Select your tool from the table from page B 284 in acc. with DIN and form (e.g. DIN 345, form C) in accordance with the machining conditions (see step 2 b C) for the relevant machining group (see step 1 P1-P15 M1-M3 O1-O6) STEP 4 Choose your cutting data from the table from page B 378 onwards Cutting speed vc Feed VRR (feed rating chart) Go to the row of your machining group (e.g. K5) and the column of your selected tool. You will find the cutting speed vc and the VRR there. The feed rating chart (VRR) can be found from page B 390 onwards. 2 cutting data for wet machining dry machining is possible, cutting data must be selected from TEC Dimensions DIN 344 DIN 343 Designation E1111 E3111 / E emulsion O oil M MQL L dry Form I1 Type 1 Dia. range (mm) 4.80 16.00 7.80 49.60 1 vc cutting speed VCRR vc rating chart from page B 382 VRR feed rating chart from page B 384 Cutting tool material HSS j Coating uncoated 11 Page B 284 B 285 1 Grouping of main material groups and identification letters Brinell hardness HB Tensile strength Rm Machining group 1 Workpiece material 5 X 5 =51 vc VRR vc VRR P C < 0.25 % annealed 125 428 P1 28 28 > 0.25 < 0.55 % annealed 190 639 P2 28 28 8 1 C > 0.25 < 0.55 % tempered 210 708 P3 26 26 8 > 0.55 % annealed 190 639 P4 28 28 8 > 0.55 % tempered 300 1013 P5 17 17 j machining steel (short-chipping) annealed 220 745 P6 28 28 j Low alloy steel annealed 175 591 P7 28 28 8 1 tempered 300 1013 P8 17 17 / tempered 380 1282 P9 6 O E i1 tempered 430 1477 P10 1 High-alloyed steel and high-alloyed tool steel annealed 200 675 P11 1 hardened and tempered 300 1013 P12 9 1 hardened and tempered 400 1361 P13 O E 1 Stainless steel ferritic/martensitic, annealed 200 675 P14 j martensitic, tempered 330 1114 P15 6 j M Stainless steel austenitic, quench hardened 200 675 M1 O E austenitic, precipitation hardened (PH) 300 1013 M2 O E austenitir/ferritir duplex 230 778 M3 O E 3 O E Li B 283 WALTER TITEX Core drilling, countersinking and centering STEP 3
