Abstract

1,249,436. Electro-machining. AEGELOTHERM G.m.b.H. April 3, 1970 [Nov. 22, 1969], No. 16001/70. Heading C7B. A cavity 6<SP>1</SP>, wherein at least one crosssectional dimension increases with depth, is electrochemically countersunk in a workpiece 6 by infeeding an electrode tool 1 toward the workpiece in a planar (e.g. rectilinear, or circularly arcuate as in Fig. 3 (not shown) motion in relation to the workpiece, and simultaneously generating a pendulum motion between the tool and workpiece. As shown, the tool may be tubular, with its end closed by a perforated plate 3 and external wall covered with an instulating coating 4, and fed rectilinearly and axially by a tool holder 2. The support 5 for the workpiece 6 may be hingeably suspended on trunnions (7), Fig. 2 (not shown) in a frame 8 so that the pendulum axis is close to the workpiece surface 9 covered by an electrolyte mask 11 provided with opening 13 and annular channel 15 with sealing ring for the recirculating electrolyte entering though pipe 16 and leaving through tool interior. The invention is suitable for producing impeller blades.
