CUT-OFF TOOLHOLDERS (SMALL DIAMETER) Main Spindle 2) When using both Main and Sub spindles In this case, when the cutting edge runs beyond the center line, the insert will contact the workpiece, since the workpiece does not fall off. Therefore the programmed distance beyond the center must be considered. e.g. When the cutting edge is programmed to run 1mm beyond the center. Workpiece maximum, 0D2 (Fig.4) = 0Dmax - 0.039"x2 (in) (The clearance between the insert and the workpiece is 0.008") Sub Spindle Fig.3 Fig.4 (When the edge is at the center) (When the edge is 0.008" beyond the center) A B Tough Edge Type T Chipbreaker Fracture Resistance Comparison (Interrupted Machining) Tough Edge Type T Chipbreaker (PR1225) 3,000 Passes Competitor A 700 Passes Competitor B 3,000 Passes Cutting Conditions Vc=250 f=0.0020ipr (Cut-Off 0.0006ipr) Wet W1 -9 (with flat cuts on two sides) TKF12R200-T-16DR (PR1225) 1,000 Passes 2,000 Passes 3,000 Passes Tough Edge Type T Chipbreaker (PR1225) Competitor A X Competitor B Worpiece (with flat cuts on two sides) X Compared to Competitor A and B, Tough Edge "T Chipbreaker" achieves superior fracture resistance during interrupted cutting.
