where the blanks bear against the frame sides on which the machining forces work during machining. The frame (1) with the blanks (2) fixed therein is first kept clamped with one side (4) resting against a machine support (6), while the portions (17) of the blanks (2) at the opposite side (5) are machined. After that the frame (1) is turned in such a way that the blanks (2) with its machine portions (17) rest against a support (6) consisting of a plane magnet plate, whereupon the blanks (2) are machined on the side (18) facing away from said support (6). The frame (1) for carrying out the method is formed at one side (4) in such a way that the blanks (2) fixed therein are available for machining from said side (4) although they are to be situated inwardly of the plane of the side (4), since this plane is to be kept fixed against a plane support during working of the fixed blanks (2) from the opposite side (5) of the frame (1) outside the plane of which side (5) the blanks (2) are intended to reach.</p> |
