JBO thread rolling dies are fit for cold forming This is approximate because of the variety of rollable materials; it will, if materials with min. extension of approx. 8 % and up to approx. 900 N/mm² 14 necessary, be increased in steps of 0.01 mm, until the thread is fully developed. strength. The workpiece needs a chamfer of 15 - 20° for the material to startA further increase of the diameter could do harm to the tool by overload.rolling easily. Chamfer and preparing diameter need to run concentrically. Rolling speed We recommend 20 to 50 m/min. Non-ferrous metals are to be rolled in the upper speed range, free machine steel in the intermediate and difficult-to-machine steel in the lower range. Sufficient lubrication with cutting fluid is required. 140560 JBO, rigid Thread 140560  × hightmm P Workpiece mm Thread 140560  × hightmm P Workpiece mm M1,6  12.0 ×   6 0.35 1.31 M4  21,5/23 × 11 0.70 3.46 140560 (RS) M2  12.0 ×   6 0.40 1.67 M5  25.0 × 13 0.80 4.39 M2,5  12.0/16 ×   8 0.45 2.13 M6  29,5/30 × 16 1.00 5.25 M3  21,5/23 × 11 0.50 2.60 — — — — — 140580 JBO, adjustable Thread 140580  × hightmm P Workpiece mm Thread 140580  × hightmm P Workpiece mm M1,6  14.00 ×   6 0.35 1.31 M4  25.00 × 11 0.70 3.46 M2  14.00 ×   6 0.40 1.67 M5  26.70 × 13 0.80 4.39 M2,5  16.00 ×   8 0.45 2.13 M6  31.75 × 16 1.00 5.25 M3  25.00 × 11 0.50 2.60 — — — — — 140580 (RSV) Machine die HSS Bell shape Cat. no.
